ApoE-/- mice immunized with native p210-PADRE develop p210-specific IgG1 antibodies and less atherosclerosis. ApoE-/- mice were immunized with native p210-PADRE or PADRE peptide. IgG1 (a, c, e) and IgG2c (b, d, f) antibodies against p210 (a, b), p210-PADRE (c, d), or PADRE (e, f) (plasma dilution 1:1000) from immunized mice were analyzed in ELISA. Atherosclerotic plaque formation was analyzed in the aortic arch (g) and in subvalvular plaques (h). Macrophage (i), collagen (j), lipid (k), and MDA-LDL (l) content were analyzed in subvalvular plaques. Data are depicted as individual mice, with bars indicating median (IQR) (af) or mean ± SD (gk). *p < 0.05, **p < 0.01, ***p < 0.001; Mann–Whitney test (af) or Unpaired t-test (gl).
