Outline of Final Research Achievements |
This research has been aimed to analyze the physiological role of microglia in the developing brain through the maternal IgG and its receptor Fcγ receptor expressed on microglia. As a result, the maternally derived IgG actually flowed into the fetal brain, and also the Fcγ receptors were highly expressed on the surface of microglial especially in the early stage of development. Through the IgG and Fcγ receptor pathway, a large amount of dead cells which are generated during brain development were taken up by the fetal microglia. These results suggested that the fetal microglia might regulate the brain construction physiologically by their phagocytosis function through IgG-Fcγ receptor pathway.
