MRI-Bronch, PET-WLAC (Stress vs Control)
Subjects will have a functional MRI scan 24 hours before a bronchoscopy with segmental allergen challenge. 48 hours post segmental allergen challenge, the subject will have another MRI and bronchoscopy. 4-6 weeks later, subjects will have a PET scan and whole lung antigen challenge under a stress condition or control condition. 4-6 weeks later, subject will have another PET scan and whole lung antigen challenge under a stress condition or control condition (whatever they did not have the first time).
Biological: Whole lung antigen challenge, segmental allergen challenge
Whole lung antigen challenge with housedust mite, short ragweed or cat hair allergen extracts. Segmental allergen challenge with housedust mite, short ragweed or cat hair allergen extracts.
Other Name: House dust mite, short ragweed, cat hair allergen extracts
- Bronchoalveolar Eosinophils pre vs post antigen challenge [ Time Frame: 48 hours ]The percent of eosinophils will be measured from the Bronchoalveolar lavage fluid pre segmental allergen challenge and will be measured 48 hours post segmental allergen challenge.
- Sputum Eosinophils pre stress condition vs post stress condition [ Time Frame: 72 hours ]The percent of eosinophils will be measured from the sputum fluid pre stress condition and will be measured up to 72 hours later (post stress condition).
- Sputum Eosinophils pre control condition vs post control condition [ Time Frame: 72 hours ]The percent of eosinophils will be measured from the sputum fluid pre control condition and will be measured up to 72 hours later (post control condition).
