Pharmacology and toxicology of astrocyte-neuron glutamate transport and cycling

J Pharmacol Exp Ther. 2002 Apr;301(1):1-6. doi: 10.1124/jpet.301.1.1.

Abstract

The interaction between astrocytes and neurons is examined from the standpoint of glutamate neurotoxicity. The review details 1. the distribution of glutamate transporters on astrocytes and neurons, provoking a reformulation of the interdependence between these two cell types in removing extracellular glutamate and preventing excitotoxic injury; 2. the potential involvement of aberrant glutamate transporter function in the etiology of neuropathological conditions; 3. the role of astrocyte-neuron interaction in widely divergent aspects of brain energetics; 4. the role of astrocytes in the process of glutamate recycling within the context of anesthetic treatment with pentobarbital and thiopental.
