A266 AMYLASE TRYPSIN INHIBITORS FROM WHEAT EXACERBATE GLUTEN-INDUCED PATHOLOGY AND ALTER GUT MICROBIOTA IN MICE
2018
BACKGROUND: Celiac disease (CeD) is an autoimmune enteropathy triggered by gluten in genetically susceptible individuals expressing HLA DQ2 or DQ8. The adaptive immune response is characterized by a gluten-specific T-cells, anti-gluten and anti-tissue transglutaminase-2 antibodies. Proliferation and activation of intraepithelial lymphocytes (IELs) is central to the innate immune response, although the triggers and receptors remain unclear. Amylase trypsin inhibitors (ATIs) are pest-resistant molecules in modern wheat with TLR4-activating capacities in mononuclear phagocytic cells. AIMS: Our aim was to determine whether ATIs act as innate activators, enhancing gluten immunopathology in mice.…
A49 LACTOBACILLI DEGRADE WHEAT AMYLASE TRYPSIN INHIBITORS (ATI) TO AMELIORATE GUT DYSFUNCTION INDUCED BY IMMUNOGENIC WHEAT PROTEINS
2019
BACKGROUND: Wheat-related disorders involve a wide spectrum of conditions, triggered by the ingestion of gluten-containing cereals. The induction of gluten-specific immune responses in celiac disease is well established. However, the contribution of gluten and/or non-gluten proteins in the generation of symptoms in other wheat-related disorders is controversial. Amylase trypsin inhibitors (ATIs) are pest-resistant molecules in modern wheat with TLR4-activating capacities. AIMS: We investigated the role of ATIs in the generation of gut barrier dysfunction and dysmotility in wild-type mice as well as in the severity of gluten-induced immunopathology in genetically predisposed mice. We also de…
