Abstract Background Nef is an accessory protein of primate lentiviruses HIV-1 HIV-2 and SIV. Besides removing CD4 and MHC class I from the surface and activating cellular signaling cascades Nef also binds GagPol during late stages of the viral replicative cycle. In this report we investigated further the ability of Nef to facilitate the replication of HIV-1. Results To this end first the release of new viral particles was much lower in the absence of Nef in a T cell line. Since the same results were obtained in the absence of .
