Evolution of the neurochemical profile consisting of 19 metabolites after 30 mins of middle cerebral artery occlusion was longitudinally assessed at 3, 8 and 24 h in 6 to 8 mu L volumes in the striatum using localized H-1-magnetic resonance spectroscopy at ...
Many different forms of synaptic plasticity have been shown to ultimately modulate the number of AMPA-type glutamate receptors at the synapse. This trafficking involves lateral movements between synaptic and extrasynaptic sites at the neuron surface, as we ...

Digital holographic microscopy (DHM) is a noninvasive optical imaging technique that provides quantitative phase images of living cells. In a recent study, we showed that the quantitative monitoring of the phase signal by DHM was a simple label-free method ...
We report the semisynthesis of a fluorescent glutamate sensor protein on cell surfaces. Sensor excitation at 547 nm yields a glutamate-dependent emission spectrum between 550 and 700 nm that can be exploited for ratiometric sensing. On cells, the sensor di ...
Clathrin-dependent endocytosis is mediated by a tightly regulated network of molecular interactions that provides essential protein-protein and protein-lipid binding activities. Here we report the hydrolysis of the alpha- and beta2-subunits of the tetramer ...

Broad-spectrum N-methyl D-aspartate (NMDA) antagonists, although proposed in therapies for several pathologies including Huntington's disease (HD), can produce dramatic side-effects. Thus, the therapeutic potential of subunit selective NMDA receptor antago ...
Glutamate and its receptor N-methyl-D-aspartate receptor (NMDAR) have been associated with cancer, although their functions are not fully understood. Herein, we implicate glutamate-driven NMDAR signaling in a mouse model of pancreatic neuroendocrine tumori ...
The present invention concerns a new pharmaceutical composition comprising an antagonist and a co-agonist of the N-methyl-D-aspartate-type glutamate receptor (NMDAR). The inventors found that the co-administration of these two compounds effectively inhibit ...
Obtaining high resolution 3D quantitative images is critical for elucidating the relationship between cell dynamics and physiological or pathological processes. However the feasibility of such cellular dynamic studies is limited by the resolution of the 3D ...
