Celiac disease is a chronic immune-mediated enteropathy that may be unleashed by enteric viral infections. However, new findings in mice identified a commensal protist, Tritrichomonas arnold, that protects against reovirus-induced intolerance to gluten by counteracting virus-induced proinflammatory dendritic cell activation.

While celiac disease affects predominantly the small intestine, the contribution of the small intestinal microbiota has been largely understudied. New findings characterize the duodenal microbiota in patients with active celiac disease and explores its functional relevance.

Analysing the molecular and biochemical mechanisms disturbing the complex network of communication is key to our understanding of the pathophysiology of the functional GI disorders. Together with ESNM we have prepared an exciting webinar series under the topic: Microbiota and Gut-Brain Connection: A new Frontier in Neurogastroenterology. This free resource is a great opportunity to hear leading worldwide experts presenting the most recent findings on this topic.

Genetic predisposition alone cannot fully explain the current rise of food sensitivities, like celiac disease. Scientists have characterized the bacterial enzyme elastase involved in driving immune activation and worsening reactions to gluten in genetically susceptible hosts.
