FIGURE 6.

Cell-surface K^b levels are impacted minimally by DRB and AMD treatment. A, L-K^b cells were mock infected or infected with insOVA IAV, then treated with the indicated drugs, and analyzed for surface K^b by flow cytometry. B, Uninfected L-K^b cells or cells infected with insOVA were washed in a cold citric acid buffer to remove existing peptide–MHC complexes from the cell surface and then were cultured with or without indicated inhibitors for specified times. K^b levels on the cell surface were determined by flow cytometry. The mean fluorescence intensity (MFI) of the population analyzed is plotted on the y-axis.
