| Research Abstract |
1. The hemagglutation virus of Japan (HVJ)-liposomes were found to be a useful tool for the efficient introduction of macromolecules, including oligodeoxynucleotide, into cultured brain capillary endothelial cells in vitro.
2. Using HVJ-liposomes encapsulating a β-galactosidase gene expression vector, the gene was demonstrated to be efficiently transfered into cultured brain capillary endothelial cells in vitro.
3. The efficient transfer of gene into brain capillary in vivo was achieved by the administration of the HVJ-liposomes encapsulating a β-galactosidase gene expression vector into carotid artery. The expression of β-galactosidase at brain capillaries was found throughout the parenchyma.
4. The above results (2 and 3) indicate that the HVJ-liposome is a useful vector to transfer foreign gene into the brain capillary endothelium in vitro and in vivo.
5. Additional study demonstrated that the cultured mouse brain endothelial cells transfected with mouse glial-derived neurotrophic factor (GDNF) cDNA was found to secrete mature GDNF predominantly to abluminal side (brain side).
