Immunization of hypercholesterolemic mice with selected apoB-100 peptide antigens reduces atherosclerosis but the precise immune mediators of athero-protection remain unclear. In this study we show that immunization of apoE (-/-) mice with p210, a 20 amino acid apoB-100 related peptide, reduced aortic atherosclerosis compared with PBS or adjuvant/carrier(More)
BACKGROUND It is increasingly evident that CD8(+) T cells are involved in atherosclerosis but the specific subtypes have yet to be defined. CD8(+)CD25(+) T cells exert suppressive effects on immune signaling and modulate experimental autoimmune disorders but their role in atherosclerosis remains to be determined. The phenotype and functional role of(More)
BACKGROUND T cells and macrophages are implicated in the pathogenesis of aortic aneurysm (AA) and atherosclerosis. We recently demonstrated that a vaccine using an apoB-100-related peptide p210 reduces atherosclerosis with favorable modulation of CD8+ T cells in apolipoprotein E-deficient (apoE-/-) mice. OBJECTIVES This study hypothesized that a p210(More)
BACKGROUND The lipid milleu exacerbates the inflammatory response in atherosclerosis but its effect on T cell mediated immune response has not been fully elucidated. We hypothesized that lipid lowering would modulate T cell mediated immune function. METHODS AND RESULTS T cells isolated from human PBMC or splenic T cells from apoE-/- mouse had higher(More)
Recent studies suggest the potential involvement of CD8+ T cells in the pathogenesis of murine hypertension. We recently reported that immunization with apoB-100 related peptide, p210, modified CD8+ T cell function in angiotensin II (AngII)-infused apoE (-/-) mice. In this study, we hypothesized that p210 vaccine modulates blood pressure in AngII-infused(More)
