To determine whether targeted in vivo upregulation of the potassium channel gene Kcna1 using CRISPR activation (CRISPRa) can suppress neuronal hyperactivity, attenuate seizures, and reverse cognitive deficits in a rodent model of epilepsy.
Delivered a doxycycline-inducible CRISPRa system targeting the Kcna1 promoter via adeno-associated virus (AAV9) into hippocampal excitatory neurons of a mouse model of temporal lobe epilepsy.
Evaluated network activity, seizure frequency, and severity using continuous video-EEG telemetry alongside assessments of cognitive behavior and transcriptomic changes.
CRISPRa-mediated upregulation of Kv1.1 substantially decreased hippocampal neuronal excitability.
Doxycycline-induced CRISPRa expression significantly reduced spontaneous generalized tonic-clonic seizures and rescued both cognitive impairment and epilepsy-associated transcriptomic alterations.
