  • 초록

    Beta-Amyloid ( $A{\beta}$ )-induced neuroinflammation is one of the key events in the development of neurodegenerative disease. We previously reported that KHG21834, a benzothiazole derivative, attenuates $A{\beta}$ -induced degeneration of cortical and mesencephalic neurons in vitro. In the present work, we show that KHG21834 reduces $A{\beta}$ -mediated neuroinflammation in brain. In vivo intracerebroventricular infusion of KHG21834 leads to decreases in the numbers of activated astrocytes and microglia and level of proinflammatory cytokines such as interleukin- $1{\beta}$ and tumor necrosis factor- $\alpha$ induced by $A{\beta}$ in the hippocampus. This suppression of neuroinflammation is associated with decreased neuron loss, restoration of synaptic dysfunction biomarkers in the hippocampus to control level, and diminished amyloid deposition. These results may suggest the potential therapeutic efficacy of KHG21834 for the treatment of $A{\beta}$ -mediated neuroinflammation.
