To investigate the role of T-helper cells/Treg (Th17/Treg) and morbidity factors related to primary nephritic syndrome (PNS) in children, as well as the influence of ox-low density lipoprotein (ox-LDL) on Th17/Treg expression in children with PNS. To clarify the pathogenesis of PNS in children, 50 children with PNS treated in our hospital were enrolled in the study group. Additionally, 20 healt...
Lectin-like oxidized LDL (ox-LDL) receptor-1 (LOX-1) is a type-II transmembrane protein that belongs to the C-type lectin family of molecules. LOX-1 acts as a cell surface endocytosis receptor and mediates the recognition and internalization of ox-LDL by vascular endothelial cells. Internalization of ox-LDL by LOX-1 results in a number of pro-atherogenic cellular responses implicated in the dev...
BACKGROUND Hyperlipidemia inhibits proliferation of endothelial cells (ECs) in culture and angiogenesis in vivo and in arterial explants. Elucidation of the mechanisms may suggest novel therapies against atherosclerosis. METHODS AND RESULTS Basic fibroblast growth factor (bFGF) expression and mitogenic effects were assessed in bovine aortic ECs incubated with oxidized LDL (ox-LDL). Compared w...
We investigated the effect of chronic exposure (3 days) with low-density lipoprotein (LDL) and oxidized (Ox)-LDL on the unstimulated and stimulated formation of prostacyclin (6-keto-prostaglandin [PG]F1 alpha) and total inositol phosphates (IPs) by cultured bovine aortic endothelial cells. Neither basal nor bradykinin-stimulated (1 to 10 nmol/L) formation of 6-keto-PGF1 alpha was affected by LD...
INTRODUCTION In vitro studies have shown that oxidized, low density lipoprotein (ox-LDL) stimulates macrophages to release interleukin-6 (IL-6) and interleukin-1β (IL-1β). In this study, we aimed to investigate the correlation between ox-LDL and IL-6 and IL-1β levels in the peripheral circulation of patients with type 2 diabetes, and normal controls. We measured serum high sensitivity CRP (hs-C...
Native and oxidized (OX) low-density lipoprotein (LDL) may contribute to the pathogenesis of age-related macular degeneration (AMD). In this study, we investigated the effects of lipoproteins, including n-LDL and OX-LDL, on the expression of inflammation factors, interleukin-6 (IL-6) and interleukin-1β (IL-1β), in vivo and in cultured retinal pigment epithelial (RPE) cells. The potential role o...
Accumulating evidence indicates that secretory phospholipase A2 (sPLA2) enzymes promote atherogenic processes. We have previously showed the presence of Group V sPLA2 (GV sPLA2) in human and mouse atherosclerotic lesions, its hydrolysis of low density lipoprotein (LDL) particles, and the ability of GV sPLA2-modified LDL (GV-LDL) to induce macrophage foam cell formation in vitro. The goal of thi...
Oxidized low-density lipoprotein (ox-LDL) is critical to atherosclerosis in hyperlipidemia. Bone marrow (BM)-derived endothelial progenitor cells (EPCs) are important to preventing atherosclerosis, and significantly decreased in hyperlipidemia. This study was to demonstrate ox-LDL and hyperlipidemia could exhibit similar effect on EPC population and the role of reactive oxygen species (ROS). RO...
Glomerulosclerosis frequently complicates most renal diseases and is characterized by mesangial matrix accumulation. Oxidized low-density lipoprotein (Ox-LDL) could induce oxidative stress and profibrotic gene expression in mesangial cells. This article will review our current understanding of the pathogenetic mechanisms of lipid-mediated glomerulosclerosis, emphasizing the fibrogenic signaling...
BACKGROUND Auto-immune responses are associated with oxidized LDL (ox-LDL) release, a key factor in plaque destabilization. Data on the relationship between ox-LDL and T lymphocytes in human populations remains scarce. T cells also react with other molecules from the lesion and/or damage the myocardium. OBJECTIVE The objective of the present study was to examine the relationship between circu...
