Extrasynaptic Neurotransmission as a Way of Modulating Neuronal Functions [PDF]

open access: yesFrontiers in Physiology, 2012
Extrasynaptic neurotransmission allows neuronal communication at variable distances, based on the release and diffusion of chemical substances from the soma, axon, or dendrites of neurons, or after transmitter leak-out from the synaptic cleft (De-Miguel and Trueta, 2005; Fuxe et al., 2007).

Tonic neuromodulation of the inspiratory rhythm generator

open access: yesFrontiers in Physiology, 2012
The generation of neural network dynamics relies on the interactions between the intrinsic and synaptic properties of their neural components. Moreover, neuromodulators allow networks to change these properties and adjust their activity to specific ...

A Jacob/nsmf gene knockout does not protect against acute hypoxia- and NMDA-induced excitotoxic cell death

open access: yesMolecular Brain, 2023
Jacob is a synapto-nuclear messenger protein that encodes and transduces the origin of synaptic and extrasynaptic NMDA receptor signals to the nucleus. The protein assembles a signalosome that differs in case of synaptic or extrasynaptic NMDAR activation.

Exocytosis of serotonin from the neuronal soma is sustained by a serotonin and calcium-dependent feedback loop

open access: yesFrontiers in Cellular Neuroscience, 2014
The soma of many neurons releases large amounts of transmitter molecules through an exocytosis process that continues for hundreds of seconds after the end of the triggering stimulus.

Extrasynaptic NMDA Receptor in Excitotoxicity [PDF]

open access: yesThe Neuroscientist, 2014
It is generally accepted that proper activation of N-methyl-d-aspartate receptors (NMDARs) promotes neuronal survival and supports neuroplasticity, and excessive NMDAR activation leads to pathological outcomes and neurodegeneration. As NMDARs are found at both synaptic and extrasynaptic sites, there is significant interest in determining how NMDARs at

Extrasynaptic neurotransmission in the modulation of brain function. Focus on the striatal neuronal-glial networks

open access: yesFrontiers in Physiology, 2012
Extrasynaptic neurotransmission is an important short distance form of volume transmission (VT) and describes the extracellular diffusion of transmitters and modulators after synaptic spillover or extrasynaptic release in the local circuit regions ...

Functional characterization of dopamine transporter in vivo using Drosophila melanogaster behavioral analysis.

open access: yesFrontiers in Behavioral Neuroscience, 2014
Dopamine mediates diverse functions such as motivation, reward, attention, learning/memory and sleep/arousal. Recent studies using model organisms including the fruit fly, have elucidated various physiological functions of dopamine, and identified ...

Extrasynaptic GABAAReceptors: Form, Pharmacology, and Function [PDF]

open access: yesThe Journal of Neuroscience, 2009
GABA is the principal inhibitory neurotransmitter in the CNS and acts via GABAAand GABABreceptors. Recently, a novel form of GABAAreceptor-mediated inhibition, termed “tonic” inhibition, has been described. Whereas synaptic GABAAreceptors underlie classical “phasic” GABAAreceptor-mediated inhibition (inhibitory postsynaptic currents), tonic ...

The Disruption of NMDAR/TRPM4 Death Signaling with TwinF Interface Inhibitors: A New Pharmacological Principle for Neuroprotection

open access: yesPharmaceuticals, 2023
With the discovery that the acquisition of toxic features by extrasynaptic NMDA receptors (NMDARs) involves their physical interaction with the non-selective cation channel, TRPM4, it has become possible to develop a new pharmacological principle for ...

Thermodynamic Efficiency of Somatic Exocytosis of Serotonin

open access: yesFrontiers in Physiology, 2019
Through somatic exocytosis neurons liberate immense amounts of transmitter molecules that modulate the functioning of the nervous system. A stream of action potentials triggers an ATP-dependent transport of transmitter-containing vesicles to the plasma ...
