Abstract

Although the biogenic amine models have provided meaningful links between clinical phenomena and pharmacological management of with mood disorders (MDs), the onset of action of current treatments is slow and a proportion of individuals fail to adequately respond. A growing number of investigations have focused on the glutamatergic system as a viable target. Herein we review the putative role of N-methyl-D-aspartate (NMDA) signaling in the pathophysiology of MDs. Prompting this focus are several lines of evidence: 1) altered glutamate and NMDA receptor (NMDAR) expression and functioning; 2) antidepressant effects of NMDAR signaling blockers; 3) interaction between conventional therapeutic regimens and NMDAR signaling modulators; 4) biochemical evidence of interaction between monoaminergic system and NMDAR signaling; 5) interaction between neurotrophic factors and NMDAR signaling in mood regulation; 6) cross-talk between NMDAR signaling and inflammatory processes; and 7) antidepressant effects of a number of NMDA modulators in recent clinical trials. Altogether, these studies establish a warrant for the refinement of novel compounds that target glutamatergic mechanisms for the treatment of MDs.
