About This Trial
The goal of this study is to learn how the body's immune system affects disease control in people with different airway inflammatory diseases.We want to understand:
1.Whether specific immune cell patterns in the blood are linked to how severe the disease is or how well it is controlled.
Participants will:
1. Answer questions about their health and symptoms.
2. Give blood samples
3. Have lung fu…
