title: Strength of T cell receptor signaling strikes again.
abstract: In this issue of Immunity, Gomez-Rodriguez et al. (2009) demonstrate that signaling via the Itk kinase, a component of the T cell receptor signaling pathway, is required for interleukin-17A but not interleukin-17F expression in T helper 17 cells.
