Extrasynaptic CaMKIIα is involved in the antidepressant effects of ketamine by downregulating GluN2B receptors in an LPS-induced depression model

Journal of Neuroinflammation, 2020
Background A subanesthetic dose of ketamine provides rapid and effective antidepressant effects, but the molecular mechanism remains elusive. It has been reported that overactivation of extrasynaptic GluN2B receptors is associated with the antidepressant

Molecular Tools to Study and Control Dopaminergic Neurotransmission With Light

Medicinal Research Reviews, EarlyView.
ABSTRACT Dopaminergic neurotransmission is involved in several important brain functions, such as motor control, learning, reward‐motivated behavior, and emotions. Dysfunctions of dopaminergic system may lead to the development of various neurological and psychiatric disorders, like Parkinson's disease, schizophrenia, depression, and addictions ...

Extrasynaptic site of action for γ-hydroxybutyrate [PDF]

Proceedings of the National Academy of Sciences, 2012
Advances in pharmacology often result from identifying the mechanism of action of drugs found empirically to be biologically active (1). γ-Hydroxybutyric acid (GHB), also known as Fantasy, is a centrally active agent that has been used clinically and recreationally for nearly half a century.

Rapid homeostatic downregulation of LTP by extrasynaptic GluN2B receptors [PDF]

Journal of Neurophysiology, 2018
Although the activation of extrasynaptic GluN2B-containing N-methyl-d-aspartate (NMDA) receptors has been implicated in neurodegenerative diseases, such as Alzheimer’s and Huntington’s disease, their physiological function remains unknown. In this study, we found that extrasynaptic GluN2B receptors play a homeostatic role by antagonizing long-term ...

GABA potency at GABAA receptors found in synaptic and extrasynaptic zones

Frontiers in Cellular Neuroscience, 2012
The potency of GABA is vitally important for its primary role in activating GABAA receptors and acting as an inhibitory neurotransmitter. Although numerous laboratories have presented information, directly or indirectly, on GABA potency, it is often ...

Craving self‐reports as outcome measures in drug addiction trials: A systematic review of ClinicalTrials.gov

Addiction, EarlyView.
Abstract Background and Aims The subjective experience of drug craving is characterized by an overwhelming urge to consume substances. Due to strong validity and ease of use, self‐report measures are widely employed to assess substance‐related motivational dynamics.

Natural aminosterols inhibit NMDA receptors with low nanomolar potency

The FEBS Journal, EarlyView.
Misfunction of N‐methyl‐D‐aspartate (NMDA) receptors is associated with many brain disorders, making them primary targets for drug discovery. Trodusquemine and other natural aminosterols inhibit NMDA receptors with low nanomolar potency through binding to the cell membranes followed by interaction with the channels.

Anorectic and anxiogenic actions of cocaine‐ and amphetamine‐regulated transcript in the lateral septum

Journal of Neuroendocrinology, EarlyView.
Abstract Cocaine‐ and amphetamine‐regulated transcript (CART) is produced in several brain regions including the hypothalamus where it is made in cells that also produce melanin‐concentrating hormone (MCH). CART‐expressing MCH cells densely innervate the lateral septum (LS), which integrates food‐ and mood‐related behaviours.

Pathophysiological power of improper tonic GABAA conductances in mature and immature models

Frontiers in Neural Circuits, 2013
High-affinity extrasynaptic gamma-aminobutyric acid A (GABAA) receptors are tonically activated by low and consistent levels of ambient GABA, mediating chronic inhibition against neuronal excitability (tonic inhibition) and the modulation of neural ...

Changes in the cortical GABAergic inhibitory system with ageing and ageing‐related neurodegenerative diseases

The Journal of Physiology, EarlyView.
Abstract figure legend With ageing and age‐related neurodegenerative diseases, the amount of GABA and GABAergic inhibition as well as the modulation (indicated by sine wave) of GABAergic inhibition is reduced, whereas excitation is increased. In many parts of the brain, this leads to a mismatch of facilitatory (green neurons) and inhibitory (red ...
