Accessibility of galactosyl ceramides to probe reagents in central nervous system myelin.

abstract：:The neurotransmitter glutamate, once released into the synaptic cleft, is largely recycled by the glutamate-glutamine cycle, which involves uptake into astrocytes, conversion into glutamine and subsequent release of glutamine from astrocytes as a precursor for neuroneal glutamate synthesis. We analysed glutamine efflu...
