Empty MHC Class I and MHC Class II Molecules Are

question 7

Multiple Choice

Empty MHC class I and MHC class II molecules are rapidly removed from the cell surface. This process prevents:

• A) The accumulation of empty MHC molecules on the cell surface which would interfere with T cells recognizing pathogen-derived peptide:MHC complexes
• B) Pathogens from evading the immune response by inducing peptide release from cell surface MHC molecules
• C) MHC class I molecules from being internalized into endosomes and binding endosome-derived peptides
• D) HLA-DM from trafficking to the cell surface with MHC class II
• E) Inappropriate T cell recognition of healthy cells that are not infected, nor have ingested a pathogen
