Virology: HIV goes nuclear

Min Li1 & Robert Craigie1

HIV-1 replicates itself by integrating into its host cell's DNA. Studies in cell culture reveal that nuclear-membrane proteins aid engagement of the viral DNA with that of its host before integration.

Rather than going to the trouble of replicating its own genome, human immunodeficiency virus type 1 (HIV-1) inserts a DNA copy of its genome into that of its host so that the virus is reproduced during host-cell division (Fig. 1).
