Monoamine modulation of tonic GABAA inhibition [PDF]

open access: yesReviews in the Neurosciences, 2014
In recent years, it has become evident that many neurotransmitters and endogenous ligands differentially modulate synaptic γ-aminobutyric acid type A receptors (sGABAARs) and extrasynaptic GABAAR (eGABAARs). In this mini-review, we will summarize the available evidence on the ability of the monoamines serotonin (5-HT), noradrenaline (NA), and, in ...

Tonic inhibition of chemotaxis in human plasma [PDF]

open access: yesProceedings of the National Academy of Sciences, 2008
We found exaggerated chemotaxis in plasma treated with EDTA and thought that the EDTA might itself be inhibiting a tonic inhibitor(s) of chemotaxis. Our plasma fractionations suggested that evidence should be sought for a lipid moiety carrying this activity, and on spectrometry (LC-MS-MS together with GC-MS analyses), the biologically active but not ...

Activity-Dependent Modulation of Tonic GABA Currents by Endocannabinoids in Hirudo verbana

open access: yesFrontiers in Synaptic Neuroscience, 2022
Endocannabinoids are lipid neuromodulators that are synthesized on demand and primarily signal in a retrograde manner to elicit depression of excitatory and inhibitory synapses.

Tonic inhibition of chronic pain by neuropeptide Y [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
Dramatically up-regulated in the dorsal horn of the mammalian spinal cord following inflammation or nerve injury, neuropeptide Y (NPY) is poised to regulate the transmission of sensory signals. We found that doxycycline-induced conditional in vivo ( Npy tet/tet ) knockdown

A new meaning for “Gin & Tonic”: tonic inhibition as the target for ethanol action in the brain [PDF]

open access: yesAlcohol, 2007
Gamma-aminobutyric acid (GABA) is the main chemical inhibitory neurotransmitter in the brain. In the central nervous system, it acts on two distinct types of receptor: an ion channel, that is, an "ionotropic" receptor permeable to Cl- and HCO3- (GABAA receptors [GABAARs]) and a G-protein coupled "metabotropic" receptor that is linked to various ...

Enhanced tonic GABAA inhibition in typical absence epilepsy [PDF]

open access: yesNature Medicine, 2009
The cellular mechanisms underlying typical absence seizures, which characterize various idiopathic generalized epilepsies, are not fully understood, but impaired gamma-aminobutyric acid (GABA)-ergic inhibition remains an attractive hypothesis. In contrast, we show here that extrasynaptic GABA(A) receptor-dependent 'tonic' inhibition is increased in ...

Metabotropic Regulation of Extrasynaptic GABAA Receptors

open access: yesFrontiers in Neural Circuits, 2013
A large body of work now shows the importance of GABAA receptor-mediated tonic inhibition in regulating CNS function. However, outside of pathological conditions, there is relatively little evidence that the magnitude of tonic inhibition is itself under ...

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

open access: yesFrontiers 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 ...

Tonic Inhibition of TRPV3 by Mg2+ in Mouse Epidermal Keratinocytes [PDF]

open access: yesJournal of Investigative Dermatology, 2012
The transient receptor potential vanilloid 3 channel (TRPV3) is abundantly expressed in epidermal keratinocytes and has important roles in sensory biology and skin health. Mg(2+) deficiency causes skin disorders under certain pathological conditions such as type 2 diabetes mellitus.

The amount of astrocytic GABA positively correlates with the degree of tonic inhibition in hippocampal CA1 and cerebellum

open access: yesMolecular Brain, 2011
A tonic form of synaptic inhibition occurs in discrete regions of the central nervous system and has an important role in controlling neuronal excitability.
