Fig. (4) Effect of Resiquimod on BAFF and APRIL expression by MEC-1 cells. MEC-1 cells were incubated overnight in the presence of medium alone (Control, left part) or with Resiquimod 1 µM(right part) and the membrane expression of BAFF and APRIL was estimated as before by flow cytometry. The percentages of positive cells were estimated by Kolmogorov-Smirnov analysis. The Δ MFI are indicated in brackets and the differences between control and Resiquimod-treated cells are significant for the two markers. Results are from one experiment out of two that gave comparable results.
