Enhanced nanoparticle uptake into virus infected cells: Could nanoparticles be useful in antiviral therapy?
In this study, a fluorescently-labelled polymeric nanoparticle was prepared and used to track NP uptake into Huh7.5, human hepatoma cells transfected with replicating HCV genomes, compared with non-transfected cells as a model representing hepatocyte uptake. Confocal microscopy and flow cytometry of virus transfected Huh7.5 cells unexpectedly demonstrated two-fold increase in uptake of NP compared to non-transfected cells. Therefore, virus transfection enhanced NP uptake into Huh7.5 cells and NP could be considered as a promising delivery system for targeted treatment of hepatitis viruses.Graphical abstract
