A Ca2+-based computational model for NDMA receptor-dependent synaptic plasticity at individual post-synaptic spines in the hippocampus

Frontiers in Synaptic Neuroscience, 2010
Associative synaptic plasticity is synapse specific and requires coincident activity in presynaptic and postsynaptic neurons to activate NMDA receptors (NMDARs). The resultant Ca2+ influx is the critical trigger for the induction of synaptic plasticity.

Pia Mater‐Penetrable Lipopolymer Nanoparticles for Gliocyte‐Targeted IL‐10 mRNA Therapy Alleviate Paclitaxel‐Induced Peripheral Neuropathy

Advanced Science, EarlyView.
The P6CIT lipopolymer demonstrates superior transfection efficacy in the spinal cord and DRG, as well as enhanced penetration of the pia mater compared to the MC3 ionizable lipid. Intrathecal delivery of P6CIT LPNPs enables effective transfection in the gliocytes in the spinal cord and DRG.

Neurexins play a crucial role in cerebellar granule cell survival by organizing autocrine machinery for neurotrophins

Cell Reports, 2022
Summary: Neurexins (NRXNs) are key presynaptic cell adhesion molecules that regulate synapse formation and function via trans-synaptic interaction with postsynaptic ligands.

Differential expression of an inwardly rectifying chloride conductance in rat brain neurons: a potential mechanism for cell-specific modulation of postsynaptic inhibition

Journal of Neuroscience, 1995
A voltage-sensitive inwardly rectifying chloride (Cl-) conductance (GCl(V) is present in hippocampal pyramidal but not dentate gyrus neurons and has a significant role in modulation of neuronal inhibition by GABA.

Effects of Ketamine on Neuronal Spontaneous Excitatory Postsynaptic Currents and Miniature Excitatory Postsynaptic Currents in the Somatosensory Cortex of Rats

Iranian Journal of Medical Sciences, 2016
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.

Postsynaptic activity of inhibitory neurons evokes hemodynamic fMRI responses

NeuroImage, 2021
Functional MRI responses are localized to the synaptic sites of evoked inhibitory neurons, but it is unknown whether, or by what mechanisms, these neurons initiate functional hyperemia.
