简介：
Overview
This protocol describes a mouse model of Salmonella driven intestinal fibrosis that closely resembles key pathological features of Crohn��s disease, including transmural inflammation and fibrosis. This model can be utilized to assess host factors that influence fibrotic outcomes using mutant mice on a C57Bl/6 genetic background.
Key Study Components
Area of Science
- Neuroscience
- Biology
- Pathology
Background
- Tissue fibrosis is a major cause of organ failure due to chronic inflammation or aging.
- Current mouse models for human tissue fibrosis are limited.
- Crohn's disease is a human condition that leads to gut fibrosis and is difficult to treat.
- Surgical removal of fibrotic tissue is often the only treatment option.
Purpose of Study
- To develop a robust mouse model that mimics human Crohn's disease.
- To evaluate the fibrotic response in a controlled environment.
- To explore host factors affecting fibrosis outcomes.
Methods Used
- Utilization of a mouse model infected with Salmonella.
- Assessment of fibrotic changes over time.
- Comparison of mutant mice on a C57Bl/6 background.
- Evaluation of transmural inflammation and fibrosis.
Main Results
- The model demonstrates persistent fibrosis for over a month.
- It closely mimics the pathology of human Crohn's disease.
- All mouse strains show full penetrance of the model.
- Host factors can be evaluated for their impact on fibrosis.
Conclusions
- This model provides a valuable tool for studying intestinal fibrosis.
- It may lead to better understanding and treatment options for Crohn's disease.
- Further research can explore genetic and environmental influences on fibrosis.
