While retroviruses generally only infect dividing cells (because their access to the host genome is thought to rely on the breakdown of the nuclear
envelope that occurs in mitosis [Roe et al., 1993]-RRB-, lentiviruses are a genus of the retroviral family that can infect non-dividing cells (possibly through the use of nuclear localization signals by the viral components [Bukrinsky et al., 1992]-RRB-, and thus, offer an advantage when transducing certain cell
types that exhibit limited cell division (e.g., neurons).
