RNA-mediated inhibition of HIV in a gene therapy setting.

At present, treatment for HIV-1 infection employs highly active anti-retroviral therapy (HAART), which utilizes a combination of RT and protease inhibitors. Unfortunately, HIV can escape many therapies because of its high mutation rate and the complexity of its pathogenesis. HIV-1 integrates into the cellular genome, which facilitates persistence and acts as a reservoir for reactivation and replication. As an alternative or adjuvant to chemotherapy we have been developing an RNA-based gene therapy approach for the treatment of HIV-1 infection. This article summarizes the various RNA based technologies that we have developed for potential application in a gene therapy setting.
