Munc13 controls the location and efficiency of dense-core vesicle release in neurons [PDF]

, 2012
Neuronal dense-core vesicles (DCVs) contain diverse cargo crucial for brain development and function, but the mechanisms that control their release are largely unknown. We quantified activity-dependent DCV release in hippocampal neurons at single vesicle

Neuronal Cholesterol Deficiency Mediated by Astrocytic SREBP2 Downregulation Leads to Postoperative Cognitive Dysfunction Through Impairment of Hippocampal Synaptic Plasticity and Excitatory Synaptic Transmission

Advanced Science, Volume 13, Issue 23, 23 April 2026.
The results showed that the reduction of plasma 24‐hydroxycholesterol (24‐OHC) was related to the cognitive decline in elderly surgical patients. Neuroinflammation induced by anesthesia and surgery significantly downregulated SREBP2 in hippocampal reactive astrocytes, resulting in reduced cholesterol synthesis.

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

The 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 ...

GABAA receptors and neuroligin 2 synergize to promote synaptic adhesion and inhibitory synaptogenesis

Frontiers in Cellular Neuroscience
GABAA receptors (γ-aminobutyric acid-gated receptors type A; GABAARs), the major structural and functional postsynaptic components of inhibitory synapses in the mammalian brain, belong to a family of GABA-gated Cl−/HCO3− ion channels.

Extrasynaptic NMDA receptor dependent long-term potentiation of hippocampal CA1 pyramidal neurons

Scientific Reports, 2017
In the adult mouse hippocampus, NMDA receptors (NMDARs) of CA1 neurons play an important role in the synaptic plasticity. The location of NMDARs can determine their roles in the induction of long-term potentiation (LTP). However, the extrasynaptic NMDARs

Defective GABAergic neurotransmission in the nucleus tractus solitarius in Mecp2-null mice, a model of Rett syndrome

Neurobiology of Disease, 2018
Rett syndrome (RTT) is a devastating neurodevelopmental disorder caused by loss-of-function mutations in the X-linked methyl-CpG binding protein 2 (Mecp2) gene.

Contribution of Cystine-Glutamate Antiporters to the Psychotomimetic Effects of Phencyclidine [PDF]

, 2008
Altered glutamate signaling contributes to a myriad of neural disorders, including schizophrenia. While synaptic levels are intensely studied, nonvesicular release mechanisms, including cystine–glutamate exchange, maintain high steady-state glutamate ...

Pathological Roles of Astrocytes in Traumatic Brain Injury

CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
TBI induces intrinsic astrocytic changes, including reactive astrogliosis, A1 and A2 polarization, ion channels activation, pathological edema, oxidative stress, and metabolic dysregulation. These injury‐responsive astrocytes regulate neuroinflammation and tissue remodeling through dynamic crosstalk with microglia, macrophages, vascular endothelial ...

Altered Regulation of Striatal Neuronal N-Methyl-D-Aspartate Receptor Trafficking by Palmitoylation in Huntington Disease Mouse Model

Frontiers in Synaptic Neuroscience, 2019
N-methyl-D-aspartate receptors (NMDARs) play a critical role in synaptic signaling, and alterations in the synaptic/extrasynaptic NMDAR balance affect neuronal survival.

In vivo evidence for NMDA receptor mediated excitotoxicity in a murine genetic model of Huntington Disease [PDF]

, 2008
N-methyl-D-aspartate receptor (NMDAR) mediated excitotoxicity is implicated as a proximate cause of neurodegeneration in Huntington Disease (HD). However, this hypothesis has not been tested rigorously in vivo. NMDAR NR2B-subunits are the predominant NR2
