Web12 de abr. de 2024 · When transduced into patient T cells, high-affinity TCRs were able to control viral replication ( 4 ). When expressed as a soluble TCR linked to a CD3-specific single–chain antibody, the chimeric protein was able to redirect polyclonal CD8 + T cells to kill CD4 + T cells harboring reactivated HIV ( 5 ). 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.
