Overview
Across this week’s set of studies, a dominant theme is the move toward mechanism-informed, precision approaches—whether in oncology (ESCAT v2 actionability/resistance frameworks, cfDNA-guided metastatic breast cancer landscapes, proteomic and long-horizon biomarker discovery in prostate cancer) or in immunotherapy (systems maps of T cell exhaustion, strategies to enhance antigen presentation, and epigenetic drivers of immune evasion). Several papers also emphasize how resistance can be anticipated and countered by targeting specific metabolic or signaling dependencies (e.g., mevalonate vulnerability in gemcitabine-resistant PDAC, propionate–HLA-A/STUB1 antigen presentation, and ferroptosis induction via GPX4 inhibition), while others provide engineering platforms to expand therapeutic reach (retrotransposon-based “gene writers,” improved CRISPR outcome prediction, and mRNA potency assays).
A second major cluster centers on inflammation and host–tissue interactions spanning gut, lung, brain, and systemic aging. In gastroenterology, microbiota–metabolite pathways (taurine via microbiota after alginate) and immune axes (TFH→IL-2→Treg) are used to explain and potentially treat inflammatory bowel disease and related disorders, while liver-focused work ranges from genetic risk scoring for HCC in steatotic liver disease to targeted complement blockade in IgA nephropathy. In neuroscience and immunology, microglial and innate immune signaling repeatedly appears as a lever for disease modification—through inflammasome regulation (CK2–ASC/NLRP3, taurine–NLRP3), translational control (4E-BP1), and circuit-level mechanisms linking immune/metabolic states to behavior and pain.
Finally, multiple studies highlight translational and clinical implementation challenges: standardizing early acute heart failure care, improving diagnostic reliability in digital cytopathology, and integrating AI/personalized approaches into geriatric respiratory medicine. Public health and epidemiology contributions (measles/pertussis burden trends, ART-associated childhood cancer risk) complement the biomedical findings, underscoring that prevention, surveillance, and risk stratification remain central to reducing disease burden alongside new therapeutics.
Metabolic/Inflammation & Diet Interventions
Taurine lowers inflammaging by regulating the NLRP3 inflammasome in macrophages.
This study tested whether taurine changes with aging and whether taurine supplementation modulates inflammaging through the NLRP3 inflammasome in humans and mice, focusing on macrophage mechanisms. Aging increased circulating taurine, and elevating taurine in aged mice reduced mortality from sepsis and inflammasome-mediated inflammation by promoting taurine efflux from macrophages as a proximal step that regulates NLRP3 activation and pyroptosis. The results identify taurine as an enantiostatic regulator of NLRP3-driven inflammation and suggest a therapeutic strategy to dampen age-associated inflammatory disease.

Weight loss during intermittent fasting, not Mediterranean diet quality alone, is associated with lower inflammation: A randomized controlled trial.
This randomized controlled trial in 53 adults with metabolic risk factors compared a fully provided Mediterranean diet versus a habitual western diet for 8 weeks, followed by twice-weekly fasting days for 8 additional weeks. High-sensitivity C-reactive protein did not change during the diet-only phase, but after fasting began CRP decreased in the Mediterranean-diet group alongside greater weight loss and improved insulin sensitivity. The results indicate that weight loss during intermittent fasting—not Mediterranean diet quality alone—drives reductions in systemic inflammation.

Running in reverse: Tau redirects mitochondrial electron flow toward neurodegeneration.
This Neuron article commentary summarizes work showing that tau enters mitochondria and binds the electron transport chain component NDUFS3 to regulate reverse electron transport (RET). RET promotes tau phosphorylation, creating a self-perpetuating loop that is exacerbated by stress and tauopathy. The proposed tau–mitochondria feedback mechanism links mitochondrial electron flow to neurodegeneration and highlights RET regulation as a potential therapeutic angle.

Decoding the Safety Profile of GLP-1 Receptor Agonists: Facts, Myths, and Ongoing Controversies.
This narrative review summarized evidence on the safety profile of glucagon-like peptide-1 receptor agonists (GLP-1RAs) across organ systems in the context of expanding indications for type 2 diabetes, obesity, cardiovascular disease, and kidney disease. The review emphasizes that gastrointestinal intolerance, modest heart-rate increases, and a modest but reproducible increased risk of gallbladder/biliary disease are among the most consistent adverse effects (with other concerns discussed as myths/controversies). Clinically, it provides a framework for safer prescribing by distinguishing well-supported risks from less certain claims.

Obesity, Cardiometabolic & Endocrine Signaling
Cold activates a BH2 metabolic network promoting longevity and proteostasis.
This study examined how moderately cold temperature promotes longevity and proteostasis in the model organism Caenorhabditis elegans. Cold upregulated the biopterin-synthesis enzyme CAT-4 (GCH1 in humans), increasing dihydrobiopterin (BH2) production in muscle, which was transported to distal tissues (intestine and neurons) and converted to tetrahydrobiopterin (BH4) via DHFR-1, supporting improved proteostasis and lifespan. The findings identify a metabolite-driven BH2/BH4 signaling network as a mechanistic link between environmental temperature and organismal aging.

Functional architecture of the human insula.
The study tested how a futile Na+/K+ transport cycle contributes to energy expenditure in beige adipocytes in mouse and human models. It found that cold exposure activates a sympathetic–thyroid hormone signaling axis that induces ATP1A2 (Na+/K+-ATPase) alongside Na+ and K+ channels, amplifying bidirectional ion flux and increasing UCP1-independent energy expenditure. This identifies a specific ion-transport mechanism that could be targeted to modulate thermogenesis and metabolic health.

Host-pathogen pyrimidine metabolism drives cystic fibrosis lung disease.
The authors studied cystic fibrosis (CF) lung disease mechanisms in CFTR-mutant epithelial cells and identified metabolic drivers of airway remodeling during bacterial infection. They found activation of the de novo pyrimidine synthesis pathway (DNPPS) as a central contributor to CF lung remodeling, linking impaired mitochondrial bioenergetics to compensatory pyrimidine production. This suggests that targeting pyrimidine metabolism could modify the pro-remodeling microenvironment in CF.

Geriatric respiratory medicine 2026: from artificial intelligence to personalised management of the multimorbid patient.
This 2026 European Respiratory Review article examined how artificial intelligence and personalized approaches can be integrated into geriatric respiratory medicine for older, multimorbid patients. It highlights immunosenescence, frailty, and multimorbidity as key drivers of outcomes and identifies “pneumonia-associated sarcopenia” as a mechanism linking recurrent infections to functional decline, with suggested tools such as lung ultrasound and noninvasive respiratory support. Scientifically and clinically, it frames a shift from organ-centered to multidimensional management to improve acute and chronic respiratory care in aging populations.

Real-World Effectiveness and Tolerability of Rimegepant as Second- or Third-Line Acute Treatment for Migraine: A Prospective Observational Study.
This prospective observational real-world study evaluated effectiveness and tolerability of rimegepant 75 mg as second- or third-line acute treatment for migraine in 89 patients (76 female; mean age 40.6 years) who had prior inadequate response, intolerance, contraindication, or unsuitability to triptans and/or lasmiditan. The key finding was the observed real-world effectiveness and tolerability of rimegepant in this refractory/special-use population (specific outcomes are truncated in the abstract). This supports clinical decision-making for patients who cannot use standard acute migraine therapies by providing pragmatic evidence for rimegepant use.

Retatrutide Once Weekly for Treatment of Obstructive Sleep Apnea.
This study evaluated once-weekly subcutaneous retatrutide, an investigational triple agonist of GIP, GLP-1, and glucagon receptors, in adults with moderate-to-severe obstructive sleep apnea (OSA) with BMI ≥27 in two phase 3 double-blind randomized placebo-controlled trials (TRIUMPH-1-OSA without type 2 diabetes and TRIUMPH-2-OSA with type 2 diabetes). Retatrutide (4, 9, or 12 mg) produced a greater improvement in the primary endpoint (change in apnea-hypopnea index) than placebo. If confirmed in full results, weekly retatrutide could become a novel pharmacologic option for OSA, including in patients with and without type 2 diabetes.

Comparative efficacy and safety of subcutaneous vedolizumab versus other targeted inflammatory bowel therapies in patients with moderate to severe ulcerative colitis: a network meta-analysis update.
This network meta-analysis update studied the comparative efficacy and safety of subcutaneous vedolizumab versus other targeted therapies for moderate-to-severe ulcerative colitis using 29 randomized controlled trials. It found that, across the network, subcutaneous vedolizumab could be indirectly compared with alternative targeted inflammatory bowel disease treatments, informing relative effectiveness and safety profiles despite limited head-to-head trials. Scientifically and clinically, the analysis supports treatment decision-making by ranking options for ulcerative colitis when direct comparative evidence is sparse.

IL-2-producing TFH cells sustain Treg cell homeostasis and immune tolerance in the gut.
This study investigated how IL-2–producing follicular helper T (TFH) cells regulate regulatory T (Treg) cell homeostasis in gut-associated lymphoid tissues (GALT) in mice. It found that TFH cells produce localized IL-2 at the T cell–B cell border and interfollicular regions, and that mice selectively lacking IL-2–producing TFH cells developed colitis and fatal multiorgan inflammation due to impaired GALT Treg responses and uncontrolled effector T cell expansion. Clinically, the results identify a TFH→IL-2→Treg axis as a potential mechanistic target for preventing or treating gut inflammatory disease.

Microbiota-Taurine Pathway Links Dietary Fiber to Mucosal Healing.
This Gastroenterology study tested whether the dietary fiber–derived metabolite taurine is linked to mucosal healing via the microbiota in dextran sodium sulfate (DSS)-induced murine colitis and in relevance to ulcerative colitis (UC). Alginate promoted colitis recovery through a microbiota-dependent taurine pathway, improving survival, inflammation, barrier function, and epithelial regeneration, with metabolite profiling by CE-TOFMS and epithelial program analysis by RNA-seq. The work supports a mechanistic, microbiota-mediated therapeutic rationale for targeting the microbiota–taurine axis to enhance epithelial repair in UC.

Meta-Analysis: Safety and Effectiveness of Advanced Therapies in Inflammatory Bowel Disease Patients With Concomitant Primary Sclerosing Cholangitis.
This systematic review and meta-analysis evaluated the safety and effectiveness of advanced inflammatory bowel disease (IBD) therapies in adults with concomitant primary sclerosing cholangitis (PSC-IBD), focusing on IBD clinical remission and related outcomes. Across studies identified from MEDLINE, Embase, Cochrane, and Web of Science up to July 2026, the analysis synthesized rates of clinical response, corticosteroid-free remission, mucosal healing, adverse event-related discontinuation, and colorectal neoplasia. The results are important for guiding treatment selection in PSC-IBD, where evidence on advanced biologics/small molecules has been limited.

Ravulizumab in IgA Nephropathy - Interim Analysis of a Phase 3 Trial.
This interim analysis of a phase 3 randomized trial studied ravulizumab, a terminal complement C5 inhibitor, in adults with IgA nephropathy who had persistent proteinuria despite standard therapy. Ravulizumab prevented downstream complement activation (blocking formation of C5a and C5b-9) and was evaluated for efficacy and safety outcomes related to renal disease progression. If confirmed in the full trial, these results would support C5 blockade as a targeted complement-based therapy to reduce hematuria/proteinuria and preserve kidney function in IgA nephropathy.

The hidden effects of metabolism-disrupting agents on alcohol-related liver disease risk: an integrated epidemiological, machine learning, and network toxicology Analysis.
This integrated epidemiological, machine learning, and network toxicology analysis studied 40 metabolism-disrupting agents (MDAs) and their association with alcohol-related liver disease (ALD) risk in 13,472 participants from the US National Health and Nutrition Examination Survey (2005–2016). It found that specific MDA exposures were associated with ALD risk and that combined/interactive effects could amplify alcohol-related hepatotoxicity at the population level. Scientifically, the work supports a synergistic model of alcohol plus MDA exposure and provides a data-driven framework for identifying high-risk chemical classes (e.g., PFAS, phthalate metabolites, PAH metabolites, volatile organic compound metabolites) relevant to ALD prevention.

The aMAP Score Effectively Stratifies Hepatocellular Carcinoma Risk in the Steatotic Liver Disease Population.
This study assessed whether the aMAP score, originally developed for hepatocellular carcinoma (HCC) risk prediction mainly in viral hepatitis, can stratify HCC risk in steatotic liver disease (SLD) populations. Using 156,406 SLD participants from UK Biobank and 3,166 SLD patients with virally suppressed chronic hepatitis B from a Chinese cohort, the authors evaluated predictive and stratification performance of aMAP versus PAGE-B, mPAGE-B, CAMD, and MASLD-HCC scores. If validated, the aMAP score could improve risk-based surveillance and prevention strategies for HCC in SLD, a growing indication for liver cancer screening.

SIK3 controls synaptic localization of NMDA receptors by phosphorylating GluN1.
The study developed HRDPath, an explainable multi-model deep learning architecture to predict homologous recombination deficiency (HRD) status from whole slide histopathology images in high-grade serous tubo-ovarian carcinoma (HGSOC). It found that HRDPath achieved an AUC of 0.846 across three female patient cohorts and outperformed previously reported approaches without requiring additional molecular testing. This supports a more accessible, patient-level HRD biomarker workflow that could improve selection of HRD-targeted therapies.

Actionable genetic landscape and dynamics in circulating DNA from 12,827 patients with metastatic breast cancer.
This study analyzed circulating tumor DNA by profiling 15,564 plasma cfDNA samples from 12,827 patients with metastatic breast cancer (MBC) using Guardant360 deep sequencing and a random-forest model to classify MBC subtypes. Most patients harbored variants associated with therapeutic resistance and targetability across approved and experimental therapies, including alterations in PIK3CA, ESR1, PTEN, and AKT1, with actionable frequencies differing from primary tumors and multiple variants per gene suggesting independent clonal dynamics. The resulting actionable genetic landscape and temporal dynamics support cfDNA-guided treatment selection and monitoring in MBC.

Histone deacetylase inhibition induces an antitumor IRF8-dependent trained immunity-like status in macrophages.
The authors tested whether histone deacetylase inhibition (HDACi) can induce a trained immunity-like antitumor state in macrophages and identified the key regulator. HDACi priming established an IRF8-dependent inflammatory program in monocytes/macrophages, conferring potent antitumor effects in multiple triple-negative breast cancer (TNBC) models in female mice, with IRF8 controlled by IRF8-associated super-enhancers and reinforced by HDACi. This positions IRF8 as a master switch for epigenetically induced trained immunity-like macrophage function, offering a potential strategy to enhance innate antitumor responses.

Propionate promotes MHC class I antigen presentation and anti-tumor immunity.
This Cell Metabolism study tested whether the short-chain fatty acid propionate enhances tumor antigen presentation and anti-tumor immunity. Propionate increased MHC class I antigen presentation by stabilizing HLA-A and promoting STUB1-mediated K168/K170 polyubiquitination and degradation, leading to greater CD8+ T cell infiltration/activation and reduced tumor growth. These mechanistic and functional findings suggest propionate or STUB1–HLA-A pathway modulation as a strategy to improve immune recognition and potentially checkpoint blockade responsiveness.

Glofitamab with polatuzumab vedotin in relapsed/refractory central nervous system lymphomas.
This retrospective study assessed the safety and activity of the bispecific antibody glofitamab combined with the antibody-drug conjugate polatuzumab vedotin in 9 patients with relapsed/refractory central nervous system lymphoma (CNSL). The combination produced a 100% overall response rate and 89% complete response rate, including responses in high-risk subtypes such as chemorefractory Burkitt lymphoma and TP53-mutant mantle cell lymphoma. These results suggest a promising blood-brain-barrier–penetrant regimen for otherwise poor-prognosis r/r CNSL.

CREBBP loss drives immune evasion by epigenetically silencing STING and MHC-I in small cell lung cancer.
The study investigated how CREBBP loss affects immune evasion in small cell lung cancer (SCLC) using Rb1/Trp53-driven autochthonous mouse models and syngeneic SCLC models, focusing on epigenetic regulation of STING and MHC-I. CREBBP deletion promoted immune escape by epigenetically silencing STING and MHC-I through reduced histone H3 acetylation, and HDAC inhibition restored acetylation and reactivated these genes. These findings identify CREBBP-dependent epigenetic control of innate and antigen-presentation pathways as a driver of immunotherapy resistance in SCLC.

WEE1 opposes APC/CCDH1 activity to promote S phase entry.
This study explored how the kinase WEE1 regulates cell-cycle transitions by opposing APC/C^CDH1 activity to promote S phase entry, focusing on cell-cycle control mechanisms relevant to WEE1 inhibitor biology. The authors report that WEE1 promotes cell-cycle re-entry from quiescence (G0) by counteracting the E3 ubiquitin ligase APC/C^CDH1, revealing functions beyond the canonical G2 DNA damage checkpoint. Scientifically, this clarifies why WEE1 inhibitors can have effects in TP53-wild-type contexts and may guide strategies to improve therapeutic selectivity and reduce toxicity.

GRP75-dependent SIMPA mediates inter-organellar quality control.
The study investigated GRP75-dependent SIMPA-mediated inter-organellar quality control in cells under proteostatic stress, focusing on how damaged mitochondrial proteins are handled. It found that proteostatic stress drives damaged mitochondrial proteins into stress-induced mitochondrial protein aggregates (SIMPA) that activate coordinated mitochondrial quality control mechanisms via GRP75. This reveals a specific molecular relay linking mitochondrial proteostasis damage to broader organellar surveillance, informing how cells maintain mitochondrial integrity during stress.

The rise of reducing reagent-resistant TfR1 dimer marks ferroptosis.
The study developed and validated a ferroptosis detection strategy based on a reducing reagent-resistant (3R) dimer of transferrin receptor 1 (TfR1) in cells, tissues, and extracellular vesicles. It found that the 3R TfR1 dimer specifically increases when ferroptosis is induced pharmacologically or genetically, and it can detect disease-associated ferroptosis in mouse and patient plasma-derived extracellular vesicles. This provides a potentially scalable, near-ubiquitous biomarker for ferroptosis to support translational studies.

Cerebral blood flow as a biomarker of resilience in cognitively unimpaired APOE ɛ4 carriers.
This study examined whether medial temporal lobe (MTL) cerebral blood flow (CBF) measured by pseudo-continuous arterial spin labeling MRI serves as a biomarker of resilience in cognitively unimpaired older adults who were APOE ε4 carriers versus noncarriers. APOE ε4 carriers showed higher MTL CBF, and the relationship between MTL CBF and cognition differed by APOE status and AD pathology status indexed by plasma pTau217 in a subset. The findings suggest that preserved or elevated MTL perfusion may reflect resilience rather than dysfunction in some APOE ε4 carriers, supporting CBF as a potential stratification biomarker for preclinical AD risk.

Persistent neuronal stress signalling underlies Angelman syndrome phenotypes.
This study investigated Angelman syndrome mechanisms by using gain- and loss-of-function mutations in UBE3A and unbiased proteomics to identify downstream targets in UBE3A-related models, including Ube3a-null mice and human neurons. It found that asparagine synthetase (ASNS) is a UBE3A target, with increased ASNS abundance in Ube3a-null mouse brains and human neurons, and that correcting ASNS overabundance rescues microcephaly and multiple behavioral deficits. These results connect UBE3A loss to a specific substrate pathway and suggest ASNS/ASNS-regulated biology as a potential therapeutic lever for Angelman syndrome.

Apelin-13 prevents GATA4-mediated neuronal senescence by restoring autophagy through mTORC1 inhibition.
The authors tested whether apelin-13 prevents D-galactose-induced neuronal senescence by using SH-SY5Y cells, human iPSC-derived neurons (iPSC-NDs), and an aging mouse model, and they used the APJ agonist ML233. Apelin-13/ML233 attenuated neuronal senescence and brain aging/cognitive impairment in these models, restoring autophagy through mTORC1 inhibition. This supports the APJ–mTORC1–autophagy pathway as a mechanistic target for reducing neuronal senescence and age-related cognitive decline.

Serum β-synuclein predicts dementia conversion and mortality beyond amyloid-β and phospho-tau.
This study assessed whether serum β-synuclein predicts dementia conversion and mortality beyond established CSF amyloid-β and tau biomarkers in 259 non-demented individuals with subjective or mild cognitive impairment from a memory clinic. The key finding was that serum β-synuclein added prognostic value for dementia conversion and mortality independent of CSF Aβ42/Aβ40 and pTau181 status (full statistical details are truncated). Scientifically and clinically, it supports β-synuclein as a potentially useful blood-based synaptic biomarker for risk stratification in preclinical Alzheimer’s disease.

An autonomous macrophage-nociceptor mechanosensory relay drives chronic visceral pain.
This study investigated whether immune cells directly transduce mechanical cues into nociceptive signaling in colitis-associated visceral pain by examining Piezo1 function in tissue-resident CX3CR1+ macrophages in mouse models. Piezo1 activation triggered calcium influx and NF-κB nuclear translocation to drive NGF synthesis from macrophages, and macrophage-derived NGF sensitized TRPV1+ nociceptor terminals to produce chronic visceral hypersensitivity. The work establishes an autonomous macrophage–nociceptor mechanosensory relay centered on Piezo1–NF-κB–NGF as a mechanistic target for treating visceral pain in inflammatory bowel disease.

A futile Na+ K+ transport cycle augments energy expenditure in beige adipocytes.
The study investigated how the kinase SIK3 controls synaptic localization of NMDA receptors by phosphorylating the obligatory subunit GluN1. It found that SIK3 localizes to synapses and phosphorylates GluN1 at a single site that is required for recruiting NMDARs to synapses, with SIK3 deletion reducing synaptic GluN1 levels by ~60% without major effects on AMPA receptors. This defines a precise post-translational control point for NMDAR synaptic positioning, with implications for synaptic computation and neurological disorders.

Integration of hydrogen peroxide sensing and detoxification by the C. elegans nervous system.
This Current Biology study mapped the neural circuit in Caenorhabditis elegans that drives chemotactic escape from environmental hydrogen peroxide (H2O2). It showed that H2O2 sensing begins when H2O2 oxidizes peroxiredoxin PRDX-2 cysteines, which relays the signal to LITE-1 and GUR-3 ion channels to trigger calcium influx and escape behavior. The work links a defined oxidative-sensing mechanism to specific ion channels and neural outputs, advancing circuit-level understanding of reactive chemical threat responses.

A GABAergic preoptic-raphe circuit mediates paradoxical coupling of anxiety and social preference after comparative social deficit.
This study examined a neural circuit in adult male mice using a comparative social deficit (CSD) model to link anxiety-like behavior with social preference. CSD increased excitability of medial preoptic GABAergic (mPOAGad2) neurons, and transcriptomic/electrophysiological analyses identified downregulation of the Kv4.3 potassium channel (Kcnd3) as a molecular driver. These findings define a GABAergic preoptic-raphe circuit and ion-channel mechanism that may explain loneliness-like, paradoxical anxiety/social phenotypes relevant to anxiety disorders.

Multiple allosteric sites allow for synergistic enhancement of GPCR signaling.
The study elucidated cooperative multisite allostery in the dopamine D1 receptor (D1R) by developing two new D1R positive allosteric modulators (UNC9815 and UNC10062) and determining receptor structures. Cryo-electron microscopy identified two previously uncharacterized D1R allosteric sites occupied by UNC9815/UNC10062 and showed how these sites cooperate with another PAM site bound by BMS-A1 to enhance GPCR signaling. This mechanistic framework advances the rational design of multisite allosteric drugs for GPCR-targeted therapeutics.

Acetaminophen-induced liver injury triggers short- and long-term neuroinflammation, blood-brain barrier disruption, and behavioral deficits in a genetic mouse model of autism.
This study tested whether acetaminophen (APAP)-induced acute liver injury exacerbates ASD-like phenotypes in a genetic mouse model by using adult Shank3-/- mice and wild-type controls. A single high-dose APAP challenge triggered short- and long-term neuroinflammation, blood-brain barrier disruption, and behavioral deficits measured acutely (24 hours) and one month later. The results are significant because they link peripheral drug-induced liver injury to worsening neuroimmune and behavioral ASD-relevant outcomes in a genetically susceptible background, suggesting liver injury as a modifiable risk amplifier.

Microglial protein kinase CK2 prevents obesity in mice potentially through NLRP3 inflammasome activation.
The study investigated how microglial protein kinase CK2 regulates metabolic homeostasis in mice using microglia-specific inducible deletion of the CK2 regulatory subunit β (CK2β). CK2β-deficient mice developed obesity with weight gain, impaired glucose homeostasis, and reduced energy expenditure, and mechanistically CK2 phosphorylated ASC at T154 to enable ASC aggregation and NLRP3 inflammasome-driven IL-18 maturation/release. These results link microglial CK2 signaling to NLRP3 inflammasome activation as a potential therapeutic axis for obesity and metabolic dysfunction.

Translational control of microglial metabolism, inflammatory responses, and survival by the eIF4E-binding proteins.
This work studied how eukaryotic translation initiation factor 4E-binding proteins (4E-BP1/2), regulated downstream of mTORC1, control microglial metabolism, inflammatory responses, and survival in the context of Alzheimer’s disease. Elevated cerebrospinal fluid (CSF) 4E-BP1 levels were associated with microglial reactivity and disease progression, and the authors report that translational control via 4E-BPs modulates microglial inflammatory and survival programs (full mechanistic details are truncated). The findings suggest that CSF 4E-BP1 could be a clinically relevant biomarker and that targeting the 4E-BP translational axis may modulate neuroinflammation.

Oropouche virus disrupts neurodevelopment and exhibits congenital infection potential.
The study examined whether Oropouche virus (OROV) can infect the developing human brain and cause congenital neurodevelopmental pathology using human forebrain organoids and neonatal mice. It found that OROV infects neurons across differentiation states in forebrain organoids and shows heightened neuroinfection and pathology compared with Zika virus (ZIKV), with broader neuronal tropism contributing to increased permissiveness. This strengthens the evidence that OROV is a congenital neurotropic pathogen and highlights mechanisms that may inform risk assessment and countermeasure development.

Structure and functional divergence of the non-canonical BoNT-like toxin PG1 and PG2.
This work characterized the structure and function of two non-canonical BoNT-like toxins, PG1 and PG2, whose light-chain (LC) and heavy-chain (HC) domains are encoded by adjacent genes. PG1 and PG2 LCs cleave Drosophila SNAP-25 at distinct sites (N196-E197 vs R191-K193), with PG1 being more potent and PG2 activity depending on pH and ionic strength, while LC entry into Sf9 cells occurs via clathrin-mediated endocytosis. The study clarifies how domain architecture and cleavage-site specificity shape toxin potency and regulation, informing mechanistic understanding of BoNT-like toxin evolution.

RIPK3 acts as a molecular switch between neuroprotection and neuropathology during herpes simplex encephalitis.
Using single-cell transcriptomics, genetic knockout models, and measurements of viral replication, interferon production, and cell death, the study examined how RIPK3 influences outcomes during herpes simplex encephalitis (HSV-1) across CNS cell types. RIPK3 acted as a cell-type-specific molecular switch: RIPK3 scaffolding promoted interferon responses and viral control in multiple CNS populations, while RIPK3-dependent apoptosis limited pathology in myeloid cells. These findings explain how RIPK3 can be protective or harmful depending on cell context, guiding potential host-directed strategies for HSV encephalitis.

A phage DUF669 protein mediates post-cleavage DNA repair against host CRISPR immunity.
The study investigated a phage anti-CRISPR countermeasure called Healer, composed of Gp63 (DUF669) and Gp64 (AAA), against host CRISPR immunity. Gp63 rapidly binds ssDNA generated by CRISPR cleavage and promotes Gp64-mediated homologous recombination to repair DNA breaks, enabling phage replication despite CRISPR attack. This reveals a post-cleavage DNA repair-based anti-CRISPR mechanism that expands how phages neutralize CRISPR defenses.

Diverse infection models demonstrate robust resistance of Mycobacterium tuberculosis to innate immunity.
The study examined how innate immunity controls Mycobacterium tuberculosis (Mtb) using ultra-low dose infections in C57BL/6 mice and by immune priming via co-housing with “pet shop” mice. The authors found that the initial innate immune response could not curb even minimal Mtb infectious doses, indicating strong innate resistance of Mtb in vivo. This supports the idea that adaptive immunity is required for effective early control of Mtb and that standard SPF mouse models and high inocula may mask innate immune effects.

The Need for a Validity-Based Diagnostic Hierarchy in DSM-6.
This article argues for restoring a validity-based diagnostic hierarchy for DSM-6 to address diagnostic proliferation and overlapping criteria that reduce construct validity. It critiques the post-DSM-III shift toward reliability over parsimony and proposes that DSM-6 should reintroduce a hierarchy grounded in etiology/pathology rather than symptom clusters treated as separate disorders. The significance is methodological: a hierarchical, validity-driven DSM could improve clinical interpretation of comorbidity and reduce confusion in psychiatric diagnosis.

It found multiple neutrophil subsets with distinct functions and robust, condition-specific changes in gene expression and subset proportions across infection, cancer, immune suppression, and sex differences, with conserved and species-specific features revealed by cross-species mapping. The scientific significance is that SCAHN provides a high-resolution reference for interpreting neutrophil states in diverse diseases and for guiding future mechanistic and therapeutic studies.

Spatial confinement promotes germinal center diversity and tempers immunodominance.
This mouse study examined how reduced germinal center (GC) confinement affects GC B cell diversification and immunodominance using Gα13-dependent G-protein-coupled receptor signaling deficiency to create de-confined GCs. It found that de-confined GCs showed less diversification across neighboring GC color palettes, increased clonal crossover between neighboring GCs, and altered repertoire dynamics compared with confined GCs. The significance is that spatial confinement is a functional regulator of GC evolutionary processes, shaping how B cell clones diversify and compete during immune responses.

Graft-versus-host disease prophylaxis shapes T cell biology and immune reconstitution after hematopoietic cell transplant.
The study compared T cell immune reconstitution after hematopoietic cell transplant using posttransplant cyclophosphamide (PT-Cy) versus tacrolimus/methotrexate (Tac/MTX) GVHD prophylaxis in 324 coenrolled patients from BMT CTN 1801, using longitudinal TCR repertoire sequencing of 2359 samples. PT-Cy-based prophylaxis produced distinct T cell biology and immune reconstitution pathways relative to Tac/MTX, aligning with the superior GVHD-free/relapse-free survival observed in the phase 3 BMT CTN 1703 trial. These results provide mechanistic insight into how GVHD prophylaxis regimens shape T cell recovery, informing optimization of transplant immunosuppression.

CD28 costimulation is organized by signaling condensates and counteracted by PD-1.
The study investigated how CD28 costimulation is spatially organized in T cells by testing whether CD28 intracellular domain (ICD) forms signaling condensates with the Src-family kinase Lck and how PD-1 counteracts this process. Ligand engagement rapidly triggered CD28/Lck condensation, increasing CD28 phosphorylation, cytoskeletal polarization, and cytokine production, with downstream effectors such as PI3K and GRB2 recruited into the condensates in a reconstituted system, while PD-1 disrupted this signaling organization. This mechanistic insight links checkpoint signaling (PD-1) to physical control of TCR–costimulation microarchitecture, informing how immune suppression may be engineered or targeted.

Lysosomal protein transmembrane 5 protects against myocardial ischemia-reperfusion injury by promoting mitophagy via the NEDD4-LC3 axis.
This study tested whether lysosomal protein transmembrane 5 (LAPTM5) protects against myocardial ischemia-reperfusion injury by promoting mitophagy through a NEDD4–LC3 axis using LAPTM5 knockout mice and cardiomyocyte-targeted AAV9-cTnT-LAPTM5. LAPTM5 promoted mitophagy during cardiac I/R injury, with mechanistic support from mt-Keima imaging, LC3–mitochondrial colocalization, and NEDD4 gain- and loss-of-function experiments, implicating the NEDD4–LC3 pathway and p62 ubiquitination in the protective mechanism. These results identify LAPTM5–NEDD4–LC3 signaling as a potential therapeutic target to reduce mitochondrial damage in ischemic heart disease.

Dynamic force sensing by bone delays aging and extends lifespan.
This study examined how osteocyte mechanosensing influences whole-body aging in mice by deleting the mechanosensitive channel Piezo1 and by applying dynamic tibial axial loading (DTAL) in aged animals. Reduced Piezo1-dependent mechano-sensing accelerated aging, whereas DTAL at 20–24 months extended healthspan and lifespan and reversed bone marrow immunosenescence while shifting cytokine/immunologic programs toward anti-aging and away from pro-inflammatory states. These findings support bone Piezo1-mediated mechanotransduction as a modifiable driver of systemic aging and suggest DTAL as a potential intervention to improve late-life immune function.

Patient-derived separation-of-function mutations reveal specific role for BRCA1 coiled coil domain in genome stability.
The study used isogenic chicken DT40 cell lines to model patient BRCA1 separation-of-function founder mutations, focusing on the BRCA1 coiled-coil domain variant L1407P-equivalent. Whole-genome sequencing showed that this coiled-coil mutant increased base-substitution mutagenesis without causing deletions or large-scale genomic instability, consistent with preserved DNA double-strand break repair and sister chromatid exchange promotion. These findings pinpoint the BRCA1 coiled-coil domain as a domain-specific determinant of genome stability outcomes, informing how inherited BRCA1 variants may differentially drive cancer risk.

Protein arginine methylation promotes global 3’UTR shortening in proliferating cells.
This study tested how protein arginine methylation affects mRNA 3’UTR length in proliferating cells and cancer-relevant systems. Arginine methylation promoted global 3’UTR shortening by enhancing PCF11 association with cleavage and polyadenylation machinery, and inhibiting asymmetric dimethylation (and more strongly combined asymmetric+symmetric inhibition) reversed the shift across human cancer cell lines, patient-derived organoids, and activated murine T cells. This mechanistic link between PRMT activity and 3’UTR isoform switching supports arginine methylation as a therapeutic vulnerability in proliferative and tumor contexts.

The Cas9 nickase produced efficient, allele-selective CAG/CTG repeat contractions with no detectable off-target mutations and was associated with phenotypic improvements in the mouse model. This supports repeat-contraction genome editing as a potential disease-modifying approach for HD and related CAG/CTG repeat disorders.

A Recurrent 3’UTR Variant in CAPN3 Highlights the Diagnostic Impact of Non-Coding Variants in Limb-Girdle Muscular Dystrophies.
This study investigated a novel recurrent CAPN3 3’ untranslated region (3’UTR) variant (c.*534T>C) in individuals with persistent hyperCKemia, most with proximal muscle weakness, to clarify the diagnostic impact of non-coding variants in limb-girdle muscular dystrophies. Through clinical evaluation including muscle biopsy and muscle MRI in variant carriers, the authors linked the CAPN3 3’UTR change to functional relevance for disease mechanism. The work is significant because it supports incorporating non-coding CAPN3 variants into genetic diagnostics for muscular dystrophy when coding-region testing is negative.

Interobserver variability in the interpretation of Papanicolaou tests using the Hologic Genius Digital Diagnostics System: detailed analysis of cytology verification in a large academic laboratory.
This study evaluated interobserver variability in interpreting ThinPrep Papanicolaou tests digitized on the Hologic Genius Digital Diagnostics System (HGDDS) among trained users, using a cytology verification dataset from a large academic laboratory. Across 110 cases enriched for LSIL+ and NILM with microorganisms, performance and variability were assessed for neoplasia detection and for specific cytology categories, highlighting how user interpretation differs even after HGDDS training. The findings are clinically significant for standardizing AI-assisted cervical screening workflows and for improving reliability and quality assurance in digital cytopathology.

Deep dynamical models of single-cell multiomic velocities predict loss-of-function and rescue perturbations in B cells.
This study introduced DynaVelo, a generative neural ordinary differential equation model that learns joint gene expression and transcription factor (TF) motif activity dynamics from single-cell multiome data to predict perturbation outcomes in B cells. It found that DynaVelo recovers bifurcating in vivo dynamics of wild-type murine germinal center (GC) B cells and predicts how dynamics change under heterozygous loss of epigenetic regulators Arid1a and Ctcf, producing dynamic, cell-state-specific gene regulatory networks in silico. The scientific significance is that multiomic velocity modeling can forecast loss-of-function and rescue perturbations, enabling more targeted hypothesis generation for B cell regulatory mechanisms.

Programmable design of functional proteins from natural language.
This study presents Pinal, a 16-billion-parameter protein foundation model that designs functional proteins from natural-language descriptions of desired molecular tasks. Trained on 1.7 billion synthetically annotated protein–text pairs, Pinal links functional intent to predicted protein sequence and structure to generate candidate proteins. The approach is significant for accelerating protein engineering by reducing the need for manual constraint specification or starting from existing natural proteins.

The anatomy of a personal health agent.
This work describes the design of a “personal health agent” that reasons over multimodal inputs from consumer wellness devices and medical records, informed by user research and analysis of web search/health forum queries. The authors identify four user journeys (general knowledge, personal data interpretation, wellness advice, and symptom assessment) and implement three specialist sub-agents to cover these tasks. The study is significant because it frames how large language models can be structured to deliver individualized, context-aware health support in everyday settings.

Global and regional burden of measles and vaccine coverage among children under 5 years, 1990-2023: a Global Burden of Disease Study.
This study used the Global Burden of Disease (GBD) 2023 model to quantify measles incidence, mortality, DALYs, and vaccine coverage (MCV1/MCV2) among children under 5 across 204 countries and territories from 1990–2023. Global measles incidence and mortality fell substantially from 1990 to 2019 (about 80% and 90%, respectively), but the authors report evidence of measles resurgence linked to stagnating vaccine coverage. These findings highlight where and when immunization coverage needs acceleration to prevent renewed measles transmission and deaths in young children.

Global, regional and national burden of pertussis in 1990-2023: a Global Burden of Disease study.
This GBD 2023 analysis estimated global, regional, and national pertussis incidence, mortality, and DALYs from 1990–2023 across 204 countries and territories, focusing on age-standardized trends. The study found long-term declines overall, with age-standardized mortality decreasing by 61.2% and age-standardized incidence by 41.6%, despite pandemic-era fluctuations and subsequent rebounds. The results quantify the remaining pertussis burden and support targeted infant-focused prevention strategies where incidence and mortality are not improving.

Childhood Cancer Risk After Assisted Reproductive Technology.
This nationwide Danish cohort study assessed childhood cancer risk after assisted reproductive technology (ART) in 1,086,136 live-born children (37,228 conceived via ART) with follow-up through 2023, stratifying by ART modality (IVF, intracytoplasmic sperm injection, frozen embryo transfer) and cancer type. The key finding was the presence/absence of specific associations between ART exposure and incident childhood cancers by procedure and cancer subtype (details truncated in the abstract). Clinically, the results inform counseling and risk-benefit discussions for ART use by clarifying whether particular ART methods are linked to distinct childhood cancer outcomes.
