WitrynaHuman immunodeficiency virus type 1 (HIV-1) based gene transfer systems are gaining in popularity due to their ability to transduce terminally differentiated and non-dividing cells. Oncoretroviral vectors based on Moloney murine leukemia virus (MoMLV), on the other hand, can only transduce dividing cells. The reasons for increased ability of ... WitrynaThis strategy is first focused on driving HIV hidden in human immune cells to make viral proteins that allow the cells with HIV to be recognised (Induce). Once cells harbouring HIV are exposed, drugs can then tag these reservoir cells for elimination by the host immune system (Reduce). The Induce and Reduce agents will all be given while …
