    Can Aptamers Give Us Better, Faster Gluten Detection?

    Reviewed and edited by a celiac disease expert.

    Celiac.com 07/04/2016 - The fast rising number of people diagnosed with celiac disease creates challenges to both the food industry and public officials to guarantee safe food.

    A great deal of effort is going into determining minimal celiac disease-eliciting doses of gluten and to refine and improve gluten-free labeling.

    Celiac.com Sponsor (A12):
    A team of researchers recently set out to assess the harnessing of aptamers to overcome challenges in gluten detection. The research team included Rebeca Miranda-Castro, Noemí de-los-Santos-Álvarez, Arturo J. Miranda-Ordieres and María Jesús Lobo-Castañón of the Departamento de Química-Física y Analítica, Universidad de Oviedo in Oviedo, Spain.

    Their efforts rely largely on the ability to detect gluten protein in food samples at the lowest levels possible. Current analytical devices use antibodies to determine gluten protein levels. These devices have limited sensitivity, and also have some issues with the accuracy and reliability. Aptamers provide an ideal alternative for designing biosensors that can quickly and reliably measure gluten in foods.

    The team's article highlights the challenges in gluten detection, the current status of the use of aptamers for solving this problem, and what remains to be done to move these systems into commercial applications. They conclude: "The new receptors present high affinity and binding selectivity. In addition, they can be easily labeled with different reporter molecules at a relatively low production cost. These attributes make aptamers ideal reagents for the development of chemical sensors and analytical assays...Although still in its infancy, this sensitive technology will undoubtedly continue to advance."

    Celiac.com 10/15/2012 - The drug ALV003, a potentially promising treatment celiac disease, made by Alvine Pharmaceuticals, Inc., has received Fast Track designation from the U.S. Food and Drug Administration (FDA).
    ALV003 is an orally administered mix of two recombinant gluten-specific proteases, a cysteine protease (EP-B2) and a prolyl endopeptidase (PEP).
    ALV003 works by targeting gluten and breaking it down into tiny fragments, which, in tests has been show to greatly reduce its ability to trigger immune responded in people with celiac disease. ALV003 is being developed as a potential treatment for celiac disease patients in conjunction with a gluten-free diet and is currently in phase 2 clinical development.
    The Fast Track status is important for ALV003, because there are...

    Celiac.com 04/01/2013 - There haven't been many studies that evaluate the usefulness of capsule endoscopy in equivocal celiac disease. A team of researchers recently set out to conduct an evaluation of capsule endoscopy in adult celiac disease, and to assess its potential role in equivocal cases of celiac disease compared with patients with biopsy-proven and serology-proven celiac disease who have persisting symptoms.
    The research team included M. Kurien, K.E. Evans, I. Aziz, R. Sidhu, K. Drew, T.L. Rogers, M.E. McAlindon, and D.S.Sanders. They are affiliated with the Department of Gastroenterology at Royal Hallamshire Hospital, Sheffield Teaching Hospitals NHS Foundation Trust in Sheffield, South Yorkshire, United Kingdom.

    Celiac.com 07/07/2015 - Could proprietary antigen-specific nano-particles offer a potential cure for celiac disease? Early results are very positive, say a team of researchers.
    In what will likely prove to be interesting news for many people with celiac disease, Cour Pharmaceutical Development Company has announced "a significant breakthrough in celiac treatment [that] has the potential to cure celiac patients rather than relying on gluten avoidance, immune suppressive regimens or dietary supplements," according to a company press release.
    According to the release, new data from a pre-clinical live animal study demonstrate a reversal of the effects of dietary gluten exposure in animals sensitized to gluten.
    If true, their use of robust antigen specific nano-particle therapy...

    Celiac.com 03/07/2016 - Even though doctors know a lot more about celiac disease than they did just a few years ago, and even though they are learning more all the time, there are still very few detailed clinical descriptions of large groups of celiac patients.
    Recently, a team of researchers reviewed a large Dutch cohort of celiac patients to create an overview that focused on symptom presentation, co-occurrence of immune mediated diseases and malignancies.
    The research team included M Spijkerman, IL Tan, JJ Kolkman, S Withoff, C Wijmenga, MC Visschedijk, and RK Weersma. They are variously associated with the Department of Gastroenterology and Hepatology, University of Groningen and University Medical Center Groningen, Groningen; the Department of Genetics, University of Groningen...
