Circulating microRNAs Suggest Networks Associated with Biological Functions in Aggressive Refractory Type 2 Celiac Disease.

Biomedicines 2022 Jun 14;10(6). Epub 2022 Jun 14.

Department of Biomedical, Surgical and Dental Sciences, University of Milan, Street Pascal 36, 20133 Milan, Italy.

Despite following a gluten-free diet, which is currently the only effective therapy for celiac disease, about 5% of patients can develop serious complications, which in the case of refractory type 2 could evolve towards intestinal lymphoma. In this study, we have identified a set of 15 microRNAs in serum discriminating between the two types of refractory disease. Upregulated miR-770-5p, miR-181b-2-3p, miR-1193, and miR-1226-3p could be useful for the better stratification of patients and the monitoring of disease development, while miR-490-3p was found to be dysregulated in patients with refractory type 1.

Recognizing the Emergent and Submerged Iceberg of the Celiac Disease: ITAMA Project-Global Strategy Protocol.

Pediatr Rep 2022 Jun 10;14(2):293-311. Epub 2022 Jun 10.

Dipartimento di Matematica e Informatica, Università di Palermo, 90133 Palermo, Italy.

Coeliac disease (CD) is frequently underdiagnosed with a consequent heavy burden in terms of morbidity and health care costs. Diagnosis of CD is based on the evaluation of symptoms and anti-transglutaminase antibodies IgA (TGA-IgA) levels, with values above a tenfold increase being the basis of the biopsy-free diagnostic approach suggested by present guidelines. This study showcased the largest screening project for CD carried out to date in school children (n=20,000) aimed at assessing the diagnostic accuracy of minimally invasive finger prick point-of-care tests (POCT) which, combined with conventional celiac serology and the aid of an artificial intelligence-based system, may eliminate the need for intestinal biopsy.

Effect of extrusion on the modification of wheat flour proteins related to celiac disease.

J Food Sci Technol 2022 Jul 11;59(7):2655-2665. Epub 2021 Oct 11.

State Key Laboratory of Food Science and Technology, Nanchang University, Nanchang, 330047 People's Republic of China.

Wheat flour was extruded using a single- and double-screw extruder at 130, 150, and 170 °C, respectively, to determine the effect of extrusion on the content and possible modifications of protein in wheat flour. Regarding to proteins, their yield under non-reducing extraction conditions (in SDS only) decreased to one-third after extrusion-but remained constant after extraction under reduced conditions (in SDS + DTT). This phenomenon possibly reflected protein cross-linking through intermolecular disulfide bonds to gluten proteins, especially at high temperature and high screw speed during double-screw extrusion, as suggested by the increased number of free-SH-groups and reduced intensity of low-MW proteins in SDS-PAGE under this extrusion condition.

The Association of Inflammatory Gut Diseases with Neuroinflammatory and Auditory Disorders.

Front Biosci (Elite Ed) 2022 Mar;14(2)

Department of Physiology and The Eisdell Moore Centre, Faculty of Medical and Health Sciences, The University of Auckland, Private Bag, 1142 Auckland, New Zealand.

Disorders such as inflammatory bowel disease (IBD) and celiac disease (CeD) result in intestinal hyperpermeability or 'leaky' gut. The increased permeability of the intestinal barrier allows microbial metabolites, toxins, and pathogens to infiltrate the bloodstream and extraintestinal tissues, causing systemic inflammation. Despite differences in aetiology and pathophysiology, IBD and CeD share several extraintestinal manifestations such as neuroinflammation, neurological and psychiatric manifestations, and sensorineural hearing loss (SNHL).

Transglutaminase 2 affinity and enzyme-substrate intermediate stability as determining factors for T-cell responses to gluten peptides in celiac disease.

Eur J Immunol 2022 Jun 17. Epub 2022 Jun 17.

KG Jebsen Coeliac Disease Research Centre, Institute of Clinical Medicine, University of Oslo, Oslo, Norway.

The adaptive immune response of celiac disease (CeD) involves presentation of gluten peptides to CD4+ T cells by transglutaminase 2 (TG2) specific B cells. This B-cell/T-cell crosstalk is facilitated by involvement of TG2:gluten peptide complexes that act principally in the form of enzyme-substrate intermediates. Here, we have addressed how gluten peptide affinity and complex stability in the presence of secondary substrates affect the uptake of TG2:gluten peptide complexes by TG2-specific B cells and the activation of gluten-specific T cells.
