Production of a Functional Factor, p40, by Lactobacillus rhamnosus GG Is Promoted by Intestinal Epithelial Cell-Secreted Extracellular Vesicles.

ABSTRACT: The symbiotic relationship between the gut microbiome and the host provides a nutrient-rich environment for gut microbes and has beneficial effects on host health. Although the composition of the gut microbiome is known to be influenced by both host genetics and environmental factors, host effects on the activities and functions of the gut microbial communities remain poorly understood. Intestinal epithelial cells exert front-line responses to gut microbes and contribute to maintaining a healthy intestinal homeostasis. Here, seeking to elucidate whether intestinal epithelial cells modulate Lactobacillus rhamnosus GG (LGG) functions, we examined the production of p40, an LGG-derived secretory protein that protects intestinal epithelial cells against inflammation. We found that growth medium
