Production of T cells with enhanced antigen discrimination power
Applications: CAR-T cell therapy
Generation of T cells with genetic modifications that enhance their discriminatory powers resulting in highly potent on-target responses with dramatically lower off-target cross-reactivity without modifying the TCR.
Features
Benefits
Reduces cross-reactivity by modifying genes extrinsic to the TCR
Uses existing candidate TCRs (i.e. no modifications to the TCR are required)
Maintains on-target potency
Modified signalling enables selective responses to high affinity on-target antigens
Reduced or abolished responses to lower-affinity off-target antigens (i.e. reduced cross-reactivity)
Simple genetic modifications
Dramatic ~10,000-fold reduction in cross-reactivity.
