WebOn the other hand, unfavorable TCR binding may reduce the risk of autoimmune diseases, and in this case, mutants V5Y_Y6V and Y6Q_Y7Q are more effective. Mutants such as Y6V and Y6V_Y7V, which exhibit enhanced binding to pHLA dimers but have little effect on binding affinity to TCR trimers, can also be used as HLA blockers. WebExisting HLA-A2 TCR transgenic mouse models are specific for differentiation antigens gp100 24 and tyrosinase 25 rather than CT antigens, and do not have the broad array of high-affinity TCRs ( ( 12; 26 or the library of high affinity altered peptide ligands (APLs) 14 27 available for the 1G4 TCR.
