Serine racemase and alzheimer

Web1 Mar 2004 · The brain distribution of serine racemase closely resembles that of d-serine, and pharmacological inhibition of the enzyme diminishes d-serine levels in astrocytes, suggesting that serine racemase physiologically synthesizes d-serine, thereby playing a part in the regulation of the NMDA receptor Snyder and Ferris, 2000, Snyder and Kim, 2000, … WebThis strongly links D-serine to both Schizophrenia and Alzheimer’s Disease [99,100]. Free D-serine is primarily localized in the mammalian forebrain, along with the highest concentrations of NMDA receptor [104,105,106]. D-Serine is created by serine racemase by converting L-serine into D-serine, which it is metabolized by DAAO [42,43,83].

WebD-serine serves as a co-agonist of the N-methyl D-aspartate receptor in mammalian brains, and its behavior is probably related to neurological disorders such as schizophrenia, Alzheimer's disease and amyotrophic lateral sclerosis. D-Serine is synthesized by a pyridoxal 5'-phosphate (PLP)-dependent serine racemase.
