    Study Hints at Connection Between Celiac Disease and Certain Viral Infections

    Celiac.com 07/28/2016 - Celiac disease is an immune-mediated enteropathy triggered by gluten in genetically susceptible individuals. Researchers know that innate immunity plays a role in triggering celiac disease, but they don't understand the connection very well at all.

    Although previous in vitro work suggests that gliadin peptide p31-43 acts as an innate immune trigger, the underlying pathways are unclear and have not been explored in vivo.

    The research team included RE Araya, MF Gomez Castro, P Carasi, JL McCarville, J Jury, AM Mowat, EF Verdu, and FG Chirdo. They are variously affiliated with the Instituto de Estudios Inmunológicos y Fisiopatológicos (IIFP)(CONICET-UNLP), Facultad de Ciencias Exactas, Universidad Nacional de La Plata, La Plata, Argentina; the Catedra de Microbiología, Facultad de Ciencias Exactas, Universidad Nacional de La Plata, La Plata, Argentina; the Farncombe Family Digestive Health Research Institute, McMaster University, Hamilton, Ontario, Canada; the Centre for Immunobiology, Institute of Infection, Immunity and Inflammation, University of Glasgow, Glasgow, Scotland, United Kingdom; and with the Instituto de Estudios Inmunológicos y Fisiopatológicos (IIFP)(CONICET-UNLP), Facultad de Ciencias Exactas, Universidad Nacional de La Plata, La Plata, Argentina.

    Their team observed that introduction of p31-43 into the gut of normal mice causes structural changes in the small intestinal mucosa consistent with those seen in celiac disease, including increased cell death and expression of inflammatory mediators. The effects of p31-43 were dependent on MyD88 and type I IFNs, but not Toll-like receptor 4 (TLR4), and were enhanced by co-administration of the TLR3 agonist polyinosinic:polycytidylic acid.

    Together, these results indicate that gliadin peptide p31-43 activates celiac-related innate immune pathways in vivo, such as IFN-dependent inflammation.

    These findings also suggest a common mechanism for the potential interaction between dietary gluten and viral infections in the pathogenesis of celiac disease, meaning that certain viral infections may pave the way for celiac disease to develop.

    Duh!!!! My celiac disease was turned on when I was exposed to a virus my boss (he refused to stay home when he was running a fever and coughing violently) that had infected me and became double pneumonia. Once the virus had run it's course, in about two weeks, I had my first experience with celiac disease. My adult daughter 8 months later was diagnosed with celiac disease after exposure with a kidney infection. Her young son was diagnosed with celiac disease after exposure to bad virus. Definitely a pattern here!

    Can a virus affect a "genetic" celiac diagnosis? If a genetic diagnosis is given does that mean both parents carry the gene at same time or only parent parent? Or is it a recessive gene from both parents. Or is this still unknown?

    Immune system trauma from infections seems to be a common trigger of autoimmune diseases (like mine) according to my doctor. Genetic markers are unknown for most diseases so...

    I have an autoimmune disease (not celiac) that directly coincided with probably the worst viral infection (strep) I've ever had. My doctors say they have no reason to speculate whether the infection triggered the autoimmune disease since treatments are the same and there's not much is known about possible triggers. It seems that compromised immune systems, no matter the severity or duration, are increasingly being linked to development of diseases. The biggest research hospitals say there's definitely a link but still don't know exactly how the process happens. It's easy to see that unhealthy people are more susceptible to infections and diseases. Think of: diabetics, smokers, alcoholics, obese, those exposed to toxins, etc.
