Selectins, especially E- and P-selectins are upregulated and mediate leukocyte rolling and recruitment during the early stages of ischemia [47] Among the immunoglobulin family member, intercellular adhesions molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 have been the most extensively investigated in cerebral ischemia. Here, ICAM1 is linked to ischemia.
