ABSTRACT Major histocompatibility complex class Ia (MHC-Ia)-restricted CD8⁺ T cell responses play a central role in the host defense against HIV-1, with certain MHC-Ia alleles known to be associated with cytotoxic T lymphocyte responses having an increased potential for viral control. However, the impact of immune aging on … Read more
J Immunol. 2026 Oct 1;215(10):vkag257. doi: 10.1093/jimmun/vkag257. ABSTRACT Cryopyrin-associated periodic syndrome (CAPS) is an autoinflammatory disease caused by gain-of-function mutations in human nucleotide-binding domain, leucine-rich repeat-containing protein 3 (NLRP3), which lead to constitutive inflammasome activation and excessive IL-1β secretion. Long-term IL-1 blockade has markedly improved patient outcomes by preventing systemic inflammation and amyloidosis. However, whether … Read more
J Immunol. 2026 Oct 1;215(10):vkag269. doi: 10.1093/jimmun/vkag269. ABSTRACT CD8+ tissue-resident memory T cells (TRM) in the upper respiratory tract (URT) limit viral replication after transmission and prevent spread to the lower respiratory tract (LRT), whereas LRT CD8+ TRM are important for limiting immunopathology in the lung and promoting efficient viral clearance. Although the presence of … Read more
J Immunol. 2026 Oct 1;215(10):vkag276. doi: 10.1093/jimmun/vkag276. ABSTRACT CTLA-4 is an inhibitory receptor on T cells that limits immune activation by competing with the co-stimulatory receptor CD28 for binding to CD80 and CD86 on antigen-presenting cells. Regulatory T cells (Tregs) employ CTLA-4-mediated transendocytosis as a key suppressive mechanism. Several CTLA4 polymorphisms are associated with autoimmune … Read more
J Immunol. 2026 Oct 1;215(10):vkag270. doi: 10.1093/jimmun/vkag270. ABSTRACT HLA-A*02:01-restricted PB1413+CD8+ T cells provide the broadest reported cross-reactive immunity against influenza A, B, and C viruses. Here, we investigated T cell receptor (TCR) clonotypic signatures within these universal A2/PB1413+CD8+ T cell pools, compared with immunodominant influenza A-specific M158+CD8+ T cells and codominant influenza B-specific A2/HA543+CD8+ memory … Read more
J Immunol. 2026 Oct 1;215(10):vkag268. doi: 10.1093/jimmun/vkag268. ABSTRACT Multiple sclerosis (MS) is thought to be mediated by human leukocyte antigen (HLA) class II-restricted autoreactive CD4 T cells producing interleukin (IL)-17A and/or interferon γ (IFNγ), but the necessity of these cytokines for disease pathogenesis is unclear. Utilizing HLA-DR3 (DRβ1*0301) transgenic mice lacking IFNγ or IL-17A in … Read more
J Immunol. 2026 Oct 1;215(10):vkag267. doi: 10.1093/jimmun/vkag267. ABSTRACT Manganese ions (Mn2+) are potent immunomodulatory agents that activate the cGAS-STING pathway. While their role as acute adjuvants is well-documented, the innate immune memory (trained immunity) signatures induced by Mn2+ remain unexplored. Using an in vitro priming-rest-challenge model, we demonstrate that transient Mn2+ stimulation induces a persistent … Read more
We present the first report of chicken lipid-reactive, NKT-like TCRVβ2+ T cells that recognize the endogenous ganglioside GM3 presented by chCD1.1 on live antigen-presenting cells. This activation induces a rapid cytokine response from avian lipid-reactive T cells, offering a universal target for lipid-adjuvanted poultry vaccines. ABSTRACT This study presents the discovery and first functional characterization … Read more
This study is focussed on the role of cAMP-dependent transcriptional repressor ICER in regulatory T cell function. Using a conditional knockout model, Treg development, suppressive function, stability, and metabolic phenotype were examined to gain further understanding of the role of cAMP-dependent signalling in regulatory T cells. ABSTRACT Regulatory T cells (Tregs) are essential for immune … Read more
J Immunol. 2026 Oct 1;215(10):vkag250. doi: 10.1093/jimmun/vkag250. ABSTRACT B cell precursor acute lymphoblastic leukemia (BCP ALL) is driven by a combination of genetic alterations that promote invasion and expansion of undifferentiated B cells. Mice that express a NUP98::HOXD13 (NHD13) fusion gene in hematopoietic cells develop a wide range of hematologic malignancy, and when crossed to … Read more
