On the Physicochemical and Structural Modifications Associated with HIV-1 Subtype B Tropism Transition.

abstract：:The silent period that follows infection by the human immunodeficiency virus (HIV-1) and precedes seroconversion remains a problem for the screening of blood supply, and knowledge about the mechanism involved in the maintenance of latency is only fragmentary. Using purified nef recombinant protein and six synthetic ne...
