INF-α Innate Immune Response to Gliadin

2017-07-19 10:53:22 | BioPortfolio


Background & Aims The enteropathy in Celiac Disease (CD) is due the adaptive and to the innate immune response to gliadin peptides. Gliadin peptide P31-43 activates innate immune response and interferes with vesicular trafficking. Type 1 interferons (INFs) and viral infections play a role in CD pathogenesis. In this paper investigators investigated the role of P31-43 in the activation of the INF-α pathway.

Methods Small intestinal biopsies of CD patients both with active disease on gluten containing diet (GCD) and in remission phase of the disease on a gluten free diet (GFD) and controls were analyzed before and after culture with P31-43. The levels of toll like receptor 7 (TLR7), myeloid differentiation primary response 88 (MyD88), myxovirus resistance protein 1 (MxA) and nuclear factor-κB (NF-κB) proteins and INF-α mRNA was analyzed in intestinal biopsies.


Intestinal biopsies from CD patients and controls were obtained after EGDS performed during routine analysis. The biopsies were immediately immersed in culture medium (Dulbecco's modified medium, DMEM) in a falcon tube and kept for 16h at 37 C before cultivation. Biopsies were cultivated as described in Barone MV1, Caputo I, Ribecco MT, Maglio M, Marzari R, Sblattero D, Troncone R, Auricchio S, Esposito C. Humoral immune response to tissue transglutaminase is related to epithelial cell proliferation in celiac disease. Gastroenterology. 2007,132(4):1245-53.

Medical and Biotech [MESH] Definitions

A malabsorption syndrome that is precipitated by the ingestion of GLUTEN-containing foods, such as wheat, rye, and barley. It is characterized by INFLAMMATION of the SMALL INTESTINE, loss of MICROVILLI structure, failed INTESTINAL ABSORPTION, and MALNUTRITION.

A complex network of nerve fibers including sympathetic and parasympathetic efferents and visceral afferents. The celiac plexus is the largest of the autonomic plexuses and is located in the abdomen surrounding the celiac and superior mesenteric arteries.

A diet which is devoid of GLUTENS from WHEAT; BARLEY; RYE; and other wheat-related varieties. The diet is designed to reduce exposure to those proteins in gluten that trigger INFLAMMATION of the small intestinal mucosa in patients with CELIAC DISEASE.

Simple protein, one of the prolamines, derived from the gluten of wheat, rye, etc. May be separated into 4 discrete electrophoretic fractions. It is the toxic factor associated with CELIAC DISEASE.

Human immune-response, D-related antigen encoded by the D locus on chromosome 6 and found on lymphoid cells. It is in linkage disequilibrium with HLA-A1 and HLA-B8. The HLA-DR3 antigen is strongly associated with celiac disease, Grave's disease, dermatitis herpetiformis, early-age onset myasthenia gravis, systemic lupus erythematosus, juvenile diabetes, and opportunistic infections in AIDS.
