MLANA and melanoma: The finding of a conserved amino acid motif in the CDR3, together with the selective use of certain TRBJ and TRBV segments, indicates an important role of the TRB chain in fine-tuning TR affinity of Melan-A-specific T cells of melanoma patients and argues against the hypothesis that high affinity TRs against self-Ags, like Melan-A, are removed during selection in the thymus or, alternatively, by tumor-induced deletion of dominant TR clonotypes [65].
