摘要
EphB2 affects neuronal cells by altering the dendritic spines. The present study analyzed the neu-roprotective effects of gastrodine by measuring EphB2 expression in rat neural cells cultured in vitro and injured by kainic acid. Gastrodine （12.5, 25, and 50 mg/L） improved morphology in kainic acid-injured neurons, reduced lactate dehydrogenase leakage, decreased neuronal apoptosis, and increased EphB2 expression in neuronal cells. A moderate dose of 25 mg/L gastrodine resulted in the most significant effects. These results suggested that gastrodine suppressed the neurotoxic effects of excitatory amino acids and provided neuroprotection by remodeling neuronal dendritic spines.
