The virus shown in the diagram below is only able to infect and replicate in epithelial cells. In order for the cross-presenting dendritic cell to display viral peptides, rather than self peptides on its surface MHC class I proteins, which of the following procedures could be utilized, starting with the components shown in the figure below?
Mix epithelial cells with heat-killed virus, wait 24 hrs, wash away any virus particles outside the epithelial cells, then add epithelial cells to dendritic cells.
Mix epithelial cells with viral peptides, wait 24 hrs, wash away any viral peptides not bound to the epithelial cells, then add epithelial cells to dendritic cells.
Mix epithelial cells with live virus particles, wait 24 hrs, wash away any virus particles outside the epithelial cells, then add epithelial cells to dendritic cells.
