Mission Statement

Type 2 Diabetes has become an epidemic in the United States. Cardiovascular disease is the most common cause of death in this population and is two to four fold higher than the general population. This increased risk is at least partially attributable to the high prevalence of the metabolic syndrome with its multiple coronary heart disease risk factors including central obesity, hypertension, glucose intolerance, chronic inflammation, and dyslipidemia. However, recent trials have demonstrated that traditional risk factors alone are not completely predictive of disease burden particularly early in the disease process prior to the development of flow-limiting coronary stenoses. Diagnosis and prevention of cardiovascular disease development has, thus, been elusive in this high risk population. It is not entirely clear which factors, known or novel, contribute the most in very early disease and which therapies may be most beneficial.


Collaborations

Drs. Coleen McNamara and Angela Taylor have teamed with Dr. Lynn Hedrick on a multi-year NIH Funded Program Project Grant (PPG) titled "Immune Cells in Atherosclerosis and Vascular Disease".

Dr. McNamara's project titled, "B-1A Lymphocytes in Atherosclerosis" hypothesizes that Id3 in B cells is necessary for B-la cell atheroprotection through promoting B-la cell cycle progression and self-renewal resulting in increased levels of atheroprotective natural antibodies such as E06. This hypothesis and the molecular and cellular mechanisms mediating these effects will be studied in aims 1 and 2. Moreover, they will translate these novel findings in mice into testable hypotheses in humans with type 2 diabetes (T2DM). Through collaborations with projects 1 and 2 and our human core, we are uniquely poised to test these innovative hypotheses to identify molecular mechanisms regulating atheroprotective B cells in mice and humans, potentially leading to identification of novel biomarkers and novel strategies to bolster innate immune protection against atherosclerosis.

Dr. Taylor, along with Dr. McNamara, are managing the Human Phenotyping and Immune Cell Core. The function of Core is to provide human and immune cell phenotyping for each project that will be critical to the translation of mechanistic findings into the human model.

The effects of immune cell variations on atherosclerosis in humans represents a poorly understood area of atherogenesis and possible atheroprotection. The goal of the Human Phenotyping and Immune Cell Core (Core B) is to provide the resources necessary for translation of novel immune mechanisms of atherosclerosis that are well defined in murine models into the human model.
