Abstract: The current study showed that potassium K current ( I K), which is evoked at depolarizing potentials between −30 and +40 mV in cultured hippocampal neurons, was significantly reduced by exposure to the CB1 cannabinoid receptor agonist WIN 55,212-2 (WIN-2). WIN-2 (20–40 nM) produced an average 45% decrease in I K amplitude across all voltage steps, which was prevented by SR141716A, the CB1 receptor antagonist. The cannabinoid receptor has previously been shown to be Gi/o protein-linked to several cellular processes; however, the decrease in ...
