ABSTRACT
Intracerebral hemorrhage is the bleeding caused by spontaneous non-traumatic rupture of blood vessels in brain parenchyma. It has high disability rate and mortality. A series of injuries after intracerebral hemorrhage will lead to neuronal apoptosis. If apoptotic neurons are not cleared in time, intracellular toxic substances will be released, thereby further aggravating the inflammatory reaction. Therefore, the timely clearance of apoptotic cells is of great significance to the brain homeostasis after intracerebral hemorrhage. At the same time, a large number of phagocytic "eat me" signal phosphatidylserine (PS) will appear on the surface of apoptotic neurons. Microglia, as resident macrophages in the brain, have a variety of PS receptors on their surface, which promote the phagocytosis of apoptotic neurons by microglia and reduce the occurrence of local inflammatory responses.
