Details on the impact of addressing this CQ or CC :

­The response to vascular injury, whether it be catheter interventions, bypass surgery, or chronic implants, is a reactive process characterized by inflammation, cell proliferation, and fibrosis leading to failure. Better understanding of the mechanisms of vessel remodeling, and restoring homeostasis, is needed to improve prediction, develop and translate new treatments. This remains the leading scientific problem in vascular medicine and surgery. New approaches such as proteomics, lipidomics, molecular imaging offer new opportunities in this realm.

Goal 3: Advance Translational Research

Direct Upregulation of Antioxidant Defenses as a Therapeutic Strategy

Clinical trials involving administration of antioxidants such as vitamin C or vitamin E as therapeutic strategies for cardiovascular diseases associated with oxidant stress have proven to be surprisingly disappointing. A particularly attractive alternative approach is direct upregulation of endogenous antioxidant defenses such as NRF2 via dietary approaches. NRF2 is a master antioxidant and cell protective transcription ...more »

Details on the impact of addressing this CQ or CC :

Direct upregulation of endogenous antioxidant defenses such as NRF2 via dietary approaches will avoid the well known caveats of drug-based approaches such as off target effects and detrimental side effects. Dietary supplements such as Protandim are already available; and beneficial effects of other NRF2 up-regulators such as resveratrol and sulforaphane are beginning to be recognized. The dietary approach is minimally invasive and has high preventative value.

Feasibility and challenges of addressing this CQ or CC :

Addressing this CQ is clearly feasible, as dietary supplements are currently available for humans, and the beneficial effects of foods containing compounds that upregulate the NRF2 system, e.g., broccoli, cauliflower, red wine, and grape juice are currently recognized. One challenge in addressing this question in animal models to date is that the only genetic model lacking NRF2 is a knockout mouse model, which have substantial limitations for in vivo physiological studies due to their small size. However, a recent R21 grant (#1R21OD018309-J. H. Lombard, P.I.) has allowed the development of a NRF2 knockout rat model which is better suited for physiological studies than the mouse model. In addition, the techniques used to develop the NRF2 knockout rat can be applied to multiple disease-sensitized strains, e.g., the Dahl salt-sensitive rat. Fawn Hooded Hypertensive rat, Obese Zucker rat, etc. Similar disease sensitized rodent genetic strains are not available in mice.

Goal 1: Promote Human Health

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 »

Ultimately, addressing this CQ would impact treatment of CV disease, reduce incidence of significant and life threatening CV events and improve quality of life. This area of investigation is relevant to therapeutics and potentially lifestyle changes that will improve CV health and slow CV age related changes linked to disease.

Feasibility and challenges of addressing this CQ or CC :

Current advances in our technologies make it very feasible to address new questions to improve our knowledge of the mechanisms underlying vascular stiffness. Challenges will include developing multi-scale and cross disciplinary strategies that will, by design, facilitate an integrated understanding of the process leading to altered vascular stiffness.

Understanding the Role of the Vasculature in Dementia

Dementia is traditionally grouped into vascular dementia, Alzheimer's dementia, Parkinson's dementia and other causes of dementia. Vascular dementia is generally thought to be a consequence of strokes but there are some recent studies indicating that even Alzheimer's dementia may have a vascular underpinning. Vascular permeability is increased in the early stages of Alzheimer's disease and it is possible that similar ...more »

Details on the impact of addressing this CQ or CC :

The NHLBI could fund programs which enable vascular biologists to collaborate with neuroscientists and neurologists in order to understand whether the vasculature has a causal role in the progression of dementia.

 

 

 

Can interventions that improve vascular function prevent the progression of dementia? Instead of using broad interventions such as statins which affect numerous signaling pathways, vascular biologists could target selected aspects of vascular health such as improving vascular barrier function and vascular regeneration.

 

If these interventions that have been shown to be efficacious in other vascular beds outside of the brain are also effective in the brain, then important new therapies could be developed for dementia which is likely to become one of the leading cause of death in the next decades.

Feasibility and challenges of addressing this CQ or CC :

A key challenge for targeting the brain vasculature will be the blood-brain barrier. Understanding the role of the blood-brain barrier in dementia will be a prerequisite to developing novel vasculature-directed therapies.
