2. A pharmacologist discovers a new fungal metabolite with unusual antimicrobial properties. It naturally concentrates in the endosomes, lysosomes, and phagolysosomes of cells and directly kills microorganisms (eg, Mycobacterium tuberculosis) that are normally resistant to degradation in the phagolysosomes. It has the undesirable effect of raising the pH within phagolysosomes. Which of the following processes will be primarily affected? A) Class I MHC molecule peptide loading o B) Class II MHC molecule peptide loading C) B-Microglobulin surface expression D) Peptide binding to TCRaß E) Peptide binding to TCRYS
