EAAT2 (also known as Glutamate Transporter-1, GLT-1) as well as EAAT1, is expressed predominantly in glia cells, while EAAT3, EAAT4 and EAAT5 are mostly expressed in neurons.nAs mentioned earlier, EAAT transporters represent the only (significant) mechanism for removal of glutamate from the extracellular fluid and hence are essential for the long-term maintenance of low and non-toxic concentrations of glutamate and the preservation of normal excitatory synaptic transmission.nIn addition to Glu uptake, the glutamate transporters provide glutamate for the synthesis of γ-Aminobutyric acid (GABA), glutathione and protein, suggesting an interactive role between EAATs and cellular metabolism.nDysregulation of EAAT activities has been implicated in several neurodegenerative disorders such as Alzheimer’s disease, traumatic brain injury, epilepsy and schizophrenia, suggesting that EAATs can be a useful target for the treatment of these conditions.
