Abstract

T follicular cells help B cells generate high-affinity antibodies. Two papers in this issue of Immunity (Nurieva et al., 2008, and Vogelzang et al., 2008) have identified a role for interleukin-21 in the development of these specialized cells and highlight questions about how this dedicated population is generated.
