Abstract:Dysregulated macrophage responses and changes in tissue metabolism are hallmarks of chronic, sterile inflammation. However, the extrinsic and intrinsic metabolic cues that direct and support macrophage functions are poorly understood. Here, we discover that during sterile inflammation in skin, the epidermal and macrophage compartment uniquely depend on glycolysis and TCA cycle, respectively. This compartment separation of the central carbon respiration chain is initiated by enhanced HIF1a expression in the epi… Show more
