Following the path of the virus: the exploitation of host DNA repair mechanisms by retroviruses.
Numerous host cellular cofactors are involved in the life cycle of retroviruses. Importantly, DNA repair machinery of infected cells is activated by retroviruses and retroviral vectors during the process of integration and host cell DNA repair proteins are employed to create a fully integrated provirus. The full delineation of these repair mechanisms that are triggered by retroviruses also has implications outside of the field of retrovirology. It will undoubtedly be of interest to developers of gene therapy and will also further facilitate our understanding of DNA repair and cancer. This review gives a brief summary of the accomplishments in the field of DNA repair and retroviral integration and the opportunities that this area of science provides with regards to the elucidation of repair mechanisms, in the context of retroviral infection.
