Abstract: Induction of immune tolerance to ox-LDL could reduce atherosclerosis by modulation immune response. We suppose that very low density lipoprotein (VLDL) may have a similar role to ox-LDL in autoimmune response of atherosclerosis. In this study, neonatal rats were injected with ox-LDL, VLDL, or equal-volume saline, respectively. Vaccination with ox-LDL reduced the level of specific antibody, T cells proliferation response, and the level of endothelins. The method also had a tendency of reducing blood lipids. Vaccination with VLDL obviously reduced the level of specific antibody and T cells proliferation. Though there was also a tendency of reducing blood lipids and endothelins, the effect was less prominent than that with ox-LDL. We conclude that, although the effect was less obvious, vaccination with VLDL to induce neonatal tolerance had an effect on modulating immune response, protecting endothelial cells, and reducing blood lipids.
