Figure Lengend Snippet: Figure 2. PVRL4 and not CD46 is involved in the infection of breast cancer cell lines with rMV-SLAMblind. (a) Surface expression of CD46 and PVRL4 in breast cancer cell lines analyzed by flow cytometry. (Left) Cells incubated with anti-CD46 mouse MAb (gray histogram) or isotype control (white histogram) followed by incubation with Alexa-488-conjugated goat anti-mouse antibody. (Right) Cells incubated with anti- PVRL4 goat polyclonal antibody (gray histogram) or isotype control (white histogram) followed by incubation with Alexa-488-conjugated rabbit anti-goat antibody. (b) Cells were pretreated with anti-CD46 or anti-PVRL4 antibody and infected with rMV-EGFP, rMV-EGFP-SLAMblind or rMV-Edmonston at an MOI of 0.1. Cells were incubated in medium with or without antibody and were photographed at 2 (Vero) or 3 d.p.i. (the others). Cells infected with rMV-Edmonston were immunostained using anti-N rabbit polyclonal antibody. Magnification: 100. (c) CHO- K1 cells were transfected with pCAG-hCD46 or the empty vector (pCAGGS). After 2 days, they were infected with rMV, rMV-SLAMblind or rMV- Edmonston at an MOI of 1 and incubated in the presence of fusion inhibitory peptide. At 2 d.p.i., cells were fixed and immunostained using anti-N MAb and the number of infected cells was counted. Infectivity in cells transfected with pCAGGS was set as 100%. Error bars indicate s.e. *Po0.001 versus pCAGGS. (d) BHK cells were transfected with pCAG-hPVRL4 or pCAGGS. After two days, they were infected with rMV, rMV- SLAMblind or rMV-Edmonston at an MOI of 0.1 and incubated in the presence of fusion inhibitory peptide. At 2 d.p.i., infectivity was determined as described in (c). *Po0.001 versus pCAGGS.

Article Snippet: Infection inhibition assay using antibodies Monolayers of MCF7, MDA-MB-453, SKBR3 and Vero cells in 96-well plates were pretreated for 1 h at 37 1C with medium containing 10mg ml 1 of anti-human CD46 MAb (clone M177; HyCult Biotechnology, Uden, The Netherlands)50 or anti-human PVRL4 goat polyclonal antibody (R&D Systems, Minneapolis, MN, USA).

(b, c) NHDFs were infected with rMV-SLAMblind or rMV-Edmonston at an MOI of 1. (b) Cells fixed and immunostained with anti-N MAb at 3 d.p.i. Magnification: 100. (c) Cell viability measured at each time point by WST-1 assay.

Figure Lengend Snippet: Fig. 1. Infection of the parental, nectin4-expressing, and SLAM-expressing Vero cells with wild-type CDV strains. (A) Vero/hNectin4 (left panel) and Vero/dNectin4 (right panel) cells were stained with a goat anti-human nectin4 polyclonal antibody (gray empty profile) or a control goat IgG (filled black profile), followed by staining with Alexa Fluor 488-conjugated anti-goat IgG. (B) Vero, Vero/ hNectin4, Vero/dNectin4, Vero/hSLAM, and Vero.DogSLAMtag cells were infected with wild-type CDV strains (Ac96I-VDS, 82Con, 55L, M24Cr, and Th12) or mock- infected. At 48 h (Vero, Vero/hNectin4, Vero/dNectin4, and Vero/hSLAM) or 24 h (Vero.DogSLAMtag) post-infection, the cells were stained with the Giemsa solu- tion, and observed under a phase-contrast microscope. (C) Replication kinetics of Ac96I. Vero/hNectin4, Vero/dNectin4, and parental Vero cells were infected with Ac96I at a MOI of 0.01. At various time intervals post-infection, the virus titers were determined by plaque assays.
