Abstract

Route to fast antidepressants? Antidepressants such as selective serotonin re-uptake inhibitors can take months to take effect, but small doses of ketamine, a glutamatergic N-methyl-D-aspartate receptor (NMDAR) agonist, can have antidepressant effects within hours. The antidepressant mechanism of ketamine is not well understood. Work in mice shows that antidepressant-like effects of ketamine depend on rapid synthesis of brain-derived neurotrophic factor (BDNF). Ketamine-mediated NMDAR blockade deactivates eukaryotic elongation factor 2 (eEF2) kinase, resulting in reduced eEF2 phosphorylation and de-suppression of BDNF translation. These findings raise the possibility of this pathway as a therapeutic target for fast-acting antidepressants.
