Differential organization of tonic and chronic B cell antigen receptors in the plasma membrane

Abstract

Signalling of the B cell receptor (BCR) is pivotal for survival and activation of naïve B cells. Here the authors show, using super-resolution microscopy techniques, that BCRs exist primarily as monomers and dimers in resting B cells, and oligomerize only on stimulation, thereby implicating a function of BCR clustering patterns on B cell biology.
