Figure 5. Uptake of AcLDL by bone marrow-derived macrophages from ApoE ^−/− and ApoE ^−/− Nrf2 ^−/− mice.

Macrophages were incubated with fluorescently-labeled AcLDL for 24 h at 37°C, and AcLDL uptake was assessed by flow cytometry. (A) Representative histograms of fluorescence intensity. (B) Average relative fluorescence intensity of N = 5 mice per group. *p<0.05 by a two-tailed Student's t-test. Values represent mean±SEM.
