Maternal polysorbate 80 intake promotes offspring metabolic syndrome through vertical microbial transmission in mice.

Polysorbate 80 (P80) is an emulsifier extensively produced, consumed and discharged into the environment, consequently making human exposure inevitable. Despite evidence suggesting that P80 intake causes metabolic syndrome (MS) in mammals via microbial perturbation, limited data exist on its transgenerational impacts on offspring. In this study, we found that maternal P80 treatment impaired intestinal barrier integrity, leading to metabolic endotoxemia, low-grade inflammation and MS-related symptoms in C57BL/6J female offspring.
