[Celiac disease. New therapeutic alternatives based on a better knowledge of molecular pathogenesis].

Coeliac disease is a chronic autoimmune-like gastrointestinal disorder triggered by a known exogenous antigen (gluten). The disease is strongly linked to the HLA system, though other genetic, environmental and immunologic factors, may determine the type and timing of presentation. The immune response within the intestinal mucosa is characterized by a well defined TH1 response, where IFNgamma secreted by specific T cells is the predominant cytokine, as well as an innate immune response to certain gluten-derived peptides, mediated by IL-15. The strict gluten-exclusion diet is the best way of reversing both the symptoms and the histological changes in the intestinal mucosa. However, the frequency of transgressions and a low dietary compliance had led to the description of new therapeutic alternatives discussed in this review.
