4HUU, 4HUV, 4HUW, 4HUX, 4HV8 - PubMed Abstract: 
A reverse-genetics approach has been used to probe the mechanism underlying immune escape for influenza A virus-specific CD8(+) T cells responding to the immunodominant D(b)NP366 epitope. Engineered viruses with a substitution at a critical residue (position 6, P6M) all evaded recognition by WT D(b)NP366-specific CD8(+) T cells, but only the NPM6I and NPM6T mutants altered the topography of a key residue (His155) in the MHC class I binding site ...
