Abstract
Nanocomplex for targeted repairing of neurovascular lesion. The nanocomplex comprises a lipid, an apolipoprotein and a targeted peptide, the targeted peptide formed by covalently linking, through a bridge structure, a nanocarrier linking end and a peptide chain targeting RAGE, which specifically binds to cerebrovascular lesion site. Based on AD and the high expression of RAGE in cerebrovascular and brain parenchyma in diabetic encephalopathy, the nanocomplex, as modified by the targeted peptide, can mainly bind, in a targeted manner, to cerebrovascular endothelium by linking the targeted peptide, to repair vascular endothelial cells, promote removal of Aβ plaque near blood vessels, and repair cerebrovascular and neurovascular unit components such as microglial cells, astrocytes and neurons. Ameliorating cognitive impairment is achieved by combined repairing of multiple components and restoring cerebrovascular functions and cerebral blood flow. The nanocomplex has a disease repair effect and can carry drugs, which are delivered to cerebrovascular lesion site.
