Deletion of the potassium channel Kv12.2 causes hippocampal hyperexcitability and epilepsy

We show here that the voltage-gated K(+) channel Kv12.2 is a potent regulator of excitability in hippocampal pyramidal neurons. Genetic deletion and pharmacologic block of Kv12.2 significantly reduced firing threshold in these neurons. Kv12.2(−/−) mice displayed signs of persistent neuronal hyperexc...

description We show here that the voltage-gated K(+) channel Kv12.2 is a potent regulator of excitability in hippocampal pyramidal neurons. Genetic deletion and pharmacologic block of Kv12.2 significantly reduced firing threshold in these neurons. Kv12.2(−/−) mice displayed signs of persistent neuronal hyperexcitability including frequent interictal spiking, spontaneous seizures and increased sensitivity to the chemoconvulsant pentylenetetrazol.
