title: Gut immune balance is as easy as S-F-B.
abstract: Microbes appear to modulate homeostatic plasticity of T helper and T regulatory cells. In this issue of Immunity, Gaboriau-Routhiau et al. (2009) now reveal that segmented filamentous bacteria uniquely coordinate the intestinal T cell profile. The potential implications of this process to various immune functions are discussed.
