|another name for B-lymphocyte|
B cell n.
See beta cell.
A type of lymphocyte that, when stimulated by a particular antigen, differentiates into plasma cells that synthesize the antibodies that circulate in the blood and react with the specific antigens. Also called B lymphocyte.
Any of the lymphocytes that develop into plasma cells in the presence of a specific antigen. The plasma cells produce antibodies that attack or neutralize the antigen in what is called the humoral immune response. B cells mature in the bone marrow before being released into the blood. Also called B lymphocyte. Compare T cell.
One of two main types of immune system lymphocytes (compare T-cell). B-cells originate and develop in the bone marrow and circulate throughout the blood and lymph fluids, recognizing foreign bacteria, viruses, and toxins and binding to them to facilitate their disposal by other cells.
