Genistein antagonizes gliadin-induced CFTR malfunction in models of celiac disease.

Aging (Albany NY) 2019 Apr;11(7):2003-2019

European Institute for Research in Cystic Fibrosis, San Raffaele Scientific Institute, Milan 20132, Italy.

In celiac disease (CD), an intolerance to dietary gluten/gliadin, antigenic gliadin peptides trigger an HLA-DQ2/DQ8-restricted adaptive Th1 immune response. Epithelial stress, induced by other non-antigenic gliadin peptides, is required for gliadin to become fully immunogenic. We found that cystic-fibrosis-transmembrane-conductance-regulator (CFTR) acts as membrane receptor for gliadin-derived peptide P31-43, as it binds to CFTR and impairs its channel function. Read More

The gliadin-CFTR connection: new perspectives for the treatment of celiac disease.

Ital J Pediatr 2019 Mar 21;45(1):40. Epub 2019 Mar 21.

Equipe11 labellisée Ligue Nationale contrele Cancer, Centre de Recherche des Cordeliers, Paris, France.

Familial loss-of-function mutations of the gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) channel protein cause cystic fibrosis (CF), the most frequent inherited life-threatening disease in the Caucasian population. A recent study indicates that the gluten/gliadin-derived peptide (P31-43) can cause CFTR inhibition in intestinal epithelial cells, thus causing a local stress response that contributes to the immunopathology of celiac disease (CD). Accordingly, an increased prevalence of CD has been observed in several cohorts of CF patients. Read More

High rates of variation in HLA-DQ2/DQ8 testing for coeliac disease: results from an RCPAQAP pilot program.

J Clin Pathol 2018 Oct 15;71(10):900-905. Epub 2018 May 15.

RCPAQAP Molecular Genetics, St. Leonard's, Sydney, New South Wales, Australia.

Aim: Coeliac disease(CD) is a highly prevalent, gluten-dependent, autoimmune enteropathy. While the diagnosis is based on serological and histological criteria, genotyping of the human leucocyte antigens (HLA) DQ2 and DQ8 has been shown to have substantial clinical utility, especially in excluding the diagnosis in patients who do not carry either antigen. As a result, HLA genotyping is now being performed by more laboratories and has recently become one of the most frequently requested genetic tests in Australia. Read More

Daily Intake of Milk Powder and Risk of Celiac Disease in Early Childhood: A Nested Case-Control Study.

Nutrients 2018 Apr 28;10(5). Epub 2018 Apr 28.

The Diabetes and Celiac Disease Unit, Department of Clinical Sciences, Lund University, 202 05 Malmö, Sweden.

Milk powder and gluten are common components in Swedish infants' diets. Whereas large intakes of gluten early in life increases the risk of celiac disease in genetically at-risk Swedish children, no study has yet evaluated if intake of milk powder by 2 years of age is associated with celiac disease. A 1-to-3 nested case-control study, comprised of 207 celiac disease children and 621 controls matched for sex, birth year, and HLA genotype, was performed on a birth cohort of HLA-DR3-DQ2 and/or DR4-DQ8-positive children.

Role of Human Leukocyte Antigens (HLA) in Autoimmune Diseases.

Rheumatol Ther 2018 Jun 7;5(1):5-20. Epub 2018 Mar 7.

Division of Rheumatology and Clinical Immunology, University Hospital, Mainz, Germany.

Since the discovery of HLA 60 years ago, it has contributed to the understanding of the immune system as well as of the pathogenesis of several diseases. Aside from its essential role in determining donor-recipient immune compatibility in organ transplantation, HLA genotyping is meanwhile performed routinely as part of the diagnostic work-up of certain autoimmune diseases. Considering the ability of HLA to influence thymic selection as well as peripheral anergy of T cells, its role in the pathogenesis of autoimmunity is understandable. Read More

Profiling Celiac Disease-Related Transcriptional Changes.

Int Rev Cell Mol Biol 2018 18;336:149-174. Epub 2017 Sep 18.

University of the Basque Country (UPV/EHU), BioCruces Health Research Institute, Leioa, Basque Country, Spain. Electronic address:

Celiac disease (CD) is a chronic, autoimmune disease of the small intestine with a strong but complex genetic component. The disease is triggered by the consumption of dietary gluten through the presentation of immunogenic gliadin peptides to T helper lymphocytes by HLA-DQ2 and DQ8 heterodimers, which are the major contributors to the genetic risk. Recent large-scale genotyping efforts have identified a large number of additional association signals, but the functional role of the underlying genes in the pathogenesis of the disease is still unclear.
