Abstract

Expression of Gi-coupled designer receptors exclusively activated by designer drugs (DREADDs) on excitatory hippocampal neurons in the hippocampus represents a potential new therapeutic strategy for drug-resistant epilepsy. During my talk I will demonstrate that we obtained potent suppression of spontaneous epileptic seizures in mouse and a rat models for temporal lobe epilepsy using different DREADD ligands, up to one year after viral vector expression. The chemogenetic approach clearly outperforms the seizure-suppressing efficacy of currently existing anti-epileptic drugs. Besides the promises, I will also present some of the challenges associated with a potential chemogenetic therapy, including constitutive DREADD activity, tolerance effects, risk for toxicity, paradoxical excitatory effects in non-epileptic hippocampal tissue.
