Spontaneous Inhibitory Synaptic Currents Mediated by a G Protein-Coupled Receptor
نویسندگان
چکیده
G protein-coupled receptors (GPCRs) affect many physiological processes by modulating both intrinsic membrane conductances and synaptic transmission. This study describes spontaneous miniature inhibitory postsynaptic currents mediated by vesicular dopamine release acting locally on metabotropic D2 receptors leading to the activation of a G protein-coupled inwardly rectifying potassium conductance. Thus, individual exocytotic events result in spontaneous GPCR-mediated transmission, similar to synaptic activation of classical ligand-gated ion channels.

Postnatal developmental alterations in the locus coeruleus neuronal fast excitatory postsynaptic currents mediated by ionotropic glutamate receptors of rat
Introduction: In the present work, spontaneous postsynaptic currents were assessed to investigate the postnatal development of excitatory postsynaptic currents in locus coeruleus neurons. Methods: In this study, AMPA and NMDA receptor-mediated spontaneous synaptic currents in the neurons of locus coeruleus were assessed using whole cell voltage-clamp recording during the first three weeks. ...
متن کاملNorepinephrine inhibits calcium currents and EPSPs via a G-protein-coupled mechanism in olfactory bulb neurons.
The most pronounced effect of norepinephrine (NE) in the olfactory bulb is disinhibition of mitral/tufted (M/T) cells. Although it has been previously proposed that the effects of NE are mediated by a direct inhibitory action on granule cells, we have demonstrated that NE could exert it effects through inhibition of excitatory synaptic transmission from M/T cells to granule cells (Trombley and ...
متن کاملA presynaptic action of the neurosteroid pregnenolone sulfate on GABAergic synaptic transmission.
The endogenous neurosteroid pregnenolone sulfate (PS) is known to enhance memory and cognitive function at nanomolar concentrations. However, the effect of these low concentrations on synaptic transmission has not been previously studied. The effects of PS on GABAA receptor-mediated inhibitory postsynaptic currents were studied in cultured hippocampal pyramidal neurons. Concentrations of PS sim...
متن کاملEffects of Ketamine on Neuronal Spontaneous Excitatory Postsynaptic Currents and Miniature Excitatory Postsynaptic Currents in the Somatosensory Cortex of Rats
Background: Ketamine is a commonly used intravenous anesthetic which produces dissociation anesthesia, analgesia, and amnesia. The mechanism of ketamine-induced synaptic inhibition in high-level cortical areas is still unknown. We aimed to elucidate the effects of different concentrations of ketamine on the glutamatergic synaptic transmission of the neurons in the primary somatosensory cortex b...
متن کاملSpontaneous synaptic activity is primarily GABAergic in vestibular nucleus neurons of the chick embryo.
The principal cells of the chick tangential nucleus are vestibular nucleus neurons participating in the vestibular reflexes. In 16-day embryos, the application of glutamate receptor antagonists abolished the postsynaptic responses generated on vestibular-nerve stimulation, but spontaneous synaptic activity was largely unaffected. Here, spontaneous synaptic activity was characterized in principa...
