Differentiation of B cells and T cells in the primary lymphoid organs results in the expression of several characteristic surface markers,such as CD4 on helper T cells,CD8 on cytotoxic T cells,and CD21 and CD40 on B cells.Clonal selection is the process during which antigens select those lymphocytes with complementary T-cell receptors (TCRs)or BCRs.
