Mefloquine enhances the efficacy of anti-PD-1 immunotherapy via IFN-γ-STAT1-IRF1-LPCAT3-induced ferroptosis in tumors.

In conclusion, our study demonstrated a novel mechanism by which LPCAT3 is regulated, and demonstrated that Mef is a highly promising new target that can be utilized to enhance the efficacy of anti-PD-1 immunotherapy.
