title: Computer simulations to predict the availability of peptides with known HLA class I motifs possibly generated by proteolysis of HIV-1 proteins in infected cells.
abstract: Cytotoxic T cells that recognize HIV-1 peptides generated from all viral proteins were reported. To predict the cleavage pattern of HIV-1 proteins by cytoplasmic proteasomes into peptides with motifs fitting known HLA class I molecules, the computer program Findpatterns was used. In this paper the combined amino acids patterns for proteolytic cleavages and the HLA class I haplotype-restricted peptides motifs are studied. It was noted that peptides with motifs of HLA class I A2 and A68 were abundant compared with HLA class 5B2, B8, B53, and B35.
