B Lymphocytes Impede Tregs To Erode Islet Tolerance In Type 1 Diabetes, Christopher S Wilson, Blair T Stocks, Alexander C Falk, Daniel J Moore

Faculty, Staff and Students Publications

B lymphocytes are thought to drive β-cell destruction in type 1 diabetes (T1D) by activating anti-islet T cells. However, the observation that autoreactive T-cell activation and disease progression can occur without B cells challenges this view. Still, preclinical and clinical studies have shown that B-cell depletion alleviates β-cell destruction, suggesting a critical role for B cells in T1D. Our findings propose an alternative function for B cells, impairing regulatory T cells (Tregs) that would otherwise protect islets. In the NOD islet transplant model, we show that B-cell absence enables transplant tolerance, allowing Tregs to become responsive to immune therapy and …

Frontiers In Ocean Non-Equilibrium Dynamics And Challenges In Operational Oceanography Application, Yuhong Zhang, Yan Du, Tianyu Wang, Minyang Wang, Qin Duan, Xinlong Li, Yuhang Zheng, Yifan Xia, Shilin Tang, Yineng Li, Jianping Yin

Bulletin of Chinese Academy of Sciences (Chinese Version)

Ocean circulation exhibits complex multiscale dynamics, among which non-equilibrium processes, marked by transient behavior, strong perturbations, and pronounced nonlinearity, are of particular importance for maritime environmental support. However, limited observational capability has long constrained the study of subsurface non-equilibrium dynamics, leaving numerical models insufficiently validated and positioning this issue at the forefront of modern physical oceanography. Artificial intelligence (AI) offers a promising pathway to overcome this bottleneck. Built on this concept, the “iEddy” AI large ocean model can efficiently reconstruct high-resolution, high-accuracy three-dimensional temperature, salinity, and velocity from sea-surface remote sensing data, demonstrating strong capability in capturing non-equilibrium ocean currents …

Multiple myeloma (MM) is consistently preceded by monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM). While these precursor conditions are asymptomatic, they are not entirely benign and carry a lifelong risk of progression to MM. Unlike other cancers defined by pathology, malignant transformation from MGUS or SMM to MM has so far relied on demonstration of clinical end-organ damage as morphology and cytogenetics cannot reliably distinguish them. In this study, using genomic data from 374 patients with MGUS or SMM (277 training, 97 validation), to our knowledge, we demonstrate for the first time the ability to identify …

Ionic Mechanisms Of Two-Pore Channel Regulation Of Vesicle Trafficking, Heng Zhang, Michael X Zhu

Faculty, Staff and Student Publications

The endolysosomal system plays a pivotal role in cellular function. Before reaching lysosomes for degradation, the endocytosed cargoes are sorted at various stages of endosomal trafficking for recycling and/or rerouting. The proper execution of these processes depends on tightly regulated ion fluxes across endolysosomal membranes. Recent studies have demonstrated the importance of two-pore channels (TPCs), including TPC1 and TPC2, in endolysosomal trafficking. These channels are expressed in the membranes of distinct populations of endosomes and lysosomes, where they respond to nicotinic acid adenine dinucleotide phosphate (NAADP) and phosphatidylinositol 3,5-bisphosphate [PI(3,5)P2] to conduct Ca2+ and Na+ release from these acidic organelles. …

Simulated Complex Cells Contribute To Object Recognition Through Representational Untangling, Mitchell B Slapik, Harel Z Shouval

Faculty, Staff and Student Publications

The visual system performs a remarkable feat: it takes complex retinal activation patterns and decodes them for object recognition. This operation, termed "representational untangling," organizes neural representations by clustering similar objects together while separating different categories of objects. While representational untangling is usually associated with higher-order visual areas like the inferior temporal cortex, it remains unclear how the early visual system contributes to this process-whether through highly selective neurons or high-dimensional population codes. This article investigates how a computational model of early vision contributes to representational untangling. Using a computational visual hierarchy and two different data sets consisting of numerals …

Journal of Community Hospital Internal Medicine Perspectives

Inflammatory bowel disease (IBD), encompassing Crohn’s disease and ulcerative colitis, is a chronic immune-mediated condition requiring long-term management. Traditional immunosuppressants, such as corticosteroids, thiopurines, and methotrexate, have been widely used but are associated with broad immunosuppressive effects and significant adverse events. The advent of biological therapies, including tumor necrosis factor (TNF) inhibitors, integrin inhibitors, and interleukin (IL)-12/23 inhibitors, has revolutionized IBD treatment by offering targeted immune modulation. Biologics have demonstrated superior efficacy in achieving and maintaining remission compared to traditional immunosuppressants, particularly in moderate to severe IBD. They provide targeted immune suppression, reducing systemic side effects, but are associated with …

Statin Induced New-Onset Diabetes Mellitus A Narrative Review, Jasvin K Manha, Sumanth Kumar Bandaru

Journal of Community Hospital Internal Medicine Perspectives

Statins are widely used to lower LDL cholesterol and prevent cardiovascular disease. Although generally safe, there is increasing evidence that they may increase the risk of new-onset diabetes mellitus (NODM). Recent studies show a modest but consistent rise in diabetes risk associated with statin use, especially among individuals with prediabetes, obesity, or other metabolic risk factors. High-intensity statins like atorvastatin and rosuvastatin carry a greater risk compared to agents such as pravastatin or pitavastatin. Proposed mechanisms include increased insulin resistance, impaired insulin secretion, and changes in hepatic glucose production. Despite the diabetes risk associated with statins, their well-established cardiovascular benefits …
