Helicobacter pylori is a major etiological agent in gastroduodenal disorders. H. pylori adhesion to human gastric mucosa is the initial step of H. pylori colonization. Inhibition of H. pylori adhesion is thus a therapeutic target in preventing H. pylori infection. We have previously established a method using the enzyme-linked immunosorbent assay to analyze quantitatively H. pylori adhesion to gastric epithelial cells. This method is suitable for screening antiadhesion agents. Some mucoprotective agents are proved to have antiadhesion effects in vitro, and they may modify H. pylori adhesion. This evidence gives us a useful clue to analyze the molecular mechanism of H. pylori adhesion to mucosa. Furthermore, in clinical trials, these mucoprotective agents enhanced the eradication rate when administered with antibiotics. In conclusion, the antiadhesion agents may have potential as therapeutic regimens against H. pylori infection.

UI MeSH Term Description Entries
D005753 Gastric Mucosa Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.

D001422 Bacterial Adhesion Physicochemical property of fimbriated (FIMBRIAE, BACTERIAL) and non-fimbriated bacteria of attaching to cells, tissue, and nonbiological surfaces. It is a factor in bacterial colonization and pathogenicity. Adhesion, Bacterial,Adhesions, Bacterial,Bacterial Adhesions
D016480 Helicobacter pylori 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).
