the possibility that infectious agents may trigger a cascade of reactions leading to inflammation, atherogenesis and vascular thrombotic events has recently been raised. chlamydia pneumoniae is an infectious agent that has received the most attention with respect to coronary artery disease (cad). to determine the relationship between c. pneumoniae and cad, a case control study was conducted on ...

Oxidatively modified lipoproteins have been implicated in atherogenesis, but the mechanisms that promote oxidation in vivo have not been identified. Myeloperoxidase, a heme protein secreted by activated macrophages, generates reactive intermediates that oxidize lipoproteins in vitro. To explore the potential role of myeloperoxidase in the development of atherosclerosis, we determined whether th...

This article reviews aspects of the molecular pathology of cholesteryl ester accumulation in atherosclerotic lesions. 1. Transcytosis of lipoproteins through cultured endothelial monolayer. 2. Transformation to foam cell from macrophage. 3. Cholesteryl ester deposition in the extracellular space of atherosclerotic lesions. We also discuss the development and use of novel monoclonal antibodies r...

BACKGROUND Apolipoprotein (apo) A-I and apoA-I-mimetic peptides showed promise to prevent atherosclerosis development. Using a bypassed vein graft model in apoE-null mice, we evaluated the effects of oral or intraperitoneal administration of an apoA-I-mimetic peptide on evolving atherosclerotic lesions in the vein graft and compared such effects on the established atherosclerotic lesions in aor...
