Q

Mechanism of ISCOMs

A

ISCOMs enclose a viral peptide
ISCOM fuses with APC (and releases viral peptide inside)
Peptide gets attached to MHC I and activates CD8 T cell

Q

Peptide vaccine steps for malaria

A

Identify good candidate peptides (in this case small because it’s an MHCI and pro as second AA)

Test for high binding to HLA(B53) - high binding because it’s a MHCI

Test for proliferation if T cells from infected malaria patients

Q

How does anti MHC II antibody therapy work

A

Normally:
Oligodendrocytes release myelin basic protein (MBP) which the macrophage engulfs
Th1 cells with receptors for MBP bind macrophage and get activated
Th1 cells then activate macrophage to kill oligodendrocytes

If you use anti MHCII Ab, will bind to macrophage so it can’t interact with Th1

If use
