Involvement of enhanced neurokinin NK3 receptor expression in the severe asthma guinea pig model.
    European journal of pharmacology, 2004, Sep-13, Volume: 498, Issue:1-3

    In this study, we investigated the involvement of neurokinin NK3 receptors in a severe asthma model prepared by administering ovalbumin via inhalation three times to systemically sensitized guinea pigs. [3H]senktide, a neurokinin NK3 receptor ligand, showed significant specific binding to the lungs from the model animals, but not to those from negative control animals. The airway responsiveness to intravenous neurokinin B, a neurokinin NK3 receptor agonist, was increased in the model, indicating an increase in functional NK3 receptors. Furthermore, SB 223956 ((-)-3-methoxy-2-phenyl-N-[(1S)-phenylpropyl]quinoline-4-carboxamide), a selective neurokinin NK3 receptor antagonist, significantly inhibited the ovalbumin-induced airway hyperresponsiveness to inhaled methacholine, but it did not show significant effects on the ovalbumin-induced airway narrowing and eosinophil accumulation. These results suggest that the expressed neurokinin NK3 receptors in the severe asthma model are involved in the development of airway hyperresponsiveness.
