Abridged general view. Diabetes upregulated the expression of caveolin-1 and the glycosylation of CD147 in both astrocytes and endothelium and further elevated the activities of MMPs, especially MMP-2/9. Higher MMP activity accelerates the degradation of BBB components and ultimately leads to erythrocyte leakage after rt-PA treatment of acute cerebral ischemia
