b cell

İngilizce Anlamı - English Translation

1. beta cell, cell in the pancreatic islets which produces and secretes insulin (Physiology); type of lymphocyte produced in the bone marrow, precursor of antibody-producing plasma cells (Immunology).
2. a lymphocyte derived from bone marrow that provides humoral immunity; it recognizes free antigen molecules in solution and matures into plasma cells that secrete immunoglobulin that inactivate the antigens.
3. Any of the lymphocytes that mature in the bone marrow and, when stimulated by a particular antigen, differentiate into plasma cells. Also called B lymphocyte. One of the two types of lymphocytes (the others being T cells). All lymphocytes begin their development in the bone marrow. B cells are involved in so-called humoral immunity; on encountering a foreign substance (antigen), the B lymphocyte differentiates into a plasma cell, which secretes immunoglobulin (see: antibody).
