Unlike MHC I, MHC II is meant to present extracellular pathogens rather than intracellular. Furthermore, the first step is to acquire the pathogen through phagocytosis. The pathogen is then broken down in a lysosome and a desired component is then acquired and loaded onto a MHC II molecule. The MHC II molecule then travels to the surface to present the antigen to a helper T cell. MHC II active helper T cells which help release cytokines and other things which will help induc… WebHelper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only. The T cell receptor is found on both CD4+ and CD8+ T cells. arrow_forward.
