High-fat diet-induced MAFLD disrupts sleep architecture through hippocampal neuroinflammation and bifurcated IRS-1/Akt/mTOR signaling in mice
This study demonstrates that high-fat diet-induced MAFLD disrupts sleep architecture in mice by triggering hippocampal neuroinflammation and a specific bifurcated dysregulation of the IRS-1/Akt/mTOR signaling pathway, establishing a novel liver–hippocampus–sleep axis.
