Collagen vascular disease

Definition

Collagen is a tough, glue-like protein that represents 30% of body protein and shapes the structure of tendons, bones, and connective tissues. Malfunctioning of the immune system can affect these structures. This is known as collagen vascular disease.

Collagen vascular diseases include:

• Rheumatoid arthritis
• Systemic lupus erythematosus
• Scleroderma
• Dermatomyositis
• Polyarteritis nodosa
