J Immunol. 2026 Aug 29;215(9):vkag247. doi: 10.1093/jimmun/vkag247. ABSTRACT SWI/SNF chromatin remodeling complexes regulate gene expression during development and differentiation. These complexes exist in distinct forms, including the polybromo-associated BAF (PBAF) complex, defined by the ARID2 subunit. ARID2 is frequently mutated in B cell leukemias, but its role in normal B cell development remains unknown. Using … Read more

J Immunol. 2026 Aug 29;215(9):vkag179. doi: 10.1093/jimmun/vkag179. ABSTRACT Psoriasis is a chronic inflammatory skin disease involving intricate neuroimmune crosstalk. However, the specific mechanisms and therapeutic targets remain elusive. In this study, a pilot clinical trial demonstrated that intravenous scopolamine, a muscarinic receptor antagonist, significantly ameliorated skin lesions in psoriasis patients. Consistently, scopolamine reduced inflammation in … Read more

J Immunol. 2026 Aug 29;215(9):vkag233. doi: 10.1093/jimmun/vkag233. ABSTRACT Psoriasis is a chronic, immune-mediated inflammatory skin disease affecting at least 2% of the global population. Papaverine, an alkaloid with known anti-inflammatory, anti-cancer, and RAGE-antagonistic properties, has not been previously evaluated for anti-psoriatic activity. This study investigated the protective effects and mechanisms of papaverine in an imiquimod … Read more

J Immunol. 2026 Aug 29;215(9):vkag241. doi: 10.1093/jimmun/vkag241. ABSTRACT The role of selenium in tumor progression remains controversial, and its mechanisms of action in the context of immunotherapy are poorly understood. In this study, our findings indicate that selenium supplementation did not alter immune parameters, induce organ damage under healthy conditions, or affect the growth of … Read more

J Immunol. 2026 Aug 29;215(9):vkag244. doi: 10.1093/jimmun/vkag244. ABSTRACT The increasing demand for nuclear power and radiotherapy has expanded potential avenues for human exposure to whole-body irradiation (WBI), underscoring the need to understand its impact on immune cells. While prior studies have explored radiation-induced disruptions in immune homeostasis, the direct effect of WBI on pre-existing memory … Read more

J Immunol. 2026 Aug 29;215(9):vkag238. doi: 10.1093/jimmun/vkag238. ABSTRACT Many autoimmune diseases exhibit a female sex bias in prevalence and severity, yet the mechanisms for this remain unclear. 17β-estradiol (E2) is a steroid sex hormone with established immunomodulatory roles in CD4+ T cells, which express the nuclear estrogen receptors ERα and ERβ. Autoimmune disease patients exhibit … Read more

J Immunol. 2026 Aug 29;215(9):vkag224. doi: 10.1093/jimmun/vkag224. ABSTRACT Hepatic ischemia-reperfusion (I/R) injury triggers release of small extracellular vesicles (sEVs) that can function as systemic conveyors of inflammatory signals. While sEV-mediated immune cell modulation has been studied extensively in vitro, knowledge is based largely on sEVs derived from cultured cells, rather than injured tissues. Consequently, the … Read more

J Immunol. 2026 Aug 29;215(9):vkag178. doi: 10.1093/jimmun/vkag178. ABSTRACT Neutrophils have been implicated in mediating immune crosstalk between injured tissue and distal organs, either promoting local and distal inflammation or mediating tissue repair. Skin injury from ultraviolet (UV) light triggers neutrophil migration to the kidney, which may have implications for nephritis flares in systemic lupus erythematosus. … Read more

J Immunol. 2026 Aug 29;215(9):vkag237. doi: 10.1093/jimmun/vkag237. ABSTRACT Through screening of a VHH phage display library constructed from an alpaca immunized with the recombinantly expressed murine myelin oligodendrocyte (MOG)-specific 2D2 T cell receptor (TCR), we identified nanobodies that reduced antigen-driven 2D2 T cell activation in vitro. Immunoblotting and staining confirmed TCRβ chain reactivity and Vβ11-associated … Read more

J Immunol. 2026 Aug 4;215(8):vkag199. doi: 10.1093/jimmun/vkag199. ABSTRACT Invariant natural killer T (iNKT) cells are unconventional ɑβ T cells that respond to lipid-based antigens. They play a vital role in response to infections and are involved in diseases such as allergic asthma and cancer. Despite clear immunological roles across multiple diseases, remarkably few tools exist … Read more
