CD19 is essential for B cell activation by promoting B cell receptor–antigen microcluster formation in response to membrane-bound ligand


Here we describe the spatiotemporal architecture, at high molecular resolution, of receptors and signaling molecules during the early events of mouse B cell activation. In response to membrane-bound ligand stimulation, antigen aggregation occurs in B cell antigen receptor (BCR) microclusters containing immunoglobulin (Ig) M and IgD that recruit the kinase… (More)
