The affinity of a T cell receptor (TCR) presenting to peptide:MHC profoundly impacts the phenotype and function of effector and memory cell differentiation. Significantly, blockade of TNFR2 attenuated graft being rejected in low but not high affinity primed animals. These data establish a functional connection between TNF signaling and TCR priming affinity and have ramifications… Continue reading The affinity of a T cell receptor (TCR) presenting to peptide:MHC
