Excitatory amino acid transporter 2 (EAAT2) is the major glutamate transporter and functions to remove glutamate from synapses. An increase in EAAT2 protein expression and function may provide a means to prevent insufficient glutamate reuptake and consequently reduce neuronal damage.

The glial glutamate transporter EAAT2 plays a major role in glutamate clearance. EAAT2 can be upregulated by transcriptional or translational activation.EAAT2 is a potential target for the prevention of excitotoxicity.
