Detailed explanation-1: -There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body’s own cells that have themselves been taken over by viruses or become cancerous.
Detailed explanation-2: -B cells recognize free, unprocessed antigens. T cells recognize antigens within a complex of cell surface proteins called the major histocompatibility complex (MHC) on the surface of antigen-presenting cells (also called accessory cells).
Detailed explanation-3: -Both types of T-cell receptor differ from the membrane-bound immunoglobulin that serves as the B-cell receptor: a T-cell receptor has only one antigen-binding site, whereas a B-cell receptor has two, and T-cell receptors are never secreted, whereas immunoglobulin can be secreted as antibody.
