  Objective: Establishing an effective humoral immunity is an important host defense mechanism in intestinal mucosa. T follicular helper (Tfh) cells are a spectrum of CXCR5 expressing T helper cells that induce antigenspecific B cell differentiation. Because the differentiation of T helper cells is largely regulated by innate immunity, we addressed whether TRIF signaling regulates Tfh cell differentiation and its ability to trigger humoral immune responses in the intestine. Method: CD4+CXCR5+ T cells, B cells, and plasma cells in the Peyer’s patches (PPs) of WT and TRIF-deficient (TrifLPS2) mice were analyzed by flow cytometry at the baseline, 9 days post primary infection, and 7 days postsecondary infection with Y. enterocolitica. Y. enterocolitica-specific CD4+CXCR5+ T cells were generated in vitro by co-cultu.. View More»
