WebLastly, we find that several p6 mutants can increase pHLA-TCR affinity, while a swap p5-p6 tyrosine–valine (V5Y+Y6V) and a p6-p7 glutamine–glutamine (Y6Q ... pHLA-TCR systems with high CD69 activation but low affinity are optimized by adding polar and charged residues that form transient hydrogen bonds to enhance the pHLA–TCR catch bond ... WebBecause my model learns the high affinity TCR sequences with a given cancer type, it can also be used to detect high affinity CDR3 regions from the patient’s TCR repertoire, yielding the probability of early cancer diagnosis. I design a test in which the patient’s TCR repertoire is extracted from a peripheral blood test and screened
