Study of Inflammatory and Physiological Profiles of Healthy and Diseased Lung
There are over 700,000 UK hospital admissions every year with lung disease symptoms. Two of the most common lung diseases contributing to these numbers are asthma and chronic obstructive pulmonary disease (COPD). The immunopathology of these diseases is not fully understood. Matched samples from the respiratory tract and circulation will be used to identify immune patterns throughout the respiratory system to elucidate the immunopathology of airway disease.

About this study
There are over 700,000 UK hospital admissions every year with lung disease symptoms. Two of the most common lung diseases contributing to these numbers are asthma and chronic obstructive pulmonary disease (COPD). The immunopathology of these diseases is not fully understood. Matched samples from the respiratory tract and circulation will be used to identify immune patterns throughout the respiratory system to elucidate the immunopathology of airway disease.
Primary outcomes
- Blood samples for presence of airway disease immune endotypes (6 years)
