45th Annual Thomas L. Petty Aspen Lung Conference was held June 5 to 8, 2002. The title the conference was “Asthma in the New Millennium.” In planning this meeting, the organizers realized that the “explosion” of new information in regard to the pathophysiology and therapy for asthma would bring cutting edge scientific exchange throughout the sessions. This Aspen Lung Conference was planned with an emphasis on the basic and translational sciences, but also included new and novel therapies for asthma. The conference attendance reached another all-time high, which included scientists from 13 different countries. This, indeed, led to the excellent exchange of ideas and new information at an exceptionally high level.
