title: HIV-1: is Nef a PAK animal?
abstract: HIV-1 Nef is clearly essential for efficient viral replication in vivo, but it has been difficult to determine why. Recent evidence that Nef specifically activates a PAK-dependent signalling cascade may be the first step in defining the mechanism of action of this enigmatic viral protein.
