Colocalization between Rab27a and viral glycoproteins in the TGN. HOG cells cultured in DM and infected at a m.o.i. of 1 with wild-type HSV-1 were fixed and processed for confocal triple-label indirect immunofluorescence analysis with polyclonal anti-Rab27a and anti-TGN-46 antibodies. Low panels, corresponding to confocal slices of 0.8 μm, are enlargements of the squares shown in upper panels, which correspond to the projection of the planes obtained by confocal microscopy. Colocalization between gD and the TGN appears yellow; between Rab27a and the TGN, magenta; between Rab27a and gD, cyan. Arrow points to colocalization of Rab27a with gD in the TGN.
