title: Establishing the follicular helper identity.
abstract: Among other genes, expression of the Bcl-6 transcriptional repressor distinguishes follicular helper T (Tfh) cells from other helper T cell subsets. In this issue of Immunity, Yu et al. (2009) demonstrate that Bcl-6 directs Tfh cell differentiation.
