B lymphocytes produce antibodies - proteins (gamma globulins) that recognise foreign substances (antigen) and attach themselves to them. Adaptive immune responses are carried out by white blood cells called lymphocytes. There are two broad classes of such responses—antibody responses and cell-mediated immune responses, and they are carried out by different classes of lymphocytes, called B cells and T cells.
