Gpbar1 (TGR5), a membrane-bound bile acid receptor, is well-known for its roles in regulation of energy homeostasis and glucose metabolism. Here, we show that mice lacking TGR5 were much more susceptible to lipopolysaccharide (LPS)-induced acute gastric inflammation than wild-type (WT) mice and TGR5 is a negative regulator of gastric inflammation through antagonizing NF-κB signaling pathway. We...
Persistent colonization of the gastric mucosa by Helicobacter pylori (Hp) elicits chronic inflammation and aberrant epithelial cell proliferation, which increases the risk of gastric cancer. Here we examine the ability of microRNAs to modulate gastric cell proliferation in response to persistent Hp infection and find that epigenetic silencing of miR-210 plays a key role in gastric disease progr...
The features of Helicobacter pylori adhesins, their interactions with their host counterparts, regulated and selective gene expressions are amongst the many clever strategies this microorganism undertakes to survive the otherwise sterile gastric milieu. The ingenious crafting of these interactions and the respective host reactions govern, in part, an array of consequences ranging from asympto...
Th17-driven immune responses contribute to the pathogenesis of many chronic inflammatory diseases. In this study, we investigated the role of IL-17 signaling in chronic gastric inflammation induced by Helicobacter pylori, a Gram-negative bacterium that persistently colonizes the human stomach. Wild-type C57BL/6 mice and mice lacking IL-17RA (IL-17RA(-/-)) were orogastrically infected with H. py...
PURPOSE Helicobacter pylori infection in children is associated with a chronic inflammatory process of gastric and duodenal mucosa, which may have a various clinical course ranging from asymptomatic and chronic inflammatory condition to gastric ulceration. The immune system may contribute especially to chronic gastric mucosa inflammation. The aim of our study was to assess the levels of periphe...
OBJECTIVES In this study, we analysed the expression of chitotriosidase (CHIT1) and acidic mammalian chitinase (AMCase) genes in human gastric mucosa biopsies to establish the function of the corresponding enzymes in patients with gastritis associated or not with Helicobacter pylori infection. METHODS All 27 patients who took part in this study suffered from dyspeptic symptoms and postprandia...
PURPOSE Helicobacter pylori colonization of gastric epithelium causes a local and systemic, cellular and humoral immune response. Despite this immune response involvement in the infection, its elimination from the organism does not take place and the process usually becomes chronic. The purpose of the study was to establish the prevalence of gastric mucosa inflammation in children and adults wi...
helicobacter pylori is an important human pathogen and a gram-negative, spiral shaped and microaerophilic bacteria with persistence colonization in gastric mucosa, causes gastroduodenal inflammation and destruction, resulting in diseases such as duodenal ulcer disease, gastric ulcer disease. when h.pylori discovered by warren and marshall, effective therapy developed for this infection and resu...
