Recently it has been shown that levels of circulating oxidized LDL immune complexes (ox-LDL-ICs) predict the development of diabetic retinopathy (DR). This study aimed to investigate whether ox-LDL-ICs are actually present in the diabetic retina, and to define their effects on human retinal pericytes versus ox-LDL. In retinal sections from people with type 2 diabetes, costaining for ox-LDL and ...
We examined the effects of human low density lipoprotein (LDL) and oxidized LDL (Ox-LDL) on the cytotoxic activity of Asp-hemolysin from Aspergillus fumigatus Fresenius-Muramatsu strain to mouse peritoneal macrophages (M phi). The inhibitory effects of LDL and Ox-LDL on the cytotoxic activity of Asp-hemolysin to M phi increased in a dose-dependent manner, and the effect of Ox-LDL was greater th...
Oxidized low density lipoprotein (Ox-LDL) induces apoptosis in vascular smooth muscle cells (VSMCs), which may increase atherosclerotic plaque instability. In this study, we examined the molecular mechanisms causing the Ox-LDL-induced apoptosis in VSMCs, especially focusing on the involvement of Bax/Bcl-2 and the lectinlike Ox-LDL receptor-1 (LOX-1). In cultured bovine aortic smooth muscle cell...
The early atherosclerotic lesion is comprised of foam cell macrophages filled with cholesteryl ester (CE), unesterified cholesterol (UC), and cholesterol oxides. Upon incubation of macrophages with oxidized low density lipoprotein (Ox-LDL), they accumulate UC rather than CE, which was shown to accumulate after incubation of cells with acetylated LDL (Ac-LDL). Using lipoproteins that were doubly...
A specific lectin-like endothelial receptor for oxidized low density lipoprotein (LOX-1), distinct from the scavenger receptor in monocytes/macrophages, has been identified and cloned. In this study, we examined the regulation of LOX-1 by oxidized low density lipoprotein (ox-LDL) and determined the role of LOX-1 in ox-LDL-induced apoptosis of cultured human coronary artery endothelial cells (HC...
BACKGROUND We demonstrated earlier that angiotensin II (Ang II), by AT(1) receptor activation, upregulates oxidized LDL (ox-LDL) endothelial receptor LOX-1 gene expression and uptake of ox-LDL in human coronary artery endothelial cells (HCAECs). In this study, we investigated the regulation of Ang II receptors (AT1R and AT2R) by ox-LDL and the role of the redox-sensitive transcription factor NF...
A specific lectinlike endothelial receptor for oxidized low density lipoprotein (LOX-1), distinct from the scavenger receptor in monocytes/macrophages, has been identified and cloned. In this study, we examined the regulation of LOX-1 by oxidized low density lipoprotein (ox-LDL) and determined the role of LOX-1 in ox-LDL–induced apoptosis of cultured human coronary artery endothelial cells (HCA...
atherosclerosis is a chronic inflammatory condition that affects the arterial wall. oxidized low- density lipoprotein (ox-ldl) seems to have an important role in atherosclerotic plaque formation. this study was performed to investigate the effects of ox-ldl as well as pha on proliferation and gene expression of peripheral blood mononuclear cells (pbmcs) in patients with atherosclerosis compa...
Vascular calcification is associated with significant cardiovascular morbidity and mortality, and has been demonstrated as an actively regulated process resembling bone formation. Oxidized low density lipoprotein (Ox-LDL) has been identified as a regulatory factor involved in calcification of vascular smooth muscle cells (VSMCs). Additionally, over-expression of recombinant human neutral sphing...
OBJECTIVES Psoriasis is a chronic inflammatory skin disease. Chronic inflammation results in increased oxidative stress and oxidizes lipoproteins, increasing their atherogenicity. This study sought to estimate the levels of oxidized low-density lipoprotein (ox-LDL) and antibodies against oxidized LDL (anti-ox-LDL) and compute the ratio of anti-ox-LDL/ox-LDL as a single composite parameter to as...
