This study collects samples from your lungs and airways to help researchers better understand lung diseases. It is not a treatment study, but your participation could help improve future care for people with lung conditions.

This study collects sent-in samples to better understand how your immune system responds during a COVID-19–like illness and after you recover. It may help researchers learn why some people get sick and others stay uninfected, and how immune protection works over time.

This study looks at how the body’s “innate” (first-line) immune system works in people with COPD compared with healthy volunteers. It may help researchers understand COPD inflammation and how immune responses could be targeted in the future.

This study looks at air in inner-city schools and how it may affect children’s health. You may be asked to collect nasal swab samples at home and answer questions, especially if your child’s classroom is part of the study.
