Abstract

Glutamine (Gln) is abundantly expressed in the central nervous system (CNS), where it participates in a variety of metabolic pathways. Gln metabolism proceeds via the glutamine/glutamate (Glu)-γ-aminobutyric acid (GABA) cycle (GGC), and the reactions within this cycle are carried out both in astrocytic and neuronal compartments. The GGC appears to have an important, albeit not exclusive role, in the recycling of Glu and GABA. Disruption of GGC between astrocytes and neurons contributes to changes in Glu-ergic and/or GABA-ergic transmission, and is associated with several neuropathological conditions, including manganese (Mn) toxicity.
