HDL₂ and apo A-I mediated ¹⁴C-cholesterol efflux from peritoneal macrophages. Macrophages isolated from peritoneal cavity of trained (n = 7 - black bars) and sedentary (n = 7 - white bars) C57BL/6N wild type mice, after 48 h the last exercise session, were enriched with acetylated LDL and ¹⁴C-cholesterol 30 h. The ¹⁴C-cholesterol efflux was determined, after 8 h and 24 h, of incubation with HDL₂ (panel a) and apo A-I (panel b). ¹⁴C-cholesterol efflux was calculated as (¹⁴C-cholesterol in the medium/¹⁴C-cholesterol in cells plus medium) × 100. Data are expressed as mean values ± standard deviation
