The purpose of this study is to assess the loss of S-nitrosothiols, natural occurring airway dilators in the lung in asthma.

By evaluating the function of these proteins in airway fluid and lung cells, we will gain further understanding of asthma and hopefully be able to find new treatments for asthma.
