Follicular helper T (TFH) cells, defined by expression of the surface markers CXCR5 and PD-1 and synthesis of IL-21, require upregulation of the transcriptional repressor Bcl6 for their development and function in B cell maturation in germinal centers. We have explored the role of B cells, and the cytokines IL-6 and IL-21, in the in vivo regulation of Bcl6 expression and TFH cell development. We found that TFH cells are characterized by a Bcl6-dependent downregulation of P-selectin glycoprotein ligand-1 (PSGL1, a CCL19- and CCL21-binding protein), indicating that, like CXCR5 and PD-1 upregulation, modulation of PSGL1 expression is part of the TFH cell program of differentiation. B cells were neither required for initial upregulation of Bcl6 nor PSGL1 downregulation, suggesting these events preceded T-B cell interactions, although they were required for full development of the TFH cell phenotype, including CXCR5 and PD-1 upregulation, and IL-21 synthesis. Bcl6 upregulation and TFH cell differentiation were independent of IL-6 and IL-21, revealing that either cytokine is not absolutely required for development of Bcl6+ TFH cells in vivo. These data increase our understanding of Bcl6 regulation in TFH cells and their differentiation in vivo, and identifies a new surface marker that may be functionally relevant in this subset.
