title: Immobile BCRs: the safety on the signal trigger.
abstract: B cell receptor (BCR)-mediated tonic signals are important for B cell survival and development. In this issue of Immunity, Treanor et al. (2010) show that triggering of downstream responses is kept in check with BCR immobilization by actin.
