Limited plasticity in the recognition of peptide epitope variants by an alloreactive CTL clone correlates directly with conservation of critical residues and inversely with peptide length.

Although self-restricted T cells are peptide-specific and can distinguish among closely related ligands, they have some flexibility in the recognition of sequence variants of their …

The same natural ligand is involved in allorecognition of multiple HLA-B27 subtypes by a single T cell clone: role of peptide and the MHC molecule in alloreactivity.

The human alloreactive CTL clone 27S69, raised against B*2705, cross-reacts with B*2702 and B*2703, but not with B*2701, B*2704, B*2706, or B*2710.
