Pseudomonas fluorescens Alters the Intestinal Barrier Function by Modulating IL-1β Expression Through Hematopoietic NOD2 Signaling

Abstract

Pseudomonas fluorescens thus alters the homeostasis of the epithelial barrier function by a mechanism similar to that previously observed for Yersinia pseudotuberculosis. This work further documents a putative role of psychrotrophic bacteria in Crohn's disease.
