Study Notes
Chronic Inflammation
- Chronic inflammation can be caused by prolonged exposure to irritants, infections, or autoimmune responses.
- Diseases like diabetes and atherosclerosis are often linked to visceral obesity due to its inflammatory effects on metabolic health.
Distinction from Acute Inflammation
- Chronic inflammation is characterized by prolonged persistence, immune cell infiltration, and tissue damage, contrasting with acute inflammation’s short-term and rapid response to injury.
Role of Macrophages
- Classically-activated (M1) macrophages increase inflammation and participate in immune response, while alternatively activated (M2) macrophages aid in tissue repair and resolution of inflammation.
- Pro-inflammatory macrophages secrete cytokines that amplify the inflammatory process, and they are critical for effective phagocytosis in chronic conditions.
Visceral Obesity and Chronic Inflammation
- Visceral obesity leads to excessive lipid accumulation in adipocytes, causing cellular stress and inflammation.
- Inflammation from excess adiposity contributes to the activation of lymphocytes, cell division, connective tissue deposition, and angiogenesis.
Immune Response and Diseases
- Chronic inflammation is linked with various autoimmune diseases, often mediated by different immune responses (Th2 for allergies and Th17 for inflammatory diseases).
- Autoimmune diseases are primarily mediated by a mix of inflammatory and adaptive immune responses.
Healing Process
- The healing process begins with inflammation, followed by angiogenesis and tissue repair.
- Type 3 collagen is laid down during early healing phases, transforming to the stronger Type 1 collagen in later stages.
Granulomas
- Granulomas consist of aggregated macrophages that have transformed into epithelium-like cells, a hallmark of diseases such as tuberculosis, which features caseating necrosis.
Miscellaneous
- Prolonged toxin exposure can lead to chronic inflammation and tissue damage.
- Tertiary lymphoid organs are significant in the inflammation process of autoimmune diseases like Rheumatoid Arthritis.
