    EGP expression in target cells enhances EGP/HIV transduction . (A) Cell surface expression of EGP. EGP <t>Tet-On</t> cells were seeded in 12-well plates (6 × 10 4 cells/well) and EGP expression was induced with indicated concentrations of dox. After 24 h post-induction, cell surface EGP levels were analyzed by flow cytometry using an EGP monoclonal antibody. (B) Western blot analysis of EGP expression in Tet-On cells. EGP Tet-On cells were seeded in 12-well plates and induced with indicated concentrations of dox. Forty-eight hours post-induction, cell lysates were subjected to SDS-PAGE followed by immunoblotting using a EGP monoclonal antibody. (C) HIV pseudotyping constructs. HIV packaging construct encodes gag/pol genes required for virion assembly. Envelope expression construct encodes genes for EGP or MGP or VSV-G under the control of a CMV promoter. HIV reporter construct encodes the viral genomic RNA, carrying a luciferase or a GFP reporter gene. (D) Enhancement of EGP/HIV transduction by EGP expression in target cells. EGP or control Tet-On cells were seeded in 24-well plates (3 × 10 4 cells/well) and induced with varying concentrations of dox. After 24 h post-induction, cells were challenged with EGP/HIV, MGP/HIV or VSV-G/HIV pseudovirions carrying a luciferase reporter gene. The luciferase activities in the cell lysates were measured 48 h post-infection and are presented as percentage of the uninduced cells (100%). Data represents an average of at least three independent experiments. Bars, standard deviations. (E) The mucin-like region in EGP is not required for enhancement. Tet-On stable cells with EGP mutant lacking the mucin-like region (ΔEGP) were induced with dox and challenged with pseudotyped virions carrying luciferase reporter. The luciferase activities are shown as relative percentage of the uninduced cells (100%). Data represents an average of at least three independent experiments. Bars, standard deviations. (F) EGP Tet-On cells infected with EGP/HIV pseudovirions carrying a GFP reporter. The percentage of GFP expressing cells, shown in each panel as inserts, were quantified by flow cytometry.

Data represents an average of at least three independent experiments. Bars, standard deviations. (C) Enhancement of EGP/MLV pseudovirus transduction in HeLa Tet-On cells. HEK Tet-On cells with EGP, ΔEGP or control vector induced with dox were challenged with ΔEGP/MLV pseudovirion carrying a GFP reporter. The percentage of GFP expressing cells are shown as inserts in each panel.

    Figure Lengend Snippet: GP enhancement is correlated with the entry susceptibility of the target cells . (A) EGP expression in HeLa cells enhances EGP/HIV transduction. HeLa Tet-On cells with EGP, ΔEGP or control vector were induced with dox and challenged with pseudotyped viruses. The luciferase activities were measured 48 h post-infection and are shown as percentage of the uninduced cells (100%). Data represents an average of at least three independent experiments.

    Analysis of Ebola GP mutants in trans enhancement process . (A) HEK Tet-On cells expressing Wt EGP were challenged with EGP mutant viruses, GP1 mutants, relative infectivity of Wt and GP1 mutant viruses. Fusion peptide mutants, relative infectivity of Wt and fusion peptide mutant viruses. Coiled-coil mutants, relative infectivity of Wt and GP2 mutant viruses. (B) Matrix analysis of trans enhancement by EGP. Wt or mutant EGP expressing HEK Tet-On was either uninduced or induced with 1 μg/ml of Dox. After 24 h, the cells challenged with pseudovirus particles carrying Wt or mutant EGP. The luciferase activities in infected cells are represented as relative percentage of luciferase activity in uninduced cells. Data represents an average of three independent experiments. For clarity of the chart we have omitted the error bars in panel B.
