oxidized phospholipids or oxidized phospholipid-protein adducts inhibit macrophage uptake of oxidized low-density lipoproteins," Journal of Clinical Investigation, vol.

HDL also prevents the formation of oxidized LDL, inactivates
oxidized phospholipids, inhibits monocyteto-macrophage differentiation, and has anti-inflammatory effects on macrophage through inhibition of CD11 activation [7-9].
Navab and colleagues (78) were the first to develop a novel and rapid cell-free assay to determine the ability of HDL to prevent the inactivation or formation of
oxidized phospholipids. This fluorospectroscopic assay quantified the fluorescent signal generated by 2
oxidized phospholipids; oxLDL and oxidized L-[alpha]-1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine.
[sup][27] A deficiency of PON1 enhanced atherosclerosis in hypercholesterolemic mice and was associated with an increase in
oxidized phospholipids. [sup][28] In animals, apoJ levels increase in situations in which PON1 levels decrease.

Recent studies show that
oxidized phospholipids favor monocyte binding to endothelial cells, thus promoting diapedesis from the blood stream [51].
This particle's function remains largely uncertain; Lp(a) binds proinflammatory-oxidized phospholipids (11) and is a preferential carrier of
oxidized phospholipids (ox-PL) in human plasma.
