High affinity class-switched antibodies and memory B cells are products of the germinal center. The CD4+ T cell help required for the development and maintenance of the germinal center is delivered by follicular helper T cells (TFH), a CD4+ helper T cell subset characterized by expression of Bcl-6 and secretion of IL-21. The cellular interactions that mediate differentiation of TFH and GC B cells remain an important area of investigation. We previously showed that MHC class II-dependent DC antigen presentation is sufficient for the differentiation of a TFH intermediate (termed pre-TFH), characterized by Bcl-6 expression but lacking IL-21 secretion. Here we examine the contributions of MHCII antigen presentation by B cells to TFH differentiation and GC responses in several contexts. B cells alone do not efficiently prime naïve CD4+ T cells or induce TFH following protein immunization; however, during LCMV infection B cells induce TFH differentiation despite the lack of effector CD4+ T cell generation. Still, MHCII-positive DCs and B cells cooperate for optimal TFH and GC B cell differentiation in response to both model antigens and viral infection. This study highlights the roles for B cells in both CD4+ T cell priming and TFH differentiation and demonstrates that different APC subsets work in tandem to mediate the germinal center response.
