MHC class I molecules present peptide antigens derived from a(n) _______
MHC class I molecules present peptide antigens derived from a(n) _______
Homework Answers
I believe the correct answer to be:
Viruses or endogenous infections. Meaning the antigens that are picked from inside the cell.

Why are MHC molecules able to bind a variety of peptides? 1. the peptide-binding groove of a specific MHC molecule can bind several peptides simultaneously 2. The MHC genes undergo somatic recombination to produce thousands of MHC molecule variants 3. MHC bind very loosely and transiently to peptide antigens, so a wide variety of peptide antigens can bind any specific MHC molecule 4. a small number of amino acids in the peptide antigen bind specifically to complementary pockets in the...

During negative selection MHC class I and Il molecules on the surface of thymic epithelial cells Select one: Present peptides derived from self proteins present in the thymus b. Do not have any peptides bound to them c. Present only peptides derive from self proteins transported to the thymus from the periphery d. Present only peptides derived from self MHC molecules

Handout IG2-2 Class I MHC-Peptide Interactions Place the steps of the antigen-processing pathway for endogenous antigen in the correct order Alpha chain of class I MHC binds peptide. Endogenous antigen within cytosol is degraded by proteasome. Peptides are transported into endoplasmic reticulum by TAP Alpha chain of class I MHC binds β2-microglobulin. Peptide-class I MHC is transported to Golgj complex and then to cell surface. Class I MHC peptide binds to CD8+T cell.
