CHINA – Here’s another reason why you should take your vitamins: A new research report suggests that retinoic acid could be a beneficial treatment for people suffering from ulcerative colitis and other irritable bowel diseases.
Researchers found that retinoic acid, he oxidized form of vitamin A, helps suppress out-of-control inflammation, which is a hallmark of active ulcerative colitis.
“Pharmaceutical strategies based on this research may offer a promising alternative to our current approaches of managing immune diseases including, IBD, arthritis, multiple sclerosis, and so on,” said
To make this discovery, reported in the October print issue of the Journal of Leukocyte Biology, Bai and colleagues conducted in-vitro studies with human tissue and in vivo studies in mice.
Both studies ultimately found that treatment with retinoic acid reduced the inflammation in the colon by increasing the _expression of FOXP3, a gene involved with immune system responses, as well as decreasing the _expression of IL-17, a cytokine believed to cause inflammation. Because many experts believe that IL-17 relates directly to the uncontrolled inflammation seen in ulcerative colitis and irritable bowel disease, the discovery that retinoic acid reduces IL-17’s ability to cause inflammation could accelerate the development of treatments for these chronic diseases.
“Runaway inflammation is serious problem, no matter where it occurs in the body, but in many instances, the root cause is a mystery,” said
