Cannabidiol (CBD) enhancement of cloned human Kv7.2/7.3 channel current in Chinese hamster ovary (CHO) cells.

(A) hKv7.2/7.3 current evoked by staircase depolarizations before and after application of 100 nM CBD. (B) Collected results (mean ± SEM) for current at –50 mV after application of 100 nM (n = 20) …

Cannabidiol (CBD) enhancement of M-current in mouse sympathetic neurons.

(A) Currents evoked by hyperpolarizations to –60 mV, –70 mV, and –80 mV from a holding potential of –30 mV before (blue) and after (red) application of 100 nM CBD. (B) Collected results (mean ± SEM) …

Cannabidiol (CBD) enhancement of Kv7 current in rat hippocampal neurons.

(A) Currents at a holding voltage of –30 mV and during a 500 ms hyperpolarization to –50 mV in control, after application of 1 μM CBD, and after addition of 3 μM XE-991 in the continuing presence of …
