Fig. (5) Inhibition of virus replication in HIV target cells by conditionally expressed Cav-1. The LTR-IR-GFP-RRE-IR-Cav-1 construct was placed in the foamy virus vector for transduction of HIV target cells to determine inhibition of virus replication by conditionally expressing Cav-1 in infected cells. Foamy virus vector mediated transductions of positive (SFV/HL-R and SFV/CMV-Cav-1) and negative (pEGFPD and pNL4-3) controls are included for comparisons. Results are expressed as the means ± standard deviations (SD) from three determinations (P < 0.05).
