11. In microglia , P2X 7 receptors are found mostly on the cell surface. 12. Astrocytes and microglia cells digest the decaying organelles and dying neurons through phagocytosis. 13. Some cells are then phagocytosed by astrocytes and microglia . 14. Microglia are recognized as the innate immune cells of the central nervous system.15. Acute inflammation in the brain is typically characterized by rapid activation of microglia . 16. They present clusters of activated microglia in otherwise normal-appearing white matter. 17. Cells were also labelled in green for Coronin 1a, a marker for microglia . 18. When activated, microglia will secrete proteases, cytokines, and reactive oxygen species. 19. While in their activated state, microglia may serve a variety of beneficial functions. 20. Unlike astrocytes and microglia , oligodendrocytes undergo a much more limited reaction to injury.
