Parasubthalamic Glutamatergic Neurons Coordinate Cardiovascular Homeostasis and Locomotion in Mice

Advanced Science, EarlyView.
PSTNVglut2 neurons function as a new central baroreflex hub via projections to the NTS, modulating parasympathetic cardiac output to maintain cardiovascular homeostasis while synchronously regulating locomotion. Blood pressure fluctuations negatively correlate with locomotor performance.

Role of Connexin 36 in Autoregulation of Oxytocin Neuronal Activity in Rat Supraoptic Nucleus

ASN Neuro, 2019
In the supraoptic nucleus (SON), the incidence of dye coupling among oxytocin (OT) neurons increases significantly in nursing mothers. However, the type(s) of connexin (Cx) involved is(are) unknown.

Human iPSC‐Derived Mononuclear Phagocytes Improve Cognition and Neural Health across Multiple Mouse Models of Aging and Alzheimer's Disease

Advanced Science, EarlyView.
Short‐term intravenous treatments with iPSC‐derived mononuclear phagocytes (iMPs) improve cognitive decline and neural health in two mouse models of aging and in the 5xFAD mouse model of Alzheimer's disease. iMPs reduce levels of serum amyloid proteins that increase in aging and improve the health of hippocampal microglia and mossy cells.

Associative memory model with long-tail-distributed Hebbian synaptic connections

Frontiers in Computational Neuroscience, 2013
The postsynaptic potentials of pyramidal neurons have a non-Gaussian amplitude distribution with a heavy tail in both hippocampus and neocortex. Such distributions of synaptic weights were recently shown to generate spontaneous internal noise optimal ...

Pigment Epithelium‐Derived Factor Deficiency Impairs Hippocampal Glutamate Homeostasis and Cognitive Function by Downregulating Astrocytic GLT‐1

Advanced Science, EarlyView.
The chronic glutamate‐induced excitotoxicity hypothesis has profoundly informed the therapeutic strategies employed in Alzheimer’s disease (AD). This study shows pigment epithelium‐derived factor (PEDF) regulates astrocytic glutamate transporter‐1 (GLT‐1)‐mediated glutamate homeostasis and cognition. Reduced PEDF correlates with lower Mini‐Mental State

Persistent sodium current blockers can suppress seizures caused by loss of low‐threshold D‐type potassium currents: Predictions from an in silico study of Kv1 channel disorders

Epilepsia Open, 2020
Objective Ion channels belonging to subfamily A of voltage‐gated potassium channels (Kv1) are highly expressed on axons, where they play a key role in determining resting membrane potential, in shaping action potentials, and in modulating action ...

A Peripheral Mechanism of Depression: Disturbed Intestinal Epithelial Per2 Gene Expression Causes Depressive Behaviors in Mice with Circadian Rhythm Disruption via Gut Barrier Damage and Microbiota Dysbiosis

Advanced Science, EarlyView.
Circardian rhythm disorder (CRD) causes abnormal expression of intestinal Period 2 (Per2) gene, which compromising intestinal barrier integrity and altering the gut microenvironment. Microbiota dysbiosis and aberrant metabolites production drive central inflammation, impair neurogenesis, and promote functional deficits, ultimately facilitating the ...

High- and low-conductance NMDA receptors are present in layer 4 spiny stellate and layer 2/3 pyramidal neurons of mouse barrel cortex

, 2016
NMDA receptors are ion channels activated by the neurotransmitter glutamate in the mammalian brain and are important in synaptic function and plasticity, but are also found in extrasynaptic locations and influence neuronal excitability.

Corticosterone Contributes to Context‐Triggered Retrieval of Morphine Withdrawal Memories by Acting on Basolateral Amygdala Neurons Projecting to Nucleus Accumbens Core

Advanced Science, EarlyView.
Context associated with morphine withdrawal elicits an increase in serum corticosterone levels. Corticosterone participates in CTR‐MWM by acting on MR, but not GR, in the BLA. MR in BLA→NAcC neurons mediates CTR‐MWM. MR increases presynaptic glutamate release and meanwhile participates in D1 receptor‐induced increases in presynaptic glutamate release ...
