Lipoprotein uptake and LPL activity in Atgl^−/− and WT macrophages. MPM from WT and Atgl^−/− mice were incubated with [³H]VLDL (A) or [³H]acLDL (B) for 24 h. VLDL and acLDL uptake in Atgl^−/− and WT MPM was assessed by liquid scintillation. C, WT and Atgl^−/− MPM were incubated with [³H]triolein for 1 h and assayed for LPL activity. Data are presented as mean values (n = 3–5) performed in duplicate ± S.E. *, p < 0.05.
