Human immunodeficiency virus (HIV-1) uses CD4 as the Mechanism of Transdominant primary receptor and chemokine co-receptors to enter target Inhibition of CCR5-mediated cells (1). Chemokine receptors belong to the superfamily of G protein-coupled receptors that have seven transmembrane do- HIV-1 Infection by ccr5D32* mains. Chemokines are a family of small proteins (7–16 kDa) that can be operationally divided in two subgroups. The a (Received for publication, August 27, 1997) subfamily (CXC) is distinguished from the b subfamily (CC) by Monsef Benkirane‡§¶, Dong-Yan Jin‡, the insertion of a single amino acid between the first and the Rene F.
