Long-term consumption of a calorie-rich diet persistently activates brain microglia. Here, the authors show that microglial activity in mouse brains oscillates daily in conjunction with feeding, and that TNFα, secreted by activated microglia, induces mitochondrial stress in satiety-promoting POMC neurons.
