J Immunol. 2026 Oct 1;215(10):vkag278. doi: 10.1093/jimmun/vkag278. ABSTRACT Heat shock proteins (HSPs) are an abundant class of proteins well known for their functions in protein folding and molecular chaperoning within all compartments of a cell. These functions are fundamental in all single and multicellular organisms, and so HSPs have remained relatively conserved in structure throughout … Read more
J Immunol. 2026 Oct 1;215(10):vkag290. doi: 10.1093/jimmun/vkag290. ABSTRACT Age-associated B cells (ABCs) have emerged as critical components of adaptive immune responses linked to autoimmune disorders, aging-associated diseases, and chronic infections. Accumulation of ABCs is subjected to sex-specific regulation. A group of X-linked genes, including TLR7 and CXorf21/TASL, an adaptor that regulates IRF5 activity, are key … Read more
J Immunol. 2026 Oct 1;215(10):vkag277. doi: 10.1093/jimmun/vkag277. ABSTRACT Maternal immunity is a key mechanism of early defense in vertebrates. Among the various maternal molecules, antibodies (Abs) play a crucial role. In teleost fish, immunoglobulin M (IgM) is the earliest discovered and most abundant Ab type. However, the maternal immune function of teleost IgM is still … Read more
J Immunol. 2026 Oct 1;215(10):vkag283. doi: 10.1093/jimmun/vkag283. ABSTRACT The lymphatic system is essential for the development of innate and adaptive immune responses to pathogens, including during viral infection and vaccination. Functioning as an integrated network composed of lymphatic vessels, lymphoid organs, and fluid, it serves as a central hub for viral entry, recognition, trafficking, replication, … Read more
J Immunol. 2026 Oct 1;215(10):vkag279. doi: 10.1093/jimmun/vkag279. ABSTRACT Eosinophils are pleiotropic cells and can respond to a wide array of inflammatory stimuli, including respiratory viral infection. Although they are historically associated with adverse outcomes in vaccinated hosts after breakthrough infection, such as during vaccine-associated enhanced respiratory disease (VAERD) for respiratory syncytial virus (RSV), eosinophils can … Read more
J Immunol. 2026 Oct 1;215(10):vkag262. doi: 10.1093/jimmun/vkag262. ABSTRACT Epidemiologic studies suggest that patients with pre-existing type 1 diabetes have a decreased risk of developing melanoma, prostate cancer, and breast cancer, although the underlying mechanism remains unresolved. In translational model studies, we observed that a streptozotocin-induced high blood glucose model exhibited restricted melanoma and carcinoma (mammary, … Read more
J Immunol. 2026 Oct 1;215(10):vkag245. doi: 10.1093/jimmun/vkag245. ABSTRACT Systemic lupus erythematosus is sustained by dysfunctional Th cells that amplify autoreactive B-cell responses. Iberdomide, a cereblon modulator that degrades Ikaros and Aiolos, has shown clinical activity in lupus, yet its T cell-centric mechanism remains incompletely defined. Here, using purified Th cells and a PBMC-based T-B cell … Read more

J Immunol. 2026 Oct 1;215(10):vkag271. doi: 10.1093/jimmun/vkag271. ABSTRACT Mucosa-associated invariant T (MAIT) cells are innate-like MR1-restricted T cells broadly distributed in human tissues. MAIT cells adapt their antigen-specific response patterns depending on cytokine cues such as IL-12 or IL-18 in the microenvironment, shifting toward either IL-10+ or IL-17+ profiles. However, if such patterns are maintained … Read more
J Immunol. 2026 Oct 1;215(10):vkag286. doi: 10.1093/jimmun/vkag286. ABSTRACT We investigated the development, antigen specificity, and effector functions of PD-1- and PD-1+ CXCR5+CD8+ T-cell subsets in transplant mice with acute murine cytomegalovirus (MCMV) infection. MCMV-primed (MCMV-Tet+) or alloprimed (MCMV-Tet-) CD8+ T cells from C57BL/6 mice were flow-sorted and adoptively transferred into MCMV-infected CD8 knockout transplant recipients. … Read more
