Role of nitric oxide during neurogenesis in the olfactory epithelium

ABSTRACT

In mammals, neurogenesis continues during adulthood in restricted places of the nervous system, namely the subventricular zone, the dentate gyms and the olfactory epithelium. A dual role of the second messenger nitric oxide has been reported in such places, either promoting or inhibiting proliferation of neuronal precursors depending on the cellular signal implicated. In this review the regulation of adult olfactory epithelium neurogenesis by nitric oxide is discussed.
