NK1 receptor stimulation causes contraction and inositol phosphate increase in medium-size human isolated bronchi.

abstract：:Inflammation is a critical component of asthma. Drugs that control asthma generally reduce the degree of airway inflammation. There is theoretical controversy surrounding the effects of beta(2)-agonists on airway inflammation, with some studies suggesting an anti-inflammatory effect, and others predicting a proinflamm...
