Gut Vitamin D Receptors and Flora

"The findings deliver a new lead to scientists investigating how bacteria might play a role in the development of inflammatory bowel diseases such as Crohn's disease or ulceractive colitis. The work complements studies suggesting that Salmonella infection can increase the risk of inflammatory bowel disease.

"Vitamin D deficiency is a known factor in the pathology of inflammatory bowel disease and colon cancer," said microbiologist Jun Sun, Ph.D., of the University of Rochester Medical Center, "but there have been very few reports about how bacteria might play a role by targeting the vitamin D receptor. Our work suggests one possible mechanism, by working through the vitamin D receptor, a sensor and regulator for the majority of functions of vitamin D.""

Amid the murk of 'gut flora,' vitamin D receptor emerges as a key player
