WebThanks to the mix-and-match genetics of antibody production, humans can generate up to one quintillion unique antibodies. B-cells that produce antibodies which happen to match material found inside their own body are destroyed before they make it into the blood stream. Exceptions give rise to a class of disorders known as an autoimmune disease. WebB cells (bursa-dependent lymphocytes) are progenitors of plasma cells that secrete antibodies. while T cells (thymus-dependent lymphocytes) are the mediators of cell-mediated immunity. Macrophages are also components of the immune system, although they do not give rise to sensitized cells themselves or produce antibodies (Figure 6.2). sign master walkthrough guide
