Celiac disease (CD) is an autoimmune disorder induced by the ingestion of gluten in genetically susceptible individualswho carry the HLA-DQ2 or DQ-8 alleles. This disorder affects the small bowel and often leads to villous atrophy, malabsorption,and malignancy. In addition, evidences have indicated that enhanced intestinal permeability is one of the factorsinvolved in the development of various autoimmune disorders as well as CD. It has been proposed that some unfavorable bacteriamay colonize the intestinal mucosa. Presently, adhesion to gluten-free diet is the only effective treatment for the patientsand several researches have indicated the improvement and amelioration of the symptoms. However, exclusion of gluten fromdiet have some constrains for the patients and usually transgressions occur due to the inaccessibility of gluten-free products inmany parts of the world and high price of such products, decrease the quality of life and social pressure. Based on these reasons,alternative therapies including genetically modified gluten, zonulin inhibitors, therapeutic vaccines, tissue transglutaminaseinhibitors, and, recently, probiotics have been proposed. In recent years, probiotics have been assumed to have beneficialeffects on CD management. The beneficial effects of probiotics on the gut health of the host can be revealed through productionof inhibitory substances, blockage of adhesion sites, regulation of immunity, detoxification of toxin receptors and competitionfor nutrients. In CD, the mechanisms of action of probiotics are based on the regulation of microflora composition,influencing the immune system by modulating the innate immune response both to anti-inflammatory and pro-inflammatorydirections. Besides, it has been found that some probiotic strains have hydrolyzing enzymes. In this context, further studiesexploring the efficient bacterial species could expand our knowledge about the exact mechansims involved and assist to designeffective therapeutic approaches of CD.
