to delineate the nature of the trimolecular complex , consisting of the t-cell receptor , mbp-peptide fragment , and mhc molecule ( i-au ) , we have synthesized 13 variants of the 9-mer n-terminal immunodominant peptide differing at residue 4 and studied their immune recognition in vitro and in vivo .
