Abbreviations are: ApoAI, apolipoprotein AI; C, free cholesterol; FFA, free fatty acids; HDL, high density lipoproteins. ABCAI and ABCG1 are ATP-binding cassette transporters A1 and G1, respectively. The large cell illustrates an adipocyte containing a large unilocular lipid droplet. Monocytes and macrophages are illustrated as small grey cells with dark circular nuclei.
