Fig. 4.

Detailed analysis of a fusion pore. (A–C) Surface renderings of the volume from Fig. 3B in different orientations (see Movie S3 for complete tomogram). (A) Rendering of the virus with parts of the synaptosomal plasma membrane in the same orientation as in the tomographic slice shown in Fig. 3B and Movie S3. (B) The virus was rotated vertically for ≈60° to allow a better view into the fusion pore. (C) Cut-away view of all features apart from the capsid; the orientation was changed to provide a perpendicular view of the pore. Colors used are light blue (capsid), orange (tegument), yellow (glyco proteins), dark blue (viral membrane), and red (cell membrane). Cellular elements of the synaptosome were excluded from rendering for clarity. (Scale bar, 100 nm.)
