Abstract:
Helicobacter pylori infection is one of the most common bacterial infections worldwide and a major cause of chronic gastritis, peptic ulcers, and gastric cancer. The outer membrane proteins (OMPs) of H. pylori play crucial roles in its pathogenesis, acting as key mediators of bacterial adhesion, immune evasion, and interactions with the host. This review aims to provide a comprehensive overview of the various OMPs involved in H. pylori pathogenesis, including their roles as adhesins, porins, and in biofilm formation. Additionally, this review explores the involvement of OMPs in triggering proinflammatory responses that contribute to the development and progression of severe gastric diseases. By summarizing the current knowledge on H. pylori OMPs, this review highlights their significance as potential targets for therapeutic interventions aimed at preventing or mitigating H. pylori-associated diseases.
Insights
Helicobacter pylori outer membrane proteins (OMPs) are key to infection and disease. Understanding these H. pylori OMPs offers potential therapeutic targets for gastric diseases.
Area of Science:
- Microbiology
- Immunology
- Gastroenterology
Background:
- Helicobacter pylori infection is a global health issue, leading to gastritis, ulcers, and gastric cancer.
- Outer membrane proteins (OMPs) of H. pylori are critical virulence factors.
- OMPs mediate host-bacterial interactions, immune evasion, and adhesion.
Purpose of the Study:
- To provide a comprehensive review of H. pylori OMPs in pathogenesis.
- To elucidate the roles of OMPs in adhesion, porin function, and biofilm formation.
- To explore OMP involvement in host inflammatory responses and disease progression.
Main Methods:
- Literature review of studies on H. pylori outer membrane proteins.
- Analysis of OMP functions including adhesion, porin activity, and biofilm formation.
- Examination of OMP-induced inflammatory pathways in gastric disease.
Main Results:
- H. pylori OMPs are essential for bacterial colonization and survival.
- Specific OMPs function as adhesins, facilitating bacterial attachment to gastric cells.
- OMPs contribute to immune evasion and trigger host inflammatory responses.
Conclusions:
- H. pylori OMPs are central to the development of gastric pathologies.
- Targeting H. pylori OMPs presents a promising strategy for novel therapeutic interventions.
- Further research into OMP functions can guide the development of anti-H. pylori treatments.

Pathophysiology of Peptic Ulcer Disease: Injurious Factors
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
