Introduction to Immunopathology
1. Definition of Immunopathology:
Immunopathology refers to the study of diseases caused by the immune system's response to the body’s own tissues, leading to inflammation and tissue damage. These diseases occur when the immune system mistakenly attacks healthy cells and tissues instead of protecting the body from pathogens or foreign substances.
2. Types of Immunopathological Diseases :
- Autoimmune Diseases: Diseases where the immune system attacks the body’s own tissues.
- Immune Complex Diseases: These occur when immune complexes (antigen-antibody complexes) form and deposit in tissues, causing inflammation.
- Hypersensitivity Reactions: Exaggerated immune responses to harmless substances, such as allergens, which result in tissue damage.
