Distribution of hydropathicity index (GRAVY) values of TCR CDR3 sequences of TT-specific T-cell clones derived from BLS allo-BMT recipients 1 and 2 after allo-BMT, and their corresponding donors. A hydropathic index of −5 is considered to be neutral, values above −5 are considered to be hydrophobic, and values below −5 are considered to be hydrophillic; each dot represents a single CDR3 region. (+) Mean value of all different CDR3s of one individual.
