The immune system contains the innate immunity system and the adaptive immunity system. 2. The innate system uses a Toll-like receptor that binds to the PAMP lipopolysaccharide structure on the surface of Gram negative bacteria. 3. The adaptive immune system system contains two major groups of lymphocytes (immune system cells), B cells and T cells. B cells are involved in the production of antibodies and T cells are involved in both cellular killing, as well as stimulation of the B cells. 4. Immunoglobulin G (IgG) is one of five major antibody classes made by the B lymphocytes of the humoral immune system (cellular immune system described below). IgG is the most abundant antibody in the blood serum. Others include IgA (in mucus), IgM (early responder), IgD (function uncertain), and IgE (parasite protection). 5. The structure of antibodies has several common features. First, they are composed of two sets of Heavy (H) and light (L) chains arranged in a Y shape. Both the H and L chains have constant and ...
