    Could Enzymes from Oral Bacteria Treat Celiac Disease?

    Celiac.com 10/21/2016 - Researchers at Boston University's Henry M. Golden School of Dental Medicine have identified a metabolic enzyme that alerts the body to invading bacteria, which may lead to new treatments for celiac disease.

    A research team that set out to isolate and identify the enzymes and evaluate their potential as novel enzyme therapeutics for celiac disease, reports that the enzymes exhibit exceptionally high gluten-degrading enzyme activities, and are "naturally associated with bacteria that colonize the oral cavity."

    Celiac.com Sponsor (A12):
    Rothia bacteria, found in human saliva, can break down gluten compounds that cause an exaggerated immune response and that are typically resistant to the digestive enzymes that mammals produce. The team was able to isolate a new class of gluten-degrading enzymes from Rothia mucilaginosa, an oral microbial colonizer. The Rothia enzymes in question belong to the same class as food-grade Bacillus enzymes. The researchers noted that "B. subtilis is food safe and has been consumed for decades, e.g. in a product called natto, a Japanese fermented soy bean dish."

    B. subtilis and its products have been safely consumed by humans for many hundreds of years, with very few problems reported. They add that the "…food-grade status of B. subtilis, and the already widely consumed natto products, open new avenues for potential therapeutic applications of the subtilisin enzymes."

    The Rothia subtilisins and two subtilisins from Bacillus licheniformis, subtilisin A and the food-grade Nattokinase, efficiently degraded the immunogenic gliadin-derived 33-mer peptide and the immunodominant epitopes recognized by the R5 and G12 antibodies. This study identified as promising new candidates for enzyme therapeutics in celiac disease.

    Based on these results, the research team concludes that gluten-degrading Rothia and food-grade Bacillus subtilisins are the "preferred therapy of choice for celiac disease," and that their exceptional enzymatic activity, along with their connection to natural human microbial colonizers, make them "worthy of further exploration for clinical applications in celiac disease and potentially other gluten-intolerance disorders."

    Celiac.com 04/04/2016 - Any one eager to try the first approved treatment for celiac disease might not have to wait much longer.
    Alba Therapeutics has announced that their celiac treatment, larazotide acetate, will enter the first Phase 3 clinical trials ever conducted in a celiac disease drug later this year.
    Lorazotide acetate works by improving regulation of tight junctions in the bowel. In healthy people, these junctions remain closed except to shed dead cells, but in patients with celiac disease, gluten keeps tight junctions open, triggering an inflammatory reaction that eventually destroys the intestinal villi, tiny, finger-like projections in the small intestine that are essential for nutrient absorption.
    Early research suggests larazotide acetate helps to keep the tight...

    Celiac.com 08/05/2016 - Currently, a gluten free diet is the only option for treating celiac disease. Still, there are numerous patients who follow the diet, but do not respond fully clinically or histologically.
    What options do doctors have to treat celiac disease beyond a gluten-free diet? A team of researchers wanted to find out. The research team includes S. Kurada, A. Yadav, and DA Leffler of the Division of Gastroenterology, Department of Medicine, Beth Israel Deaconess Medical Center, and the Celiac Research Program at Harvard Medical School, and the Department of Medicine at Boston Medical Center’s Boston University School of Medicine in Boston, Massachusetts.
    The team conducted a search of PubMed and Open Original Shared Link to highlight celiac disease articles that u...

    Celiac.com 07/25/2016 - Celiac disease is one of the most common immune-mediated diseases. Often, a gluten-free diet does not fully control celiac symptoms and disease activity.
    Even though no new therapies have been approved, a growing effort, coupled with a rapidly expanding knowledge of the regulatory pathway could soon lead to new breakthroughs.
    A team of researchers recently reviewed the epidemiology, pathophysiology, and current treatment paradigm for celiac disease. The researchers were M Wungjiranirun, CP Kelly, and DA Leffler, both of the Division of Gastroenterology at the Celiac Center of Beth Israel Deaconess Medical Center in Boston, Massachusetts, USA.
    They also reviewed the major types of therapies being proposed for celiac treatment, and expounded broadly upon...

    Celiac.com 07/19/2016 - The world's first vaccine aimed at curing celiac disease is slated to begin full trials later this year, and residents of the Australian state of Victoria will be among the first humans to give it a try against celiac disease.
    The vaccine, called Nexvax2, was developed by Australian scientist Dr Bob Anderson, and is aimed at giving celiac patients a chance to overcome their immune reaction to the gluten found in products containing wheat, rye and barley. Nexvax2 aims to de-sensitise patients to three peptides contained in gluten that trigger a damaging reaction in their immune system.
    Previous trials on 150 patients from Melbourne, Perth, Adelaide, Brisbane and Auckland were aimed at finding a safe dosage rather than assessing its ability to beat celiac disease...
