Metaproteomics reveals associations between microbiome and intestinal extracellular vesicle proteins in pediatric inflammatory bowel disease

Abstract

Gut microbial dysbiosis has been implicated in the pathogenesis of inflammatory bowel disease. Here, the authors examine host-microbiota protein interactions that occur in inflammatory bowel disease; they show an upregulation in proteins related to antimicrobial activities, and alterations in intestinal extracellular vesicles that are associated with aberrant microbiota-interactions.
