| pubmed-article:10457518 | pubmed:abstractText | Human nasal mucosa is a highly regulated tissue that performs a wide range of physiological functions. In addition to the classic and peptidergic neurotransmitters, the endogenously produced free radical gas nitric oxide (NO) has been found to be increasingly important for the vascular regulation of this tissue. NO-dependent control of vascular tone works in two ways, consisting of neurally produced NO acting as a neurotransmitter on the one hand and endothelially produced NO on the other hand. Neurons and endothelial cells contain various isoforms of the enzyme nitric oxide synthase, which forms NO out of L-arginine. The aim of this study was to examine the distribution of endothelial constitutive NO-synthase (ecNOS) in the human nasal mucosa of inferior turbinates. | lld:pubmed |
