Study Summary

This trial is testing how different environmental and genetic factors may affect lung function. It will screen participants over the course of one day, then have them come back for two days for more testing. This will include a blood draw and a breathing test before and after being exposed to either filtered air or ozone. Then, they will have a bronchoscopy to evaluate the lungs. They will repeat this process once more, 18-20 days later. There will be follow-up phone calls from the study team after each two-day test series. The whole study will last one to one-and-a-half months.

Mark “Yes” if the following statements are true for you:
is associated with increased response to CXCL10 The CXCR3 polymorphism rs2280964 is associated with a greater response to the chemokine CXCL10 in people with the wild-type gene expression, or in those who are homozygous for the CXCR3 variant (female) or hemizygous for the CXCR3 variant (male, since the gene is sex-linked).
of North Carolina People who live in the Raleigh-Durham area of North Carolina can enroll in a registry that tracks environmental polymorphisms.
