B Cell Antibody Production

B cell antibody production refers to the process by which B lymphocytes (B cells) generate and secrete antibodies in response to antigens. Each B cell produces a unique antibody, determined by its specific antigen-binding site. This process is central to humoral immunity, enabling the body to recognize and neutralize pathogens such as bacteria and viruses. Upon encountering an antigen that matches their membrane-bound antibody (the B cell receptor, or BCR), naïve or memory B cells become activated—often with help from helper T cells. Activated B cells proliferate and differentiate into plasma cells, which secrete large quantities of soluble antibodies into circulation. Some activated B cells become memory B cells, providing long-term immunity.

Not applicable; B cell antibody production is a biological process, not a molecular target.
