| Outline of Final Research Achievements |
Activated microglia present at the periphery of cerebral infarction surround and phagocytose degenerating and apoptotic neurons. The mRNAs of MFG-E8, MerTK, Gas6, Protein S, complement (C1q, C3) related to phagocytosis of apoptotic cells of TREM2 and eat-me signal are elevated at the periphery of the cerebral infarction. In the immunohistochemical staining, activated microglia had CD68 positive phagosome and adhered to C3, ProteinS positive Neuron. It was suggested that microglia selectively phagocytizes neurons via these phagocytosis - related molecules, suggesting the possibility of being a target to suppress slow nerve cell death.
