ImmunityT cells need something to bind to in order to fight off an infection whereas B cells can fight offinfections with independance.In Adaptive ImmunityThis 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 towhere the antigen is present, or where ever it fits. When interactions between helpter t cellsand b cells occur antibodies form. Antibodies and pathogen bind together in the blood to forma 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 ofthe pathogen is presented on the surface of the phagocyte. Helper T cells are specializedsurface proteins that bind to the piece of the pathogen presented on the phagocyte. Helper Tcells disperse chemical signals to activate other immune system responses.
