Do MHC class II receptors have all contents of the cell presented on them?
Homework Answers
MHC class II molecules are a class of major histocompatibility complex (MHC) molecules found on relatively specialized immune cells such as dendritic cells, B cell , macrophage and thymic epithelial cell .
Only extracellular antigens are presented by class II MHC
The Basic sequence of its function are:
- First a extracellular pathogen is phagocytosed and surrounded by a phagocytic vesicle.
- A lysosome with proteases fuses with the phagocytic vesicle and then degrade the pathogen into small peptides
- Meanwhile MHC II molecule is synthesized in the rough ER.
- Vesicle containing MHC II molecule fuses with the vesicle containing the peptides, and a peptide bind to MHC II molecule.
- Then exocytosis occurs.
- The peptide and MHC II molecule are now presented on the cell surface and recognized by a specific T cell receptor on a T cell.
Thus , as exogeneous antigens are presented by class II MHC so MHC class II receptors don’t have all contents of the cell presented on them
