Cell-to-Cell Spread of Dengue Viral RNA in Mosquito Cells

Figure 6

Viral synapse formation at the site of cell-cell contact. The results of DENV E protein detection by immunofluorescent assay (IFA) revealed that viral products may accumulate at the site of cell contact (arrow) at 18 hpi (a) and form an evident viral synapse (arrow) at 24 hpi (b). Green: DENV E protein; blue: DAPI-stained nucleus.
