Overview

Across this week’s papers, a dominant theme is “precision by context”: whether it’s tailoring therapy to patient biology (e.g., post-PCI antithrombotic intensity in atrial fibrillation, trial-eligible vs ineligible enfortumab vedotin use, and biomarkers like sNfL trajectories or paramagnetic rim lesions in MS), or tailoring treatment to tumor state (e.g., epigenetic regulator inhibition to restore ATR inhibitor sensitivity, PHGDH inhibition to overcome PD-1 resistance, and state-specific CRC organoid modeling of CEACAM6/KRT19–driven chemoresistance). Multiple studies also emphasize that real-world populations and longitudinal trajectories can differ meaningfully from trial settings, strengthening the case for monitoring and risk stratification that evolves over time rather than relying on single baseline measurements.

A second major thread is the immune–microenvironment interface: cancers repeatedly show that therapeutic response is shaped by nearby cells and niches—macrophage lipid/cholesterol partnerships in leptomeningeal medulloblastoma, macrophage “bodyguards” protecting bladder tumors from cisplatin, and macrophage polarization changes driven by tumor immunometabolism (PHGDH/α-ketoglutarate). Complementing this, neuroimmune crosstalk and CNS barriers appear in multiple formats (C9ORF72 synaptic/cryptic transcript changes, neurodegeneration as a network phenomenon, and glioma brain-barrier effects on immune surveillance), suggesting that immune access and signaling architecture—rather than immune presence alone—may be a key determinant of outcomes.

Finally, several studies highlight inflammation and systemic physiology as actionable levers beyond the primary disease site: CKM staging and CRP trajectories for cardiopulmonary risk, obesity-driven metabolic inflammation shaping cancer immunity, and even social factors (loneliness/isolation) linking to mental-health–dominant pathways affecting life expectancy. Together with advances in diagnostics (multiplex PCR for TB meningitis, microbiome transmission signatures for GI cancer) and consensus frameworks (frailty in lung transplant, adult IgA vasculitis, colorectal polyp resection quality, and portal hypertension guidance), the digest points toward a broader shift: combining mechanistic insights with scalable measurement tools to improve decisions in both routine care and high-stakes settings.

Cardiovascular & Thrombosis (Antithrombotic Therapy, Collaterals, Blood Pressure)

Tracing the origins of de novo coronary collateral formation in cardiac repair.

This Science study investigated the cellular origins of de novo coronary collateral artery formation during cardiac repair using genetic lineage tracing of endothelial cell (EC) populations. Dual genetic lineage tracing showed that capillary ECs—not arterial ECs—are the major contributors to de novo collateral building blocks, and transient Vegfa expression delivered via modified mRNA markedly promoted collateral formation. These findings refine the mechanistic model of collateral genesis and suggest VEGFA mRNA–based strategies to enhance vascular repair after cardiac injury.

Triple versus double antithrombotic therapy after PCI in atrial arrhythmia: a real-world comparative analysis based on initial antithrombotic strategy using TriNetx.

This retrospective TriNetX real-world cohort study evaluated triple versus double antithrombotic therapy after PCI in adults (≥18 years) with atrial fibrillation/flutter and coronary artery disease, matched 1:1 by propensity score. Patients receiving triple therapy (oral anticoagulant plus dual antiplatelet therapy) had different rates of the composite outcome (all-cause mortality and ischemic stroke among others) compared with double therapy (oral anticoagulant plus one antiplatelet), with the analysis stratified by initial antithrombotic strategy. The findings are clinically relevant for optimizing post-PCI antithrombotic regimens in atrial arrhythmia patients where the balance between ischemic protection and bleeding risk remains uncertain.

Cardiometabolic Risk & Inflammation (CKM, CRP, Diet, Exposome, Loneliness)

A cardiometabolic perspective on post-exertional malaise in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and Long COVID.

This perspective synthesizes evidence on post-exertional malaise (PEM) in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and in individuals with Long COVID, focusing on cardiometabolic implications. It proposes that PEM may reflect disrupted coordination across interconnected physiological systems over different post-exertional timescales, leading to altered longitudinal physiological trajectories rather than only symptom flare. The significance is a shift toward longitudinal, systems-level investigation of PEM that could clarify mechanisms and identify cardiometabolic targets for ME/CFS and Long COVID care.

Associations of loneliness, social isolation and healthy lifestyle with life expectancy free of major physical disease and mental disorder.

This cohort study examined associations between loneliness, social isolation, and healthy lifestyle with life expectancy free of major physical disease and mental disorder in 277,489 adults from the UK Biobank. It found that loneliness and social isolation were more strongly associated with reduced life expectancy free of mental disorder than with life expectancy free of physical disease. The results emphasize mental-health pathways as a key mechanism connecting social factors to overall healthspan and mortality risk.

Discovery of modifiable factors associated with Pan-Cancer Risk: An Exposome-Wide analysis.

This exposome-wide study analyzed 93 modifiable exposures in 460,000+ UK Biobank participants to assess associations with 23 site-specific cancers and to evaluate combined effects with genetic susceptibility. The key finding was that an exposomic risk score (ERS) capturing multiple modifiable factors identified pan-cancer risk-relevant exposures and quantified their joint contribution alongside genetic predisposition. These results support a multi-exposure, gene-informed framework for prioritizing modifiable cancer risk factors and estimating population attributable fractions (PAFs) across cancer sites.

Unveiling the Immune Mechanisms of Hypertension With Single-Cell Transcriptome-Wide Mendelian Randomization.

This study integrated expression quantitative trait loci (eQTLs) from 14 immune cell subsets (OneK1K) with two-sample Mendelian randomization and colocalization using FinnGen and UK Biobank to identify cell type–specific causal immune genes for hypertension. It prioritized “druggable” causal eGenes based on single-cell expression patterns and compared causal eGene activity between individuals with and without hypertension. The approach provides a gene- and immune-cell–resolved framework to nominate therapeutic targets for hypertension driven by immune dysregulation.

Cumulative C-reactive protein exposure links to COPD risk in adults with cardiovascular-kidney-metabolic syndrome stages 0-3 (no overt CVD): A prospective cohort study.

This prospective cohort study examined whether cumulative exposure to C-reactive protein (CRP) predicts chronic obstructive pulmonary disease (COPD) risk in adults with cardiovascular-kidney-metabolic (CKM) syndrome stages 0–3 (no overt cardiovascular disease) using CHARLS data. CRP was measured in 2012 and 2015, and longitudinal CRP change patterns were related to incident COPD risk. The findings support CRP trajectory as a longitudinal inflammation marker for identifying adults at higher COPD risk within CKM syndrome before overt CVD.

Associations of Cardiovascular-Kidney-Metabolic Syndrome With All-Cause and Cardiovascular Death and the Progression of Cardiovascular-Kidney-Metabolic Syndrome Among Hong Kong Chinese People Over 2 Decades.

This 20-year prospective cohort study in Hong Kong Chinese community-dwelling participants (CRISPS 2; assessed 2000–2004) analyzed associations between cardiovascular-kidney-metabolic (CKM) syndrome stages and mortality, and how CKM stages progress over time. The key finding was that CKM syndrome stage is prospectively related to all-cause and cardiovascular death risk and that CKM status can worsen or progress across follow-up. The significance is that CKM staging may provide a long-term risk stratification tool for mortality and a target for earlier intervention in this population.

Association Between Cardiovascular-Kidney-Metabolic Health and Early Arterial Injury in Young Adults in the United States: The Future of Families-Cardiovascular Health Among Young Adults Study.

This FF-CHAYA (Future of Families-Cardiovascular Health Among Young Adults) study assessed how Cardiovascular-Kidney-Metabolic (CKM) syndrome staging relates to cardiovascular health (Life’s Essential 8) and early arterial injury measured by carotid artery health in young adults in the United States. CKM stage was associated with worse cardiovascular health metrics and greater evidence of early arterial injury across the CKM staging framework. These results support CKM staging as a potentially useful early risk stratification tool for identifying young adults at risk for subclinical vascular disease.

Kidney Disease & Transplantation (Proteinuria, FSGS, Transplant Outcomes)

Evaluating sparsentan for the treatment of focal segmental glomerulosclerosis.

This review evaluated sparsentan, a single-molecule dual endothelin receptor A/angiotensin II type 1 receptor antagonist, as a potential therapy for focal segmental glomerulosclerosis (FSGS) in patients with primary FSGS and persistent proteinuria despite optimized supportive care and, when used, immunosuppression. The key finding is that endothelin-1–mediated pathways are implicated in FSGS progression and that sparsentan has emerged as a novel antiproteinuric approach targeting both endothelin and angiotensin signaling. Clinically, this supports further consideration of sparsentan for reducing proteinuria and slowing kidney function decline in FSGS populations with high-risk proteinuria.

Association Between Systolic Blood Pressure Time in Target Range and Graft Outcomes in Kidney Transplant Recipients: Result From KOTRY and KNOW-KT.

This prospective observational cohort study examined whether systolic blood pressure time in target range (SBP-TTR) between 110 and 130 mmHg is associated with graft outcomes in 4559 kidney transplant recipients (KOTRY) with replication in 828 recipients (KNOW-KT). The key finding was that SBP-TTR, reflecting consistency of office blood pressure control, is associated with graft outcomes and may outperform single blood pressure measurements as a prognostic indicator. Clinically, it supports using SBP-TTR metrics to guide post-transplant blood pressure management to improve graft survival.

Aging-, obesity-, and diabetes-related sarcopenia: Pathogenesis and interventions.

This review examined how aging, obesity, and type 2 diabetes contribute to sarcopenia pathogenesis and what interventions can mitigate it in humans. It highlights resistance exercise/strength-based training as a foundational nonpharmacological approach that improves muscle mass and strength, while also summarizing emerging pharmacological strategies. Clinically, the synthesis supports prioritizing strength training in at-risk populations (older adults, people with obesity, and those with type 2 diabetes) to slow or prevent sarcopenia progression.

Impact of sex, socioeconomic deprivation, ethnicity and region on exacerbation rates and mortality of chronic respiratory diseases in England: population-based cohorts.

This population-based cohort study used linked England primary care records (GP extraction service) with Hospital Episode Statistics and Office for National Statistics mortality data to assess how sex, socioeconomic deprivation, ethnicity, and region affect asthma and COPD exacerbation rates and mortality since the start of the COVID-19 pandemic. It found that exacerbation and mortality outcomes varied across these social and demographic inequalities. The findings are significant for targeting health-system and public-health interventions to reduce inequities in chronic respiratory disease outcomes.

Dietary ketogenic ratio and all-cause mortality among adults with cardiovascular-kidney-metabolic syndrome.

This NHANES-based analysis studied whether dietary ketogenic ratio (KDR) is associated with all-cause mortality in adults with cardiovascular-kidney-metabolic (CKM) syndrome (stages 1–4), using mortality follow-up through 2019. The study reported that KDR was associated with mortality risk in this CKM population and that the relationship persisted after accounting for broader diet-quality metrics (in sensitivity analyses). Scientifically and clinically, it suggests that dietary macronutrient composition (captured by KDR) may be a modifiable risk factor for survival in CKM syndrome.

Designing a Cardiac Arrest System That Includes Extracorporeal Cardiopulmonary Resuscitation: A Contemporary Review.

This contemporary narrative review studied how to design an out-of-hospital cardiac arrest system that incorporates extracorporeal cardiopulmonary resuscitation (ECPR) rather than focusing only on procedure-level efficacy or cannulation. The key finding is that outcomes are driven largely by system-level performance (e.g., emergency medical services integration and operational design) more than by the ECPR procedure itself. Scientifically and clinically, it provides a framework for implementing ECPR-enabled systems to improve survival in refractory out-of-hospital cardiac arrest.

Oncology: Solid Tumors & Tumor Microenvironment (CRC, HCC, Melanoma, Glioma, PDAC, Prostate, Medulloblastoma, Bladder)

Isoleucine and valine promote prostate cancer progression via propionyl-CoA-mediated cholesterol metabolism.

This work studied how branched-chain amino acids isoleucine and valine promote prostate cancer progression by linking propionyl-CoA metabolism to cholesterol homeostasis in prostate cancer cells. It reports that isoleucine and valine catabolism is a primary intracellular source of propionyl-CoA, and that propionyl-CoA acts as a signaling molecule that stabilizes nuclear sterol regulatory element-binding protein (SREBP) activity to drive cholesterol synthesis and lipid droplet accumulation. The significance is identification of a propionyl-CoA–cholesterol metabolic signaling axis as a potential therapeutic vulnerability in aggressive prostate cancer.

AI-enabled discovery and biochemical optimization of minibinders targeting cancer cell-surface proteins.

This study developed and biochemically optimized AI-designed minibinders targeting cancer cell-surface proteins using mammalian cell-surface display screening and interface modeling with Chai-1 (ESM embeddings) and ipTM scoring. It found that thousands of AI designs yield several high-affinity PD-L1 minibinders, while far fewer high-affinity binders were recovered for CD276 (B7-H3) and VTCN1 (B7-H4), and that predicted interface template modeling scores correlate with binding success and identify harmful interface mutations. The approach provides a scalable pipeline to generate flow-cytometry–ready minibinders and to improve AI protein design success rates for specific tumor antigens.

Glycolytic enolase 1-induced H4K12 lactylation activates quiescent breast cancer stem-like cells in triple-negative breast cancer.

This study investigated how glycolytic enolase 1 (ENO1) regulates quiescent breast cancer stem-like cells in triple-negative breast cancer (TNBC) via histone lactylation. Using a dual-reporter system (NANOG-EGFP plus H2B-mCherry pulse-chase) and corroborating evidence from scRNA-seq of TNBC patient samples, it found that active BCSCs are enriched for glycolysis and lactylation signatures, with ENO1 expression positively associated with increased histone H4 lysine 12 lactylation (H4K12la) in the active/quiescent stem-like states. The findings link ENO1-driven lactylation to activation of quiescent TNBC stem-like cells, suggesting a potential metabolic-epigenetic target to limit tumor progression.

Safety, Biodistribution, and Dosimetry of FAP and Integrin αvβ3 Dual-Targeting Radioligand 177Lu-DOTA-FAPI-RGD: Preclinical Validation and First-in-Human Study in Patients with Advanced Adenocarcinomas.

This preclinical validation and first-in-human study evaluated the safety, biodistribution, and dosimetry of the dual-targeting radioligand 177Lu-DOTA-FAPI-RGD (177Lu-LNC1009) targeting fibroblast activation protein (FAP) and integrin αvβ3 in patients with advanced adenocarcinomas. Using HT1080-FAP and U87MG xenografts for biodistribution and then administering 2.0±0.3 GBq to nine patients selected by 68Ga-FAPI-RGD PET/CT positivity, the study assessed clinical safety and radiation dosimetry with preliminary efficacy endpoints. The work is significant for advancing a theranostic strategy that couples FAP/integrin targeting with quantitative imaging to guide radioligand therapy in advanced solid tumors.

Liver resection after atezolizumab and bevacizumab versus maintenance therapy for locally advanced hepatocellular carcinoma (TALENTOP): a multicentre, open-label, randomised, phase 3 trial.

This multicentre, open-label, randomized phase 3 trial studied whether liver resection after response to systemic therapy improves outcomes in treatment-naive locally advanced hepatocellular carcinoma patients with macrovascular invasion and no extrahepatic metastasis. The key finding was that patients assigned to liver resection after induction with intravenous atezolizumab (1200 mg every 3 weeks) plus bevacizumab (with subsequent maintenance therapy comparison) showed a survival benefit versus maintenance therapy alone. This provides clinically actionable evidence for integrating atezolizumab–bevacizumab response with surgical management in selected advanced HCC patients.

Metabolic inflammation, obesity, and cancer.

This Immunity review synthesized evidence on how obesity-driven metabolic inflammation shapes cancer susceptibility, progression, and response to therapy, focusing on immune cell reprogramming. The key finding was that metabolic stress in adipose tissue and liver drives myeloid (especially macrophage) adaptation and systemic immune remodeling that can alter antitumor immunity across tissues. This mechanistic framework is significant for designing obesity-aware immunotherapies and for targeting myeloid pathways to improve cancer outcomes.

Tumor cells recruit macrophage bodyguards to outlast chemotherapy.

This Cancer Cell study (highlighted in the journal’s commentary) examined how bladder tumor cells recruit macrophage “bodyguards” to protect against chemotherapy, focusing on spatial tumor–macrophage niches. The key finding was that EMT-like CD44^high tumor cells paired with SPP1/PARP14^high macrophages form a protective niche that drives cisplatin resistance, and that PARP14 inhibition converts this niche into an inflammatory, cisplatin-sensitizing state. Therapeutically, targeting PARP14 may overcome chemotherapy resistance by disrupting tumor–macrophage protective interactions.

Cuproptosis enters the cancer-immunity circuit.

This Cell commentary summarized a mechanistic circuit linking cuproptosis to cancer immunotherapy responses, focusing on tumor cell death pathways and T cell–mediated sensitization. The key finding was that cuproptotic tumor cells promote dendritic cell activation and CD8^+ T cell priming, while IFN-γ from T cells sensitizes tumor cells to FDX1-dependent cuproptosis, creating a self-reinforcing loop. Clinically, it provides a rationale for combining cuproptosis induction with PD-L1 blockade to overcome immunotherapy resistance.

Tumor-intrinsic PHGDH inhibition sensitizes colorectal cancer to PD-1 blockade via α-ketoglutarate-mediated macrophage reprogramming.

This work studied whether tumor-intrinsic inhibition of phosphoglycerate dehydrogenase (PHGDH), a rate-limiting enzyme in de novo serine biosynthesis, can sensitize colorectal cancer to PD-1 blockade and how this alters the tumor microenvironment. In syngeneic colorectal cancer models, pharmacologic PHGDH inhibition (and genetic PHGDH silencing) enhanced PD-1 therapy efficacy by reducing tumor-derived α-ketoglutarate and reprogramming macrophages, supported by single-cell transcriptomics and functional assays. Clinically, targeting PHGDH may overcome immunotherapy resistance in CRC by disrupting tumor immunometabolism and macrophage polarization.

Pathologic Complete Response (pCR) Rate and Predictors of Response to Taxane, Trastuzumab, and Pertuzumab in HER2‑Positive Breast Cancer: Secondary Analyses of EA1181/CompassHER2 pCR.

This analysis studied predictors of pathologic complete response (pCR) in patients with HER2-positive breast cancer treated with neoadjuvant taxane plus dual HER2 blockade (trastuzumab and pertuzumab) in the EA1181/CompassHER2 trial. In a single-arm setting, the study evaluated pCR rates and factors associated with achieving ypT0/Tis and ypN0 after four cycles of trastuzumab/pertuzumab combined with either weekly paclitaxel or every-3-weeks docetaxel. Clinically, identifying pCR predictors in this regimen can help refine response expectations and guide future neoadjuvant treatment strategies.

Exercise modulates microbial metabolites and induces stromal remodeling in pancreatic cancer.

This study analyzed tumors from pancreatic ductal adenocarcinoma (PDAC) patients in the PancFit trial and used a murine PDAC model to determine how exercise alters the tumor microenvironment through microbial metabolites and stromal remodeling. It found that exercise reduced αSMA+ cells and, in mice, decreased microbially influenced IL6-expressing inflammatory cancer-associated fibroblasts (iCAFs), linking exercise to a less inflammatory stromal state. These findings suggest that exercise benefits in PDAC may be mediated by gut microbiome–dependent stromal remodeling, informing adjunctive lifestyle or microbiome-targeted therapies.

Patient-Derived Organoid and Single-Cell Multiomics Reveal Evolution Driven by CEACAM6/KRT19-Mediated Heterogeneity.

This study used patient-derived colorectal cancer (CRC) organoids and single-cell multiomics to characterize tumor heterogeneity and evolution driven by CEACAM6/KRT19–mediated states. Across 17 treatment-naïve organoids from Chinese surgical specimens, high-throughput chemo-targeted combination screening across eight clinical regimens revealed differential responses and mechanisms of chemoresistance associated with CEACAM6/KRT19 heterogeneity. The work provides a translational platform to model and therapeutically exploit CRC cell-state evolution and drug resistance in a patient-specific manner.

Targeting epigenetic regulators induces transcription-replication conflicts to overcome ATR inhibitor resistance.

The study investigated how targeting epigenetic regulators affects transcription–replication conflicts to overcome resistance to ATR inhibitors in cancer cells, building on prior findings in wild-type and CDK8-deficient (CCNC loss) settings. Genome-wide CRISPR screening identified vulnerabilities that restore ATR inhibitor sensitivity by reintroducing replication stress through transcription-dependent mechanisms when ATR signaling is pharmacologically blocked. This suggests a combinatorial strategy—epigenetic regulator inhibition plus ATR inhibition—to counter intrinsic or acquired ATR inhibitor resistance in replication-stressed tumors.

Case Report: Ureteral obstruction reveals rare underlying fibro-inflammatory, infiltrative, and proliferative disorders: report of four cases.

This case series reported four patients in whom ureteral obstruction and periureteral “sleeve”/wall thickening on imaging revealed rare fibro-inflammatory, infiltrative, and proliferative disorders rather than malignancy. In each case, computed tomography suggested an infiltrative process, but biopsy was required to establish the underlying rare diagnosis. The report highlights the diagnostic significance of tissue sampling when imaging mimics cancer in ureteral obstruction.

Medulloblastoma Forms Symbiotic Metabolic Partnerships with Macrophages to Establish Leptomeningeal Metastases.

This preprint investigated how pediatric medulloblastoma establishes leptomeningeal metastases by forming metabolic partnerships with macrophages, distinguishing quiescent micrometastases from mitotically active macrometastases. It found that macrometastases are more lipid/cholesterol-rich and secrete CXCL12 to recruit lipid-laden macrophages, which then upregulate the cholesterol transporter ABCG1 to support tumor growth. Clinically, the CXCL12–macrophage cholesterol axis identifies a potential therapeutic vulnerability to limit leptomeningeal metastatic progression.

Efficacy and Safety of Enfortumab Vedotin by Trial Eligibility in Advanced Urothelial Carcinoma: A Multicenter Real-World Study.

This multicenter retrospective real-world study evaluated enfortumab vedotin (EV) in 180 patients with advanced urothelial carcinoma treated at Kobe University Hospital and affiliated institutions, comparing outcomes in trial-eligible versus trial-ineligible patients. Trial-ineligible status—defined using modified EV-301 eligibility criteria including severe renal impairment (eGFR <30 mL/min/1.73 m2), poor performance status, and anemia—was associated with different real-world efficacy and safety outcomes compared with trial-eligible patients. The results are clinically significant because they extend evidence for EV use to populations excluded from pivotal trials, supporting more informed treatment decisions in routine practice.

SMARCA4-deficient undifferentiated malignancies in the digestive system: clinicopathological features and prognostic significance with genomic insights from the TCGA cohort.

This clinicopathological and genomic study investigated SMARCA4-deficient undifferentiated malignancies in the digestive system using a retrospective cohort (n=43) and TCGA-based genomic insights. Immunohistochemistry identified SMARCA4 deficiency in 30.2% of cases, and the study reported clinicopathological associations and prognostic significance linked to SMARCA4 loss alongside genomic features from TCGA. These findings are scientifically and clinically important because they help define the behavior of rare undifferentiated digestive cancers and identify SMARCA4 deficiency as a potential prognostic biomarker.

Oncology: Hematologic Malignancies & Immunotherapy (CAR-T, Lymphoma, AML, Vaccines, BiTE/bsAb)

In vivo CAR T cells on the highway: a roadmap for the next decade.

The article reviews strategies to deliver chimeric antigen receptor (CAR) T cells in vivo—aiming to avoid ex vivo manufacturing—by leveraging lipid nanotechnology, RNA chemistry, and viral particle targeting in the context of hematological malignancies. It concludes that engineering CAR T cells directly in the patient’s bloodstream is supported by advanced preclinical and early clinical evidence and could reduce the logistical burden of lymphodepleting chemotherapy coordination and specialized manufacturing. If realized at scale, this approach could broaden CAR T access and accelerate next-decade development of more practical, lower-cost CAR T platforms.

Immune-cytokine signature predicts survival in patients with advanced melanoma treated with oncolytic adenovirus TILT-123 and chemotherapy and IL-2-free adoptive TIL therapy.

This correlative immunology study analyzed whether an immune-cytokine signature predicts survival in patients with advanced melanoma treated with the dual-cytokine-armed oncolytic adenovirus TILT-123 (irelimogene litadenorepvec) plus tumor-infiltrating lymphocytes (TILs) and chemotherapy, in a trial designed to avoid IL-2 post-conditioning (TUNINTIL; NCT04217473). It found that specific immune-cytokine patterns were associated with patient survival outcomes. Clinically, the signature could help stratify patients and refine selection or monitoring for IL-2-free TIL-based regimens combined with TILT-123.

Revisiting placental hypoxia in assisted reproduction: from molecular signatures to functional consequences.

This review examined placental hypoxia in assisted reproduction, linking molecular hypoxia/HIF signaling signatures to functional consequences for trophoblast development and pregnancy outcomes. It highlights that early placentation normally occurs in low-oxygen conditions and that dysregulated oxygen tension—through altered HIF signaling—can impair trophoblast specification, invasion, immune-vascular crosstalk, and angiogenesis. Scientifically, the synthesis provides a mechanistic framework for understanding how IVF/ICSI-associated changes in oxygen environment may increase placental complications.

A randomized trial of viral vector and adjuvanted protein HBV therapeutic vaccine in people with chronic hepatitis B on nucleos(t)ide analogs.

This randomized first-in-human phase 1/2 trial studied a heterologous prime-boost therapeutic vaccine strategy for chronic hepatitis B (CHB) in adults aged 18–65 who were HBeAg-negative, virally suppressed on nucleos(t)ide analogs, and had HBsAg >50 IU/mL. Participants received ChAd155-hIi-HBV (viral vector) followed by MVA-HBV, combined with sequential or concomitant administration of adjuvanted recombinant HBV proteins (HBc-HBs/AS01B), and the study assessed safety, efficacy, and immunogenicity toward functional cure. The results inform whether this vector-plus-adjuvanted-protein approach can safely induce stronger HBV immune responses in patients already on nucleos(t)ide analog therapy.

NRAS knockdown reverses monocytic cell state and resensitizes resistant FLT3-AML cells to gilteritinib.

This study tested whether NRAS knockdown can reverse monocytic differentiation state and restore sensitivity to the FLT3 inhibitor gilteritinib in FLT3-mutated acute myeloid leukemia (AML) models, including gilteritinib-resistant cell lines, in vivo cell-line-derived xenografts, and primary patient samples. The key finding was that using a mutation-agnostic antisense oligonucleotide (ASO) to deplete NRAS protein reversed the resistant monocytic cell state and resensitized resistant FLT3-AML to gilteritinib. Clinically, it supports NRAS as a mechanistic driver of gilteritinib resistance and suggests NRAS-targeted ASO strategies as a potential combination approach.

Fixed-duration epcoritamab plus R-CHOP in newly diagnosed LBCL with IPI score 3-5: results from the EPCORE NHL-2 trial.

This phase 1b/2 EPCORE NHL-2 trial evaluated fixed-duration epcoritamab plus R-CHOP in adults with newly diagnosed CD20+ large B-cell lymphoma (LBCL) and high-risk IPI scores (3–5). The key finding was that adding epcoritamab to 6 cycles of R-CHOP (total 1 year of treatment) produced efficacy outcomes (investigator-assessed overall response rate as the primary endpoint, with CR rate and survival endpoints as key secondary measures) in this poor-prognosis subgroup. The clinical significance is that it tests whether an anti-CD20/CD3 bispecific antibody strategy can improve response depth and durability compared with standard R-CHOP in high-IPI LBCL.

Continuous Evolution System Based on Toxin-Antitoxin System Combined with Base Deaminase Accelerates the In Vivo Modification of Target Proteins.

This study developed and evaluated a continuous evolution system that combines a toxin–antitoxin selection module with base deaminase activity to accelerate in vivo modification of target proteins using an improved PEACE platform in Escherichia coli. The key finding was that PEACE 2.0 increased mutation frequency (3.49×10^-3 per base pair within a 60-hour cycle) while reducing host background mutation accumulation compared with PEACE 1.0, enabling faster directed evolution of target proteins. Scientifically, it provides a more efficient in vivo protein engineering approach for generating evolved variants with less time and background noise.

Neurodegeneration & Neuroimmune Interfaces (MS, C9ORF72 FTD, Neuroimmune Crosstalk, PD initiation, Barriers)

Beyond the Cochrane review: Re-evaluating anti-amyloid therapy in Alzheimer’s disease.

This commentary re-evaluates anti-amyloid therapy for Alzheimer’s disease (AD) in light of a 2026 Cochrane review that assessed amyloid beta (Aβ)-targeting treatments. The authors argue that methodological issues—particularly a “dilution effect” from combining monomer-selective antibodies with newer therapies that target toxic Aβ plaques—may obscure cognitive benefits while amplifying perceived safety concerns. The significance is that future meta-analyses and trial interpretations should better stratify by Aβ species/target engagement to avoid prematurely dismissing potentially effective anti-amyloid strategies.

Brain barriers at the crossroads of glioma immune surveillance and immunotherapy response.

This review studied how CNS-specific brain barriers shape glioma immune surveillance and thereby influence immunotherapy response in glioma patients. It finds that specialized compartmentalizing barriers restrict immune-cell and immune-mediator access, redirecting surveillance toward the subarachnoid and perivascular spaces and contributing to limited immunotherapy efficacy. The work highlights brain-barrier biology as a mechanistic lever for improving glioma immunotherapy by modulating immune access and trafficking within the CNS.

How (We Think) Parkinson’s disease begins.

This narrative review evaluated evidence on how Parkinson’s disease initiates at molecular and systems levels, integrating neuropathology, imaging, genetics, microbiome, and immune studies. It contrasts competing initiation models—such as brain-first vs periphery-first (including olfactory and gut routes) and threshold vs multifocal frameworks—while emphasizing emerging roles for microbiome dysbiosis, endotoxin exposure, and environmental toxicants at the nose–brain interface. The significance is that clarifying PD initiation pathways could enable earlier detection and more precise, mechanism-based prevention or intervention strategies.

Neurodegeneration as a dysregulation of neuroimmune crosstalk.

This Cell perspective synthesized current evidence on neurodegeneration as a breakdown of neuroimmune crosstalk across the nervous and immune systems. The key finding was a unifying model in which immune cells and inflammatory signals act as both sensors and drivers of neuronal resilience, vulnerability, and repair, and that neurodegeneration emerges from interactions between neural and immune networks. This conceptual framework is significant for guiding future therapeutic strategies that target neuroimmune communication rather than neurons alone.

Modality-specific neurovascular coupling via layer-segregated arteriole networks.

This mouse study used multiscale optical imaging to test whether neurovascular coupling is modality-specific and mediated by layer-segregated arteriole networks during touch, nociception, motor-sensory feedback, and spontaneous activity. It showed that shallow arteriole dilation tracks superficial-layer activity, whereas deep arterioles integrate signals broadly across input conditions, with arteriole type-specific dilation decoupling local neuronal activity magnitude from capillary blood flow. The findings identify a circuit-level mechanism for how different sensory modalities dynamically regulate cerebral blood supply.

Microvascular remodeling and endothelial dysfunction across the post-COVID-19 spectrum: a prospective observational case-control study.

In a prospective observational case-control study, retinal vessel analysis (RVA) was used to compare microvascular remodeling and endothelial dysfunction across never SARS-CoV-2–infected individuals (n=96), SARS-CoV-2 recovered participants (n=102), and post-COVID-19 syndrome (PCS) patients (n=102), including a PCS subgroup meeting ME/CFS criteria (n=62). The study reports differences in dynamic and static retinal vessel parameters (DVA and SVA) across these groups, indicating microvascular alterations spanning the post-COVID-19 spectrum. Clinically, RVA provides an accessible tool to quantify microvascular health and potentially stratify cardiovascular risk in PCS and ME/CFS phenotypes.

Refining Treatment Monitoring in Patients With Relapsing Multiple Sclerosis Based on Changes on Neurofilament Light Chain Z-Scores.

This prospective real-world cohort study evaluated whether longitudinal changes in serum neurofilament light chain (sNfL) Z-scores during treatment predict subsequent evidence of disease activity (EDA) in adults with relapsing multiple sclerosis (RMS). The key finding was that on-treatment sNfL dynamics were associated with later EDA and could add complementary information beyond established treatment response scoring systems (TRSS). This supports using sNfL Z-score trajectories to refine monitoring and potentially improve treatment decisions in RMS.

Lymphatic vessels invade bone in disease but are absent in health and regeneration.

This Cell study used a Prox1-based genetic tool and a dual-recombinase-mediated LEC-specific labeling system to map lymphatic vessel localization in health, disease, and regeneration. The key finding was that LECs are present in periosteal/connective tissues but are absent from the bone parenchyma and do not invade bone to facilitate regeneration after injury. Clinically and mechanistically, it refines the role of lymphatics in skeletal repair by showing that lymphatic invasion into bone is not a feature of normal regeneration.

Distinguishing different psychiatric disorders using DDx-PRS.

The study introduces differential diagnosis–polygenic risk score (DDx-PRS) to genetically distinguish related psychiatric disorders—such as schizophrenia (SCZ), bipolar disorder (BIP), major depressive disorder (MDD), and controls—using case-control polygenic risk scores and prior clinical probabilities. It finds that DDx-PRS can jointly estimate posterior probabilities for each diagnostic category by modeling variance–covariance structure across disorders, rather than treating each disorder as an independent prediction. Scientifically, this provides a genetics-informed framework for differential diagnosis that could improve how polygenic signals are translated into clinically interpretable risk estimates.

Inhibiting cyclin D1-CDK6 suppresses senescence-associated inflammatory gene expression and age-related functional decline.

The study investigated how inhibiting cyclin D1–CDK6 affects senescence-associated inflammatory programs by examining senescent cells and age-related functional decline. It finds that cyclin D1 (CCND1) and CDK6 promote DNA damage accumulation, leading to cytoplasmic chromatin fragments that activate cGAS–STING signaling and drive SASP/ISG expression, and that blocking cyclin D1–CDK6 suppresses these inflammatory gene programs and improves age-related functional outcomes. The significance is a mechanistic and therapeutic rationale for targeting the CCND1–CDK6 axis to reduce senescence-driven inflammation and functional deterioration.

It argues that implementation fails because most models report discrimination metrics (e.g., AUC) without specifying prediction-based decision rules that map model outputs to concrete clinical actions for high- vs low-risk patients. The significance is a framework for making ADHD risk models clinically actionable, enabling safer and more effective adoption in practice.

Standardized Assessment of Complete Colorectal Polyp Resection for Polyps <20 mm (SCOPE): a Delphi Consensus.

This review examined how therapeutic targeting of G protein-coupled receptors (GPCRs) can be leveraged in central nervous system disorders, focusing on mechanisms and precision pharmacology across diseases including Parkinson’s disease, Alzheimer’s disease, multiple sclerosis, and depression. It emphasizes that dysregulated signaling through specific GPCRs—such as dopamine and adenosine A2A receptors in Parkinson’s disease, mGlu5 and muscarinic acetylcholine receptors in Alzheimer’s disease, S1P and GPR17 in multiple sclerosis, and 5-HT1A and GPR39 in depression—supports targeted drug development. The significance is that mapping disease-relevant GPCR pathways can guide more selective, mechanism-based CNS therapeutics.

RAD51 stabilizes neutrophil extracellular traps to compartmentalize inflammation.

This study investigated how neutrophil extracellular trap (NET) branching is regulated by RAD51 in the context of DNA recombination repair, using pharmacologic inhibition, RAD51 knockdown, and resolvase (GEN1 and RuvC) treatments. It found that RAD51 mediates NET branching and that RAD51 inhibition during murine pulmonary Aspergillus fumigatus infection dismantled NETs and reduced lung cytokines, although increased circulating NET components induced IL-6. The work links a specific DNA repair protein (RAD51) to NET architecture and suggests a potential target to modulate NET-driven inflammation in infection.

Multiple molecular pathways to longevity with opposing gene expression programs defining distinct aging strategies in Caenorhabditis elegans.

This eLife study used RNA sequencing to compare gene expression programs in nine long-lived Caenorhabditis elegans mutants representing seven longevity pathways. It identified multiple molecular routes to longevity defined by opposing gene expression programs, indicating that different lifespan-extending interventions converge on distinct transcriptional strategies. Scientifically, this refines the genetic logic of aging and can help prioritize pathway-specific targets for neurodegenerative disease interventions.

The UPR drives gametogenesis via an unexpected response, coordinating translation and ER structure.

This study in budding yeast showed that the endogenous unfolded protein response (UPR) that occurs before meiosis is required for gametogenesis and coordinates translation with endoplasmic reticulum (ER) structure. The authors found that this premeiotic UPR differs from previously defined UPR outputs, with only a few mildly induced UPR targets, and that disrupting the UPR compromises ER integrity (including reticulon protein foci). These findings reveal an unexpected physiological role for the UPR in reproductive development and identify ER/translation coupling as a key functional mechanism.

Cohesin promotes genomic stability by suppressing unequal sister chromatid exchange.

This yeast study investigated how the cohesin complex suppresses unequal sister chromatid exchange (USCE) between repetitive sequences to promote genomic stability. The authors found that cohesin reduces USCE rates, thereby limiting recombination events between sister chromatids at repeats and preventing genome instability. The work mechanistically links cohesin-mediated sister chromatid cohesion to suppression of a specific recombination pathway that can drive genomic rearrangements.

In vivo reconstruction of the cell lineage history of a developing mouse with DNA Typewriter, from zygote to late organogenesis.

This preprint applied DNA Typewriter, a prime-editing-based sequential recorder, to reconstruct the in vivo cell lineage history of a developing mouse from the zygote stage through late organogenesis. By writing stochastic symbolic insertions into an engineered genomic TAPE in strict temporal order, the method enabled lineage reconstruction across developmental stages. Scientifically, it extends genome editing-based lineage tracing to mammalian development, offering a scalable route to map lineage dynamics in opaque, stochastic organisms.

ESCAPE: assigning site-specific activity to covalent ligands in cells by prime editing.

This preprint introduced ESCAPE (Endogenous Site-specific Competition Assays using Prime Editors) to assign site-specific functional activity to covalent ligands in cells at the level of individual cysteine residues. The method uses prime editing to generate cysteine-to-serine substitutions that disrupt covalent binding and then quantifies changes in ligand-induced phenotypes using allele frequency-based resistance scores. This provides a scalable chemical proteomics-to-function pipeline for mapping which covalent ligand binding sites drive cellular effects.

Systematic profiling reveals broad G protein coupling and context-dependent modulation of cyclic AMP by the orphan receptor GPR139.

This study characterized the orphan GPCR GPR139 in cellular systems to define its G protein coupling profile and downstream signaling behavior. Using BRET-based G protein coupling assays, genetic G protein knockout cell lines, and second-messenger and arrestin recruitment assays, the authors found that GPR139 couples broadly to multiple G proteins and that cyclic AMP (cAMP) signaling is context-dependent. The work advances mechanistic understanding of GPR139, informing future therapeutic targeting of this receptor implicated in CNS disorders such as schizophrenia and depression.

Protein condensate as a plant sunscreen.

This study examined how the small zinc-finger protein MBS1 in plants responds to singlet oxygen (1O2) generated during photosynthesis to form condensates on chloroplast surfaces. The authors found that 1O2-induced oxidation drives MBS1 condensate formation, which screens light penetration into chloroplasts and protects plants under high-light stress. These findings identify a zinc-finger–mediated, condensate-based photoprotection mechanism that could inform strategies to engineer stress-resilient crops.

Genomes of Poaceae relatives reveal key metabolic innovations preceding the evolution of grasses.

This study sequenced genomes from Poaceae relatives (Pharus, Joinvillea, Ecdeiocolea, and Typha) to determine when key grass metabolic innovations—dual cytosolic starch and lignin biosynthetic pathways—evolved relative to the origin of grasses. It found that a lineage rho whole-genome duplication (ρWGD) drove gene family expansions underlying cytosolic starch biosynthesis, while an earlier tandem duplication of phenylalanine ammonia lyase (PAL) produced phenylalanine/tyrosine ammonia lyase (PTAL). These evolutionary genomic events clarify how duplications shaped the metabolic toolkit that enabled grass diversification and can guide comparative crop metabolic engineering.

TGW1a locus simultaneously shortens growth duration and boosts grain yield in rice.

This rice genetics study mapped the TGW1a locus (qTGW1a) encoding a flowering locus T-like protein and tested how it affects heading time, nitrogen use efficiency (NUE), grain weight, and yield in rice cultivars. It found that TGW1a interacts with and stabilizes Ghd7 and Hd1 to boost NUE and grain yield, and that promoter variation allowing intermediate TGW1a transcription (TGW1aJZ) shortens growth duration by 3.67–8.67 days while increasing grain yield by 4.22–11.00% across modern cultivars. Clinically relevant for agriculture, this provides a concrete molecular strategy to break the short-duration/high-yield trade-off in rice breeding.
