Activation of group III metabotropic glutamate receptors (mGluR4, mGluR6, mGluR7, and mGluR8) has been established to be neuroprotective in vitro and in vivo. To disclose the identity of the receptor subtype(s) that exert(s) the protective effect, we have used group III agonists in combination with mGluR4 subtype-deficient mice (-/-). In cortical cultures(More)
Group III metabotropic glutamate receptors (mGluRs) are thought to modulate neurotoxicity of excitatory amino acids, via mechanisms of presynaptic inhibition, such as regulation of neurotransmitter release. Here, we describe (R,S)-4-phosphonophenylglycine (PPG) as a novel, potent, and selective agonist for group III mGluRs. In recombinant cell lines(More)

Two splice variants of the human metabotropic glutamate receptor 7, named hmGluR7a and hmGluR7b, were isolated from a human brain cDNA library. The isoforms differ by an out-of-frame insertion of 92 nucleotides close to the C-terminus of the hmGluR7 coding region, hmGluR7a has a length of 915 amino acids and represents the human homolog of the recently(More)
We have used potent and selective non-competitive antagonists of metabotropic glutamate receptor subtype 5 (mGlu5) -- 2-methyl-6-phenylethynylpyridine (MPEP), [6-methyl-2-(phenylazo)-3-pyridinol] (SIB-1757) and [(E)-2-methyl-6-(2-phenylethenyl)pyridine] (SIB-1893) - to examine whether endogenous activation of this particular metabotropic glutamate receptor(More)
A cDNA encoding the human metabotropic glutamate receptor type 4 (hmGluR4) was isolated from human brain cDNA libraries by cross-hybridization with rat mGluR4 probes. The deduced amino acid sequence of human mGluR4 consists of 912 residues and shows a sequence identity of 96% to the amino acid sequence of rat mGluR4. Northern blot analyses indicate that(More)
The effects of dopamine D1 and D2 receptor agonists and antagonists on the rate of GABA synthesis in four regions of mouse brain (corpus striatum, cerebellum, cortex and hippocampus) were examined after irreversible inhibition of 4-aminobutyrate: 2-oxoglutarate aminotransferase (EC 2.6.1.19; GABA-T) by gabaculine. The dopamine D2 receptor agonists PPHT, LY(More)
This study compares the effect of using tangible robots to using visual representations for introducing seventh graders (12 to 13 year old) to computer programming. The impact was measured on learning outcome, self-efficacy, class feedback and attitudes towards STEM (science, technology, engeneering and mathematics) topics. Results show that using robots to(More)
Programmable robots like Lego Mindstorms have proven to be an effective mediator to teach computer programming to school children. Therefore several projects that aim at increasing the interest in computer programming and computer science in general use robots as a cornerstone in their course concepts. Handing out robotic kits to the school students who(More)
