PubMed Trending Research Digest — October 16, 2026

Automated digest · 97 articles · 15 research areas · October 16, 2026

Overview

Across this week’s set of studies, a dominant theme is the push toward precision—using biomarkers, genomics, and computational methods to stratify patients and tailor therapies. Examples include tumor DNA methylation subtypes predicting response to perioperative immune checkpoint inhibitor–based therapy in esophageal cancer, longitudinal whole-genome/exome analyses clarifying divergent evolutionary trajectories in IDH-mutant gliomas, and large-scale variant mapping (structural variants and microexons) that refines how genetic variation translates into disease-relevant biology. In parallel, clinical implementation is being standardized through living guidelines (e.g., liquid biopsy use in advanced biliary tract cancer) and through risk/eligibility modeling for high-cost therapies such as amyloid-targeting antibodies.

A second major thread is immunology as both mechanism and therapeutic target, spanning engineered immune modulation and innate immune signaling pathways. Several studies focus on improving the therapeutic window of immunomodulators (e.g., myeloid-selective IL-10 receptor agonism), while others dissect how pathways like STING, inflammasomes, and macrophage–stromal feedback loops shape inflammation and tumor immunity. These mechanistic insights are paired with translational directions: programmable protease design for targeted protein cleavage, ferroptosis-inducing strategies that bypass canonical checkpoints, and context-dependent regulators (such as PPARδ compartment effects) that may explain why immunotherapy outcomes vary.

Finally, the digest highlights growing integration of systems biology with clinical and translational goals. Multi-omics and spatial approaches (exercise-induced multi-tissue atlases, spatial transcriptomics in tuberculosis niches, and host–microbe co-transcriptomics in nodules) are increasingly used to map complex biological states in situ. Meanwhile, real-world and observational datasets (e.g., AI phenotyping of brown adipose tissue, registry-based relapse predictors in multiple sclerosis, and cardiovascular risk prediction in younger adults) emphasize scalable risk identification beyond traditional single-measure clinical endpoints.

Hematologic Malignancies: ALL and Targeted Immunotherapy/TKIs

Ponatinib-Blinatumomab or Imatinib-Chemotherapy for Adult Ph-Positive ALL.

This randomized frontline trial studied ponatinib plus blinatumomab versus imatinib plus chemotherapy in adult patients with Philadelphia chromosome–positive (Ph+) acute lymphoblastic leukemia (ALL). The intervention strategy (ponatinib + blinatumomab) was compared against the imatinib/chemotherapy control with event-free survival as the primary endpoint, with crossover allowed for measurable residual disease persistence or reappearance. If improved event-free survival is confirmed, this regimen could establish a new standard first-line immunotherapy–TKI combination for Ph+ ALL in adults.

Prognostic utility of Oxford MEST-C classification for allograft failure in transplant IgA nephropathy: A systematic review and meta-analysis.

This systematic review and meta-analysis evaluated the prognostic utility of the Oxford MEST-C classification components for allograft failure in transplant immunoglobulin A nephropathy (IgAN). Pooled hazard ratios from included studies were used to quantify how each MEST-C element (and overall scoring) predicts graft loss, using random-effects models and heterogeneity analyses. Clinically, clarifying which MEST-C features best forecast transplant outcomes could improve risk stratification and post-transplant management for IgAN patients.

Infectious Disease: Toxoplasma and Host–Pathogen Mechanisms

Identification of a spatially organized TREM2-associated permissive macrophage niche in human pulmonary tuberculosis alveolar pneumonia.

This study analyzed human pulmonary tuberculosis (Mtb) lung biopsies from four men using spatial transcriptomics, single-cell RNA sequencing, high-resolution imaging, and functional assays to compare alveolar pneumonia versus adjacent granulomas. Alveolar TB pneumonia was enriched for TREM2+ lipid-laden macrophages with increased lipid metabolism gene expression, reduced T cell infiltration, attenuated antimicrobial gene expression, and abundant Mtb transcripts/antigen. These findings define a spatially organized TREM2-associated permissive macrophage niche that could be targeted to limit Mtb burden during TB alveolar pneumonia.

Encrypting the message: Bacterium turns host RNA into a target.

This commentary discusses findings from Legionella pneumophila showing a bacterial effector that modifies host messenger RNA (mRNA) rather than host proteins to dampen host inflammatory responses. The key concept is that the bacterium “turns host RNA into a target” to control inflammation. This reframes bacterial immune evasion as an RNA-targeting strategy and suggests new directions for studying host–pathogen interactions.

Proteotyping reactivant toxoplasmic encephalitis reveals virulence-associated dense granule protein GRA5 polymorphisms.

This study investigated virulence-associated polymorphisms in the dense granule protein GRA5 of Toxoplasma gondii by proteotyping cerebrospinal fluid (CSF) from three cases of reactivated toxoplasmic encephalitis. Using CSF peptide detection alongside multilocus PCR-RFLP genotyping (ToxoDB PCR-RFLP genotype #7), the authors identified GRA5 polymorphisms linked to virulence in the reactivating strain. These findings suggest that strain-specific GRA5 variants may help explain differential pathogenic potential and could inform future molecular risk assessment in toxoplasmic reactivation.

Pediatric/Adolescent Oncology: Targeted Therapies (RET) and Safety/Efficacy

Safety and efficacy of delpacibart zotadirsen in Duchenne muscular dystrophy mutations amenable to exon 44 skipping in the USA (EXPLORE44): a randomised, placebo-controlled, double-blind, phase 1/2 trial.

This randomized, placebo-controlled, double-blind phase 1/2 trial (EXPLORE44) evaluated delpacibart zotadirsen (del-zota; AOC 1044), an antibody–oligonucleotide conjugate delivering an exon 44–skipping phosphorodiamidate morpholino oligomer, in USA participants with Duchenne muscular dystrophy mutations amenable to exon 44 skipping (DMD44). The study assessed safety, tolerability, pharmacokinetics/pharmacodynamics, and efficacy in a first-in-human design (full efficacy and safety results are truncated in the abstract). If effective and safe, del-zota could represent a targeted exon-skipping therapy to restore dystrophin expression in DMD44 patients.

Radiation Oncology & Prostate Cancer Salvage Strategies

Outcomes of Complex Retinal Detachment Repair with Proliferative Vitreoretinopathy Grade C using the Cincinnati Methotrexate Protocol.

This retrospective non-randomized comparative cohort study evaluated intravitreal methotrexate using the Cincinnati Methotrexate (MTX) protocol in 300 eyes undergoing vitrectomy for retinal detachment (RD) with proliferative vitreoretinopathy (PVR) grade C between 2019 and 2025. The MTX protocol group (150 eyes) showed improved complex RD repair outcomes compared with a 150-eye comparison cohort (details truncated in the abstract). If confirmed in full results, this MTX delivery strategy could provide a clinically actionable adjunct to vitrectomy for high-grade PVR RD to reduce failure and improve anatomical/functional recovery.

Dose-Escalated Focal Salvage High-Dose-Rate Brachytherapy and Genomic Classifier Risk Stratification in Radiorecurrent Prostate Cancer: The F-SHARP Phase I/II Clinical Trial.

The F-SHARP phase I/II trial studied dose-escalated focal salvage high-dose-rate brachytherapy (DE-fsHDR) and genomic classifier (GC)–based risk stratification in patients with intraprostatic radiorecurrence (IPR) of prostate cancer after prior definitive radiotherapy. The primary endpoint was acute grade ≥3 genitourinary and GI toxicity (CTCAE v4.03), with GC used to identify patients who might benefit from treatment intensification. If DE-fsHDR is both safe and effective and GC meaningfully stratifies benefit, this could refine post-radiation salvage strategies for radiorecurrent prostate cancer.

Brain–Gut–Microbiome & Neuropsychiatric Comorbidity (Depression/IBS)

Akkermansia muciniphila protects against endometritis through a tyrosol-mediated gut-uterus axis.

The study examined whether Akkermansia muciniphila (AKK) protects against endometritis via a gut–uterus axis mediated by tyrosol, using endometritis cows and mouse models. AKK depletion was observed in endometritis cows, gut microbiota transplantation from endometritis cows induced endometritis in mice, and supplementation with live AKK (but not heat-inactivated AKK) or AKK culture supernatant alleviated E. coli-induced endometritis, with metabolomics implicating tyrosol. This identifies a specific microbe–metabolite pathway that could be leveraged to prevent or treat endometritis.

The Brain-Gut-Microbiome Axis: Exploring the Link Between Depression and Irritable Bowel Syndrome.

This narrative review examined the brain–gut–microbiome axis as a mechanistic link between depression and irritable bowel syndrome (IBS). It highlights how dysregulated bidirectional signaling—through microbial metabolites, neuroimmune pathways, and stress-responsive neuroendocrine mechanisms—may contribute to both gastrointestinal and psychiatric disease. Scientifically, consolidating these multi-omics and neuroimaging insights supports development of microbiome- and immune-targeted hypotheses for comorbid IBS and major depressive disorder (MDD).

Immunotherapy Engineering & Innate Immune Modulation (IL-10, STING, Inflammasome)

Mitochondria-targeted tetraoxanes initiate lipid peroxidation to drive ferroptosis and tumor suppression.

The study developed mitochondria-targeted tetraoxane compounds (WMK-1/2) designed to initiate lipid peroxidation and ferroptosis in vivo, aiming to bypass reliance on GPX4 and FSP1. WMK-1 localized to mitochondria, induced local lipid peroxidation, impaired oxidative phosphorylation, and triggered a “mito-ferroptosis” pathway that skips GPX4 inhibition to suppress tumors. This provides a strategy for more effective ferroptosis induction in cancer by directly initiating mitochondrial lipid peroxidation.

Cellular self-organization orchestrates ferroptosis propagation.

The study investigated how cellular self-organization constrains propagation of ferroptosis, focusing on collective trigger-wave behavior and the role of transcriptional state boundaries. It found that cell density and alignment encode programs that prime regions for ferroptosis sensitivity (low-density, misaligned, elevated YAP/TEAD1) while forming propagation-resistant boundaries (high-density, aligned, increased NRF2), with cell elongation establishing polarized organization. These results explain how tissue-level patterning can limit ferroptosis spread and suggest design principles for controlling ferroptosis in therapeutic contexts.

Bone Marrow Macrophage STING Signaling is a Direct Nexus Linking Marrow Adipose Expansion to NAD+ Depletion and Osteogenic Decline in Skeletal Aging.

This preclinical study investigated bone marrow macrophage (BMM) STING signaling in skeletal aging, focusing on how marrow adipose expansion affects NAD+ depletion and osteogenic decline. It found that BMM STING signaling has a dual age-dependent role: STING deficiency worsens early bone development/maturation but protects against age-related bone loss from midlife onward, mediated by adipocyte-secreted soluble DPP4 that activates Toll-like receptor 4 on BMMs in concert with mitochondrial DNA to trigger STING. The significance is that STING-pathway modulation in BMMs may represent a mechanistic therapeutic target to prevent or treat age-associated bone loss.

Mitochondrial Quality Control in Degenerative Musculoskeletal Diseases: Signaling Networks and Therapeutic Landscapes.

This review studied mitochondrial quality control (MQC) mechanisms and their signaling networks in degenerative musculoskeletal diseases, including osteoarthritis (OA), intervertebral disc degeneration (IVDD), and osteoporosis (OP). It found that MQC collapse can release mitochondrial DNA fragments that activate innate immunity via the cGAS–STING pathway and can also drive epigenetic remodeling through histone lactylation, potentially creating a “metabolic memory” that sustains inflammation-metabolism dysregulation. The significance is that MQC/cGAS–STING–linked pathways may define therapeutic targets and guide drug development across multiple degenerative musculoskeletal conditions.

Targeting Macrophage STING O-GlcNAcylation via Small-Molecule Allosteric Modulation for Psoriasis Therapy.

This preclinical study investigated whether targeting macrophage STING O-GlcNAcylation with a small molecule can treat psoriasis. It found that the natural small molecule paeoniflorin (PF) selectively inhibits STING O-GlcNAcylation by binding the STING cyclic dinucleotide-binding domain (CBD), inducing an allosteric conformational shift that traps STING in an inactive open state and sterically blocks OGT recruitment to STING. The significance is therapeutic: PF (or PF-derived strategies) could provide a more selective way to dampen STING-driven psoriatic inflammation by targeting a disease-associated post-translational modification.

Evidence for maternal autoantibodies in the pathogenesis of preterm birth.

This study examined whether maternal autoantibodies contribute to preterm birth by profiling pregnancy sera using proteome-wide autoantibody profiling across large human cohorts. It identified a shared autoreactive signature associated with preterm birth, including antibodies to IL1 receptor antagonist (IL1RA), by comparing preterm versus term pregnancies across multiple cohorts. These findings implicate specific maternal immune reactivity in preterm birth pathogenesis and suggest candidate biomarkers or therapeutic targets for preventing or stratifying risk.

Compartment-specific PPARδ activity controls the outcome of cancer-immune cell competition and immunotherapy efficacy.

This mechanistic study investigated how compartment-specific PPARδ activity shapes cancer–immune cell competition and affects immunotherapy efficacy. It found that activating PPARδ in cancer cells promotes tumor growth and impairs antitumor immunity, whereas activating PPARδ in immune cells drives tumor suppression and can override tumor-promoting effects, with CD8+ T cell fitness supported by effector-associated chromatin remodeling and Cpt1a-mediated fatty-acid metabolism. Scientifically, it identifies PPARδ as a context-dependent regulator and provides a rationale for targeting PPARδ in specific compartments to improve immunotherapy outcomes.

Engineered TYK2 dependence enables myeloid-selective IL-10 receptor agonism.

The study investigated IL-10 signalling dependence on JAK-family kinase pairing in myeloid cells versus T cells and used this to engineer a tetravalent nanobody-based myeloid-selective IL-10 receptor agonist (msIL-10R agonist). The engineered agonist fully recapitulated IL-10 suppression of monocytes, macrophages, and dendritic cells while avoiding IL-10-driven T-cell stimulation by exploiting differential TYK2/JAK dependence. This provides a strategy to widen the therapeutic window for IL-10-based immunomodulation in chronic inflammatory disease by improving cell-type selectivity.

Chromatin modifiers KMT2D, cBAF, and p300 cooperatively facilitate de novo binding of transcription factors on enhancers.

The study investigated how chromatin modifiers KMT2D, cBAF, and p300 cooperate to facilitate de novo transcription factor binding on enhancers, using MyoD as a model muscle lineage-determining transcription factor. Using a nuclear translocation system, it showed that within one hour half of induced MyoD binding sites were co-occupied by KMT2D, cBAF, and p300, and that acute KMT2D depletion or short-term inhibition of cBAF or p300 enzymatic activity reduced de novo MyoD binding. This clarifies a cooperative chromatin “priming” mechanism that governs how transcription factors establish new enhancer occupancy during gene regulation.

A self-amplifying IL-1β-CCL2 circuit between macrophages and cancer-associated fibroblasts drives colorectal cancer progression.

This study investigated how macrophage–cancer-associated fibroblast (CAF) interactions drive colorectal cancer progression by identifying a self-amplifying IL-1β–CCL2 inflammatory circuit. Integrated single-cell transcriptomics of human colorectal cancer showed expansion of IL1B-associated inflammatory macrophages and IL1R1+ inflammatory CAFs, with combined signatures linked to worse disease progression, and the circuit centered on monocyte-derived IL-1β+ macrophages engaging IL1R1+ CAFs. These results highlight a targetable macrophage–CAF feedback loop that could be exploited to disrupt pro-tumor inflammation in colorectal cancer.

Extracellular vesicle-associated LMP1 from EBV-positive nasopharyngeal carcinoma induces LIF-mediated immunosuppressive macrophage polarization and impairs anti-tumor immunity.

This study examined how extracellular vesicle (EV)-associated Epstein–Barr virus (EBV) latent membrane protein 1 (LMP1) affects tumor immunity in EBV-positive nasopharyngeal carcinoma (NPC). Single-cell transcriptomics and functional experiments showed that NPC-derived EVs are taken up by macrophages, where EV-LMP1 activates NF-κB signaling to induce LIF-mediated immunosuppressive macrophage polarization and increases TAM proportions, impairing anti-tumor immunity. The identified EV-LMP1–NF-κB–LIF axis provides a mechanistic target to reverse macrophage-mediated immunosuppression in EBV+ NPC.

MDK+ cancer-associated fibroblasts promote immunotherapy resistance through mitochondrial reprogramming in breast cancer.

This study integrated single-cell and spatial transcriptomic data from breast cancer cohorts treated with immune checkpoint inhibitors to identify resistance-associated cellular populations, then validated findings using multiple bulk RNA-seq immunotherapy cohorts and functional experiments. It found that MDK+ cancer-associated fibroblasts promote immunotherapy resistance through mitochondrial reprogramming, supported by analyses of mitochondrial function and metabolic alterations in co-culture and in vivo models. These results suggest MDK+ CAFs and their mitochondrial programs as potential biomarkers and therapeutic targets to overcome anti–PD-1 resistance in breast cancer.

Antibody-mediated encephalitides: distinct diseases with transdisciplinary implications.

This narrative review discusses antibody-mediated encephalitides, emphasizing that disorders targeting glial aquaporin-4 and myelin oligodendrocyte glycoprotein are distinct entities with specific targets, mechanisms, syndromes, and treatment implications. It contrasts these with neuronal-antigen autoimmune encephalitides, which are often analyzed collectively rather than as separate diseases, and summarizes evidence for anti-NMDA receptor–related syndromes (details truncated in the abstract). The clinical significance is improved diagnostic framing and more tailored immunotherapy decisions based on the specific antibody target and disease mechanism.

STING engages PKR to drive lysosomal cell death in lung ischemia-reperfusion injury.

This study tested how STING couples to lysosomal cell death during lung ischemia-reperfusion injury in mouse and rat models and in human lung epithelial cells. Mitochondrial DNA release activated the cGAS–STING pathway to drive lysosomal cell death, with STING oligomerization inducing autophosphorylation of PKR at serine 33 and activating IκB kinase–NF-κB signaling independently of canonical STING–TBK1 and PKR–eIF2α routes. The results define PKR as an effector linking STING to lysosomal death, highlighting potential targets to modulate inflammatory lung injury.

Long-term confinement triggers RIPK3-independent necroptosis in amoeboid cancer cells to shape tumor evolution.

This study investigated how long-term mechanical confinement affects death pathways in amoeboid cancer cells by inducing a long-term mesenchymal–amoeboid transition (L-MAT) in vitro. L-MAT triggered RIPK3-independent necroptosis via a PIEZO1–STAT1 axis that upregulated MLKL, whose membrane accumulation drove necroptotic death even when death-receptor signaling was resistant. These findings connect mechanical tumor microenvironments to alternative necroptosis programs that can shape tumor evolution and therapy resistance.

CNPY3 variants associated with a recessive developmental and epileptic encephalopathy affect inflammasome and TLR function.

This genetic and functional study examined 50 individuals from 38 families with biallelic CNPY3 variants causing developmental and epileptic encephalopathy (DEE) and tested selected variants for effects on protein stability/localization and immune signaling. The key finding was that CNPY3 variants impair inflammasome activation and toll-like receptor (TLR) function (including TLR2-dependent activity) in ways consistent with disrupted ER chaperone roles. These results are significant because they connect CNPY3 loss-of-function to innate immune dysregulation, offering mechanistic targets for DEE associated with immune pathway dysfunction.

HnRNPK suppresses macrophage-driven inflammation in autoimmune myocarditis by restraining NCF1-dependent oxidized phospholipid signaling and ferroptosis-related changes.

This study investigated how the RNA-binding protein HnRNPK regulates macrophage-driven inflammation in experimental autoimmune myocarditis (EAM), focusing on NCF1-dependent oxidized phospholipid (OxPL) signaling and ferroptosis-related changes. The key finding was that HnRNPK is downregulated in EAM tissues and inflammatory macrophages, and that AAV-mediated HnRNPK administration attenuates myocardial inflammatory infiltration, fibrosis, and cardiac injury. This is significant because it identifies an upstream post-transcriptional regulator that could be targeted to reduce macrophage oxidative stress, OxPL signaling, and ferroptosis in autoimmune cardiac inflammation.

Phase 2 Trial of Icotrokinra for Patients with Ulcerative Colitis.

This phase 2b double-blind randomized trial tested oral icotrokinra, a peptide that blocks the interleukin-23 receptor, in adults with moderately to severely active ulcerative colitis. The key finding was the assessment of clinical response at week 12 across icotrokinra doses (400 mg, 200 mg, 100 mg once daily) versus placebo, with secondary evaluation of remission and endoscopic improvement. If effective, this would be scientifically and clinically important because it provides an oral IL-23R-targeting alternative to intravenous or subcutaneous biologics for ulcerative colitis.

Intravenous administration of a PHP.eB vector overexpressing neuronal Caveolin-1 delays motor neuron and neuromuscular degeneration in a TDP-43 mouse model of ALS.

This preclinical study tested systemic delivery of an AAV-PHP.eB vector expressing neuronal caveolin-1 (AAV-PHP.eB-SynCav1) in TDP-43A315T mouse models of amyotrophic lateral sclerosis (ALS). SynCav1-treated mice showed preserved motor neuron morphology, maintained neuromuscular junction innervation, and normalization of pathologically driven neurotrophic transcription in the spinal cord at 24 weeks, with immunoblotting indicating increased calcium-impermeable GluA2 in membrane lipid rafts. The results support caveolin-1 as a potential disease-modifying target and provide translational rationale for AAV-PHP.eB systemic gene delivery in TDP-43–driven ALS.

Synthetic/Developmental Biology & Embryo Modeling

Modelling mouse embryogenesis from chemically induced totipotent stem cells.

The study developed conditions to model mouse embryogenesis ex utero starting from chemically induced totipotent-like stem cells (ciTotiSCs) and tracked development through morula, blastocyst, and post-gastrulation stages. ciTotiSCs self-organized into blastocyst-like structures with morphology and lineage segregation resembling natural blastocysts, enabling continuous embryo-model development with embryonic and extraembryonic compartments. This advances synthetic/developmental biology by providing a controllable platform to study early mammalian development and totipotency-like behavior.

AI/Big-Data Phenotyping & Risk Prediction (BAT, Cardiovascular, Genomics atlases)

Genome-wide CRISPR screen reveals that Wnt signaling regulates lipid accumulation in APOE4 oligodendrocytes.

The study used a genome-wide CRISPR screen combined with ATAC-seq in human iPSC-derived APOE4 oligodendrocytes to identify regulators of APOE4-driven lipid droplet accumulation. Decreased Wnt signaling and overactive GSK3B were identified as key drivers, and genetic or pharmacologic inhibition of GSK3B reduced lipid droplet accumulation. This provides a pathway-level mechanism connecting APOE4 to oligodendrocyte lipid dysregulation and suggests GSK3B/Wnt axis modulation as a therapeutic strategy to preserve myelination.

It revealed hundreds of new microexons, including autism-relevant splicing patterns and microexons that can trigger nonsense-mediated mRNA decay, and it defined a microexon regulatory code linking genetic variation to splicing outcomes. These results provide a systematic framework for understanding how autism-linked variants may disrupt microexon regulation and neuronal gene expression.

Structural basis of ligand recognition and gating in mosquito IRs.

This study used cryo-electron microscopy (cryo-EM) and functional validation to determine the structural basis of ligand recognition and gating in mosquito ionotropic receptors, focusing on the IR8a–IR75k complex from Anopheles stephensi. The authors solved cryo-EM structures of the receptor in multiple states (apo closed, ligand-induced open, and nonanoic acid/octanoic acid–bound conformations) and linked these conformations to channel activation by carboxylic acids. The work clarifies how specific ligands gate insect IR channels, providing a mechanistic framework for targeting mosquito olfaction.

Multi-omic profiling of 85 iPSC lines from familial dementia reveals cellular diversity and regulators of organoid development.

Researchers performed multi-omic profiling of 85 human induced pluripotent stem cell (iPSC) lines carrying MAPT mutations and isogenic controls using whole-genome sequencing, long-read sequencing of the MAPT locus, bulk and single-cell RNA-seq, and DNA methylation arrays. Single-cell analyses identified four reproducible iPSC states with candidate surface markers, and whole-genome sequencing detected unintended editing events across lines. This systematic characterization helps distinguish MAPT mutation–driven biology from iPSC state variation and genome-editing artifacts for downstream organoid and disease modeling.

Differentiating pituitary metastasis from hypophysitis: A two-center study using conventional MRI and clinical features.

In a two-center retrospective cohort of 64 patients (34 pituitary metastases, 30 hypophysitis), the study evaluated conventional MRI features and basic clinical variables to distinguish pituitary metastasis from hypophysitis. The key finding was identification of clinically applicable predictors from 13 conventional MRI features (assessed by two blinded neuroradiologists) and maximum lesion size, alongside clinical factors such as cancer history, to improve diagnostic discrimination. This matters because accurate differentiation guides management pathways that differ substantially between metastatic disease and inflammatory hypophysitis.

A telomere-to-telomere map of somatic mutation burden and functional impact in a cancer.

The study constructed a telomere-to-telomere (T2T) near-telomere-to-telomere map of somatic mutation burden and functional impact by combining a near-T2T diploid assembly with deep short- and long-read sequencing of a melanoma donor. It found that 16% of somatic variants occur in sequences absent from GRCh38, with satellite repeats acting as UV mutagenesis hotspots, and it highlighted centromere kinetochore binding domains as focal sites for chromosome arm aneuploidy breakpoints and somatic variation also present in non-cancerous tissues. This improves detection and interpretation of cancer mutations in previously inaccessible genomic regions and clarifies structural-genomic drivers of mutational processes.

Antagonistic roles of histone H3 lysine methyltransferases dictate tumor immune surveillance.

This work investigated how histone H3 lysine methyltransferases, particularly SETD2-mediated H3K36 trimethylation, interact with the oncogenic H3K36M allele in KRAS-driven lung cancer models. Although H3K36M dominantly inhibits SETD2/H3K36 methyltransferases, H3K36M expression paradoxically suppressed tumor growth by promoting repetitive-element transcription, cytoplasmic dsRNA accumulation, and antiviral-like immune clearance, and these effects required SETD2 activity. The study identifies a SETD2-dependent mechanism by which an H3K36M oncogenic state can trigger immune surveillance, informing epigenetic-immune therapeutic strategies in lung cancer.

Musculoskeletal & Metabolic Disease Mechanisms (OA, Exercise, Aging, Hypogonadism, Muscle Atrophy)

Recovery sleep induces analgesia via sleep ensembles of the zona incerta acting through distinct neural circuits in mice.

The study examined how recovery sleep in mice engages sleep-activated neuronal ensembles in the zona incerta (ZI) to produce analgesia, using optrode recordings and ensemble activation/inhibition. Sleep ensembles preferentially fired during NREM sleep, chronic pain attenuated their activity, and manipulating neurotensin (NTS)-expressing ZI neurons bidirectionally increased NREM sleep and reduced pain sensitivity, with NTS knockdown blunting these effects. These findings identify a defined NTS+ ZI circuit that links NREM sleep to analgesia and suggests a mechanistic target for sleep-based pain therapies.

An opioid efficacy switch for reversible optical control of analgesia.

The study created a reversibly photoswitchable morphinan agonist, azo-morphine-3 (AM-3), to control mu-opioid receptor (MOR) signaling with light and to define an “opioid efficacy switch” for analgesia. AM-3 interconverted between low- and high-efficacy MOR states depending on light exposure, and structural analyses of the trans (low efficacy) and cis (high efficacy) AM-3 bound to MOR revealed distinct binding modes. This enables reversible, spatially/temporally precise optical control of MOR efficacy, offering a route to separate therapeutic analgesia from side effects.

A pair of chitosan receptors confer broad-spectrum fungal resistance.

The study investigated how plants perceive the fungal cell-wall component chitosan, focusing on the rice apoplast-localized DUF26 protein OsFID1 and its plasma-membrane kinase partner OsFID2. OsFID1 formed a receptor complex with OsFID2, and OsFID2 phosphorylation was required for chitosan sensing and immune activation, with the OsFID1–OsFID2 complex conferring broad-spectrum resistance to fungal pathogens. This identifies a conserved plant chitosan receptor pair (OsFID1/OsFID2) that could be leveraged to engineer durable, broad-spectrum fungal disease resistance.

This study examined sexual dimorphism in epidermal stem cell dynamics by using intravital time-lapse imaging to track lineage-labeled cell fate in living tissue. It characterized differences in how epidermal stem/progenitor populations behave and differentiate between sexes during homeostasis. The findings advance understanding of sex-specific skin biology and may inform tailored approaches to regenerative medicine and dermatologic disease.

Emerging therapies for knee osteoarthritis.

This review summarized emerging therapies for knee osteoarthritis, focusing on the heterogeneity of whole-joint disease mechanisms and the evolving therapeutic pipeline. It highlighted that current symptomatic treatments have modest efficacy and that disease-modifying drug development has been challenging, while newer strategies—including incretin-based therapies such as semaglutide—are being explored. The synthesis helps clinicians and researchers prioritize mechanistically informed interventions for a complex, multifactorial condition.

Second-line dupilumab after anti-IL5/Rα failure: remission rates and clinical outcomes in severe asthma.

This observational cohort study assessed remission at 12 months after switching severe asthma patients in Denmark from second-line anti–IL-5/IL-5Rα therapy to anti–IL-4/IL-13 therapy, using four remission domains (no exacerbations, no maintenance oral corticosteroids, ACQ-6 ≤1.5, and FEV1 >80% predicted). Among 173 adults (median age 55), the study quantified remission rates and associated clinical outcomes after anti–IL-5/IL-5Rα failure (full results truncated in the abstract). These findings are significant for guiding biologic sequencing in severe asthma when first-line anti–IL-5/IL-5Rα does not achieve remission.

Reframing traumatic brain injury and spinal cord injury as chronic multisystem disorders: toward integrated, long-term care.

This perspective article argues that traumatic brain injury (TBI) and spinal cord injury (SCI) should be reframed as acute-onset multisystem chronic-risk conditions requiring integrated, long-term care rather than time-limited treatment. It highlights that fragmented surveillance contributes to preventable mortality and avoidable readmissions and proposes reclassification to better align cardiovascular, endocrine, and psychiatric services with neurotrauma-specific risks (specific program proposals are truncated in the abstract). The significance is a systems-level shift toward durable follow-up models to reduce long-term complications after TBI/SCI.

GLP-1 receptor agonist initiation and risk of psychiatric hospitalisation and emergency department presentation in adults with schizophrenia and type 2 diabetes in the USA: an observational cohort study using electronic health records data.

This observational cohort study used US electronic health records to examine whether initiating GLP-1 receptor agonists is associated with psychiatric hospitalisation and emergency department presentations in adults with schizophrenia and type 2 diabetes, compared with DPP-4 inhibitor initiation, SGLT2 inhibitor initiation, and non-initiation. The study design targets potential psychiatric benefit alongside metabolic effects, but the abstract truncates the reported effect estimates. If GLP-1 initiation shows differential psychiatric risk, it would be clinically important for selecting glucose-lowering therapies in patients with schizophrenia and diabetes.

A pseudoenzyme sensor of trehalose-6-phosphate directly represses the metabolic integrator SnRK1 in plants.

This work investigated how trehalose-6-phosphate (T6P) sensing regulates plant metabolism by identifying the noncatalytic Class-II T6P synthase (TPS-II) as a T6P sensor in Arabidopsis. T6P binding to TPS-II triggers conformational changes that enable TPS-II to interact with and repress the kinase activity of SNF1-related protein kinase 1 (SnRK1), and loss of TPS-II disrupts this repression. The study clarifies a direct T6P-to-SnRK1 signaling mechanism that links sugar availability to plant growth and carbon utilization.

An NAD+-responsive adipose signal coordinates inter-organ defense against muscle atrophy.

This study examined how NAD+ supplementation protects against skeletal muscle atrophy by identifying an adipose-derived signal in aging, disuse, and cancer cachexia models. NAD+ in adipose tissue activated STAT1-dependent transcription of the adipokine Serpina3n, which was released systemically and preserved muscle metabolic and protein homeostasis. The NAD+-STAT1–Serpina3n axis suggests a therapeutic route to prevent or treat muscle wasting.

Effects of adjunctive metformin on recurrence-free survival and reproductive outcomes following progestin-based fertility-sparing treatment for endometrial neoplasia: Results from the FELICIA trial, a prospective, randomized, phase IIb trial with blinded central adjudication.

The FELICIA phase IIb randomized trial evaluated whether adjunctive metformin improves recurrence-free survival and reproductive outcomes in women aged 18–42 with atypical endometrial hyperplasia or presumed stage IA grade 1 endometrioid carcinoma treated with fertility-sparing progestin therapy. Participants were assigned to medroxyprogesterone acetate (MPA) alone versus MPA plus metformin 750 mg/day or 1500 mg/day, with central blinded pathological adjudication. The clinical significance lies in determining whether metformin can enhance outcomes of fertility-sparing treatment in endometrial neoplasia without compromising reproductive goals.

Adult Attention Deficit-Hyperactivity Disorder.

This narrative review summarized the epidemiology, clinical presentation, comorbidities, and diagnostic challenges of adult attention-deficit/hyperactivity disorder (ADHD) across the lifespan. The key finding is that adult ADHD is frequently underrecognized and often coexists with psychiatric and somatic conditions, including increased risk for cardiovascular and metabolic diseases. Clinically, this supports broader screening and integrated management strategies for adults with ADHD who present to care for both mental health and medical comorbidities.

Long-Acting HIV Therapy in African Adults with Adherence Challenges.

In a phase 3b open-label randomized trial in eastern and southern Africa, adults with virally suppressed HIV-1 but suboptimal adherence or care engagement were assigned to long-acting injectable cabotegravir plus rilpivirine every 8 weeks versus continued oral dolutegravir-based therapy. The key finding was that long-acting cabotegravir/rilpivirine provides an adherence-challenged strategy to maintain viral suppression compared with oral therapy. This is clinically significant because it offers a practical treatment approach to reduce virologic failure in populations where daily oral adherence is difficult.
