PURPOSE To determine the role of lectin-like oxidized low-density lipoprotein receptor 1 (LOX-1) in corneal epithelial cells exposed to fungus. METHODS Thirteen corneas with fungal keratitis composed the experimental group. Ten healthy donor corneas were the control group. Corneal epithelium was scraped and LOX-1 mRNA tested. Immunostaining was used to detect LOX-1 protein. Human corneal epit...

Lectin-like oxidized low-density lipoprotein (LDL) receptor-1 (LOX-1), a cell surface receptor expressed in endothelial cells, is known to mediate oxidized LDL-induced vascular inflammation and atherogenesis. Although the role of LOX-1 in vascular inflammation has been well established, its involvement in acute lung inflammation and injury remains unclear. In the present study, we examined the ...

Lectin-like oxidized low-density lipoprotein receptor (LOX-1) has been cloned from human aortic endothelial cells, and has a sequence identical to that from human lung. Previous studies showed that human LOX-1 can recognize modified LDL, apoptotic cells and bacteria. To further explore the relationship between the structure and function of LOX-1, a mutagenesis study was carried out. Our results...

Preeclampsia is a hypertensive disorder unique to pregnancy, in which the placenta may release factors into the maternal circulation resulting in systemic effects. Small dense low-density lipoprotein (LDL; which is susceptible for oxidation) is increased in preeclampsia. Lectin-like oxidized LDL receptor-1 (LOX-1) is a receptor for oxidized LDL. However, the expression levels and the regulation...

Cardiovascular disease is the leading cause of death. The disease is due to atherosclerosis which is characterized by lipid and fat accumulation in arterial blood vessel walls. A key causative event is the accumulation of oxidised low density lipoprotein particles within vascular cells, and this is mediated by scavenger receptors. One such molecule is the LOX-1 scavenger receptor that is expres...

Endothelial dysfunction is an early and key determinant of diabetic vascular complications that is elicited at least in part by oxidized LDL (oxLDL). The recent observation that lectin-like oxLDL receptor-1 (LOX-1) expression is increased in the vascular endothelium of diabetic rats suggests a role for LOX-1 in the pathogenesis of diabetic vascular dysfunction. Because postprandial plasma gluco...

1 in their article titled " A new therapeutic approach using a schizophyllan-based drug delivery system for inflammatory bowel disease " recently reported a novel therapeutic approach for inflammatory bowel disease using an innovative delivery system for antisense oligonucleotides (ODNs) that is based on Schizophyllan (SPG), a polysaccha-ride that belongs to the β-(1-3) glucan family. 1 These a...

BACKGROUND C-reactive protein (CRP) is purported to be a risk factor that acts independently of LDL cholesterol in predicting all-cause mortality in patients with ischemic heart disease. Lectin-like oxidized LDL receptor 1 (LOX-1) impairs endothelial function and exacerbates myocardial injury. We recently demonstrated that CRP increased vascular permeability through direct binding to LOX-1. Her...

OBJECTIVE Carbamylated LDL (cLDL) has been recently shown to have robust proatherogenic effects on human endothelial cells in vitro, suggesting cLDL may have a significant role in atherosclerosis in uremia. The current study was designed to determine which receptors are used by cLDL and thus cause the proatherogenic effects. METHODS AND RESULTS In ex vivo or in vitro models as well as in inta...

Glioblastomamultiforme (GBM) is one of the most lethal forms of cancer, with a survival rate of only 13% to 27%within 2 years of diagnosis despite optimal medical treatment. We hypothesize that the presence of a unique IL-13Ra2 decoy receptor prevents GBM apoptosis. This receptor has a high affinity for interleukin13 (IL-13), binds the cytokine, and competitively inhibits the intracellular sign...
