title: Distribution of D-amino acid oxidase (DAO) activity in the medulla and thoracic spinal cord of the rat: implications for a role for D-serine in autonomic function.
abstract: The activity and regional distribution of D-amino acid oxidase (DAO), an enzyme that inactivates D-serine, were examined in the medulla and spinal cord of the rat by biochemical and histochemical procedures. DAO activity was noticeably low or absent in the nucleus of the solitary tract, ventrolateral medulla and intramediolateral cell column of the spinal cord. This may be indicative of a neuromodulatory role for endogenous D-serine (at the NMDA-glycine site) in in the central control of blood pressure.
