Phospholipase A2 Mediates Apolipoprotein-Independent Uptake of Chylomicron Remnant-Like Particles by Human Macrophages

Table 1

Biochemical characterization of chylomicron remnant-like lipid particles (CRLP) incubated without (CRLPw/o) or with plasma (CRLP+). Total cholesterol (TCH), triacylglycerol (TG), and free cholesterol (FCH) are expressed as means ± SD (n).
