title: HIV interactions with CD4: a continuum of conformations and consequences.
abstract: Here, Lee Eiden and Jeffrey Lifson present a model for HIV envelope glycoprotein-CD4 interactions that attempts to reconcile recent, seemingly conflicting, structural, biochemical and biological observations. Central to this model is the involvement of both the CDR2-like and CDR3-like domains of CD4 in the interaction with gp120, leading to a conformational change and dissociation of gp120 from the gp120-gp41 complex.
