Abstract

Several neurodegenerative disorders, namely Parkinson's disease dementia, dementia with Lewy bodies, and Alzheimer's disease, share common pathophysiological features, such as (1) cognitive deficits, (2) glutamatergic hyperactivity-related excitotoxicity, and (3) deposition of α-synuclein (α-syn) and β-amyloid (Aβ). Ceftriaxone (CEF) is a well-tested and safe drug that has been used as an antibiotic for several decades. Recent studies have demonstrated the following effects of CEF: (1) increasing glutamate transporter-1 expression and glutamate reuptake and suppressing excitotoxicity, (2) binding well with α-syn and inhibition of α-syn polymerization, (3) modulating expression of genes related to Aβ metabolism, and (4) enhancing neurogenesis and recovery of neuronal density. In addition, our data revealed that CEF ameliorates seizure and abnormal neuronal firing in the brain. These results suggest the potential of CEF in treating neuronal disorders. This paper addresses the effects and pharmacology of CEF.
