FIG 1.

Transfer of cellular and viral components between cells through different types of cell connections. (A) Direct cell junctions; (B) thick cellular bridge; (C) tunneling nanotube. MDBK cells were infected with BoHV-1-VP26-GFP (green) and stained with MitoTracker red to visualize mitochondria (red). Yellow arrows indicate the main direction of viral transfer. See also Movies S1 and S2 in the supplemental material. Images and time-lapse movies were obtained using a Nikon PCM2000 confocal microscope.
