Human Normal Peripheral Blood Untouched CD19+/IgD+ Naive B CellsMature nave B cells, not yet been exposed to any antigen, express CD19 as well as IgD. Upon exposure to an antigen in periphery lymphoid organs, mature naive B cells undergo early primary antibody response by secreting antibody in IgM format. In comparison, IgD molecules function mainly as cell surface receptors for the antigen. The activated naive B cell further proliferates and differentiates into either a memory B cell or an effector cell that
