In view of the increasing evidence of the involvement of CD8+ T cells in the pathogenesis of multiple sclerosis (MS), we have scanned the sequence of the myelin basic protein (MBP), using 162 overlapping nonapeptides, for HLA-class I binding sites. Peptide binding was measured using the recently reported HLA class I α-chain-refolding assay, and the following HLA allelic products were analyzed: HLA-A2 ((*)0201, (*)0204), B27 ((*)2705), B35, B51 and B62. A considerable number of binding peptides were distinguished for each of the allelic products tested. In addition, three interesting points emerged. The first was the identification of several binding peptides which did not contain the known anchor motifs. The second was the evidence that several peptides showed a promiscuous binding profile, being able to bind to different HLA class I molecules that were either allelic or non allelic. The third was that in several cases two consecutive peptides could bind to the same HLA molecule.
