This $828,820 Project Grant award from the National Institute of Allergy and Infectious Diseases (NIAID) under the Allergy and Infectious Diseases Research program (CFDA 93.855) supports research to investigate the molecular mechanisms by which the commensal bacterium Enterococcus faecalis transitions from a gut resident to a pathogen that can breach the intestinal barrier and cause systemic infections. The key objectives are to: 1) define how E. faecalis disrupts endoplasmic reticulum (ER) proteostasis in epithelial cells, 2) establish that E. faecalis-induced ER stress responses compromise intestinal barrier function, and 3) test if disabling ER stress sensors in vivo can thwart enterococcal translocation during antibiotic-induced dysbiosis. The research will leverage the multidisciplinary expertise of the award recipients at Weill Medical College of Cornell University in E. faecalis pathogenesis, ER stress biology, and intestinal physiology. The findings could lead to new treatments to prevent or control systemic infections caused by gut-resident enterococci.
