Summary

This study aims to understand why some people who get a lung transplant develop rejection while others do not. Researchers will follow 100 adults aged 18 to 75 who have progressive lung disease or have had or may get a lung transplant. Participants will have regular check-ups, blood tests, lung function tests, and optional lung camera exams over up to 4 years. No new treatment is being tested; the goal is to collect data to improve future care.
