Foxp3 drives oxidative phosphorylation and protection from lipotoxicity.
Tregs can adopt a catabolic metabolic program with increased capacity for fatty acid oxidation-fueled oxidative phosphorylation (OXPHOS). It is unclear why this form of metabolism is favored in Tregs and, more specifically, whether this program represents an adaptation to the environment and developmental cues or is "hardwired" by Foxp3. Here we show, using metabolic analysis and an unbiased mass spectroscopy-based proteomics approach, that Foxp3 is both necessary and sufficient to program Tr...Expand abstract
