Expression of surface markers in M1 and M2 differentiated MDMs upon uptake of virosomes or liposomes in mono-culture.

<p>Cells in mono-culture were differentiated for 24h into M1 or M2 macrophages before being incubated for 18h with either virosomes (VIRO), liposomes (LIPO) or controls (PBS). Expression of surface molecule markers HLA-DR, CD80, CD86, CD36, CD163 and CD206 were measured by flow cytometry. Figures show the receptor expression in frequency <b>(A)</b> and MFI <b>(B)</b> of six independent experiments. Statistical significance was determined by ANOVA followed by Tukey’s HSD post hoc test to investigate individual paired comparisons. *p<0.05; **p<0.01; ***p<0.001.
