Immune System (Antibody Production)

Molecular classification
Immune System Process, B Lymphocyte, Plasma Cell, Antibody / Immunoglobulin
01

Overview

The immune system's antibody production is a critical process involving B lymphocytes that produce antibodies (immunoglobulins). These antibodies bind to antigens on pathogens or foreign substances, marking them for destruction or removal. Key functions include neutralizing toxins, opsonizing pathogens, activating complement, and mediating antibody-dependent cellular cytotoxicity. There are five main classes of antibodies: IgG, IgM, IgA, IgE, and IgD, each with specialized roles. Engineered monoclonal antibodies are used in diagnostics and therapy.
