Grape seed proanthocyanidin extract inhibits glutamate-induced cell death through inhibition of calcium signals and nitric oxide formation in cultured rat hippocampal neurons

BMC Neuroscience, 2011
Background Proanthocyanidin is a polyphenolic bioflavonoid with known antioxidant activity. Some flavonoids have a modulatory effect on [Ca2+]i. Although proanthocyanidin extract from blueberries reportedly affects Ca2+ buffering capacity, there are no ...

Estrogenic regulation of hippocampal inhibitory system across lifespan

Journal of Neuroendocrinology, EarlyView.
Abstract Estrogens produced in peripheral tissues and locally in the brain are potent neuromodulators. The function of the hippocampus, a brain region essential for episodic memory and spatial navigation, relies on the activity of ensembles of excitatory neurons whose activity is temporally and spatially coordinated by a wide diversity of inhibitory ...

Neuroprotection and Functional Recovery Associated with Decreased Microglial Activation Following Selective Activation of mGluR2/3 Receptors in a Rodent Model of Parkinson's Disease

Parkinson's Disease, 2010
Clinical trials have demonstrated positive proof of efficacy of dual metabotropic glutamate receptor 2/3 (mGluR2/3) agonists in both anxiety and schizophrenia.

Clozapine Normalizes a Glutamatergic Transmission Abnormality Induced by an Impaired NMDA Receptor in the Thalamocortical Pathway via the Activation of a Group III Metabotropic Glutamate Receptor

Biomolecules, 2019
Pharmacological mechanisms of gold-standard antipsychotics against treatment-refractory schizophrenia, such as clozapine (CLZ), remain unclear. We aimed to explore the mechanisms of CLZ by investigating the effects of MK801 and CLZ on tripartite synaptic

Membrane progesterone and oestrogen receptors modulate GABAergic transmission in the prefrontal cortex of prepubertal male, but not female, mice

Experimental Physiology, EarlyView.
Abstract The sex hormones progesterone (P) and oestrogen (E) reorganize GABAergic transmission in the prefrontal cortex (PFC) during the transition from childhood to adolescence, generating a new excitatory–inhibitory balance necessary for the computational capacity of the mature PFC.

Non‐ionotropic NMDAR signalling activates Panx1 to induce P2X4R‐dependent long‐term depression in the hippocampus

The Journal of Physiology, EarlyView.
Abstract figure legend Stimulation of the Shaffer collateral pathway at 3 Hz activates non‐ionotropic NMDA receptors. This subsequently leads to Src kinase mediated phosphorylation of pannexin‐1 (Panx1), which releases ATP from the postsynaptic cell. ATP acts as a ligand for P2X4 receptors to induce long‐term depression (LTD). Abstract In recent years,

Dual role for pannexin 1 at synapses: regulating functional and morphological plasticity

The Journal of Physiology, EarlyView.
Abstract figure legend Pannexin 1 (PANX1) regulation of dendritic spines. The postnatal decrease in PANX1 expression could release key spine cytoskeleton‐regulating proteins enabling spine stabilization. Does the physiological decrease in neuronal PANX1 levels across brain development underlie dendritic spine maturation?

Accuracy of direct gradient sensing by cell-surface receptors [PDF]

arXiv, 2009
Chemotactic cells of eukaryotic organisms are able to accurately sense shallow chemical concentration gradients using cell-surface receptors. This sensing ability is remarkable as cells must be able to spatially resolve small fractional differences in the numbers of particles randomly arriving at cell-surface receptors by diffusion.

Stimulation of microglial metabotropic glutamate receptor mGlu2 triggers tumor necrosis factor alpha-induced neurotoxicity in concert with microglial-derived fas ligand [PDF]

, 2005
Activated microglia may be detrimental to neuronal survival in a number of neurodegenerative diseases. Thus, strategies that reduce microglial neurotoxicity may have therapeutic benefit.
