The Effects Of Environmental Ozone Exposure On Vascular Function, Oxidative Stress, And Atherosclerosis, Gin Chuang Jan 2010

The Effects Of Environmental Ozone Exposure On Vascular Function, Oxidative Stress, And Atherosclerosis, Gin Chuang

Exposure to air pollutants are known to induce airway inflammation, decrease lung function, and worsen existing pulmonary conditions such as asthma. Additionally, air pollutant exposure has also been shown to impact cardiovascular health. Although these pollutant-induced cardiovascular effects were considered to be mediated by the direct action of pollutants upon the cardiovascular tissue and/or the indirect release of pro-inflammatory factors into the circulation, the relative contribution of the two pathways remained equivocal. Recently, several epidemiology studies associated ozone exposure with cardiovascular mortalities. However, relatively few studies to date have examined ozone in this context. In order to address our hypothesis …


Roles Of Adiponectin And Its Receptors In Foam Cell Transformation, Ling Tian Jan 2010

Roles Of Adiponectin And Its Receptors In Foam Cell Transformation, Ling Tian

Macrophages play a critical role in the initiation and progression of atherosclerosis by producing pro-inflammatory mediators and transforming into lipid-laden foam cells. The prevention of lipid accumulation and inflammation in macrophage foam cells, therefore, represents a promising target for effective therapy for atherosclerosis. Adiponectin is a circulating cytokine primarily expressed and secreted by adipocytes, and is downregulated in obesity-linked diseases including type 2 diabetes, coronary artery disease and hypertension. In oxidized low-density lipoprotein (oxLDL)-induced human THP-1 macrophage foam cells, adiponectin suppresses lipid accumulation through decreasing lipid uptake and increasing high-density lipoprotein (HDL)-mediated lipid efflux. The potential mechanisms that adiponectin utilizes …
