Descriptive Information
Brief Title  ICMJE Role of Immune System in Obesity-related Inflammation and Cardiometabolic Risk
Official Title  ICMJE Role of Immune System in Obesity-related Inflammation and Cardiometabolic Risk
Brief Summary The purpose of this study is to learn more about how the body stores fat in and around organs (for example in the liver) and why this affects some people's health more than others. Understanding this may lead to better treatments for diseases such as diabetes and cardiovascular disease.
Detailed Description The purpose of this study is to determine the specific cellular and organ system metabolic and immunologic alterations that are associated with insulin resistance and inflammation in order to identify putative mechanisms and novel bio-markers involved in the pathogenesis and progression of inflammatory and cardiometabolic diseases.
