Serum paraoxonase: effect of the apolipoprotein composition of HDL and the acute phase response

Journal of Lipid Research, 2003
Genetic variations of paraoxonase (PON) correlate with HDL cholesterol and apolipoprotein A-I (apoA-I), suggesting antiatherogenic properties. Atherosclerosis occurs naturally in humans and rabbits but not in mice.
