ICAM1 and ischemic stroke: To probe the impact of postischemic increase of α-Syn expression and perivascular localization, we assessed the expression of ICAM-1 (intercellular adhesion molecule-1), MMP-9 (matrix metallopeptidase 9), VEGF-A (vascular endothelial growth factor A), and VEGFR-1 (vascular endothelial growth factor receptor 1), which are key genes involved in endothelial activation, immune cell infiltration, basement membrane degradation and vascular permeability after ischemic stroke.
