Is the Ratio of Antibodies Against Oxidized LDL to Oxidized LDL an Indicator of Cardiovascular Risk in Psoriasis?
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...
متن کاملThe preparation of copper-oxidized LDL for the measurement of oxidized LDL antibodies by EIA.
In the present study we try to define the optimal conditions for preparation of copper-oxidized low-density lipoprotein (oxLDL) to be used for the assay of oxLDL antibodies by enzyme immunoassay (EIA). Oxidation of LDL was monitored by measuring the formation of conjugated dienes at 234 nm and the generation of fluorescent products with emission at 430 nm when excitation is performed at 360 nm....
متن کاملDifferential Trafficking of Oxidized LDL and Oxidized LDL Immune Complexes in Macrophages: Impact on Oxidative Stress
BACKGROUND Oxidized low-density lipoproteins (oxLDL) and oxLDL-containing immune complexes (oxLDL-IC) contribute to formation of lipid-laden macrophages (foam cells). It has been shown that oxLDL-IC are considerably more efficient than oxLDL in induction of foam cell formation, inflammatory cytokines secretion, and cell survival promotion. Whereas oxLDL is taken up by several scavenger receptor...
متن کاملMinimally oxidized LDL offsets the apoptotic effects of extensively oxidized LDL and free cholesterol in macrophages.
OBJECTIVE Lipid-loaded macrophage-derived foam cells populate atherosclerotic lesions and produce many pro-inflammatory and plaque-destabilizing factors. An excessive accumulation of extensively oxidized low-density lipoprotein (OxLDL) or free cholesterol (FC), both of which are believed to be major lipid components of macrophages in advanced lesions, rapidly induces apoptosis in macrophages. I...
متن کاملGlyc-oxidized LDL impair endothelial function more potently than oxidized LDL: role of enhanced oxidative stress.
Hypercholesterolemia is associated with impairment of endothelial function due to increased levels of LDL. In diabetic patients, however, attenuation of endothelial function occurs even under normocholesterolemic conditions. Here we assessed whether glycation of LDL potentiates their influence on endothelial function, with particular emphasis on the oxidizability of LDL and the role of O2-. Hum...
