Nonpathogenic Lactobacillus rhamnosus activates the inflammasome and antiviral responses in human macrophages

In this study, we have utilized global gene expression profiling to compare the responses of human primary macrophages to two closely related, well-characterized Lactobacillus rhamnosus strains GG and LC705, since our understanding of the responses elicited by nonpathogenic bacteria in human innate immune system is limited. Macrophages are phagocytic cells of the innate immune system that perform sentinel functions to initiate appropriate...
