SR ligands modulate DEP endocytosis. MDDC were preincubated for 15 min with 20 and 100 μg/ml dextran sulfate or maleylated ovalbumin and then, DEP (10 μg/ml) was added. After 6 h incubation, side scatter (SSC) of MDDC was analyzed by flow cytometry. Data are expressed as the difference between the SSC in DEP-stimulated and inactivated cells. The data reported the mean ± SEM from 5 independent experiments. ✻: p < 0.05 compared with cells with DEP alone (medium).
