The Effect of polystyrene nanoparticles on endoplasmic reticulum UPR and intestinal microbial homeostasis in aged mice

With the widespread use of plastic particles, the problem of plastic pollution is becoming more serious. While plastic products bring convenience to people's lives, they also harm the ecosystem and human health. The purpose of this study is to explore the effects of polystyrene nanoparticles on aging of aged mice and explore its related molecular mechanisms, which we hope can provide effective theoretical basis for the prevention and treatment of diseases in elderly individuals.
