According to the decades-old neurotrophic hypothesis of depression, the delayed actions of antidepressants are purported to be due to their downstream effects on neuronal plasticity. In a recent study, Casarotto et al. reveal that antidepressants can in fact directly bind to the neurotrophin TRKB receptor and exert their effects through this mechanism.
