Does retigabine reduce seizures and hippocampal neurodegeneration in a kainic acid-induced seizure model in rats?
Does retigabine reduce seizures and hippocampal neurodegeneration in a kainic acid-induced seizure model in rats?
Retigabine effectively alleviates seizures and hippocampal neurodegeneration in a kainic acid-induced rat seizure model.
Extends preclinical support for RTG in seizures; leaves open human efficacy pending clinical trials.
Aims: The current study evaluates whether Kv7 channel activator retigabine (RTG) could attenuate seizures and hippocampal neurodegeneration in the kainic acid (KA) induced seizure model. Methods: The anticonvulsant activity of RTG is evaluated by electroencephalography (EEG) recordings in KA-kindled rats. Tunel assay and immunofluorescence of NeuN are used to evaluate the neuroprotective effect of RTG in the hippocampus of KA-kindled rats. Results: RTG effectively reduces epileptiform discharges induced by KA injection. Tunel assay and immunofluorescence of NeuN show that RTG exerts neuroprotection in the hippocampus of KA-kindled rats. Conclusion: Taken together, this study demonstrates that RTG effectively alleviates seizures and hippocampal neurodegeneration in the KA-induced seizure model.
