B-lymphocytes (B-cells) are responsible for the production of antibody molecules during adaptive immunity. These lymphocytes are produced in the bone marrow and differentiate into antibody-secreting plasma cells. Plasma cells are activated B cells that secrete antibodies, which bind to specific antigens for immune responses.
