CRISPR/Cas9-Mediated PD-1 Engineered T Cells: New Strategy to Block Tumor Immune Escape
At present, overexpression of immune-related genes is one of the key mechanisms of tumor immune evasion. As a tumor cell-mediated immune escape core checkpoint molecule, the PD-L1 (programmed death ligand 1) will recruit SHP-1/SHP-2 (Src homology phosphotyrosyl phosphatase 1/ Src homology phosphotyrosyl phosphatase 2)...
