Overview
This protocol describes a method for establishing a mouse model of silicosis through repeated exposure to silica suspensions via a nasal drip. This model can efficiently mimic the pathological process of human silicosis with high repeatability and economy.
Key Study Components
Area of Science
- Neuroscience
- Pathology
- Respiratory Diseases
Background
- Silicosis is a lung disease caused by inhaling silica dust.
- Existing models may not accurately replicate human disease.
- There is a need for a practical and effective model for research.
