BASCUNAN-GAMBOA, Karla A.; ARAYA-QUEZADA, Magdalena  e  PEREZ-BRAVO, Francisco. MicroRNAs: an epigenetic tool to study celiac disease. Rev. esp. enferm. dig. [online]. 2014, vol.106, n.5, pp.325-333. ISSN 1130-0108.

This article summarizes recent findings on the role of microRNAs (miRNAs) in biological processes associated with the regulation of chronic inflammation and autoimmunity. miRNAs are small non-coding RNA molecules that have been recently emerged as a new class of modulators of gene expression at the post-transcriptional level. MiRNAs bind to complementary sequences of specific targets of messengers RNA, which can interfere with protein synthesis. We reviewed studies that evaluated the expression patterns of miRNAs in different autoimmune diseases, especially in celiac disease (CD). CD is a chronic enteropathy triggered by gluten proteins, characterized by altered immune responses in genetically susceptible individuals that results in damage to the bowel mucosa. CD has a high prevalence and an effective treatment by a specific diet ("gluten free diet"). Genetic factors confer susceptibility but do not explain the whole disease, suggesting that environmental factors do play a relevant role in the development of the condition. The evaluation of the potential role of miRNA is of particular interest in CD given that these epigenetic mechanisms in the pathogenesis of autoimmune and inflammatory diseases have been recently described. Improving our understanding of miRNAs in CD will contribute to clarify the role of altered epigenetic regulation in the development and course of this disease.
