Sarcoidosis is a complex inflammatory disease that primarily affects the lungs and lymph nodes, but can also involve other organs such as the skin, eyes, and heart. The exact cause of sarcoidosis is unknown, but it is believed to be an autoimmune condition where the immune system attacks healthy tissues in the body. Research in sarcoidosis focuses on understanding the underlying mechanisms of the disease, identifying genetic and environmental risk factors, improving diagnostic tools, developing new treatments, and improving the quality of life for patients. Current treatments for sarcoidosis include corticosteroids, immunosuppressive drugs, and biologic therapies. Overall, research in sarcoidosis aims to improve our understanding of the disease and develop more effective and personalized treatment options for patients.
