    Liu et al. (2026) delineate the adverse outcome pathway (AOP) of triclosan (TCS)-induced liver fibrosis, highlighting TGF-β1 and AGEs-RAGE roles.

  • 2

    The model presented overlooks TCS's identity as a potent antimicrobial, focusing solely on its chemical stressor effects.

  • 3

    Exposure to TCS through lactation and oral gavage leads to significant disruption of the neonatal gut microbiome.

  • 4

    Microbial dysbiosis compromises intestinal barrier integrity, allowing lipopolysaccharide (LPS) delivery to the liver.

  • 5

    The authors suggest that microbial dysbiosis and endotoxemia may be the primary events driving TGF-β1 surge in liver fibrosis.
