Figure 7

Confocal laser scanning microscopy analysis shows the Dil-AcLDL staining on THP-1 monocyte-derived macrophage cells to check the inhibition of foam cell formation. THP-1 monocyte-derived macrophage cells were pre-treated with curcumin-Bioperine PLGA NPs (1:1:10) for 24–72 h, followed by incubation of Dil-AcLDL for 4 h. The top panel (A–D) shows the control THP-1 monocyte-derived macrophage cells forming foam cells (Scale bar 20 μm). The second panel (E–H), third panel (I–L), and fourth panel (M–P) show the inhibition of foam cell formation upon treated with curcumin-Bioperine PLGA NPs 1:1:10 for 24–72 h (scale bar 10 μm).
