  • On which cell types are Class II MHC proteins found?
    B) Antigen-presenting cells
  • Which proteins on the antigen-presenting cell are recognized by the helper T-cell?
    MHC class II proteins are recognized by helper T-cells (CD4 cells).
  • Which class of MHC proteins presents exogenous antigens?
    MHC class II proteins present exogenous antigens.
  • Where are MHC molecules located on a cell?
    MHC molecules are located on the surface of host cells.
  • On which cells are class I major histocompatibility complex (MHC) molecules found?
    A) Found on all nucleated cells
  • What happens if a transplanted organ's MHC cells don't match those of the recipient?
    The recipient's immune system may recognize the transplanted organ as foreign and reject it.
  • What is the function of MHC II proteins?
    MHC II proteins present exogenous antigens to helper T-cells (CD4 cells).
  • Which type of antigen-presenting molecule is found on all nucleated cells?
    MHC class I molecules are found on all nucleated cells.
  • Which MHC complex is found on all nucleated cells?
    MHC class I complex is found on all nucleated cells.
  • On which cells are MHC II proteins found?
    D) Found on antigen-presenting cells
  • What type of antigens do MHC I proteins present?
    D) Present endogenous antigens
  • On which cells are Class II MHC molecules found?
    B) Antigen-presenting cells
  • What best describes the binding of the CD4 and CD8 co-receptors to MHC molecules?
    CD4 co-receptors bind to MHC class II molecules, while CD8 co-receptors bind to MHC class I molecules.
  • Which cell type does not express MHC class II molecules on its surface?
    D) Muscle cells
