Synergistic mechanisms in the adenosine- and neuropeptide-induced bronchoconstriction.
Neuropeptides and purines are possible neurotransmitters of the nonadrenergic noncholinergic nervous system of the airways. We investigated possible synergistic mechanisms between these two bronchoconstricting agents in a rat model. We observed that both adenosine and tachykinins enhance histamine release in the airways and that adenosine and neurokinin A act synergistically both on airway narrowing and histamine release.
