Application

CNQX has been used:
  • as an α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)/kainate blocker to study its effects on cytoneme formation in pluripotent embryonic stem cells (pESCs)
  • glutamate blocker to reduce the synaptic input during current-clamp recordings in central antennal lobe neurons
  • as a non-N-methyl-D-aspartate (NMDA) receptor blocker to study its effects on the heart rate in rats

Biochem/physiol Actions

Potent, competitive AMPA/kainate glutamate receptor antagonist.

Long-term depression (LTD) of synaptic efficacy is widely regarded as a cellular basis of learning and memory. The magnitude of hippocampal CA1 LTD induced by low-frequency stimulation (LFS) declines with age, but the mechanisms involved remain poorly understood. Perineuronal nets

Chronic intermittent hypoxia (CIH), as occurs in sleep apnea, impairs baroreflex-mediated reductions in heart rate (HR) and enhances HR responses to electrical stimulation of vagal efferent. We tested the hypotheses that HR responses to activation of alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) and

The study of human cortical development has major implications for brain evolution and diseases but has remained elusive due to paucity of experimental models. Here we found that human embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), cultured

Oligodendrocyte (OL) maturation and axon-glial communication are required for proper myelination in the developing brain. However, physiological properties of OLs remain largely uncharacterized in different brain regions. The roles of oligodendroglial voltage-activated Na+ channels (Nav) and electrical excitability in relation

Excitotoxicity, a critical process in neurodegeneration, induces oxidative stress and neuronal death through mechanisms largely unknown. Since oxidative stress activates protein kinase D1 (PKD1) in tumor cells, we investigated the effect of excitotoxicity on neuronal PKD1 activity. Unexpectedly, we find
