Study Notes
Chronic Inflammation
- Damaged tissue and exposure to toxic substances or pathogens initiate the process of tissue repair in chronic inflammation.
Cells Involved in Chronic Inflammation
- Macrophages, lymphocytes, and plasma cells are key cells involved in chronic inflammation.
Causes of Chronic Inflammation
- Prolonged exposure to pollutants, irritants, or allergens, such as silica or asbestos, can lead to chronic inflammation of the lung.
Role of Macrophages
- Macrophages play a crucial role in chronic inflammation by engulfing foreign substances and producing chemical signals that attract other immune cells to the site of inflammation.
Progression from Acute to Chronic Inflammation
- Inadequate resolution of acute inflammation, persistent infection, or autoimmune disorders may cause chronic inflammation following acute inflammation.
