Expression of CD1 proteins by in vitro-generated lipid-laden foam cells. Cytokine-treated foam cells expressed high levels of CD1a, -b, and -c as assessed by FACS analysis. Cells were stained with antibodies with the specificities indicated at the top of each column. Antibodies used were P3 (nonbinding negative control), OKT6 (anti-CD1a), 4A7.6.5 (anti-CD1b), F10/21A3 (anti-CD1c), and W6/32 (anti-MHC class I, positive control). Further characterization of cytokine-treated foam cells in a separate experiment revealed that these cells expressed the macrophage markers CD11b (Mac1) and complement receptor 1 (CR-1) but expressed only low levels of CD14 when compared to macrophages cultured in medium alone, as shown in Table 1 ▶ .
