Abstract excerpt
High density lipoprotein (HDL)-associated paraoxonase-1 (PON1) anti-atherogenic properties in macrophages, i.e. inhibition of cell-mediated oxidation of low density lipoprotein (LDL) and stimulation of cholesterol efflux, were studied using recombinant variants of PON1 and apoA-I expressed in Escherichia coli and reconstituted HDL (rHDL) particles composed of phosphatidylcholine/free cholesterol (PC/FC) and...
