β‐Hydroxybutyrate reduces neuronal excitability via GIRK channels

Epilepsia, EarlyView.
β‐Hydroxybutyrate decreases neuronal excitability by activating GIRK channels through HCAR2 signaling, providing a cellular mechanism that may contribute to the antiseizure effects of the ketogenic diet. Abstract Objective The ketogenic diet is used to treat drug‐resistant epilepsy, yet the molecular mechanisms coupling metabolic state to seizure ...
