Although the existence of an immune response against modified lipoproteins in atherosclerosis has been observed in experimental animals as well as in humans, the precise pathophysiological relevance of these findings remains unclear. In this study we determined the effect of an immunization with homologous LDL and copper-oxidized LDL on the formation of atherosclerotic plaque in hypercholesterolemic rabbits. Immunizations were performed at the start of a cholesterol-rich diet and 3 weeks later. After 16 weeks, antibodies against oxidized LDL had developed in rabbits given hypercholesterolemic diet alone, but the titers were increased by twofold in rabbits immunized with oxidized LDL as well as in rabbits immunized with LDL, suggesting that the LDL had also become oxidized during the preparation and/or immunization procedure. Immunization with LDL and oxidized LDL reduced atherosclerotic lesions in the proximal aorta by 74% (P < .05) and 48% (P = NS), respectively. The cellular composition of the lesions was not affected by the immunizations. These results support the hypothesis that an immune response against modified LDL has a protective effect against the development of early atherosclerotic lesions.
