Bone marrow-derived lymphocyte, expressing an antigen-receptor complex composed of membrane-bound immunoglobulin (Ig) and associated molecular chains.
Note: B-cell receptors (BCRs) interact with epitopes directly [no major histocompatibility complex (MHC) restriction]. Mature activated B lymphocytes (plasma cells) produce antibody and are efficient antigen-presenting cells (APCs).
