Flow of work by Amir et al.1 Peptide specificities presented in conjunction with HLA-A*0201 were identified for the clone with 2 specificities and for 6 of the clones with a single specificity. Experiments with silencing hairpin RNA sequences that suppressed specific gene expression confirmed that no other peptides were recognized by 4 of the 6 clones with single peptide specificities or by the clone with 2 peptide specificities. Two of the clones that recognized a single peptide were not tested in this type of experiment. Professional illustration by Paulette Dennis.
