Dr. Khoruts has trained at the University of Minnesota. In addition to completing his fellowship in gastroenterology, he also trained in basic immunology as a Howard Hughes Physician Fellow under the mentorship of Dr. Marc Jenkins in the Department of Microbiology. He continued his early research focus on basic biology of T cells and autoimmunity, but more recently has redirected his efforts into areas of microbiota therapeutics.
Gut microbiota (commensal microbial communities) is integral to the function of the digestive system and entire body physiology. Disruption of gut microbiota by antibiotics can make the body vulnerable to infections like Clostridium difficile. In addition, gut microbiota likely plays important roles in inflammatory bowel disease, development of the immune system, disorders of energy metabolism like diabetes, and gastrointestinal cancer.
Dr. Khoruts is the Medical Director of the University of Minnesota Microbiota Therapeutics Program. This program brings together multiple investigators from across the Medical School and the University. The primary clinical function at this time is treatment of patients with refractory C. difficile infection. However, additional investigational work is ongoing in metabolic syndrome, gastrointestinal malignancies in cystic fibrosis, blood and marrow transplantation, and inflammatory bowel disease.
