Effect of ART drugs on cholesteryl ester (CE) accumulation in THP-1 foam
cells. CE accumulation was measured in cell lysates of THP-1-derived macrophages
pre-treated with DMSO (−), nelfinavir, saquinavir, ritonavir, maraviroc
(5, 15 and 30 μM), and raltegravir (5 and 30 μM) for 24 hours and
then incubated with AcLDL (50 μg/mL) for additional 48 hours. Drug
treatment was maintained throughout the experiment. Results are shown for 3
independent experiments with 3 technical replicates (n=9). Data are expressed as
mean±SEM.
