Raw EEG data for the paper entitled "Prime editing of the beta1-adrenoceptor in the brain restores physiological REM sleep in a mouse model of Alzheimer's disease"

Abstract: Prime editing offers versatile genome modifications with therapeutic potential; yet its use to modulate neural circuitry remains underexplored. Here, we used adeno-associated viral vectors to deliver prime editors into the mouse brain and introduced the naturally occurring Adrb1A187V variant of the b1-adrenergic receptor, linked to short sleep in humans and mice. Editing reached up to 28.1% in the cortex six months after intracerebroventricular injection and increased excitability of b1-noradrenergic neurons. This enhanced wake-associated behaviors, including home cage activity, locomotion, exploration, and recognition memory, while reducing slow wave activity (SWA) during non-rapid eye movement (NREM) sleep indicating reduced build-up of sleep pressure during active phases. In a mouse model of Alzheimer’s disease, Adrb1A187V installation restored physiological REM sleep and again reduced NREM sleep SWAfollowing spontaneous activity. Together, these findings demonstrate the feasibility of prime editing for reprogramming genetic circuits in the brain and reveal beneficial effects of the Adrb1A187V variant on activity and sleep regulation.
