title: Anergic B cells caught in the act.
abstract: Tolerance of B-lymphocytes to autoantigens is established by clonal deletion, receptor editing, and anergy. In this issue of Immunity, Merrell et al. (2006) have now identified that T3 "transitional" B cells in the spleen are not developmental intermediates but rather a major population of anergic B cells.
