** Prof. Richard F. Lockey, MD, World Allergy Organisation (WAO) Web Editor-in-Chief, reviewed premier medical journal articles for practicing allergists in 2007 and this work was selected as one of his top four picks to read (ref: WAO News & Notes - July 2007 Volume 4, Issue 7). This is an important study as it is the first human model of airway fibrosis and is the first study to show that airway hyper-responsiveness can be dissociated from inflammation but not tissue fibrosis.
