Compartment-specific PPARδ activity controls the outcome of cancer-immune cell competition and immunotherapy efficacy
These findings identify compartment-specific PPARδ activity as a targetable driver of immune cell fitness that can be harnessed to improve outcomes in immunotherapy-resistant tumors. Therapeutically, PPARδ-activated CD8 + T cells sensitize immunotherapy-resistant microsatellite stable metastatic colorectal cancer to checkpoint blockade in mice, and pharmacological or genetic PPARδ activation enhances human chimeric antigen receptor T cell function.
