- Abstract
A bstract: Atherosclerosis is an inflammatory disease induced by a lipid metabolic disturbance at sites of hemodynamic strain in the vasculature. Studies in both man and experimental animal models show an involvement of innate and adaptive immune mechanisms in the disease process. Our recent studies in apoE-knockout mice show that the level of hypercholesterolemia affects the functional properties of the immune response. Modulating immune activity by injections of polyclonal immunoglobulins inhibits disease progression, suggesting that immunomodulation may be useful to treat atherosclerosis. Analysis of T cell receptor (TCR) mRNA in atherosclerotic lesions shows expansions of T cells expressing TCR-Vβ6, a receptor type that is also expressed by T cells recognizing oxidized low density lipoprotein (oxLDL). This suggests that oxLDL is an autoantigen that induces strong, local T cell responses in the plaque. Further characterization of this and other candidate antigens, such as heat shock proteins and macromolecular components of Chlamydia pneumoniae, may provide important information on which specific interference with the disease process could be based.
