J Immunol. 2026 Feb 9;215(2):vkaf370. doi: 10.1093/jimmun/vkaf370. ABSTRACT This study aimed to investigate the role of CD29 and CD99 in human T lymphocytes and elucidate its significance in Sjögren’s disease (SjD). ScRNA-Seq data were utilized to analyze CD29 and CD99 expression in PBMCs. CD29 and CD99-expressing T lymphocyte proportions in SjD patients and healthy controls … Read more

J Immunol. 2026 Feb 9;215(2):vkaf381. doi: 10.1093/jimmun/vkaf381. ABSTRACT Type 1 diabetes (T1D) is an autoimmune disease in which T cells mediate the elimination of the insulin-producing beta cells in the pancreatic islets, resulting in the need for exogenous insulin. Studies of T1D in both patients and the nonobese diabetic (NOD) mouse model of the disease … Read more

J Immunol. 2026 Feb 9;215(2):vkaf327. doi: 10.1093/jimmun/vkaf327. ABSTRACT Glioblastoma (GBM) remains the most lethal intracranial malignancy in the central nervous system with limited therapeutic options. Laser interstitial thermal therapy (LITT) has emerged as a novel minimally invasive treatment for GBM. Around the core ablation zone of LITT, there exists a sublethal ablation zone caused by … Read more

J Immunol. 2026 Feb 9;215(2):vkaf350. doi: 10.1093/jimmun/vkaf350. ABSTRACT Co-expression of 2 T cell receptor (TCR) clonotypes due to allelic inclusion occurs in ∼16% of peripheral blood T cells in mice and humans. Evidence indicates dual TCR expression can affect thymic development and peripheral function. Notably, dual TCR cells demonstrate increased reactivity against self-antigens and heightened … Read more

J Immunol. 2026 Feb 9;215(2):vkaf346. doi: 10.1093/jimmun/vkaf346. ABSTRACT MR1 is an major histocompatibility complex class I-like molecule that presents small molecule metabolites to MR1-restricted T cells that include a major population of highly conserved T cells known as mucosal-associated invariant T (MAIT) cells. MAIT cells recognize bacterial riboflavin pathway-derived neoantigens and are being attributed an … Read more

J Immunol. 2026 Feb 9;215(2):vkaf367. doi: 10.1093/jimmun/vkaf367. ABSTRACT Dickkopf1 (DKK1) is a quintessential Wnt antagonist and immunomodulator in various inflammatory diseases. The underlying molecular mechanisms of DKK1-mediated immunomodulation remain elusive. Here, we identified TLR4 as a new receptor for DKK1, activating NFκB-mediated gene expression. Subsequently, this event resulted in pyroptosis via the NLRP3 inflammasome in … Read more

J Immunol. 2026 Feb 9;215(2):vkaf359. doi: 10.1093/jimmun/vkaf359. ABSTRACT Membrane atg8ylation is a broad homeostatic process of immunological import. It encompasses membrane repair and remodeling pathways, including canonical autophagy, in cells subjected to stress, damage, infection, and immune or metabolic signaling under microbe-induced or sterile inflammatory conditions. The initial reports on autophagy, which is one of … Read more

J Immunol. 2026 Feb 9;215(2):vkaf331. doi: 10.1093/jimmun/vkaf331. ABSTRACT Exposure to a diversity of microbes has been implicated in playing a major role in susceptibility to the development of allergic lung-type diseases. The hygiene hypothesis suggests that those exposed to a broad diversity of microbes are more likely to be protected against developing allergic-type diseases. However, … Read more

J Immunol. 2026 Feb 9;215(2):vkaf341. doi: 10.1093/jimmun/vkaf341. ABSTRACT Preterm birth is the leading cause of neonatal morbidity and mortality. Management of preterm labor relies on the use of tocolytics, like nifedipine, which fail to prevent preterm birth and related morbidities. Interleukin-1β plays significant roles in the pathophysiology of preterm birth including inflammation and uterine activation. … Read more

J Immunol. 2026 Feb 9;215(2):vkaf362. doi: 10.1093/jimmun/vkaf362. ABSTRACT Environmental temperature significantly influences immune responses. Cold exposure suppresses host defense against infections and exacerbates autoimmune and allergic conditions. However, the molecular mechanisms underlying temperature-dependent immune regulation remain unclear. In this study, we evaluated the cold-activated sympathetic modulation of immune responses. We presented that semaphorin 6D (Sema6D), … Read more
