Abstract
The entry of primate immunodeficiency viruses into target cells depends on a sequential interaction of the gp120 envelope glycoprotein with the cellular receptors, CD4 and members of the chemokine receptor family. The gp120 third variable (V3) loop has been implicated in chemokine receptor binding, but the use of the CCR5 chemokine receptor by diverse primate immunodeficiency viruses suggests the involvement of an additional, conserved gp120 element. Through the use of gp120 mutants, a highly conserved gp120 structure was shown to be critical for CCR5 binding. This structure is located adjacent to the V3 loop and contains neutralization epitopes induced by CD4 binding. This conserved element may be a useful target for pharmacologic or prophylactic intervention in human immunodeficiency virus (HIV) infections.

) - We cotransfected 293T cells with 20 μg of a plasmid expressing the wtΔ or mutant envelope glycoproteins and 2 μg of a plasmid expressing the HIV-1 Tat protein using the calcium phosphate technique. Transfected cells were washed and metabolically labeled for 16 hours with [ 35 S]cysteine (50 μCi/ml) and [ 35 S]methionine (50 μCi/ml). Labeled cell supernatants were harvested cleared by low-speed centrifugation (200 g for 10 min at 4°C) and stored at 4°C until used in the binding assays. For measurement of the binding of sCD4 and antibodies to the wtΔ and mutant envelope glycoproteins different dilutions of the envelope glycoprotein–containing supernatants were precipitated to ensure that binding occurred in the linear range of the assay. For CD4 binding the envelope glycoprotein–containing supernatants were incubated for 30 min at room temperature with a concentration of sCD4 (SmithKline Beecham) empirically determined to precipitate the wtΔ protein optimally. The envelope glycoprotein–sCD4 complexes were then precipitated with the CD4-specific antibody OKT4 (Ortho) and protein A–Sepharose (Pharmacia). For binding of the 17b and F105 antibodies the monoclonal antibodies were incubated with protein A–Sepharose before overnight incubation with envelope glycoprotein–containing supernatants at 4°C. For binding of the CG10 antibody envelope glycoprotein–containing supernatants were incubated with 100 nM sCD4 at room temperature for 30 min before addition of a CG10–protein G–Sepharose mixture and overnight incubation at 4°C. Immunoprecipitates were washed and run on 12.5% SDS-polyacrylamide gels which were fixed dried and analyzed by autoradiography. Binding was quantified by densitometry. To measure CCR5 binding we mixed envelope glycoprotein–containing supernatants with 100 nM sCD4 or phosphate-buffered saline (PBS) and incubated them at room temperature for 30 to 60 min. L1.2-CCR5 cells [2 × 10 7 cells LeukoSite (3)] were pelleted resuspended in 500 μl of envelope glycoprotein–containing supernatants and rocked gently at 37°C for 1 hour. Cells were pelleted washed twice in PBS and lysed by the addition of NP-40 buffer (0.5 M NaCl 10 mM tris pH 7.5 0.5% NP-40). Lysates were cleared (20 000 g at 4°C for 15 min) in a microcentrifuge and the envelope glycoproteins were precipitated overnight at 4°C by a mixture of sera from HIV-1–infected individuals and protein A–Sepharose. Sepharose pellets were washed in NP-40 buffer boiled in SDS-containing sample buffer and run on 12.5% SDS-polyacrylamide gels. Autoradiographed gels were quantitated with a densitometer.
