G protein-coupled receptors mediate a fast excitatory postsynaptic current in CA3 pyramidal neurons in hippocampal slices

open access: yesJournal of Neuroscience, 1995
Synaptic activation in the presence of competitive (D,L-APV,CNQX) and noncompetitive (MK-801,GYKI-52466) ionotropic glutamate receptor antagonists induced fast (10–90% rise time of 15–30 msec) postsynaptic responses in CA3 pyramidal neurons from acute ...

Igfbp2 Downregulation in PVT‐CeA Glutamatergic Circuits Drives Neonatal Anesthesia‐Induced Fear Memory Deficits

open access: yesAdvanced Science, EarlyView.
Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

Intrinsic Conductances Actively Shape Excitatory and Inhibitory Postsynaptic Responses in Olfactory Bulb External Tufted Cells

open access: yesJournal of Neuroscience, 2008
The initial synapse in the olfactory system is from olfactory nerve (ON) terminals to postsynaptic targets in olfactory bulb glomeruli. Recent studies have disclosed multiple presynaptic factors that regulate this important linkage, but less is known ...

Elevated Apolipoprotein E Expression in Hippocampal Microglia Drives Temporal Lobe Epilepsy Progression

open access: yesAdvanced Science, EarlyView.
In temporal lobe epilepsy, hippocampal APOE is markedly upregulated predominantly in microglia. APOE overexpression in microglia drives TLR4 and cGAS/STING‐dependent neuroinflammation, engages bidirectional crosstalk with neurons and astrocytes, increases neuronal excitability, and perturbs hippocampal lipid metabolism. These findings suggest that APOE‐

A Van Der Waals Broadband Infrared Optical Synapse Enabling Orientation Detection

open access: yesAdvanced Science, EarlyView.
An infrared optoelectronic synapse based on a graphene/CrOCl/graphene van der Waals heterostructure is reported to possess a broadband synaptic response range from the visible to the infrared (520–2000 nm), which can be used to achieve orientation and motion detections of a target mimicing the pit organ of a pit vapor.

Targeting ROCK2 to Restore Epileptic Synaptic Networks via Mitophagy Activation: Insights from Translational Imaging of SV2A In Vivo

open access: yesAdvanced Science, EarlyView.
By integrating synaptic vesicle glycoprotein 2A PET imaging and transcriptomics, this study identifies Rho‐associated protein kinase 2 (ROCK2) as a critical regulator of synaptic network dysfunction in temporal lobe epilepsy. Pharmacological ROCK2 inhibition restores synaptic density and enhances mitophagy, thereby reducing seizures and neuronal damage.

Spike-timing dependent plasticity in inhibitory circuits

open access: yesFrontiers in Synaptic Neuroscience, 2010
Inhibitory circuits in the brain rely on GABA-releasing interneurons. For long, inhibitory circuits were considered weakly plastic in the face of patterns of neuronal activity that trigger long-term changes in the synapses between excitatory principal ...

Targeting Histamine H4 Receptor in the Rostral Ventromedial Medulla to Relieve Hypertension

open access: yesAdvanced Science, EarlyView.
H4R and its downstream TRPV1 channel mediate the excitatory effect of TMN histaminergic afferent inputs on GABAergic sympathoinhibitory neurons in RVMM. Intranasal delivery of selective H4R agonist VUF 8430 suppresses renal sympathetic outflow and elicits sustained depressor and bradycardia responses in SHRs and CUMS‐induced hypertensive rats ...

Allele‐Specific Regulation of PAXIP1‐AS1 by SMC3/CEBPB at rs112651172 in Psychiatric Disorders Drives Synaptic and Behavioral Dysfunctions in Mice

open access: yesAdvanced Science, EarlyView.
This study identifies a functional noncoding variant, rs112651172 (C/G), that drives allele‐specific expression of PAXIP1‐AS1 in monozygotic twin pairs discordant for schizophrenia and bipolar disorder. The risk G allele enhances CEBPB binding, leading to lncRNA upregulation, CNTNAP3 derepression, and synaptic and behavioral deficits in mice.
