Which cellular proteins are involved in the processing of extracellular proteins for display by class II MHC molecules?
Which cellular proteins are involved in the processing of extracellular proteins for display by class II MHC molecules?
- Proteasomes
- Dendritic cells, macrophages, and B cells
- CD8+ T cells
- Late endosomes and lysosomes (correct)
What is the main function of the class I MHC pathway?
What is the main function of the class I MHC pathway?
- To convert proteins in the cytosol into peptides
- To display antigens on the cell surface for recognition by CD8+ T cells (correct)
- To transport peptides into the ER
- To generate peptide fragments of the antigen
Why do the two pathways of antigen processing involve different cellular proteins?
Why do the two pathways of antigen processing involve different cellular proteins?
- To transport peptides into the ER
- To ensure recognition of antigens from different compartments by different classes of T lymphocytes (correct)
- To display antigens on the cell surface for recognition by CD8+ T cells
- To generate peptide fragments of the antigen
