Frontiers in synaptic neuroscience

Sasabe J, Suzuki M, Imanishi N, Aiso S.
PMID: 24959138
Front Synaptic Neurosci. 2014 Jun 10;6:14. doi: 10.3389/fnsyn.2014.00014. eCollection 2014.

It has been proposed that D-amino acid oxidase (DAO) plays an essential role in degrading D-serine, an endogenous coagonist of N-methyl-D-aspartate (NMDA) glutamate receptors. DAO shows genetic association with amyotrophic lateral sclerosis (ALS) and schizophrenia, in whose pathophysiology aberrant...

Potential therapeutic role of glutamate transporter 1 for the treatment of alcohol dependence.

OA Alcohol. 2013;1(1):6. doi: 10.13172/2053-0285-1-1-574.

INTRODUCTION: Evidence has demonstrated that deficits in glutamate transmission impair neurocircuits involved in drug abuse or drug-seeking behaviour and affect many aspects of neuroplasticity associated with alcohol and drug addiction. Alcohol-seeking behaviour is promoted by increased glutamate transmission in...

Chronic exposure to high levels of manganese (Mn) leads to manganism, a neurological disorder with similar symptoms to those inherent to Parkinson's disease. However, the underlying mechanisms of this pathological condition have yet to be established. Since the human...

Methamphetamine Activates Trace Amine Associated Receptor 1 to Regulate Astrocyte Excitatory Amino Acid Transporter-2 via Differential CREB Phosphorylation During HIV-Associated Neurocognitive Disorders.

Frontiers in neurology

Front Neurol. 2020 Nov 25;11:593146. doi: 10.3389/fneur.2020.593146. eCollection 2020.

Methamphetamine (METH) use, referred to as methamphetamine use disorder (MUD), results in neurocognitive decline, a characteristic shared with HIV-associated neurocognitive disorders (HAND). MUD exacerbates HAND partly through glutamate dysregulation. Astrocyte excitatory amino acid transporter (EAAT)-2 is responsible for >90%...
