- Immunology
- Gastroenterology
Background
- Dysregulated intestinal barrier function is a key feature of inflammatory bowel disease.
- Current models for studying these conditions are limited.
- Understanding leukocyte migration is crucial for addressing gut inflammation.
- This model utilizes a well-vascularized, exteriorized bowel segment.
Purpose of Study
- To develop a physiological model for studying gut barrier function.
- To investigate the mechanisms of intestinal permeability.
- To explore immune cell recruitment in the context of intestinal inflammation.
Methods Used
- Mouse intestinal loop model employing exteriorized bowel segments.
- Assessment of mucosal permeability in vivo.
- Evaluation of leukocyte migration in the intestine.
- Surgical techniques to establish the model.
Main Results
