Baculoviruses are safe and high-capacity vectors for gene delivery which have matured from the initial successful experiments performed in liver cells into convenient tools to transduce almost any cell from any origin in vitro and ex vivo. This is a result of 15 years of intensive vector development as well as studies performed in vertebrate cells to reveal important factors affecting the transduction efficacy. Now, at the stage when the first evidence of meaningful use of baculoviruses for therapeutic applications has been reported, there is no doubt that the technology will meet the expectations as highly useful platform for many applications of gene delivery. This review summarizes the pre-clinical in vivo work carried out with baculoviruses and discusses remaining challenges which still need to be solved.
Baculoviruses are widely encountered in nature and a great deal of data is available about their safety and biology. Recently, these versatile, insect-specific viruses have demonstrated their usefulness in various biotechnological applications including protein production and gene transfer. Multiple in vitro and in vivo studies exist and support their use as gene delivery vehicles in vertebrate cells. Recently, baculoviruses have also demonstrated high potential in RNAi applications in which several advantages of the virus make it a promising tool for RNA gene transfer with high safety and wide tropism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
