A new therapeutic direction is emerging from the increased understanding of natural resilience as an active stress-coping process. It is known that potassium (Kþ) channels in the ventral tegmental area (VTA) are an active mediator of resilience. However, no druggable targets have been identified to potentiate active resilience mechanisms. In the chronic social defeat stress model of depression, we report that KCNQ-type Kþ channel openers, including FDA-approved drug retigabine (ezogabine), show …
