Question

Which sequence of events correctly describes the MHC class 1 antigen presentation pathway?

Accepted Answer

Pathogen degradation by proteasome, peptide transport into ER by TAP, binding to MHC class 1, transport to cell surface, activation of cytotoxic T cells.

Answer

Pathogen degradation by proteasome, peptide transport into Golgi, binding to MHC class 1, transport to cell surface, activation of helper T cells.

Answer

Pathogen uptake by endocytosis, degradation in lysosome, binding to MHC class 2, transport to cell surface, activation of helper T cells.

Answer

Pathogen degradation in lysosome, peptide transport into ER by TAP, binding to MHC class 1, transport to cell surface, activation of regulatory T cells.
