Internalization of Vectorized Liposomes Loaded with Plasmid DNA in C6 Glioma Cells.


PMID 28580488

Abstract

We studied internalization of vector nanocarriers loaded with plasmid DNA into C6 glioma cells. For improving selectivity of plasmid delivery, the liposomes were conjugated with monoclonal antibodies to VEGF and its receptor VEGFR2. Flow cytofluorometry and laser scanning confocal microscopy showed more intensive (more than 2-fold) internalization and accumulation of antibody-vectorized liposomes in C6 glioma cells in comparison with the control (liposomes conjugated with non-specific antibodies and non-vectorized liposomes). Using quantitative analysis of fluorescent signal, we showed that cationic immunoliposomes significantly more effective delivered pCop-Green-N plasmid DNA and ensured effective transfection of C6 glioma cells.
