Bioactive baculovirus nanohybrids for stent based rapid vascular re-endothelialization.

ABSTRACT: Present study, for the first time, reports the development of a nanohybridized baculovirus based stent that can locally promote vascular re-endothelialization by efficient delivery of pro-angiogenic vascular endothelial growth factor (Vegf) genes. In vitro data demonstrated rapid expression of functionally active Vegf by the bioactive stent-transduced vascular cells. In vivo site-specific transgene expression was observed at the stented regions of balloon-denuded canine femoral artery, which eventually lead to significant endothelial recovery at the injured sites. A significant reduction in neointima formation (2.23 ± 0.56 mm(2) vs 2.78 ± 0.49 mm(2) and 3.11 ± 0.23 mm(2), p < 0.05; n = 8) and percent stenosis was observed in treated stent group compared to negative control and bare metal s
