Unformatted text preview: RELATIONSHIP BETWEEN THE TWO BRANCHES OF THE IMMUNE RESPONSE The two branches of the immune response are closely interrelated, in several ways: 1. P RODUCTION OF ANTIBODIES---the production of antibodies against many antigens requires the assistance of helper T cells. These antigens are called T-dependent antigens. They are mainly proteins. Steps by which a T-dependent antigen stimulates antibody production: 1) Antigen is ingested and processed by an APC 2) Fragments of the antigen combined with MHC proteins are displayed on the surface of the APC 3) A helper T cell specific to the antigen recognizes and binds to the antigen-MHC complex 4) As described previously, this results in the release of IL-2 by the helper T cell 5) This same IL-2 that causes further proliferation and differentiation among T cells also...
