Outline of Final Research Achievements |
In this study, we observed that heparan sulfate (HS) and chondroitin sulfate (CS) were degraded in ischemic brain lesion. In addition, increased level of heparanase 1 (HPSE1), hyaluronidase (HYAL1) and HYAL4 were observed. When low molecular weight of heparin and CS together with N-acetylcysteine (NAC), a free radical scavenger were administrated to photochemically induced thrombosis model mice, infarct area was decreased compared with NAC only group. These results suggest that not only oxidative stress but also degradation of HS and CS in glycocalyx of endothelial cells are important for the ischemic brain infarction.
