Evidence demonstrated that glial cells, mainly astrocytes, regulate glutamate uptake, which is regulated by several glutamate transporters. Among these glutamate transporters, glutamate transporter 1 (GLT-1; its human homolog is excitatory amino acid transporter-2) is responsible for the majority of glutamate uptake by glial cells. Cystine-glutamat...
