A metabolic-epigenetic axis controls cell fate transition. Innate immune activation induces glycolysis and facilitates mitochondrial export of citrate to the nucleus. In the nucleus, ATP-Citrate Lyase (ACL) converts citrate to acetyl-CoA. There it serves as the substrate for histone acetylation to increase DNA accessibility, and facilitate cell fate transitions, as in vascular regeneration.
