and purpose: Alzheimer's disease (AD) is a progressive neurodegenerative disorder, and Ab-induced neuronal damage is the major pathology of AD. There is increasing evidence that neuroinflammation induced by Ab is also involved in the pathogenesis of AD. Fasudil is a Rho kinase inhibitor and has been reported to have neuroprotective effects. In this study, the main purpose is to investigate whether fasudil has beneficial effects on cognitive impairment and neuronal toxicity induced by Ab.

Administration of fasudil significantly ameliorated the spatial learning and memory impairment, attenuated neuronal loss, and neuronal injury induced by Ab 1-42 . In addition, fasudil inhibited IL-1b and TNF-a production and NF-jB activation in the rat brain. Conclusions: Fasudil can protect against Abinduced hippocampal neurodegeneration by suppressing inflammatory response, suggesting that fasudil might be a promising agent for the prevention and treatment of inflammation-related diseases, such as AD.
