FIG 6.

Infectivities of pseudotyped VSVs in C-type lectin-expressing cells. K562 cells expressing hMGL or DC-SIGN were infected with VSVΔG*-Zaire, VSVΔG*-Reston, VSVΔG*-Lloviu, VSVΔG*-Angola, and VSVΔG*-Musoke. The infectivity of each pseudotyped VSV on K562 clones was determined by counting the number of GFP-positive cells using flow cytometry, and the percentages of infectivity in K562-hMGL and K562-DC-SIGN were determined by setting the number of the infected K562 cells as 100%. Each experiment was performed three times, and averages and standard deviations are shown. Statistical significance of the differences was determined by Student's t test (see P values in the text).
