What is the function of MHC? Which cells make MHC I, and which make MHC II? What WBCs can present antigens in MHC II?
Generally speaking, what kinds of cells express MHC I, MHC II, or both? What is presented on MHC I and II, and what kind of T cell recognizes each one? What response occurs when a T cell recognizes what is being presented on MHC I? What happens if it recognizes MHC II? Give an example of each type of recognition.
What polypeptide chains make up the MHC class molecule? MHC class II?

MHC I proteins are found on the surface of antigen-presenting cells and display exogenous antigens, while MHC II proteins are found on the surface of most cells, and display endogenous antigens. MHC I proteins are found inside most cells, and display exogenous antigens, while MHC II proteins are found on the surface of antigen-presenting cells and display endogenous antigens. MHC I proteins are found inside all cells and display exogenous antigens, while MHC II proteins are found inside antigen-presenting cells and display endogenous antigens.
