Although we cannot exclude that anti-TRBV27 and anti-TRBV28 mAbs may not recognize well these TRBV chains, the overexpression of these segments in the clonotypes that we have analyzed strongly suggests that these TRBV segments are important for melanoma Ag recognition, with TRBV28 being preferentially involved in the interaction between TR and Melan-A. Here, RENBP is linked to melanoma.
