Here's why:
* Autoimmunity: This refers to the immune system's failure to distinguish between self and non-self.
* Antibodies: These are proteins produced by the immune system to fight off infections. In autoimmune diseases, antibodies mistakenly target and attack the body's own cells and tissues.
Examples of autoimmune diseases include:
* Rheumatoid arthritis: Antibodies attack the lining of joints.
* Systemic lupus erythematosus (lupus): Antibodies attack various tissues, including joints, skin, and kidneys.
* Multiple sclerosis: Antibodies attack the myelin sheath, which protects nerve fibers.
* Type 1 diabetes: Antibodies attack insulin-producing cells in the pancreas.
* Crohn's disease and ulcerative colitis: Antibodies attack the lining of the digestive tract.
* Myasthenia gravis: Antibodies attack receptors in the muscles, leading to weakness.
Autoimmune diseases are complex and often difficult to diagnose and treat.
