FIG. 5.

PRV virions egress from axons in a gB-independent fashion. PRV GS443, PRV 232 (gB null), and PRV 368 (Us9 null) each express GFP fused to the capsid protein VP26 and were used to infect the S compartments of neuron cultures. Samples were fixed and stained for surface gE antigen (red). Imaging was performed on N-compartment axons. Arrowheads indicate colocalization. The side panels are magnified merge images. Bar, 4 μm.
