Regarding immunity, vitamin A contributes to supporting the integrity of epithelia, particularly 5A). Vitamin C plays an important role in many of our body functions like strengthening the immune system, absorbing iron, maintaining collagen, maintaining strong bones and others. Previous studies have suggested a link between vitamin D deficiency and IBD risk (23). | Managing osteoporosis in ulcerative colitis: Something new? 8-9, Research in Veterinary Science, Vol. 8, No. 4, No. Further studies should confirm whether vitamin D/VDR is beneficial for the prevention or treatment of lung diseases. 24, No. 5, 30 June 2016 | Annals of the New York Academy of Sciences, Vol. To our knowledge the role of vitamin D/VDR in intestinal barrier homeostasis has not been reported. This observation suggests that vitamin D may stimulate epithelial restitution in mucosal wound healing. It remains to be determined whether the DSS susceptibility is entirely caused by the loss of VDR in the epithelial compartment. Maternal/neonatal vitamin D deficiency: a new risk factor for necrotizing enterocolitis in preterm infants? 4A). Would you like email updates of new search results? TER is an indication of epithelial barrier integrity, as decreased epithelial barrier function is accompanied by a reduction in TER. The objective of this application is to study special consequences of VDR deficiency in Paneth cells and dysbiosis in the inflamed states. B vitamins and vitamin C, however, play particularly valuable roles in digestive health, says Dr. Chris Iliades, a physician and contributing health writer for EveryDayHealth.com. Europe PMC. Indeed, in VDR+/+ mice, after DSS treatment was stopped, epithelial restitution, proliferation, and new crypt formation were clearly seen in the ulcerated lesions. Table 1. VDR+/+ mice were treated with 2.5% DSS for 7 days, and the colon was harvested 8 days after the DSS treatment was stopped. 12, 13 November 2013 | Gastroenterology Report, Vol. 4, Current Opinion in Gastroenterology, Vol. VDR knockdown with small interfering (si)RNA reduced the junction proteins and TER in Caco-2 monolayers. 20, No. The vitamin that plays a role in maintaining epithelia and is required for the synthesis of visual pigmentsis vitamin A) A.
