Activated B cell enter germinal centers (GC) to become plasma cells and memory B cells. Here the authors show that some memory B cells recycle to GC via CCL-21 mediated chemotaxis to deliver antigens from the lymph node subcapsular sinus (SCS) to potentially contribute to affinity maturation and antigenic drift.
