Sustained exogenous Notch2 signaling prompts Follicular B cells to trans-differentiate into Marginal Zone B cells. This study reveals that under physiological conditions, Notch2 signalling regulates a fate choice in antigen activated Follicular B cells, dictating whether they develop into Germinal Center B cells or Marginal Zone B cells.
