J Immunol. 2026 Jul 10;215(7):vkag154. doi: 10.1093/jimmun/vkag154. ABSTRACT The postnatal T‑cell pool comprises cells at diverse developmental stages, complicating efforts to resolve T‑cell differentiation, maturation, and long‑term adaptation. To address this challenge, we developed Rag1‑mediated time-stamp tracing, a genetic strategy that enables time‑resolved tracking of T‑cell developmental origins. We validate the specificity and temporal resolution … Read more

J Immunol. 2026 Jul 10;215(7):vkag172. doi: 10.1093/jimmun/vkag172. ABSTRACT The growing food allergy epidemic is thought to be related to changing environmental factors, particularly changes in the gut microbiome. While prior work has demonstrated that food allergy can be modulated by gut microbes, little is known about how food allergen-specific CD4+ T cells are affected by … Read more

J Immunol. 2026 Jul 10;215(7):vkag173. doi: 10.1093/jimmun/vkag173. ABSTRACT Anti-TNF and anti-IL-12/IL-23 are commonly used therapies for immune-mediated inflammatory diseases (IMIDs), including inflammatory bowel disease (IBD). Although several studies have shown intact T cell responses following 2 to 3 doses of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in biologics treated IMID patients, our group … Read more

J Immunol. 2026 Jul 10;215(7):vkag205. doi: 10.1093/jimmun/vkag205. ABSTRACT Our laboratory has previously described a mouse model (CD40LΔ5) that produces 60% of wild-type CD40L due to a targeted deletion in an RNA binding site within the CD40L message. The CD40LΔ5 mutation, which destabilizes CD40L mRNA during T-cell activation, causes disrupted germinal center (GC) formation, leading to … Read more
