title: Upregulation of EHD2 after intracerebral hemorrhage in adult rats.
abstract: EHD2, a member of the Eps15 homology domain (EH domain) family, is important for protein interactions during vesicular trafficking. Previous studies have proved that EHD2 can regulate trafficking from the plasma membrane in the process of endocytosis. However, its function in central nervous system diseases is still with limited understanding. In this frame, we found that EHD2 expression was upregulated in the perihematomal caudate in adult rats after intracerebral hemorrhage (ICH). Double immunofluorescence staining revealed that EHD2 was colocalized with neurons and activated microglias after ICH. Besides, we detected that neuronal apoptosis markers (TUNEL and caspase-3), and microglial activation marker (CD68), also known as a marker of macrophage, were colocated with EHD2. The vitro study also indicated that EHD2 was linked with neuronal apoptosis and microglial phagocytosis. All our findings suggested that EHD2 might be involved in the pathophysiology of ICH.
