SLA and influenza: Table-3 shows that the binding of candidate epitopes RSNPGSFYW (P1), DFDPLVTFY (P2), AIPSVSIPF (P3), and VVFHAGSLY (P4) with SLA-1*0401 resulted in negative DGbind values with very small Kd. Notice that the DGbind and Kd values of identified cytotoxic T-cell epitopes in this study are comparable to the influenza epitope-SLA complex. Figure-2 shows the plot of sequence position and the RMSD per residue for each complex formed by SLA-1*0401 with P1, P2, P3, and P4, and influenza epitopes.
