Oxidation and scavenger receptor-mediated uptake of low density lipoprotein (LDL) in intimal macrophages are believed to be key events in the development of atherosclerosis. We report here that oxidized LDL increases DNA synthesis, expression of HLA-DR, and interleukin-2 receptors in T cells. The stimulatory effect of oxidized LDL was not due to a direct effect on T cells but required the prese...

antioxidant consumption has been reported to be inversely associated with the incidence of coronary artery disease. to clarify the possible role of vitamin e and volatile oils in the prevention of atherosclerosis, the effects of these compounds on the susceptibility of low-density lipoprotein (ldl) to oxidative modification were investigated. in this study, vitamin e and seven volatile oils “an...

Macrophage or macrophage-derived foam cell death is one of the characteristic events in the development of cell-poor lipid-rich cores of the advanced atherosclerotic plaques. Although the in vivo mechanism for the death of macrophages is unclear, one possible candidate for the agent which induces macrophage cell death is oxidized low density lipoprotein (Ox-LDL). To investigate the mechanism of...

Oxidized low-density lipoprotein (LDL) has been shown to be a powerful regulator of gene expression in monocyte-derived macrophage. To determine the effects of oxidized LDL on macrophage gene expression, macrophages incubated with native or oxidized LDL were analyzed by differential display technique. The differentially expressed cDNA (387 bp) fragment by oxidized LDL showed 100% homology to th...

background: a great deal of evidence has indicated that oxidatively modified ldl plays a critical role in the initiation and progression of atherosclerosis. antioxidants that can prevent ldl oxidation may act as antiatherogens. copper is a candidate for oxidizing ldl in atherosclerotic lesions. the binding of copper ions to ldl is usually thought to be a prerequisite for ldl oxidation by copper...

introduction this paper proposes the concept of autonomous drug-encapsulated nanoparticle (adenp) as a novel non-invasive approach to prevent atherosclerosis. adenp consists of three simple units of sensor, controller (computing), and actuator. the hardware complexity of adenp is much lower than most of the nanorobots, while the performance is maintained by the synergism in the swarm architectu...

the non-enzymatic carbamylation of low density lipoprotein (ldl) is a naturally occurring chemical modification of apolipoprotein b as a result of condensation between lysine residues and cyanate derived from urea. carbamylated ldl is poorly recognized by ldl receptors and initiates different processes that can be considered proatherogenic. thus, ldl carbamylation may contribute to the increase...
