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. WebMemory B cells express the same membrane-bound antibody as the original naive B cell, or the “parent B cell”. Plasma B cells produce the same antibody as the parent B cell, but they aren’t membrane bound. Instead, plasma B cells can secrete antibodies.
