Abstract

Abstract : Dementia with Lewy bodies (DLB) is characterized by neuronal deficits and α -synuclein inclusions in the brain. Ceftriaxone (CEF), a β -lactam antibiotic, has been suggested as a therapeutic agent in several neurodegenerative disorders for its abilities to counteract glutamate-mediated toxicity and to block α -synuclein polymerization. By using manganese-enhanced magnetic resonance imaging (MEMRI) and immunohistochemistry, we measured the effects of CEF on neuronal activity and α -synuclein accumulation in the brain in a DLB rat model. The data showed that CEF corrected neuronal density and activity in the hippocampal CA1 area, suppressed hyperactivity in the subthalamic nucleus, and reduced α -synuclein accumulation, indicating that CEF is a potential agent in the treatment of DLB.
