From:  Probing and enhancing tumor-infiltrating lymphocytes: insights from single-cell technologies and genetic reprogramming

 Key genetic and epigenetic targets in TIL reprogramming.

CategoryTargetEffect
Genetic engineeringPD-1, LAG-3, TIM-3Knockout reverses exhaustion, enhances effector functions
Genetic engineeringIL-2R, IL-7ROverexpression improves proliferation and persistence
Genetic engineeringCAR integrationEnhances antigen specificity and bypasses MHC restrictions
Epigenetic reprogrammingHDACs, DNMTsModulation restores effector gene accessibility, reverses exhaustion
Epigenetic reprogrammingMemory-associated genesEnhances persistence and memory-like phenotypes

TIL: tumor-infiltrating lymphocyte; MHC: major histocompatibility complex.
