Mechanisms of Vascular Stiffness

Increased vascular stiffness has been identified as an important cardiovascular event that accompanies aging and cardiovascular disease. Although multiple vascular changes have been identified and suggested to cause increased vascular stiffness, our understanding of the underlying mechanisms needs to be refined in order to develop useful therapeutic strategies to prevent or reverse these changes. An example of critical ...more »

Goal 2: Reduce Human Disease

The Use of Therapeutic Apheresis to Reduce Circulating Levels of Galectin-3 and other Cancer and Inflammation Promoting Factors

Inflammation plays roles in cancer initiation, promotion, and progression. Elevated circulating galectin-3 (Gal-3) protein and other cancer and inflammation promoting factors (CIPFs) such as C-reactive protein and VEGF are associated with tumorigenesis and may play causative roles. Plasma Gal-3 is a biomarker, prognosticator, and pathogenic mediator of diverse cancers and is emerging as a therapeutic target. Preliminary ...more »

Assess the true impact of sickle cell trait on cardiovascular health across then age spectrum

Sickle cell disease is now understood as a disease of inflammation in addition to abnormal red blood cells. It is likely persons with sickle cell trait are also negatively affected by the damage caused by inflammation. There is a significant racial disparity in hypertension, stroke, and chronic kidney disease. It remains unclear the degree to which sickle cell trait contributes to this disparity. It also remains unclear ...more »

The Human Virome and Host Interactions in Heart, Lung, and Blood

What are the unknown elements of the human virome, and what host-virome interactions affect the heart, lung, and blood health and diseases? A major challenge has been the need for in vitro culture systems and animal models for studying the virome, which is a significant limitation that has forced current studies of the virome to be mostly descriptive. NHLBI has supported one research group to identify human virome and ...more »

Impact of lung remodeling on congestive heart failure progression

End stage congestive heart failure (CHF) causes intensive lung remodeling beyond the type-2 pulmonary hypertension. CHF induced lung remodeling includes profound lung fibrosis, lung vascular remodeling and lung inflammation. Understanding CHF-induced lung remodeling is also critical to understand the right ventricular failure. However, this area is largely unstudied. Regulating CHF-induced lung remodeling and the underlying ...more »

Modulation of cardiac contraction and relaxation in heart failure: role of systemic inflammation

Is cardiac contraction and relaxation in heart failure modulated by the systemic inflammatory response? There is overwhelming evidence that inflammatory biomarkers predict worse outcome in acute and chronic heart failure. Despite the wealth of evidence, clinical trials in this area have either not been completed, failed, or provided inconclusive results. The questions that remain are: 1) Is inflammation a mechanism ...more »

Goal 3: Advance Translational Research

Develop Targeted Therapeutics to Treat Venous Thrombosis and Inflammation in Venous Thromboembolism

Venous Thromboembolism (VTE) afflicts nearly a million Americans yearly, has a mortality of 6-12% and has costs of more than $15 billion. Current treatment regimens, systemic anticoagulation and compression stockings, fail patients in multiple ways: risk of major bleeding episodes; failure of clot resolution in up to 50% of patients; failure to prevent the development of post-thrombotic syndrome (PTS) in up to 40% of ...more »

Targeting Inflammation in Venous Thromboembolism

What is the role of inflamation in venous thromboembolism, both DVT and PE. If the inflammatory response can be controlled, then clot formation should be able to be decreased or eliminated without bleeding potential. The effect of the inflammatory response on the wall of the veins, both in the legs and the lungs, leads to changes that result in pain and swelling (legs) and pulmonary artery hypertension (lungs). Inhibiting ...more »

Goal 2: Reduce Human Disease

What is the role of chronic inflammation in lung complications in the HAART era?

With the advent of HAART HIV-infected subjects are living longer. Lung infectious complications so common in the early stages of the HIV epidemic have been replaced by those associated with chronic inflammation (COPD, pulmonary hypertension, lung cancer). Furthermore, this chronic inflammation is likely contributing to premature vascular complications (i.e coronary disease) seen in this population. All of these complications ...more »
