Relationship between airway responsiveness to neurokinin A and methacholine in asthma.


Non-adrenergic non-cholinergic (NANC) nerves release bronchoactive tachykinins such as substance P (SP) and neurokinin A (NKA) that can induce features of asthma. The airway response to NKA in humans closely resembles that of methacholine (M). Hence, we investigated the relationship between airway responsiveness to NKA and M in subjects with asthma. To this… (More)
