Review article: rebamipide and the digestive epithelial barrier

Area of Science:

• Gastroenterology
• Immunology
• Pharmacology

Background:

• The digestive epithelial barrier is crucial for gut health.
• Helicobacter pylori infection can compromise this barrier.
• Allergic sensitization and impaired oral tolerance are significant health concerns.

Purpose of the Study:

• To investigate the effects of rebamipide on the digestive epithelial barrier.
• To evaluate rebamipide's impact on allergic sensitization and oral tolerance.
• To understand rebamipide's anti-inflammatory mechanisms in the digestive tract.

Main Methods:

• Assessing epithelial barrier integrity in vitro and in vivo.
• Measuring macromolecular transport across the barrier.
• Evaluating allergic sensitization and oral tolerance in a mouse model.
• Investigating Helicobacter pylori interactions.

Main Results:

• Rebamipide reinforced epithelial barrier integrity under normal and inflammatory conditions.
• The drug normalized increased macromolecular transport caused by H. pylori infection.
• Rebamipide diminished allergic sensitization and counteracted H. pylori's inhibition of oral tolerance in mice.

Conclusions:

• Rebamipide enhances digestive epithelial barrier function.
• The compound exhibits anti-inflammatory effects on digestive mucosa.
• Rebamipide may protect against allergic sensitization and improve oral tolerance.
