Protocol for acquiring samples to assess the impact of microplastics on immune microenvironments in the mouse intestine

Abstract

Summary: Environmental nano- and microplastics (NMPs) pose serious environmental issues, yet there is no established technique to assess their impact on health through oral ingestion. Here, we present a protocol to assess the impact of NMPs in the intestinal immune microenvironments by employing chronic exposure to NMPs in a mouse model. We describe steps for administration of NMPs, feces and tissue collection, and colonic gut digestion. We then detail procedures for isolation of intestinal immune cells and RNA isolation.For complete details on the use and execution of this protocol, please refer to Harusato et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
