Nefarious substances in the US blood supply

Prescription and illicit drug is everpresent in the US, which can potentially result in controlled substances entering the US blood supply. Passive transfer of immune allergens is only anecdotally been reported as peanut allergens, fish allergens, and contrast material. However, US blood donors are only screened for a limited number of medications on the universal donor health questionnaire at time of collection. What, ...more »

Improving blood supply by giving a pig a human bone marrow transplant from a universal donor

What do you think of giving a pig a human bone marrow transplant from a universal donor? The pig could produce blood for human use! Although the pig will eventual die of an autoimmune disease its life can be prolonged with all the new autoimmune medicines we have and/or the pig can be engineered to overexpress PDL1 (or a similar autoimmune suppressor). Additionally even if each pint of blood made this way might be ...more »

Goal 3: Advance Translational Research

Tools to facilitate availability and safe use of innovative blood products and their analogs

Novel blood products are being developed based on innovative science (e.g., ex vivo manufactured RBC and platelets, and platelet and plasma derived hemostatic products). However, there is a significant lag in the development of appropriate tools and model systems, which poses a challenge when evaluating such products for regulatory approval.

Biology of Red Blood Cell Alloimmunization

What determines which individuals will develop RBC alloimmune responses resulting in clinically meaningful sequelae? This question encompasses: 1) the generation of alloantibodies that limit the availability of compatible blood or cause hemolytic disease of the fetus or newborn (HDFN); 2) the distinction between clinically significant and insignificant alloantibody responses, especially within alloantibody specificities ...more »

Goal 3: Advance Translational Research

To find specific medical therapies to treat the wide array of human vascular malformations and vascular tumors.

Vascular malformations and vascular tumors, together referred to as vascular anomalies, comprise a complex and wide array of diseases in which there is a fundamental disruption in blood and lymphatic vasculature. The lesions disrupt organ function, destroy tissue, cause bleeding, increase infections and can threaten life. At present, there are some medical therapies but none are specifically targeted to an underlying ...more »

Lipid and lipoprotein metabolism in the CNS

The analysis of lipoprotein metabolism has traditionally been restricted to the easily accessible circulation and peripheral tissues. Very little work has been done behind the blood brain barrier, where many of the lipid carrying or metabolizing genes are also expressed. Yet we know very little about their functions there, although for instance ApoE4 is THE primary risk factor for late-onset Alzheimer's disease. Conventional ...more »

Inflammation: what is the role of the blood microbiome?

Blood is not continuously sterile. Data from dental studies, blood donors, and random blood cultures document that "normal" human blood often harbors microbes. Sepsis only occurs when immunological regulatory systems fail. Growing evidence link subclinical, potentially transient bacteremia to cardiovascular and other diseases. Could many of the diseases associated with inflammatory markers represent either continuous ...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 »

In pulmonary arterial hypertension (PAH), how can right ventricular function be improved in the setting of increased afterload

Pulmonary arterial hypertension (PAH) is a complex, progressive condition characterized by high blood pressure in the lungs and restriction of flow through the pulmonary arterial system. Significant improvements have been made in medical management with through approved pulmonary vasodilator therapies. However, long-term right ventricular afterload reductions have still not yet been achieved. The process by which the ...more »

How can we increase the pharmaceutical clinical research of targeted therapies in pediatric PAH patients, including encouraging

Clinical research, especially randomized pharmaceutical clinical trials, poses many unique challenges compared to research in adult subjects. In pulmonary arterial hypertension, a disease characterized by high blood pressure of the lungs with increased pulmonary vascular resistance leading to right ventricular failure, there are 12 FDA-approved PAH-targeted therapies for adults. None of these medications are currently ...more »
