Inactivation of IFNAR1 in CTLs was reported to limit their survival within the TME and undermine the efficacy of chimeric antigen receptor (CAR) T cell treatment in colon cancer models, while genetic stabilization of IFNAR1 improved CTL viability and response to both CAR T cell and anti-PD-1 therapy [103]. The gene discussed is IFNAR1; the disease is colonic neoplasm.
