Antinociceptive actions of honokiol and magnolol on glutamatergic and inflammatory pain

Journal of Biomedical Science, 2009
The antinociceptive effects of honokiol and magnolol, two major bioactive constituents of the bark of Magnolia officinalis, were investigated on animal paw licking responses and thermal hyperalgesia induced by glutamate receptor agonists including ...

Determinants of functional coupling between astrocytes and respiratory neurons in the pre-Bötzinger complex. [PDF]

PLoS ONE, 2011
Respiratory neuronal network activity is thought to require efficient functioning of astrocytes. Here, we analyzed neuron-astrocyte communication in the pre-Bötzinger Complex (preBötC) of rhythmic slice preparations from neonatal mice. In astrocytes that

Molecular determinants of positive allosteric modulation of the human metabotropic glutamate receptor 2. [PDF]

Br J Pharmacol, 2015
Background and PurposeThe activation of the metabotropic glutamate receptor 2 (mGlu2) reduces glutamatergic transmission in brain regions where excess excitatory signalling is implicated in disorders such as anxiety and schizophrenia. Positive allosteric modulators (PAMs) can provide a fine‐tuned potentiation of these receptors' function and are being ...

Contribution of Cystine-Glutamate Antiporters to the Psychotomimetic Effects of Phencyclidine [PDF]

, 2008
Altered glutamate signaling contributes to a myriad of neural disorders, including schizophrenia. While synaptic levels are intensely studied, nonvesicular release mechanisms, including cystine–glutamate exchange, maintain high steady-state glutamate ...

Behavioral and Functional Evidence of Metabotropic Glutamate Receptor 2/3 and Metabotropic Glutamate Receptor 5 Dysregulation in Cocaine-Escalated Rats: Factor in the Transition to Dependence [PDF]

Biological Psychiatry, 2010
Rats with extended daily cocaine access show escalating cocaine self-administration and behavioral signs of dependence. Regulation of glutamatergic transmission by metabotropic glutamate receptors has emerged as a mechanism in the addictive actions of drugs of abuse.

Sequences within the C terminus of the metabotropic glutamate receptor 5 (mGluR5) are responsible for inner nuclear membrane localization [PDF]

, 2017
Traditionally, G-protein-coupled receptors (GPCR) are thought to be located on the cell surface where they transmit extracellular signals to the cytoplasm.

N-acetyl-cysteine, a drug that enhances the endogenous activation of group-II metabotropic glutamate receptors, inhibits nociceptive transmission in humans. [PDF]

, 2015
Emerging research seeking novel analgesic drugs focuses on agents targeting group-II metabotropic glutamate receptors (mGlu2 and mGlu3 receptors). N-Acetylcysteine (NAC) enhances the endogenous activation of mGlu2/3 receptors by activating the glial ...

Differential Epigenetic Regulation of Glutamatergic Synapse Pathway in Adults With Prenatal Exposure to Famine. [PDF]

Eur J Neurosci
Using DNA methylation data collected on adults prenatally exposed to the Chinese famine of 1959–1961, this study reports the altered epigenetic regulation in genes of the glutamate synapse pathway in association with early‐life adversity. Our analysis revealed an overall pattern of reduced DNA methylation of the pathway genes that is more pronounced in

Permissive role for mGlu1 metabotropic glutamate receptors in excitotoxic retinal degeneration [PDF]

, 2017
Neuroprotection is an unmet need in eye disorders characterized by retinal ganglion cell (RGC) death, such as prematurity-induced retinal degeneration, glaucoma, and age-related macular degeneration.
