Celiac.com 07/01/2006 - With the likelihood that increased intestinal permeability in celiacs caused by gluten damage to the intestinal mucosa leads to a high prevalance of liver damage as well as an increase in food allergy and possible other medical conditions, emphasis on healing the intestinal mucosa should be given an elevated priority. Simply going on a gluten-free diet and waiting months or years for the intestine to heal may not be enough.
Friendly commensal gut bacteria are an important part
of the intestinal barrier, and thus probiotics, such as yogurt, kefir,
probiotic capsules, do help diminish the amount of endotoxins released by pathogenic gut bacteria getting through the barrier. Liver disease studies confirm the benefit of probiotics by reducing inflammation and infection. However, to date, there is no product currently available which can enhance the repair and regeneration process of the mucosal epithelia.
Undergoing current clinical studies in Crohns
patients, Teduglutide may enhance mucosal healing, but requires multiple

A while back I posted an abstract about a protein called
R-spondin1 which is "a specific and potent stimulator of the human
epithelial cells that line the gastrointestinal tract and mouth."
R-spondin1 is a product being developed by Nuvelo, Inc. of San Carlos,
CA designated as NU206. The press release describing NU206 is:
Nuvelo Announces NU206 Publication in Science (August 18, 2005)
An article discussing the discovery and potentials of
R-spondin1 is available in the New England Journal of Medicine, and free

Nuvelo has recently announced plans for the "initiation of a Phase 1 study of NU206, which is being developed for the treatment of cancer therapy-induced mucositis in the second half of 2006." Obviously the benefits of NU206 go beyond that of cancer therapy. Healing the epithelial tissues of celiacs with NU206 may rapidly eliminate increased intestinal permeability and other associated conditions. Nuvelo had a live webcast of its annual shareholder meeting this Wednesday, May 24, at 11:00 am PDT. No new information on NU206 was provided at the meeting other than that plans to initiate the NU206 Phase 1 study are proceding.
