LC were left untreated, stimulated by LPS, exposed to HPV16 VLP, or exposed to HPV16 VLP and subsequently treated with each of the imidaziquinolines. After the final incubation LC were either, A, harvested and analyzed for the expression of CCR7 (black line) by flow cytometry (grey line is the isotype control antibody), or B, used in a migration assay. The mean ± SEM of three separate experiments is presented (***P< .001).
