Immunity T cells need something to bind to in order to fight off an infection whereas B cells can fight off infections with independance. In Adaptive Immunity This immune response is enhanced by previous exposures to the infecting pathogen. The pathogen, helper t cell, and b cell are put together. The helper T cell and b cell bind to where the antigen is present, or where ever it fits. When interactions between helpter t cells and b cells occur antibodies form. Antibodies and pathogen bind together in the blood to form a lump. Antibodies help to fight off infections in the bodies fluids. In a cell mediated response, (cytotoxic cells defend against infection in body cells) a pathogen is engulfed by a phagocyte and endocytosis of the pathogen occurs. A piece of the pathogen is presented on the surface of the phagocyte. Helper T cells are specialized surface proteins that bind to the piece of the pathogen presented on the phagocyte. Helper T cells disperse chemical signals to activate other immune system responses.
