My guess is that alot depends on the antigen/APC combination moreso than 
the MHC allele although my prediction doesn't preclude association with 
MHC and, in fact, certain alleles will obviously present the same 
peptides with greater or lessor affinities, or will present different 
peptides from the same parent molecules.
