Figure 6

Red blood cell components did not affect maturation of dendritic cells. (A, B) To assess the percentage of phagocytosis, uninfected red blood cells (RBC), P. yoelii-infected RBC (iRBC) at the schizont stage and RBC treated with ionomycin (A) or different stages of P. yoelii-infected RBC (B) were labeled with the fluorescent dye CellTrace™ Far Red DDAO-SE, and incubated for 4 h with DC, before analysis by flow cytometry. The grey curve represents control DC that were not incubated with RBC. (C) CD86 expression analyzed by flow cytometry of DC incubated for 24 h with RBC, iRBC, Ionomycin-treated RBC (iono-RBC) and mouse hemoglobin (Hb). (D) CD86 expression analyzed by flow cytometry of DC incubated for 24 h with RBC, iRBC, Ionomycin-treated RBC (iono-RBC) and mouse hemoglobin (Hb), followed by another 18 h incubation with LPS (black bars) or PBS (white bars). Data correspond to the average of triplicate samples ± standard deviation and figures are representative of one out of three independent experiments.
