title: Determinants for lentiviral infection of non-dividing cells.
abstract: Lentiviruses share the common characteristic of infecting non-dividing target cells, distinguishing them from the oncogenic retroviruses which only productively infect dividing cells. The search for determinants for infection of non-dividing cells has produced a number of candidates. From HIV-1, the viral proteins matrix, integrase and Vpr have all been implicated. A structural determinant, the central DNA flap, has also been implicated. The supporting evidence for each of these proposed determinants will be examined and compared to how other viruses, non-retroviruses, transport their genomes to the nucleus. With currently available data, integrase and the central DNA flap appear to be the key players, and yet the mechanism for infection of non-dividing cells remains undefined.
