FGF-2 Induces Neuronal Death through Upregulation of System xc- [PDF]

, 2014
The cystine/glutamate antiporter (system xc-) transports cystine into cell in exchange for glutamate. Fibroblast growth factor-2 (FGF-2) upregulates system xc- selectively on astrocytes, which leads to increased cystine uptake, the substrate for ...

Genetically altered AMPA-type glutamate receptor kinetics in interneurons disrupt long-range synchrony of gamma oscillation [PDF]

, 2001
Gamma oscillations synchronized between distant neuronal populations may be critical for binding together brain regions devoted to common processing tasks.

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.

Acid-Sensing Ion Channels Activated by Evoked Released Protons Modulate Synaptic Transmission at the Mouse Calyx of Held Synapse [PDF]

, 2017
Acid-sensing ion channels (ASICs) regulate synaptic activities and play important roles in neurodegenerative diseases. We found that these channels can be activated in neurons of the medial nucleus of the trapezoid body (MNTB) of the auditory system in ...

Development of AMPA Receptor Aptamers [PDF]

Biophysical Journal, 2010
The α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) subtype of glutamate ion channel receptors plays an essential role in the mammalian brain activities such as memory and learning, whereas the excessive receptor activation has been implicated in neurological diseases such as stroke, epilepsy, and amyotrophic lateral sclerosis.

Epigenetic Regulation of DAPK1 and Netrin‐1 Drives Diabetic Encephalopathy

Advanced Science, EarlyView.
This study identifies a microRNA (miR)‐216a‐5p/death‐associated protein kinase 1 (DAPK1)/hepatocyte nuclear factor 1 homeobox A (HNF1A)/Netrin‐1 signaling axis in diabetic encephalopathy (DE). In leptin receptor‐deficient (db/db) and streptozotocin (STZ)‐induced diabetic mice, reduced miR‐216a‐5p increases DAPK1 expression, disrupting HNF1A binding to ...

Food-induced behavioral sensitization, its cross-sensitization to cocaine and morphine, pharmacological blockade, and effect on food intake [PDF]

, 2006
Repeated administration of abused drugs sensitizes their stimulant effects and results in a drug-paired environment eliciting conditioned activity. We tested whether food induces similar effects.

Impaired AMPA signaling and cytoskeletal alterations induce early synaptic dysfunction in a mouse model of Alzheimer's disease

Aging Cell, 2018
Alzheimer's disease (AD) is a devastating neurodegenerative disorder that impairs memory and causes cognitive and psychiatric deficits. New evidences indicate that AD is conceptualized as a disease of synaptic failure, although the molecular and cellular

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 ...

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

Advanced 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 ...
