1. T-cells mature (develop immunocompetence) in thymus 2. B-cells mature in bone marrow 3. Immunocompetent lymphocytes have unique receptors, committing them to binding with a specific antigen (all 10,000 + receptors are the same) 4. Lymphocytes become immunocompetent before exposure to antigens a.ingle antigen can mobilize many lymphocytes, stimulate production of many antibodies 3. Self-antigens-our cells would be antigens to someone else a. MHC proteins (Major Histocompatibility Complex) on cell surface b. MHC proteins bind to antigens in infected cells.
Most, but not all large granular lymphocytes are more commonly known as the natural killer cells (NK cells). The small lymphocytes are the T cells and B cells. Lymphocytes play an important and integral role in the body's defenses. The three major types of lymphocyte are T cells, B cells and natural killer (NK) cells. T cells belong to a group of white blood cells known as lymphocytes and play a central role in cell-mediated immunity.
