Abstract Background and Purpose Subsets of midbrain dopamine (DA) neurons express the vesicular glutamate transporter VGLUT2 and can release the excitatory neurotransmitter glutamate. VGLUT2+ DA neurons of the substantia nigra pars compacta (SNc) were shown to be more resistant to neurodegeneration in animal models of Parkinson's disease (PD ...

Metabotropic Glutamate Receptors and Epileptogenesis
Activation of metabotropic glutamate receptors (mGluRs) often produces long-lasting effects on the excitability of cortical neurons. For example, mGluR stimulation induces long-term potentiation or depression of excitatory synaptic transmission in the hippocampus.

Chronic cocaine enhances release of neuroprotective amino acid taurine: a microdialysis study [PDF]
Cocaine inhibits high-affinity neurotransmitter uptake at the presynaptic nerve terminals to increase synaptic levels of dopamine, norepinephrine and serotonin^1^. This increase of synaptic dopamine may cause neurotoxicity^2,3^.

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

Abstract Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2‐3‐fold increase in neuropsychiatric co‐morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ...

Nonheme Fe enzyme isopenicillin N synthase was reprogrammed and evolved as an efficient nitrogen migratase IPNSNim, converting diverse azanyl esters to valuable l‐arylglycines with up to 16 000 TTN and 97:3 e.r. IPNSNim and ACCONim allowed enantiodivergent preparation of both l‐ and d‐arylglycines.

Modulation of the GABAergic pathway for the treatment of fragile X syndrome. [PDF]
Fragile X syndrome (FXS) is the most common genetic cause of intellectual disability and the most common single-gene cause of autism. It is caused by mutations on the fragile X mental retardation gene (FMR1) and lack of fragile X mental retardation ...

Abstract Background and Purpose Pharmacological inhibition of TRPC4 and/or TRPC5 channels reduces Pavlovian aversion memory in stressed mice and reduces amygdala reactivity to aversion in humans with depression. The aims of this mouse study were to improve understanding of these anxiolytic processes, determine whether there are corrective effects on ...

Augmented Cystine–Glutamate Exchange by Pituitary Adenylate Cyclase-activating Polypeptide Signaling via the VPAC1 Receptor [PDF]
In the central nervous system, cystine import in exchange for glutamate through system xc- is critical for the production of the antioxidant glutathione by astrocytes, as well as the maintenance of extracellular glutamate. Therefore, regulation of system

Abstract Objective Absence epilepsy is characterized by brief but frequent seizures with loss of consciousness. Existing treatments, which come with heavy side effects, are only partially effective and do not address the associated comorbidities, including cognitive and social deficits.
