What are the Histological Features of Autoimmune Diseases?
In autoimmune diseases, the body's immune system attacks its own tissues. Common histological features include:
- Inflammation: Accumulation of immune cells such as T cells, B cells, and macrophages in the affected tissues. - Tissue Damage: Destruction of normal tissue architecture, often seen in conditions like rheumatoid arthritis and lupus. - Fibrosis: Excessive deposition of connective tissue, which can be observed in organs like the kidneys in systemic lupus erythematosus.
