Outline of Final Research Achievements |
I have focused on the mechanisms of the neurodegenerative disease. Especially, the relation between Ab toxicity and neuronal homeostatic plasticity is the most important issue in this work. Ab is the well-known molecule for the cause of Alzheimer’s disease. After hippocampal primary culture got network activity, Ab was applied to the culture media. Ab has no acute effect on the cultured neuron activity. In several days, though, Ab diminished the presynaptic size both of excitatory and inhibitory synapse. Network activity is not changed at 37C, but changed at 28C. These results indicate temperature-sensitive homeostatic plasticity rescued from the toxicity of Ab in the experimental condition. In addition, BDNF might completely eliminate the toxicity of Ab, so there was no network activity change.
