Abstract
Stress-induced epithelial plasticity is central to lung regeneration, fibrosis, and malignancy, but how cellular stress leads to differentiation is incompletely understood. Here, we found a central role for IRE1α, a conserved mediator of the unfolded protein response (UPR), in stimulating the plasticity of alveolar type 2 (AT2) cells. In single-cell RNA-seq, IRE1α activity was associated with loss of AT2 identity and progression toward a damage-associated transitional state unique to fibrosis. AT2 plasticity required destructive regulated IRE1α-dependent decay (RIDD), which we demonstrated by deploying PAIR2, a kinase modulator that inhibits RIDD while preserving IRE1α’s adaptive XBP1 mRNA splicing activity. In vivo, selective inhibition of RIDD with PAIR2 reduced AT2 differentiation into profibrotic transitional cells and protected mice from bleomycin-induced pulmonary fibrosis. Mechanistically, we identified the Fgfr2 mRNA as a direct and regulated substrate for IRE1α’s RNase in primary AT2 cells and in a biochemically reconstituted cell-free system. Loss of Fgf signaling caused AT2 differentiation, while gain of signaling protected cells from IRE1α-induced differentiation. We propose that IRE1α downregulates Fgf signaling through RIDD, provoking loss of AT2 identity and differentiation towards a profibrotic phenotype. Thus, IRE1α’s RIDD activity emerges as a novel target for treatment of pulmonary fibrosis and potentially other diseases driven by aberrant epithelial cell plasticity.

Abstract
Diabetic peripheral neuropathy (DPN) is a prevalent complication of diabetes mellitus caused by metabolic toxicity to peripheral axons. We aimed to gain deep mechanistic insight into the disease using transcriptomics on tibial and sural nerves recovered from lower leg amputations in a mostly diabetic population and control sural nerves from cross-facial nerve graft surgery. First, comparing DPN versus control sural nerves revealed inflammatory activation and sensory changes in DPN. Second, when comparing mixed sensory and motor tibial and purely sensory sural nerves, we identified key pathway differences in affected DPN nerves, with distinct immunological features observed in sural nerves. Third, spatial transcriptomics of sural nerves revealed shifts in immune cell types associated with axonal loss progression. We also found clear evidence of neuronal transcript changes, like PRPH, in nerves with axonal loss, suggesting perturbed RNA transport into distal sensory axons. This motivated further investigation into neuronal mRNA localization in peripheral nerve axons, generating evidence of robust localization of mRNAs such as SCN9A and TRPV1 in human sensory axons. Our work provides insight into altered cellular and transcriptomic profiles in human nerves in DPN and highlights sensory axon mRNA transport as a potential contributor to nerve degeneration.

Abstract
Mechanisms responsible for delayed wound repair are poorly understood despite the common impact of this disorder on health. To study how Staphylococcus aureus disrupts healing, mouse and human wound repair models were evaluated after exposure to S. aureus or commensal Staphylococcus. Quorum sensing by S. aureus, but not S. hominis, delayed repair and inhibited the expression of genes responsible for lipid metabolism in keratinocytes. S. aureus with inactive accessory gene regulator (agr) did not delay healing, and the inhibition of lipid metabolism was recapitulated in vitro by synthetic phenol soluble modulin α1 (psmα1) and psmα4, genes that are under agr control. However, S. aureus strains with single deletion of psmA, psmB, alpha-hemolysin (hla), or hld gene continued to delay repair, suggesting that S. aureus used multiple agr-dependent virulence factors to disrupt healing. These observations provide insight into mechanisms for delayed wound healing, identify quorum sensing as a critical event, and highlight the role of lipid biosynthesis in wound reepithelialization.

Abstract
Despite the potential of targeted epigenetic therapies, most cancers do not respond to current epigenetic drugs. The polycomb repressive complex EZH2 inhibitor tazemetostat was recently approved for the treatment of SMARCB1-deficient epithelioid sarcomas, based on the functional antagonism between PRC2 and SMARCB1. Through the analysis of tumors of patients treated with tazemetostat, we recently defined key principles of their response and resistance to EZH2 epigenetic therapy. Here, using transcriptomic inference from SMARCB1-deficient tumor cells, we nominate the DNA damage repair kinase ATR as a target for rational EZH2 combination epigenetic therapy. We showed that EZH2 inhibition promotes DNA damage in epithelioid and rhabdoid tumor cells, at least in part via its induction of piggyBac transposable element derived 5 (PGBD5). We leveraged this collateral synthetic lethal dependency to target PGBD5-dependent DNA damage by inhibition of ATR, but not CHK1, using the ATR inhibitor elimusertib. Consequently, combined EZH2 and ATR inhibition improved therapeutic responses in diverse patient-derived epithelioid and rhabdoid tumors in vivo. This advances a combination epigenetic therapy based on EZH2-PGBD5 synthetic lethal dependency suitable for immediate translation to clinical trials for patients.

Abstract
Dysfunction of striatal medium spiny neurons (MSNs) is implicated in several neurological disorders, including Huntington’s disease (HD). Despite progress in characterizing MSN pathology in HD, mechanisms underlying MSN susceptibility remain unknown, driving the need for MSNs derived from human pluripotent stem cells (hPSCs), especially subtypes in research and therapy. Here, we established a scalable 3D-default culture system to produce striatal MSNs efficiently from hPSCs by activation of the endogenous sonic hedgehog (SHH) pathway. These cells expressed canonical markers of striatal progenitors and dopamine D1 (D1) and dopamine D2 (D2) MSNs and presented dynamic specification and transcriptional signatures that closely resemble endogenous MSNs at single-cell resolution, both in vitro and post-transplantation in HD mice with quinolinic acid (QA) lesions. Grafted human cells survived and matured into D1-/D2-like MSNs and projected axons to endogenous targets including globus pallidus externus, globus pallidus internus, and substantia nigra pars reticulata to reconstruct the basal ganglia pathways. Functionally, they displayed spontaneous synaptic currents, received regulation from host cortex and thalamus, and were modulated by dopamine to either enhance or reduce neuronal excitability, similar to the endogenous D1-/D2-MSNs, subsequently improving behavior in QA-lesioned HD mice. Our study presents a method for generating authentic MSNs, providing a reliable cell source for HD cell therapy, mechanistic studies, and drug screening.

Abstract
Crypt hyperplasia is a key feature of celiac disease (CeD) and several other small intestinal inflammatory conditions. Analysis of the gut epithelial crypt zone by mass spectrometry–based tissue proteomics revealed a strong IFN-γ signal in active CeD. This signal, hallmarked by increased expression of MHC molecules, was paralleled by diminished expression of proteins associated with fatty acid metabolism. Crypt hyperplasia and the same proteomic changes were observed in WT mice administered IFN-γ. In mice with conditional KO of the IFN-γ receptor in gut epithelial cells, these signature morphological and proteomic changes were not induced with IFN-γ administration. IFN-γ was thus a driver of crypt hyperplasia in CeD by acting directly on crypt epithelial cells. The results are relevant to other enteropathies with involvement of IFN-γ.

Abstract
Hypoxia in the tumor microenvironment promotes lymphatic metastasis, yet the role of cancer-associated fibroblasts (CAFs) in this process remains insufficiently elucidated in colorectal cancer (CRC). In this study, we developed a large language model–based cellular hypoxia–predicting classifier to identify hypoxic CAFs (HCAFs) at single-cell resolution. Our findings revealed that HCAFs enhance CRC lymphatic metastasis by secreting CLEC11A, a protein that binds to the LGR5 receptor on tumor cells, subsequently activating the WNT/β-catenin signaling pathway. This promotes epithelial-mesenchymal transition and lymphangiogenesis, facilitating the spread of tumor cells via the lymphatic system. Furthermore, we demonstrate that the hypoxia-induced transcription factor HIF1A regulates the conversion of normoxic CAFs to HCAFs, driving CLEC11A expression and promoting metastasis. In vivo and vitro experiments confirmed the pro-metastatic role of CLEC11A in CRC, with its inhibition reducing lymphatic metastasis. This effect was markedly reversed by targeting the LGR5 receptor on tumor cells or inhibiting the WNT/β-catenin pathway, further elucidating the underlying mechanisms of CLEC11A-driven metastasis. These findings underscore the potential of targeting the CLEC11A-LGR5 axis to prevent lymphatic dissemination in CRC. Our study highlights the role of HCAFs in CRC progression and reveals mechanisms of lymphatic metastasis for intervention.

Abstract
Protein arginine methyltransferase 5 (PRMT5) complexes with methylosome protein 50 (MEP50) play crucial roles in tumor progress. However, the regulatory mechanism of governing the PRMT5-MEP50 hetero-octameric complex remains unclear. Here, we demonstrate that C6orf223, to our knowledge an uncharacterized protein, facilitates PRMT5-MEP50 multiprotein complex assembling, thereby promoting colorectal cancer (CRC) growth and metastasis. C6orf223 forms dimers through disulfide bonds, with its N-terminal arginine-enriched region binding to the C-terminal negatively charged groove of PRMT5, thus stabilizing PRMT5-MEP50 multiprotein and enhancing PRMT5 methyltransferase activity. Consequently, PRMT5-mediated H4R3me2s substantially decreases the expression of the tumor suppressor GATA5, leading to the upregulation of multiple oncogenic target genes including WWTR1, FGFR1, and CLU. Targeting C6orf223 using siRNAs encapsulated in ferritin protein shells effectively suppresses CRC tumor growth and metastasis. Collectively, our findings characterize the role of C6orf223 in facilitating PRMT5-MEP50 hetero-octameric complex assembling and suggest that C6orf223 could serve as a potential therapeutic target for CRC.

Abstract
Genome editing has the potential to treat genetic hearing loss. However, current editing therapies for genetic hearing loss have shown efficacy only in hearing rescue. In this study, we evaluated a rescue strategy using adeno-associated virus (AAV) type 2–mediated delivery of Staphylococcus aureus Cas9-sgRNA in the mature inner ear of the P2rx2V61L/+ mouse model of autosomal dominant deafness-41 (DFNA41), a dominant, delayed-onset, and progressive hearing loss in humans. We demonstrate that local injection in adult mice results in efficient and specific editing that abolishes the mutation without notable off-target effects or AAV genome integration. Editing effectively restores long-term auditory and vestibular function. Editing further protects P2rx2V61L/+ mice from hypersensitivity to noise-induced hearing loss, a phenotype also observed in patients with DFNA41. Intervention in mice at a juvenile stage broadens the frequency range rescued, highlighting the importance of early intervention. An effective and specific gRNA for the human P2RX2 V60L mutation has been identified. Our study establishes the feasibility of editing to treat DFNA41 caused by P2RX2 V60L mutation in humans and opens an avenue for using editing to rescue hearing and vestibular function while mitigating noise-induced hearing loss.

Abstract
Sympathetic tone is a central signaling axis inhibiting osteogenesis; however, the combination of durable local and systemic sympathetic effects on bone argues that multiple mechanisms, including yet-undiscovered pathways, are involved. Here, we found that sympathetic nerves constituted a component of the skeletal stem cell (SSC) niche: mice with conditional deletion of the classical axonal repellent Slit2 in sympathetic nerves (Slit2th mice), but not in bone stem/progenitor cells or sensory nerves, showed osteopenia due to an increase in sympathetic innervation and an associated decrease in SSCs. Mice with increased skeletal sympathetic innervation displayed impaired SSC niche function in an SSC orthotopic transplantation and engraftment system. Follistatin-like 1 (FSTL1) is a SLIT2-regulated soluble factor suppressing SSC self-renewal and osteogenic capacity. Accordingly, ablation of Fstl1 in sympathetic neurons enhanced SSC-driven osteogenesis and attenuated the bone loss seen in Slit2th mice. Together, the findings indicate that SLIT2 is a regulator of a sympathetic nerve–mediated SSC niche.

Abstract
Therapies based on glucagon-like peptide-1 (GLP-1) reduce rates of cardiovascular and chronic kidney disease in people with type 2 diabetes and/or obesity, with ongoing clinical trials investigating their effects in people with metabolic liver disease, arthritis, and both substance use and neurodegenerative disorders. Acute and chronic activation of GLP-1 receptor signaling also reduces systemic and tissue inflammation in mice and humans, through weight loss–dependent and –independent mechanisms, actions that may contribute to the expanding spectrum of clinical benefits ascribed to GLP-1 medicines. In this Review, we highlight current understanding of the direct and indirect antiinflammatory effects and mechanisms of GLP-1 medicines in both preclinical and clinical studies, covering emerging concepts, clinical relevance, and areas of uncertainty that require further investigation.

Abstract
The increasing recognition of a new category of encephalitides that occur in association with antibodies against neuronal surface proteins has prompted the use of terms like “autoimmune psychosis” and “autoimmune psychiatric disorders.” However, although psychosis and other psychiatric symptoms can occur in autoimmune encephalitides and systemic autoimmune diseases, evidence for a distinct psychiatric entity beyond these conditions is lacking. A particularly defining condition is anti-NMDA receptor encephalitis, which has been central to promoting concepts such as autoimmune psychosis and autoimmune psychiatric disorders. While anti-NMDA receptor encephalitis can resemble primary psychiatric conditions, certain clinical features often suggest the specific diagnosis. This Review traces the development of the autoimmune psychosis concept and examines the implications of framing it as a separate entity. We discuss leading theories of psychosis and the convergence of the NMDA receptor hypofunction/glutamate hypothesis with anti-NMDA receptor encephalitis mechanisms. The interest generated by such disorders has driven uncontrolled antibody testing in psychiatric populations, often neglecting pretest probability and favoring prevalence over diagnostic specificity. Finally, we highlight the main limitations of current approaches and propose directions for future research.

Abstract
Cancer diagnoses are prevalent in people with obesity and type 2 diabetes, and abundant clinical evidence supports the protective effects of weight loss for cancer prevention. Glucagon-like peptide-1 (GLP-1) receptor agonists have revolutionized obesity and type 2 diabetes medicine and alleviate many comorbidities of these metabolic diseases. In this Review, we summarize the current clinical evidence for GLP-1 receptor agonists and cancer risk, including thyroid, pancreatic, gastrointestinal, and hormone-dependent malignancies. With few exceptions, recent meta-analyses report that GLP-1 receptor therapies do not increase cancer incidence and may lower risk in some cases. Preclinical studies reinforce the anticancer effects of GLP-1 receptor therapies, even in non-obese models. However, there are still many opportunities for translational insight as the field grows. Immune-modulating effects of GLP-1 receptor agonists are reported in several preclinical cancer studies, which may reflect direct action on immune cells or result from improved metabolic function. We highlight ongoing clinical trials for GLP-1 receptor therapies in cancer patients, and offer considerations for preclinical studies, including perspectives on the timing and duration of GLP-1 receptor agonist treatment, concurrent use of standard anticancer therapies, and interpretation of models of cancer risk versus progression.

Abstract
Pancreatic cancer (PC) is a devastating disease, due in part to its diagnosis frequently being made at an advanced stage. Ongoing efforts are aimed at identifying early-stage PC in high-risk individuals, as early detection leads to downstaging of PC and improvements in survival. However, there are a myriad of challenges that arise when trying to optimize PC early detection strategies, including selection of the appropriate high-risk individuals and selection of the test or combination of tests that should be performed. Here, we discuss the populations that are the strongest candidates for PC screening and review professional PC screening guidelines. We also summarize the current state of imaging techniques for early detection of PC and further review many studied biomarkers — ranging from nucleic acid targets, proteins, and the microbiome — to highlight the current state of the field and the challenges that remain in the years to come.

Abstract
Stress has long been associated with substance misuse and substance use disorders (SUDs). The past two decades have seen a surge in research aimed at understanding the underlying mechanisms driving this association. This Review introduces a multilevel “adaptive stress response” framework, encompassing a stress baseline, acute reaction, and recovery with return-to-homeostasis phase that occurs at varying response times and across domains of analysis. It also discusses evidence showing the disruption of this adaptive stress response in the context of chronic and repeated stressors, trauma, adverse social and drug-related environments, as well as with acute and chronic drug misuse and with drug withdrawal and abstinence sequelae. Subjective, cognitive, peripheral, and neurobiological disruptions in the adaptive stress response phases and their link to inflexible, maladaptive coping; increased craving; relapse risk; and maintenance of drug intake are also presented. Finally, the prevention and treatment implications of targeting this “stress pathophysiology of addiction” are discussed, along with specific aspects that may be targeted in intervention development to rescue stress-related alterations in drug motivation and to improve SUD treatment outcomes.

Abstract
Peptidyl arginine deiminases (PADs) catalyze the conversion of arginine residues into peptidyl citrulline, a posttranslational modification known as protein citrullination (or arginine deimination). This process alters the charge of proteins from positive to neutral, thereby affecting their folding, stability, conformation, and function. PAD2 and PAD4 can translocate into the nucleus and citrullinate both cytoplasmic and nuclear proteins. In this Review, we focus on PAD2- and PAD4-mediated citrullination in immune cell subsets within the tumor microenvironment. We discuss how citrullination regulates immune cell function and tumor immunity and explore the potential of targeting citrullination as a strategy for cancer immunotherapy.

Abstract
Glucagon-like peptide-1 (GLP-1) was initially considered to be a hormone with a predominant role in regulating glucose metabolism by inducing insulin secretion, reducing glucagon secretion, and ameliorating insulin resistance, with the last effect being largely dependent on the induction of weight loss. In more recent years, the role of this peptide beyond metabolism has progressively been explored, including its impact on kidney physiology and kidney clinical outcomes in people with obesity with or without diabetes. Indeed, despite only modest expression of the GLP-1 receptor in the kidney, the renoprotective actions of GLP-1 and its receptor agonists have become an area of intensive investigation. This Review appraises the current status of GLP-1 peptide and its receptor agonists and focuses on the preclinical as well as recent seminal clinical findings defining the kidney benefits conferred by GLP-1 receptor agonist treatment in people living with type 2 diabetes and obesity.

Abstract
Half of adults in the United States have hypertension as defined by clinical practice guidelines. Interestingly, women are generally more likely to be aware of their hypertension and have their blood pressure controlled with treatment compared with men, yet hypertension-related mortality is greater in women. This may reflect the fact that the female sex remains underrepresented in clinical and basic science studies investigating the effectiveness of therapies and the mechanisms controlling blood pressure. This Review provides an overview of the impact of the way hypertension research has explored sex as a biological variable (SABV). Emphasis is placed on epidemiological studies, hypertension clinical trials, the genetics of hypertension, sex differences in immunology and gut microbiota in hypertension, and the effect of sex on the central control of blood pressure. The goal is to offer historical perspective on SABV in hypertension, highlight recent studies that include SABV, and identify key gaps in SABV inclusion and questions that remain in the field. Through continued awareness campaigns and engagement/education at the level of funding agencies, individual investigators, and in the editorial peer review system, investigation of SABV in the field of hypertension research will ultimately lead to improved clinical outcomes.

Abstract
Bacteriophage (phage) therapy has emerged as a promising solution to combat the growing crisis of multidrug-resistant (MDR) infections. There are several international centers actively engaged in implementation of phage therapy, and recent case series have reported encouraging success rates in patients receiving personalized, compassionate phage therapy for difficult-to-treat infections. Nonetheless, substantial hurdles remain in the way of more widespread adoption and more consistent success. This Review offers a comprehensive overview of current phage therapy technologies and therapeutic approaches. We first delineate the common steps in phage therapy development, from phage bank establishment to clinical administration, and examine the spectrum of therapeutic approaches, from personalized to fixed phage cocktails. Using the framework of a conventional drug development pipeline, we then identify critical knowledge gaps in areas such as cocktail design, formulation, pharmacology, and clinical trial design. We conclude that, while phage therapy holds promise, a structured drug development pipeline and sustained government support are crucial for widespread adoption of phage therapy for MDR infections.

Abstract
Cannabis has been legalized for medical and recreational purposes in multiple countries. A large number of people are using cannabis and some will develop cannabis use disorder (CUD). There is a growing recognition that CUD requires specific interventions. This Review will cover this topic from a variety of perspectives, with a particular emphasis on neurobiological findings and innovative treatment approaches that are being pursued. We will first describe the epidemiology and burden of disease of CUD, including risk factors associated with CUD (both in terms of general risk and genetic risk variants). Neurobiological alterations identified in brain imaging studies will be presented. Several psychosocial interventions that are useful for the management of CUD, including motivational enhancement therapy, behavioral and cognitive therapy, and contingency management, will be covered. Although no pharmacological interventions are yet approved for CUD, we present the most promising pharmacological interventions being tested.
