When an antigen (a particular foreign protein, such as a substance on the surface of a bacterium) is encountered by the immune system, certain B-lymphocytes are stimulated to enlarge and undergo cell division, transforming into cells called plasma cells. The plasma cells secrete into the blood vast numbers of tailor-made immunoglobulins that attach to the antigen on the surface of the microorganism.
Disorders connected with B-cellsB-cell acute lymphocytic leukemia is a type of leukemia (blood cancer) in which too many B-cell lymphoblasts (immature white blood cells) are found in the blood and bone marrow. It is the most common type of acute lymphoblastic leukemia (ALL). Also called precursor B-lymphoblastic leukemia and B-cell acute lymphoblastic leukemia.
B-cell lymphoma is a type of cancer that forms in B cells. B-cell lymphomas usually occur in adults and may be either indolent (slow-growing) or aggressive (fast-growing). There are many different types of B-cell lymphomas, and prognosis and treatment depend on the type and stage of cancer.
