Figure 5From: Yellow fever virus envelope protein expressed in insect cells is capable of syncytium formation in lepidopteran cells and could be used for immunodetection of YFV in human seraE protein structural and ultrastructural analysis of vSynYFE-infected insect cells. Tn5B cells were infected with vSynYFE (10 pfu/cell) and at 72 h p.i., the cells were photographed in a light microscope and processed for electon microscopy. Multinucleated syncytial Tn5B cells were easily observed by light (A) and electron microscopy (B). Bar in (A) = 14 μm and in (B), 5 μm. Arrows indicates cells nuclei.Back to article page
