In this issue of Immunity, Brodeur et al. show that C4b binding protein (C4BP), a regulator component of the classical complement (C) pathway, can bind to CD40 receptors on B cells and activate them. This suggests a novel way by which CD40 may function to bridge innate and adaptive immune responses.
