Gabapentin increases extracellular glutamatergic level in the locus coeruleus via astroglial glutamate transporter-dependent mechanisms.

Suto T, Severino AL, Eisenach JC, Hayashida KI (2014) Gabapentin increases extracellular glutamatergic level in the locus coeruleus via astroglial glutamate transporter-dependent mechanisms. Neuropharmacology 81C:95-100. doi: 10.1016/j.neuropharm.2014.01.040

Summary: Gabapentin is effective in reducing acute and chronic pain, but the mechanisms by which it works are not well understood. The authors assessed extracellular glutamate levels and glutamate interaction with several different cellular membrane proteins. Rats received a 0.25 μg injection of anti-DBH-SAP (Cat. #IT-03) into the locus coeruleus (LC) in order to deplete noradreline levels. Mouse IgG-SAP (Cat. #IT-18) was used as a control. The gabapentin-induced glutamate increase in the LC was not affected by the lesion, supporting data indicating that gabapentin induces glutamate release from astrocytes to stimulate descending inhibition.
