Possible involvement of receptors in the entry of Kunjin virus into Vero cells.
The results obtained from electron microscopy, adsorbed and internalised virus assays and immunofluorescence studies supported that the most likely mode of entry of Kunjin virus into Vero cells was by receptor-mediated endocytosis. This was deduced indirectly from the time sequence of events that occurred. Electron microscopy revealed that endocytosis of the virus through coated vesicles had occurred. The adsorbed and internalised virus assay and immunofluorescence studies showed that there were two factors being recycled during endocytosis: the receptor for the virus and clathrin, the protein found on coated pits and vesicles. The study showed that clathrin was recycled first, followed by the receptor.
