High affinity tcr
WebT cell receptors (TCR) have a low affinity for the MHC and the presented peptides (MHCpep). The low affinity of the TCR is crucial in T cell recognition and activation. … Web11 de abr. de 2024 · As a consequence a TCR targeting a tumor-associated epitope, can interact with an off-target epitope (OTE) presented on healthy tissue - particularly when using non-autologous TCRs that have not passed thymic selection. Furthermore, the risk of potential immunotoxicity may be increased for the TCRs engineered to enhance pHLA …

Affinity enhancement of TCRs can alter the interface with pHLA. Ensuring that the introduced mutations maintain or even enhance selectivity, relative to other peptides in the self-repertoire, is therefore of critical importance.
