The schematic diagram for the mechanism of the therapeutic effect of MMVs on intestinal barrier function after sepsis. MMVs delivered mfn2, PGC-1α, and functional mitochondria to intestinal epithelial cells and synergistically restored the mitochondrial dynamic balance by promoting mitochondrial fusion and biogenesis, and subsequently improved mitochondrial oxidative phosphorylation and metabolism, thereby improving the intestinal barrier function
