| Outline of Final Research Achievements |
Microglia are immune cell in the brain. Recent studies have shown that microglia contribute to neural circuit formation during developmental stage by contacting synapses. Additionally, microglia suppress excessive excitation of neuron by contacting neural soma. Thus, it maybe postulated that mechanical interactions between microglial process and neurons maybe required for the above mentioned activities. In this study, the function of mechanosensitive channel in microglia was focused on. To examine the function, I tried to regulate the expression of the mechanosensitive channel in microglia using lentivirus. However, the transfer efficiency was not enough to suppress the expression of the channel. Therefore, I created microglia-specific mechanosensitive channel deficient mice using Cre-loxP system. Currently, I am examining the effect of depletion of mechanosensitive channel on microglial morphology and dynamics.
