Infection with the recombinant MV with the F protein lacking the cytoplasmic tail (IC323-EGFP-FΔ30). SLAM- and nectin 4-negative Vero (A) and IMR-32 (B) cells were infected with IC323-EGFP or IC323-EGFP-FΔ30 at an MOI of 0.1. At 72 h after infection, EGFP fluorescence in infected cell monolayers was observed under a fluorescence microscope. Representative images are shown. (C) Spread of IC323-EGFP or IC323-EGFP-FΔ30 in the brains of infected hamsters. The brains of euthanized hamsters were observed as described in the legend to Fig. 6. High-sensitivity EGFP images with longer exposure times are also shown.
