Lactobacillus Rhamnosus GG Treatment Improves Intestinal Permeability and Modulates Inflammatory Response and Homeostasis of Spleen and Colon in Experimental Model of Pseudomonas Aeruginosa Pneumonia

摘要

Background and AimsRecent clinical trials and in vivo models demonstrate probiotic administration can reduce occurrence and improve outcome of pneumonia and sepsis, both major clinical challenges worldwide. Potential probiotic benefits include maintenance of gut epithelial barrier homeostasis and prevention of downstream organ dysfunction due to systemic inflammation. However, mechanism(s) of probiotic-mediated protection against pneumonia remain poorly understood. This study evaluated potential mechanistic targets in the maintenance of gut barrier homeostasis following Lactobacillus rhamnosus GG (LGG) treatment in a mouse model of pneumonia.
