Targeting P4HA1 promotes CD8+ T cell progenitor expansion toward immune memory and systemic anti-tumor immunity
Ma et al. identify P4HA1 as a critical regulator of CD8+ T cell activity in solid tumor microenvironment. P4HA1 induction in CD8+ T cells causes mitochondrial dysfunction and immune exhaustion. P4HA1 inhibition enhances the progenitor CD8+ T cell expansion while mitigating exhaustion, leading to enhanced systemic anti-tumor immunity.
