Vector transduction mimics the HIV-1 entry process and is therefore a safe tool to study HIV-1 entry. Results: Using FLY cells, which express the MLV gag and pol genes, we generated stable producer cell lines that express the HIV-1 envelope gene and a retroviral vector genome encoding the green fluorescent protein (GFP). The BH10 or 89.6 P HIV-1 Env was expressed from a bicistronic vector which allowed the rapid selection of stable cell lines. A codon-usage-optimized synthetic env gene permitted high, Rev-independent Env expression. Vectors generated by these producer cells displayed different sensitivity to entry inhibitors. Conclusion: These data illustrate that MLV/HIV-1 vectors are a valuable screening system for entry inhibitors or neutralizing antisera generated by vaccines."}],"date_updated":"2026-08-07T12:29:10Z","extern":"1","author":[{"first_name":"Sandra","last_name":"Siegert","id":"36ACD32E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8635-0877","full_name":"Siegert, Sandra"},{"last_name":"Thaler","first_name":"Sonja","full_name":"Thaler, Sonja"},{"first_name":"Ralf","last_name":"Wagner","full_name":"Wagner, Ralf"},{"first_name":"Barbara","last_name":"Schnierle","full_name":"Schnierle, Barbara"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","language":[{"iso":"eng"}],"oa_version":"None","citation":{"ista":"Siegert S, Thaler S, Wagner R, Schnierle B. 2005.
