Department of Systems Medicine, University of Rome "Tor Vergata", 00133 Rome, Italy.

Celiac disease (CD) is a chronic enteropathy that develops in genetically susceptible individuals after the ingestion of gluten. There has been a substantial increase in CD prevalence in the last 50 years, and it is now estimated that this disease affects approximately 1% of the population in the Western world. In the large majority of cases, CD is a benign disease, characterized by the complete resolution of symptoms and a normal life expectancy after the onset of a gluten-free diet (GFD). Read More

CD1 gene polymorphism and susceptibility to celiac disease: Association of CD1E*02/02 in Moroccans.

Hum Immunol 2020 Jul 25;81(7):361-365. Epub 2020 May 25.

National Research Council (CNR)-Institute of Translational Pharmacology (IFT), L'Aquila, Italy. Electronic address:

CD1 glycoproteins are a class of antigen presenting molecules that bind and present non-peptidic antigens (lipids and glycolipids) for immune recognition. CD1 polymorphisms, although limited, could have a critical role in antimicrobial, anticancer, and autoimmune responses and disease susceptibility. Ethnic differences and interactions between genetic and environmental factors make it attractive the study of these molecules in autoimmune inflammatory disorders, such as celiac disease (CD), in which a strong genetic predisposition (HLA-DQ2/DQ8) and pressure of environmental factors have a central role.

IL-15, gluten and HLA-DQ8 drive tissue destruction in coeliac disease.

Nature 2020 02 12;578(7796):600-604. Epub 2020 Feb 12.

Department of Medicine, University of Chicago, Chicago, IL, USA.

Coeliac disease is a complex, polygenic inflammatory enteropathy caused by exposure to dietary gluten that occurs in a subset of genetically susceptible individuals who express either the HLA-DQ8 or HLA-DQ2 haplotypes. The need to develop non-dietary treatments is now widely recognized, but no pathophysiologically relevant gluten- and HLA-dependent preclinical model exists. Furthermore, although studies in humans have led to major advances in our understanding of the pathogenesis of coeliac disease, the respective roles of disease-predisposing HLA molecules, and of adaptive and innate immunity in the development of tissue damage, have not been directly demonstrated.

Comparison of DNA methylation profiles from saliva in Coeliac disease and non-coeliac disease individuals.

BMC Med Genomics 2020 02 3;13(1):16. Epub 2020 Feb 3.

Western Sydney University, School of Medicine, Sydney, Australia.

Background: Coeliac disease (CD) is a autoimmune disease characterised by mucosal inflammation in the small intestine in response to dietary gluten. Genetic factors play a key role with CD individuals carrying either the HLA-DQ2 or HLA-DQ8 haplotype, however these haplotypes are present in half the general population making them necessary but insufficient to cause CD. Epigenetic modifications, including DNA methylation that can change in response to environmental exposure could help to explain how interactions between genes and environmental factors combine to trigger disease development.

Gut microbiome investigation in celiac disease: from methods to its pathogenetic role.

Clin Chem Lab Med 2020 Feb;58(3):340-349

CEINGE-Biotecnologie Avanzate SCarl, Naples, Italy.

Our body is inhabited by a variety of microbes (microbiota), mainly bacteria, that outnumber our own cells. Until recently, most of what we knew about the human microbiota was based on culture methods, whereas a large part of the microbiota is uncultivable, and consequently previous information was limited. The advent of culture-independent methods and, particularly, of next-generation sequencing (NGS) methodology, marked a turning point in studies of the microbiota in terms of its composition and of the genes encoded by these microbes (microbiome).

Celiac Disease on FDG PET/CT.

Clin Nucl Med 2019 Sep;44(9):e526-e528

From the Barwon Medical Imaging, University Hospital Geelong, Geelong, Victoria, Australia.

An FDG PET with diagnostic CT was performed on a 52-year-old man for investigation of lymphocytosis and the clinical suspicion of lymphoma. The PET/CT demonstrated diffuse small bowel uptake, prominent mesenteric lymph nodes without significant FDG uptake, and other features suggestive of celiac disease. Subsequently, the patient was found to have markedly elevated celiac disease antibodies (deamidated gliadin IgG and tissue transglutaminase IgA) and to be HLA DQ2 and DQ8 allele positive on genotyping for celiac disease.

A Clinician's Guide to Celiac Disease HLA Genetics.

Am J Gastroenterol 2019 10;114(10):1587-1592

Celiac Disease Center, University of Chicago, Chicago, Illinois, USA.

Celiac disease is a common inflammatory disease triggered by dietary gluten in genetically susceptible individuals. The strongest and best-characterized genetic susceptibilities in celiac disease are class II human leukocyte antigen (HLA) genes known as HLA-DQ2 and DQ8. HLA genetic testing is available through a number of commercial and academic laboratories and is used in the evaluation of celiac disease and to identify at-risk family members. Read More

microRNAs: Novel Markers in Diagnostics and Therapeutics of Celiac Disease.

DNA Cell Biol 2019 Jul 13;38(7):708-717. Epub 2019 May 13.

5 Department of Biology, University of Sistan and Baluchestan, Zahedan, Iran.

microRNAs (miRNAs) are a novel class of single-stranded RNAs with a key role in the regulation of gene expression. miRNA main mechanism of action involves interaction with the mRNA transcribed from the genes, leading to the target mRNA silencing and degradation. Indeed, it is easy to conceive that a defective miRNA-based mRNA regulation may compromise normal cell function and cause genetic diseases. Read More

Frequency of HLA celiac disease risk alleles and haplotypes in healthy adults in Tamil Nadu.

Indian J Gastroenterol 2019 04 26;38(2):178-182. Epub 2019 Apr 26.

Institute of Gastroenterology, SRM Institutes for Medical Science, Jawaharlal Nehru Road, Vadapalani, Chennai, 600 026, India.

Celiac disease (CeD) occurs only in individuals who are able to express human leukocyte antigens (HLA) DQ2 or DQ8, and these are expressed in nearly a third of healthy people in the West. As the disease is very uncommon in Tamil Nadu, we evaluated the possibility that the relevant genes are infrequent in this population. Four hundred healthy adults without any gastrointestinal abnormalities were recruited from Vellore district of Tamil Nadu. Read More

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

Aging (Albany NY) 2019 04;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

Targeted genotyping for the prediction of celiac disease autoimmunity development in patients with type 1 diabetes and their family members.

World J Diabetes 2019 Mar;10(3):189-199

Mucosal Immunology and Biology Research Center, Mass General Hospital for Children, Boston, MA 02115, United States.

Background: Patients with type 1 diabetes (T1D) and their first-degree relatives (FDRs) have an increased risk of developing celiac disease (CD) compared to the general population. This is largely explained by the shared association with major histocompatibility class II human leukocyte antigen (HLA) DQ2 and/or DQ8 between the two disease states.

Aim: To describe the frequency of CD autoimmunity (CDA) and the distribution of HLA and haptoglobin genotypes in patients with T1D and their FDRs. Read More
