Antibodies are immunoglobulins produced by which cells in response to antigens?

Antibodies are immunoglobulins produced by B lymphocytes, specifically by plasma cells that differentiate from B cells after activation. When a B cell encounters its specific antigen (often with help from helper T cells), it proliferates and becomes a plasma cell that secretes large quantities of antibodies into the bloodstream. These antibodies bind the antigen, helping neutralize pathogens, mark them for destruction, and sometimes activate complement. Other listed cells have different roles: cytotoxic T lymphocytes kill infected cells rather than produce antibodies, erythrocytes carry oxygen, and platelets are involved in clotting. So the cells responsible for antibody production are B lymphocytes and their plasma-cell descendants.
