Overview

This week’s papers strongly emphasize “mechanism-first” medicine: across oncology, immunology, and neurodegeneration, studies are increasingly mapping causal pathways (rather than only correlations) to identify actionable targets. In cancer, multiple reports connect therapy response or resistance to specific microenvironment programs and immunometabolic switches—ranging from ADAM8-driven immune evasion in PDAC, to AMER1–dopamine–pyroptosis licensing CD8+ T cells in colorectal cancer, to stromal circuits (e.g., midkine–TRPA1+ CAF–WNT5A–Treg) that blunt immune checkpoint blockade in gastric cancer. Parallel precision efforts include biomarker-driven stratification (e.g., genomic features predicting adjuvant mFOLFIRINOX benefit in resected PDAC; AI detection of a glioblastoma fusion) and new therapeutic modalities (next-gen ADC design principles; bispecific CAR-T strategies; STING pathway molecular glues).

Outside cancer, a dominant theme is metabolic and immune regulation as a shared thread across organ systems. Metformin’s kidney-protective mechanism in diabetic nephropathy (MAPK14–SLC7A11–GPX4) and ceramide-mediated pathways in diabetic retinopathy highlight how lipid/oxidative stress biology can be targeted to preserve function. Several studies broaden the lens: sleep/circadian disruption is framed as a modifiable cardiometabolic risk factor; early-life dietary sugar exposure is linked to reduced adult cancer incidence and slowed biological aging; and gestational hyperglycemia programs offspring cardiac disease via a CaMKIIδ O-GlcNAcylation–mtDNA axis. In neuroinflammation and neurodegeneration, lysosomal acidification and microglial lysosomal dysfunction emerge as cross-disease targets, while MS-focused work advances both biomarkers (serum GFAP dynamics) and diagnostic frameworks (2024 McDonald criteria).

Finally, the digest showcases rapid progress in tools that make these mechanisms clinically usable: AI-driven diagnostics and risk stratification (sleep-physiology foundation models; fusion detection in glioblastoma), improved monitoring/thresholding for disease change (MASLD noninvasive test trajectories), and new imaging/assay platforms (intraoperative 3D histology for glioma infiltration; spatial TCR/BCR sequencing). Together, these studies suggest a field moving toward more personalized, earlier, and mechanism-aligned interventions—supported by better measurement technologies and more granular immune and molecular mapping.

COL1A1-Enhanced CD44/SLC7A11 Interaction and Cystine Uptake Result in CD34+ Foam-Like Macrophage Accumulation in Transplant Arteriosclerosis.

This study examined how COL1A1 alters CD44/SLC7A11 interactions to drive cystine uptake and promote CD34+ foam-like macrophage accumulation in transplant arteriosclerosis. Using single-cell RNA-seq and spatial transcriptomics/integrated analyses of human allograft vasculopathy and mouse vascular allograft models, the authors found that COL1A1-enhanced CD44/SLC7A11 signaling increased cystine uptake and was linked to the emergence of CD34+ foam-like macrophages. The results identify a COL1A1–CD44/SLC7A11–cystine uptake axis as a mechanistic target for selectively modulating pathogenic macrophage subsets in chronic transplant vasculopathy.

Applying the 2024-revised McDonald criteria for multiple sclerosis using conventional diagnostic tools: a single-centre prospective cohort study in Germany.

This prospective single-centre cohort study in Germany evaluated the 2024-revised McDonald criteria for multiple sclerosis (MS) using conventional diagnostic tools in adults with a first demyelinating event or radiologically isolated syndrome (RIS). The key finding was the real-world applicability of the revised criteria for earlier MS classification compared with the 2017-revised McDonald framework in this routine diagnostic setting. Clinically, this supports adoption of the 2024 criteria—incorporating optic nerve involvement, novel MRI biomarkers, CSF kappa free light chains, and RIS classification—to improve timely MS diagnosis.

Single-cell RNA-seq and spatial transcriptomics characterize CD8+ exhausted T cells in pancreatic ductal adenocarcinoma.

This study used single-cell RNA sequencing and spatial transcriptomics to characterize CXCL13+ GZMK− CD8+ exhausted T cells (Tex) in pancreatic ductal adenocarcinoma (PDAC). The authors found that CD8+ Tex cells showed CXCL13 upregulation and GZMK downregulation, and that cell–cell interaction analyses highlighted strong communication between CD8+ Tex cells and INHBA+ macrophages as well as cancer cells. These data define a spatially informed exhausted-T-cell program and myeloid–T-cell interaction network that could inform immunotherapy stratification or combination strategies in PDAC.

Genetic Modifiers of ABCA1 Activity Interact with APOE Isoforms to Mediate Alzheimer’s Disease Risk.

This genetic association study tested whether ABCA1 variants that alter ABCA1 activity interact with APOE isoforms to modify Alzheimer’s disease (AD) risk. Using data from ADSP, UK Biobank, and European sequencing cohorts, the authors assessed AD risk across APOE ε2 and ε4 subgroups and identified statistically significant interactions between ABCA1 functional variants and APOE isoforms. The findings strengthen a mechanistic link between ABCA1-mediated lipidation and APOE-dependent AD susceptibility, suggesting that APOE genotype may modulate the impact of ABCA1 risk alleles.

Nonfermenting Gram-Negative Bacilli Other Than Pseudomonas and Acinetobacter Species in Pediatric Blood Cultures: A Multicenter European Analysis.

This multicenter retrospective European analysis studied nonfermenting Gram-negative bacilli (excluding Pseudomonas and Acinetobacter) in pediatric blood cultures collected from 56 hospitals across 25 countries between 2020 and 2024. The key finding was the species distribution and antimicrobial susceptibility patterns of these organisms under current EUCAST/CLSI guidance, highlighting their epidemiology and resistance profiles in children. Scientifically and clinically, the results fill an evidence gap for less-studied nonfermenters and can inform empiric therapy and antimicrobial stewardship in pediatric bloodstream infections.

Metabolic exhaustion and immune ageing in rheumatoid arthritis.

This review synthesized evidence on how metabolic exhaustion and immune ageing contribute to rheumatoid arthritis (RA) pathogenesis in adults, particularly those over 50 years old. The authors conclude that age-related immune remodelling and mitochondrial insufficiency across innate and adaptive lineages create a nutrient-deprived, bioenergetically fragile state characterized by NAD+ and ATP scarcity and reduced oxidative phosphorylation capacity. This mechanistic framework is significant because it points to metabolic and mitochondrial vulnerabilities as potential therapeutic targets to restore immune tolerance in RA.

A molecular glue induces aberrant STING oligomerization and inhibits autoinflammatory diseases.

This study investigated benzofuran-derived molecular glues that inhibit the stimulator of interferon genes (STING) pathway by inducing aberrant STING oligomerization. The key finding was that these compounds suppress STING activity by promoting an unconventional “head-to-head” STING dimerization configuration, leading to dysfunctional oligomerization and reduced autoinflammatory signaling. The work is significant because it provides a chemical strategy to precisely modulate STING polymerization, offering a potential therapeutic approach for STING-driven autoinflammatory diseases.

The next generation of antibody-drug conjugates.

This Nature Medicine review assessed the next generation of antibody–drug conjugates (ADCs), focusing on how monoclonal antibody–payload chemistry and mechanisms of action/resistance shape clinical performance. The authors argue that innovation is outpacing clinical trial capacity and that meaningful benefit will likely require integrating multiple chemistry advances and rational combination strategies rather than single modifications. The review is significant because it provides a framework for designing more effective ADCs and for accelerating translation of ADC improvements into patient-relevant therapies.

Bispecific ANXA2/CD147 CAR-T cell therapy for osteosarcoma.

This preclinical study developed a second-generation bispecific CAR-T targeting ANXA2 and CD147 for osteosarcoma, guided by single-cell RNA sequencing of tumor cells and validated by qRT-PCR, flow cytometry, and immunohistochemistry. The key finding was that ANXA2/CD147 bispecific CAR-T showed improved anti-osteosarcoma activity compared with single-target approaches, addressing the limited efficacy of existing single-target CAR-T therapies. This is scientifically and potentially clinically significant because it provides a rationale for dual-antigen CAR-T designs to overcome antigen heterogeneity in osteosarcoma.

The Pharmacology of CAR T Cell Therapy for Autoimmune Disease.

This review studied pharmacologic principles for cell therapies—including chimeric antigen receptor (CAR) T cells, regulatory T cells, and mesenchymal stromal cells—in autoimmune diseases. It found that conventional pharmacokinetic/pharmacodynamic dose–exposure models are inadequate because living cellular products undergo in vivo expansion, trafficking, and phenotypic evolution that drive therapeutic effects beyond short-term immunosuppression. The proposed framework is clinically significant because it can improve how autoimmune cell therapies are dosed, monitored, and mechanistically understood to support durable remission.

Impact of BMI on response to Janus kinase inhibitors in rheumatoid arthritis: an individual patient data meta-analysis of randomised controlled trials.

This individual patient data meta-analysis studied how body mass index (BMI) influences clinical response to Janus kinase (JAK) inhibitors in rheumatoid arthritis using randomized controlled trial programs. It found an association between BMI and treatment response across JAK inhibitors (tofacitinib, baricitinib, upadacitinib, and filgotinib), indicating that obesity may modify the magnitude of clinical benefit. The clinical significance is that BMI could inform expectations and potentially guide personalized treatment decisions for RA patients receiving JAK inhibitors.

Bispecific Antibodies Are Associated With Progressive Multifocal Leukoencephalopathy.

This study reviewed 5 multiple myeloma patients who developed progressive multifocal leukoencephalopathy (PML) after treatment with bispecific antibodies (BisAbs). The key finding was that BisAbs were temporally associated with PML in the setting of profound immune perturbation (e.g., plasma cell aplasia/hypogammaglobulinemia and T-cell exhaustion), with clinical presentation and CSF/imaging/pathology used to support the diagnosis and outcomes documented. These observations are clinically significant because they identify a rare but serious opportunistic complication of BisAbs and underscore the need for vigilance and biomarker-informed monitoring for PML in heavily pretreated MM patients.

Addition of High-Dose Vitamin D3 to Standard Treatment in Patients With Metastatic Colorectal Cancer: The SOLARIS Randomized Clinical Trial (Alliance A021703).

This phase 3, double-blind randomized clinical trial studied whether adding high-dose vitamin D3 to standard chemotherapy (mFOLFOX6) improves outcomes in 455 previously untreated patients with metastatic colorectal cancer (mCRC). High-dose vitamin D3 added to standard treatment improved progression-free survival (PFS) compared with standard-dose vitamin D3. If confirmed in clinical practice, vitamin D3 dose escalation could become a low-cost adjunct strategy to improve mCRC outcomes alongside mFOLFOX6.

Cancer tumor microenvironment & immunotherapy mechanisms

LZTFL1 rewires NADPH-glutathione metabolism to amplify ferroptosis.

This study identified leucine zipper transcription factor-like 1 (LZTFL1) as a regulator of ferroptosis and investigated how it rewires NADPH–glutathione metabolism in cancer models. LZTFL1 promoted oxidation of G6PD to limit NADPH production, depleted glutathione (GSH), and enhanced LZTFL1 translation via an AKT–mTOR–eIF4E feedforward loop, amplifying ferroptosis in vivo. These results position the LZTFL1–G6PD–NADPH–GSH axis as a mechanistic vulnerability for ferroptosis-based cancer therapy.

Targeting peripheral 5-HT2AR enhances antitumor immunity in colorectal cancer.

This study tested whether targeting the peripheral serotonin receptor 5-HT2AR could enhance antitumor immunity in colorectal cancer, using lysergic acid diethylamide (LSD) as a reference and developing IHCH-8110 as a non-brain-penetrant 5-HT2AR agonist. IHCH-8110 suppressed colorectal cancer growth by activating 5-HT2AR on enteric glial cells, inducing CXCL10 and boosting CD8+ T cell–mediated antitumor immunity. Clinically, this suggests a peripheral 5-HT2AR agonist strategy to harness immunostimulation while avoiding psychedelic CNS effects.

Hepatocyte MLKL drives obesity-driven hepatocellular carcinoma progression via mitochondrial dysfunction independent of necroptosis in MASLD.

This study investigated hepatocyte-intrinsic roles of mixed lineage kinase domain-like protein (MLKL) in obesity-driven metabolic dysfunction–associated steatotic liver disease (MASLD) progression to hepatocellular carcinoma (HCC), using hepatocyte-specific MLKL knockout (MlklHepKO) mice in a long-term Western diet model. Western diet increased hepatocyte MLKL protein without detectable necroptosis activation, and hepatocyte MLKL drove MASLD-HCC progression via mitochondrial dysfunction independent of necroptosis. These findings suggest that targeting hepatocyte MLKL’s mitochondrial effects could reduce obesity-associated HCC risk without relying on necroptosis inhibition.

Midkine-activated TRPA1+ cancer-associated fibroblasts promote immunotherapy resistance in gastric cancer through a WNT5A-mediated treg circuit.

This study analyzed 14 gastric cancer specimens from patients treated with neoadjuvant immune checkpoint blockade using single-cell RNA sequencing to define stromal mechanisms of immunotherapy resistance. The key finding was that midkine (MDK) maintains a LEF1-dependent TRPA1+ cancer-associated fibroblast subset under ICB pressure, which secretes WNT5A to polarize SPP1+ macrophages and promote CD25+ FOXP3+ regulatory T cell accumulation, thereby driving immunosuppression. This is clinically significant because it identifies a midkine–TRPA1+ CAF–WNT5A–Treg circuit as a mechanistic target to improve responses to ICB in gastric cancer.

Tumor stroma-immune interactions shape the immunosuppressive microenvironment and predict response to neoadjuvant chemoradiotherapy plus immunotherapy in rectal cancer.

This multicenter cohort study analyzed 498 treatment-naïve rectal cancer patients, using tumor stroma ratio (TSR) measured on H&E sections and integrative multi-omics (bulk RNA-seq and single-cell RNA/T-cell receptor profiling) to characterize stromal–immune interactions. The key finding was that the stromal-immune ecosystem defined by TSR predicts the immunosuppressive microenvironment and response to neoadjuvant chemoradiotherapy plus immunotherapy. This is clinically significant because it suggests TSR-linked stromal–immune biomarkers could help forecast treatment benefit and guide patient selection for combined modality therapy.

Tumoral AMER1 driven dopamine synthesis triggers cancer cell pyroptosis and licenses CD8+ T cell immunity in colorectal cancer.

This study investigated how tumoral AMER1 (APC membrane recruitment protein 1)–driven dopamine synthesis affects colorectal cancer (CRC) biology and antitumor immunity. It found that AMER1 in tumor cells triggers cancer cell pyroptosis and thereby licenses CD8+ T cell immunity, with AMER1 downregulation correlating with advanced CRC progression and cytotoxic CD8+ T cell spatial exclusion in patients. The findings are significant because they identify a tumor immunometabolic mechanism (AMER1–dopamine–pyroptosis) that could be leveraged to enhance CD8+ T cell–mediated responses in CRC.

A stress-adaptive lipid kinase axis defines metabolic vulnerabilities in neuroendocrine prostate cancer.

This study investigated metabolic adaptation in neuroendocrine prostate cancer (NEPC) and identified a lipid kinase axis that supports survival under hypoxia. It found that PIKfyve is overexpressed in NEPC and is required for lysosomal degradation and lipid recycling to maintain metabolic homeostasis during persistent endoplasmic reticulum (ER) stress, and that inhibiting PIKfyve disrupts lysosomal function, worsens ER stress, and activates an SREBP-dependent compensatory program. The scientific significance is that targeting PIKfyve may represent a therapeutic strategy to exploit NEPC metabolic vulnerabilities created by stress adaptation.

CIP2A-TOPBP1 complex and PP2A dynamically regulate Polθ recruitment and phosphorylation at mitotic DNA double-strand breaks.

This study engineered a TCR-mimic single-chain diabody (HI12) that recognizes a conserved Pol-derived peptide presented by HLA-A*02:01 and evaluated its effects in HLA-matched, HIV-infected humanized mice. The key finding was that HI12 administered during early ART was tolerated, activated CD8+ T cells, accelerated plasma virus decay, and produced multi-fold reductions in intact and total proviral DNA in lymph-node and splenic CD4+ T cells. The clinical significance is that targeting a conserved Pol epitope with a bispecific format may improve HIV reservoir reduction and delay viral rebound compared with Env-targeting approaches.

Co-phase separation of KRI1 and NPM1 sustains nucleolar integrity and ribosome biogenesis to fuel liver cancer progression.

This study examined how the nucleolar protein KRI1 (KRR1 interacting protein) and nucleophosmin 1 (NPM1) regulate nucleolar integrity and ribosome biogenesis to drive liver cancer progression in hepatocellular carcinoma (HCC). It found that KRI1 is aberrantly overexpressed in HCC and forms phase-separated complexes with NPM1 to maintain nucleolar structure and ribosome biogenesis, while KRI1 downregulation impaired proliferation, increased apoptosis, and disrupted nucleolar organization and ribosome biogenesis. The significance is that KRI1–NPM1 phase separation emerges as a mechanistic dependency in HCC, suggesting a potential therapeutic target to suppress ribosome biogenesis-driven tumor growth.

Deciphering the regulatory role of ADAM8 in the PDAC tumor microenvironment.

This study investigated the regulatory role of ADAM8 in the pancreatic ductal adenocarcinoma (PDAC) tumor microenvironment using CRISPR-Cas9–generated Adam8 knockout (A8KO) and wild-type (WT) PDAC cell lines, along with PDAC mouse models with or without Adam8 expression. By comparing tumor growth and microenvironmental immune components between WT and Adam8-deficient settings, the work tested whether ADAM8 drives immunosuppressive tumor progression mediated by tumor-associated macrophages (TAMs) and neutrophils (TANs). If ADAM8 is causally linked to immune evasion and poor outcomes, it could represent a therapeutic target to reprogram the PDAC microenvironment.

Comparison of NICE criteria with the BOADICEA multifactorial risk model to guide breast cancer risk assessment and referral amongst women under age 50 within primary care.

This study compared NICE breast cancer referral criteria with BOADICEA multifactorial risk model versions to identify women under 50 in UK primary care who developed breast cancer within 10 years, using 1258 Generations Study participants with family history, reproductive, lifestyle, and polygenic risk data (392 cases). The key finding was that BOADICEA-based risk assessment performed differently from NICE criteria in capturing near-term breast cancer risk among women under 50, informing how referral thresholds could be optimized beyond family-history-only approaches. This is clinically significant because it supports more accurate, model-informed identification of women who may benefit from enhanced screening and risk-reducing interventions.

Metabolic CRISPR screening identifies RPE as a key regulator of acquired enzalutamide resistance through FKBP5 destabilization in prostate cancer.

This study used an in vivo metabolic CRISPR screening approach in enzalutamide-treated castration-resistant prostate cancer xenografts to identify non-enzymatic drivers of acquired enzalutamide resistance. The key finding was that ribulose-5-phosphate 3-epimerase (RPE) promotes enzalutamide resistance by destabilizing FKBP5, and that RPE silencing markedly restored enzalutamide sensitivity. This is significant because it links a specific metabolic gene (RPE) to a defined resistance mechanism (FKBP5 destabilization), suggesting a new therapeutic target to overcome resistance to enzalutamide.

Impact of Tumor Genomic Profile on Adjuvant Chemotherapy Efficacy in Resected Pancreatic Adenocarcinoma: Results From the PRODIGE-24/CCTG PA6 Study.

This analysis evaluated how tumor genomic alterations and molecular subtypes influence adjuvant chemotherapy efficacy in resected pancreatic ductal adenocarcinoma (PDAC) from the PRODIGE-24/CCTG PA6 trial, comparing modified FOLFIRINOX (mFOLFIRINOX/mFFX) versus gemcitabine (GEM). Using tumor DNA sequencing (successful in 317/350 tumors) and transcriptomic subtyping with the PurIST classifier, the study found that specific genomic/molecular features were associated with differential benefit from mFFX versus GEM. The scientific significance is that it moves toward biomarker-guided selection of adjuvant therapy in resected PDAC, potentially improving outcomes by matching patients to the more effective regimen based on tumor molecular profile.

Early-life sugar restriction causally reduces adult cancer incidence and slows biological aging.

This study used a natural experiment from the end of UK sugar rationing in 1953 to test whether early-life sugar restriction causally affects adult cancer incidence and biological aging in UK Biobank participants born 1951–1956. Individuals whose first 1,000 days were under rationing had dose-dependent reductions in adult cancers (including liver/IHBD, rectum, lung, prostate, and breast) and showed slowed biological aging through identified pathways. These findings support early-life dietary sugar exposure as a causal determinant of long-term cancer risk and aging biology.

Palmitoylation of TK1 exacerbates osteoarthritis by promoting JNK-mediated metabolic reprogramming.

This study investigated the molecular mechanism by which thymidine kinase 1 (TK1) contributes to osteoarthritis (OA) in human articular cartilage and OA chondrocytes, integrating quantitative proteomics and reanalysis of human single-cell RNA-seq data. It found that IL-1β induces S-palmitoylation of TK1 at Cys153, which via USP9X-dependent deubiquitination prevents proteasomal degradation, leading to TK1 accumulation that scaffolds JNK signaling and drives metabolic reprogramming (including PRMT1 and PFKFB3 upregulation and excessive glycolysis) and matrix breakdown. The scientific significance is that TK1 palmitoylation–JNK metabolic rewiring identifies a mechanistic, potentially druggable axis for disease modification in OA.

GLP-1 receptor agonists in hip, knee and shoulder arthroplasty: Implications for obesity, osteoarthritis, metabolic optimisation and complications.

This article reviewed evidence on glucagon-like peptide-1 receptor (GLP-1R) agonists and related incretin therapies in patients undergoing hip, knee, and shoulder arthroplasty, focusing on implications for obesity, osteoarthritis, metabolic optimization, and perioperative complications. It reports that retrospective studies suggest preoperative GLP-1R agonist use may be associated with lower risks of periprosthetic joint infection and hospital readmission, alongside potential effects on systemic inflammation and glycemic control. Clinically, the review highlights a potentially favorable perioperative risk profile but underscores the need for more definitive prospective data to guide arthroplasty management.

Liver Endothelia Orchestrate MASH-Associated Macrophage Zonation Through FSTL1-ITGA4 Axis.

This study investigated how zonated liver sinusoidal endothelial cell (LSEC) KIT regulates macrophage zonation in metabolic dysfunction–associated steatohepatitis (MASH) using zonal LSEC isolation, endothelial-specific Kit knockout mice, spatial transcriptomics, and human data. It found that pericentral LSEC KIT maintains homeostasis by suppressing FSTL1 via STAT2 phosphorylation, while KIT loss in MASH increases centrilobular FSTL1, and the resulting FSTL1 gradient drives centrilobular accumulation of pro-inflammatory macrophages through an FSTL1–ITGA4 axis. These findings identify a specific endothelial–macrophage niche mechanism (KIT–STAT2–FSTL1–ITGA4) that could be targeted to modulate inflammatory zonation in MASH.

Creatine supplementation in patients with kidney disease - harm or benefit?

This article reviewed the evidence on creatine supplementation in people with kidney disease, focusing on potential benefits (e.g., muscle mass/strength, inflammation and oxidative stress modulation) versus concerns about renal safety. It concluded that while creatine has plausible systemic advantages relevant to chronic kidney disease (CKD) and frailty, the renal safety question remains unresolved and requires careful interpretation of existing data. Scientifically and clinically, the review frames creatine as a candidate intervention with potential harm/benefit tradeoffs that should be clarified by higher-quality trials in CKD populations.

Weight reduction-dependent/-independent effects of survodutide on liver endpoints: Mediation analysis of a phase 2 trial in MASH.

This post hoc mediation analysis studied whether weight reduction mediates liver histology and other liver endpoints improved by survodutide in participants with MASH from a phase 2 trial (NCT04771273), using causal mediation modeling. It found that the analysis quantified the proportion of survodutide’s direct treatment effect versus indirect effect mediated by percentage body-weight change, adjusting for baseline body weight, type 2 diabetes status, and fibrosis stage (F2–F3) with paired baseline/end-of-treatment biopsies. The results are clinically important because they clarify whether survodutide’s liver benefits are primarily weight-dependent or also occur through weight-independent mechanisms.

Progranulin deficiency-induced lysosomal dysfunction drives maladaptive myeloid cell states through the MITF/TFE transcription factors.

This work studied how progranulin (Grn) deficiency affects lysosomal function and drives maladaptive myeloid cell states in aged Grn-/- mice using multi-omic profiling and single-cell RNA sequencing. It identified a GPNMB+ microglial subpopulation with lysosomal stress features and showed epigenetic enrichment of MITF/TFE transcription factor motifs at active enhancers, implicating MITF/TFE-driven programs in the altered microglial state. The results connect progranulin-linked lysosomal dysfunction to transcriptional/epigenetic reprogramming of myeloid cells, highlighting MITF/TFE as potential targets to mitigate neurodegeneration-associated immune maladaptation.

Lysosomal dysfunction drives a transcriptional and epigenetic signature found in disease-associated microglia in neurodegenerative diseases.

This study investigated the mechanisms by which lysosomal dysfunction shapes microglial transcriptional and epigenetic programs in a mouse model of mucopolysaccharidosis type IIIA using SGSH (Sgsh) deficiency. In Sgsh-deficient brains, microglia were the most profoundly affected cell type, and MITF/TFE family members emerged as major drivers of microglia-specific epigenetic and transcriptional changes in a dominant and context-dependent manner. These findings support a causal role for lysosomal dysfunction in generating disease-associated microglial signatures and suggest MITF/TFE-regulated regulatory networks as mechanistic levers in neurodegenerative disease.

Mechanistic basis for calmodulin‑dependent allosteric activation of the neuropathy-associated formin INF2.

This article studied how calcium-bound calmodulin (Ca2+-CaM) allosterically activates the atypical formin INF2 by binding its diaphanous inhibitory domain (DID), using nanomolar binding assays and a high-resolution crystal structure of the Ca2+-CaM–INF2 DID complex. It showed that Ca2+-CaM binding disrupts the autoinhibitory DID–DAD interaction, triggering INF2 actin assembly activity via a mechanism distinct from canonical Rho GTPase-mediated formin regulation, including activation of ER-bound INF2. The work provides a molecular explanation for Ca2+-dependent INF2-driven actin remodeling, informing potential therapeutic strategies for INF2-associated neuropathies.

Butyrophilin-like 3 and 8 tetramers clamp Vγ4Vδ1 T cell receptors for antigen-independent activation.

This study determined the antigen-independent activation mechanism of human Vγ4Vδ1 T cell receptors by resolving the structure of the BTNL3–BTNL8 receptor complex bound to the Vγ4Vδ1 TCR. The authors found that BTNL3 and BTNL8 form an antigen-independent tetramer that clamps a head-to-head Vγ4 TCR homodimer via coordinated engagement of BTNL3 by the Vγ4 HV4 and CDR2 loops, forming a 2:2:2 BTNL3:BTNL8:Vγ4Vδ1 complex. The structural mechanism clarifies how BTNL3/BTNL8 can trigger intestinal immune responses without phosphoantigen, informing therapeutic strategies to modulate Vγ4+ T cell activity.

Co-option of retrotransposons promotes antibody diversification.

This study examined how activation-induced cytidine deaminase (AID) is targeted to immunoglobulin VH(D)JH loci during somatic hypermutation (SHM) in germinal center B cells. It discovered that evolutionarily old, truncated, retrotransposition-dead LINE-1 (L1) elements upstream of many VH genes can be activated by recombined VH promoters to produce antisense RNAs that recruit the HUSH silencing complex and AID, defining “L1-driven SHM,” which was supported by in vivo HUSH conditional knockout mice and engineered models. The work reveals a retrotransposon-based targeting mechanism for antibody diversification, expanding understanding of how SHM specificity is achieved and potentially informing interventions in antibody-related diseases.

Cell surface ADGRG1 and CD86 expression identifies antitumor CD4+ T cells in human cancer.

This study examined how the CIP2A–TOPBP1 complex and PP2A regulate DNA polymerase theta (Polθ) recruitment and phosphorylation at mitotic DNA double-strand breaks (DSBs). It found that CIP2A–TOPBP1 is recruited to mitotic DSBs, directly interacts with Polθ to corecruit it to chromatin, and sustains Polθ phosphorylation by inhibiting PP2A to prolong Polθ retention, followed by PP2A-mediated dephosphorylation and Polθ release after repair completion. The significance is that it defines a dynamic regulatory switch controlling Polθ-dependent microhomology-mediated end joining (MMEJ) during mitosis, informing how mitotic genome stability is maintained and potentially how it is exploited in cancer.

Norovirus inter-species transmission in an ex vivo model is dependent on virus internalization capacity.

This study tested whether human norovirus inter-species transmission depends on viral internalization capacity using porcine, canine, and avian precision-cut intestinal slices and human norovirus virus-like particles (VLPs). Human norovirus VLPs bound to pig and dog intestinal tissue and were taken up with efficiencies comparable to porcine and canine noroviruses, respectively, whereas no binding or internalization was observed for certain other species contexts (as truncated in the abstract). These results indicate that the ability of noroviruses to internalize into host intestinal cells is a key determinant of cross-species transmission risk.

New insights on microglial lysosomal acidification: A therapeutic target of neurodegenerative diseases.

This review examined microglial lysosomal acidification mechanisms and evaluated whether impaired lysosomal acidification is a therapeutic target and prognostic biomarker across neurodegenerative diseases. It found that defective lysosomal acidification promotes accumulation of undegraded material, driving neuroinflammation and neuronal damage, and that restoring lysosomal function in microglia could be disease-modifying. The work is scientifically significant because it frames lysosomal acidification as a cross-disease target and potential biomarker for patient stratification.

Left Ventricular Hypertrabeculation and Prognosis in Dilated Cardiomyopathy.

This study evaluated embolic risk and prognostic relevance of left ventricular (LV) hypertrabeculation (formerly LV noncompaction) across dilated cardiomyopathy (DCM) genotypes by analyzing 1,160 DCM patients with cardiac magnetic resonance imaging and genetic testing from 22 international centers. LV hypertrabeculation was assessed as a predictor of embolic events, advanced heart failure events, and major ventricular arrhythmias, with results truncated in the abstract. If confirmed, genotype-stratified risk prediction using CMR-defined hypertrabeculation could refine embolic prevention strategies in DCM.

Antithrombotic strategy according to age in patients with atrial fibrillation and drug-eluting stents: a post hoc analysis of the ADAPT AF-DES randomised trial.

This post hoc analysis of the randomized ADAPT AF-DES trial evaluated age-stratified safety and efficacy of non-vitamin K antagonist oral anticoagulant (NOAC) monotherapy versus NOAC plus clopidogrel in atrial fibrillation patients with drug-eluting stents. Patients were stratified by age (≥75 vs <75 years) and NOAC monotherapy used apixaban or rivaroxaban, with the primary endpoint being net adverse clinical events at 1 year (details truncated). The study aims to clarify whether NOAC monotherapy is a safer and effective antithrombotic strategy for older AF patients after DES implantation.

Respiratory disease & pulmonary outcomes

Improved peripheral airway reactance is associated with clinical remission following biologic therapy in severe asthma.

This retrospective study in 237 adults with GINA-defined severe asthma assessed whether oscillometry-defined small airways dysfunction (SAD) parameters predicted clinical remission after treatment with biologics or standard of care. It found that improved peripheral airway reactance measured by oscillometry was associated with subsequent clinical remission, including among patients receiving add-on biologic therapy (benralizumab, dupilumab, or tezepelumab). The result is clinically significant because it supports using noninvasive oscillometry biomarkers to identify treatable traits and forecast remission likelihood in severe asthma.

Diagnostics, imaging, AI & clinical prediction tools

Artificial intelligence-based diagnostic model for identifying PTPRZ1-MET fusion in a clinically defined secondary glioblastoma cohort.

This study developed and evaluated an AI-based diagnostic model to identify PTPRZ1–MET (ZM) fusion in a clinically defined secondary glioblastoma cohort. Analyzing 159 patients with sGBM (15 ZM-positive and 144 ZM-negative), the authors confirmed that ZM-positive tumors had significantly shorter overall and progression-free survival and used transcriptomic features to support fusion detection. The significance is that an AI diagnostic tool could enable more accurate, earlier identification of ZM fusion—an actionable prognostic driver—in routine sGBM care.

Uncovering ectopic GC-like niches for tumor reactive lymphocyte priming in lung adenocarcinoma using Stereo-XCR-seq.

This study developed Stereo-XCR-seq, a spatial transcriptomics method that retrieves and sequences T-cell receptor (TCR) and B-cell receptor (BCR) sequences from spatial transcriptome cDNA libraries at subcellular resolution. The key finding was that Stereo-XCR-seq enabled high-fidelity, unbiased recovery of XCR sequences alongside spatial context, revealing heterogeneous lymphoid aggregates and ectopic GC-like niches that support tumor-reactive lymphocyte priming in lung adenocarcinoma. This is significant because it provides a new in situ tool to map adaptive immune clonal evolution and niche organization within tumors.

Reproducibility of Biomarkers in MASLD: A Benchmark for Clinically Meaningful Change in Serially Measured Non-Invasive Tests.

This study assessed reproducibility of non-invasive tests (NITs) used to monitor metabolic-dysfunction associated steatotic liver disease (MASLD) in a Phase 2 trial screening pipeline. It found that measurement variation of serially measured NITs can be benchmarked at the patient level to define clinically meaningful change thresholds, using biopsy-confirmed at-risk MASLD participants across 198 centers in 11 countries. The scientific significance is that it improves interpretation of NIT trajectories in trials and supports more reliable detection of clinically meaningful disease change without repeat biopsy.

Ultrarapid deep 3D histology enables intraoperative mapping of glioma infiltration.

This study developed and tested ULTRA (ultrarapid cleared stimulated Raman with AI), a label-free, stain-free, fixation-free, section-free 3D histology platform for intraoperative mapping of glioma infiltration. ULTRA combines a one-step tissue-clearing protocol with stimulated Raman scattering (SRS) microscopy and unsupervised AI to enable rapid, FFPE-grade deep 3D analysis of entire specimens suitable for intraoperative consultation. The approach could improve surgical decision-making and prognostication by providing faster volumetric assessment of tumor infiltration than conventional histopathology.

Mapping the exposome-microbiota-host axis for prenatal origins of infant health.

This study profiled 1,689 mother–infant pairs to map the exposome–microbiota–host axis for prenatal origins of infant health using multiomics of 776 maternal exposome variables and meconium microbiota alongside 10 infant outcomes. Maternal anthropometrics and clinical indicators predicted infant development, while specific metabolic and chemical exposures were major drivers of neonatal microbiota composition, and microbiota changes were associated with infant growth, eczema, and neurodevelopment. The work links prenatal exposures to infant disease-relevant phenotypes through measurable microbiome-mediated mechanisms, supporting microbiota-informed prevention strategies.

Autonomous Oxygen Titration for Maintaining Normoxemia in Acutely Ill Adults: The SAVE-O2 AI Randomized Clinical Trial.

This JAMA Internal Medicine randomized clinical trial tested an AI-driven autonomous oxygen titration system to maintain normoxemia in acutely ill hospitalized adults with hypoxemia. The intervention was designed to continuously titrate supplemental oxygen flow to keep peripheral oxygen saturation (SpO2) within a predefined target range, compared with usual intermittent clinician titration (primary results truncated in the abstract). If effective, autonomous titration could reduce time spent in hypoxemia/hyperoxemia and improve oxygen management safety in acute care.

Conventional vs Video-Assisted Laryngoscopy for Perioperative Endotracheal Intubations: A Randomized Clinical Trial.

This randomized clinical trial compared conventional direct laryngoscopy versus video-assisted laryngoscopy (including hyperangulated blades) for routine perioperative endotracheal intubations, focusing on first-pass success. It found that video laryngoscopy did not provide superior first-pass success compared with direct laryngoscopy across the trial arms (regardless of blade geometry/manufacturer). The results are clinically significant because they inform which laryngoscopy approach should be prioritized for routine intubations in the operating room.

Are exercise benefits in older adults clinically meaningful?: An ancillary and follow-up analysis of a multicenter randomized controlled trial.

This ancillary follow-up analysis of a multicenter randomized controlled trial evaluated whether exercise produces clinically meaningful individual responses in 188 older adults (>75 years) with mild cognitive impairment assigned to a 3-month home-based multicomponent exercise program (Vivifrail; 3–5 days/week) versus control. Clinically meaningful response thresholds were assessed for functional ability using the Barthel Index (≥5-point improvement) and for locomotion using the short physical performance measure (≥1-point improvement). Demonstrating clinically meaningful heterogeneity would support tailoring exercise prescriptions to maximize real-world benefit in older adults.
