Intestinal epithelial chemokine (C-C motif) ligand 7 overexpression enhances acetaminophen-induced hepatotoxicity in mice
Acetaminophen (APAP) overdose –induced hepatotoxicity is the leading cause of drug-induced liver injury worldwide. The related injury pathogenesis is mainly focused on the liver. Here, we report that gut barrier disruption may also be involved in APAP hepatotoxicity. APAP administration led to gut leakiness and colonic epithel ial chemokine (C-C motif) ligand 7 (CCL7) up-regulation. Intestinal epithelial cell (IEC)-specific CCL7 transgenic mice (CCL7tgIEC mice) showed markedly increased myosin light chain kinase (MLCK) phosphorylation and elevated gut permeability and bacterial translocation into the liver compared to wil d-type mice.
