Research is exploring the potential for rehabilitating damaged lungs as an alternative to transplants, particularly for patients with chronic conditions like sarcoidosis. Current lung transplants often face complications, with the disease frequently returning within two years, limiting their effectiveness. The discussion highlights the appeal of lung rehabilitation methods, especially given the challenges associated with gene and stem cell therapies. While these advancements are not imminent, they offer hope for patients who cannot undergo transplants. Overall, the conversation emphasizes the need for innovative treatments to improve lung health.
