We show that isoflurane induced transphosphorylation of TrkB by Src family kinases, stimulates the mTor signaling pathway and promotes neuronal plasticity and antidepressant-like behavior in rodents. Our findings provide a neurobiological basis for the clinically observed antidepressant effects of isoflurane and encourage its further evaluation as a rapid-acting antidepressant treatment devoid of the psychotomimetic side effects of ketamine.
