Colonization of the gastric mucosa with Helicobacter pylori (Hp) leads to the cascade of pathologic events including local inflammation, gastric ulceration, and adenocarcinoma formation. Paracrine loops between tissue cells and Hp contribute to the formation of gastric cancerous loci; however, the specific mechanisms underlying existence of these loops remain unknown. We determined the phenotypic properties of gastric fibroblasts exposed to Hp (cagA+vacA+) infection and their influence on normal epithelial RGM-1 cells.

Helicobacter pylori colonizes the human gastric mucosa, causing chronic inflammation, peptic ulcers and gastric cancer. A cascade of harmful processes results from the interaction of these bacteria wi...
Gastric acid secretion is compromised in chronic Helicobacter pylori (H. pylori) infection allowing overgrowth of non-H. pylori gastric bacteria (NHGB) in the stomach.
The Helicobacter pylori (H. pylori) cytotoxin-associated gene A (CagA) and Krüppel-like transcription factor (KLF4) were both closely associated with the development and progression of gastric cancer...
Helicobacter pylori (H pylori) infection is closely associated with the incidence of gastric cancer. However, whether H pylori eradication prevents metachronous gastric cancer remains uncertain. The a...
Helicobacter pylori (H pylori) is the main risk factor for gastric cancer (GC). In recent years, many studies have addressed the effects of H pylori itself and of H pylori-induced chronic inflammatio...
Helicobacter pylori (H. pylori) infection, affecting an estimated 50% of the global population, is a main cause of chronic gastritis, peptic ulcers and gastric cancer. By causing progressi...
There are controversies about the best sites -biopsy based -tests for H pylori associated gastritis. The study is designed to evaluate the optimal site of gastric mucosal biopsy for identi...
Helicobacter pylori plays an important role in the development of gastric cancer, while other gastric microbiota may also involved. Is there some difference of the gastric microbiota befor...
Helicobacter pylori is closely related with gastritis, peptic ulcer, gastric cancer and gastric MALT lymphoma, and it may participate in a variety of parenteral diseases. Infection rates o...
Helicobacter pylori (HP) is the major risk factors of gastritis, gastric ulcers, duodenal ulcers, mucosa associated lymphoid tissue lymphoma and gastric cancer. Helicobacter pylori are fou...
A spiral bacterium active as a human gastric pathogen. It is a gram-negative, urease-positive, curved or slightly spiral organism initially isolated in 1982 from patients with lesions of gastritis or peptic ulcers in Western Australia. Helicobacter pylori was originally classified in the genus CAMPYLOBACTER, but RNA sequencing, cellular fatty acid profiles, growth patterns, and other taxonomic characteristics indicate that the micro-organism should be included in the genus HELICOBACTER. It has been officially transferred to Helicobacter gen. nov. (see Int J Syst Bacteriol 1989 Oct;39(4):297-405).
Infections with organisms of the genus HELICOBACTER, particularly, in humans, HELICOBACTER PYLORI. The clinical manifestations are focused in the stomach, usually the gastric mucosa and antrum, and the upper duodenum. This infection plays a major role in the pathogenesis of type B gastritis and peptic ulcer disease.
A species of gram-negative, spiral-shaped bacteria found in the gastric mucosa that is associated with chronic antral gastritis. This bacterium was first discovered in samples removed at endoscopy from patients investigated for HELICOBACTER PYLORI colonization.
Ulceration of the GASTRIC MUCOSA due to contact with GASTRIC JUICE. It is often associated with HELICOBACTER PYLORI infection or consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).
Ulcer that occurs in the regions of the GASTROINTESTINAL TRACT which come into contact with GASTRIC JUICE containing PEPSIN and GASTRIC ACID. It occurs when there are defects in the MUCOSA barrier. The common forms of peptic ulcers are associated with HELICOBACTER PYLORI and the consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).
Peptic Ulcer Disease
Peptic Ulcer Disease - stomach ulcer, duodenal ulcers used to refer to all types of peptic ulcers. A peptic ulcer is an erosion in a segment of the Gastrointestinal (GI) muscularis mucosae, typically in the stomach (gastric ulcer) or the first few cent...
