AB - Successful gene therapy aims to deliver and express therapeutic genes to cure or slow the progression of disease. However, a major obstacle in the application of gene therapy has been the development of the vectors used to deliver heterologous DNA to the cell or tissue of choice. A number of viral- and non-viral-based vector systems have undergone clinical trials with varying success. However, at present, no vector system possesses the full complement of properties that are generally believed necessary in an ideal gene delivery system. Therefore, alongside attempts to improve current gene delivery vectors, the identification and evaluation of new viral vectors is crucial for the long-term success of gene therapy. Herpesviruses are large DNA viruses which possess a number of advantages as gene delivery vectors. These relate to an ability to package large DNA insertions and establish lifelong latent infections in which the genomic material exists as a stable episome. This review aims to highlight the potential of herpesvirus vectors, in particular an alternative vector system based on herpesvirus saimiri (HVS). HVS is capable of infecting a range of human cell lines with high efficiencies, and the viral genome persists as high copy number, circular, non-integrated episomes which segregate to progeny following cell division. This allows the virus-based vector to stably transduce a dividing cell population and provide sustained transgene expression for an extended period of time both in vitro and in vivo. Moreover, the insertion of a bacterial artificial chromosome cassette into the HVS genome simplifies the incorporation of large amounts of heterologous DNA for gene delivery. These properties offer characteristics similar to an artificial chromosome combined with an efficient delivery system and merit its continual development as a possible gene delivery vector for the future.
