Goal 2: Reduce Human Disease

Mitigating risks due to the RBC storage lesion and vulnerable patients

What are the underlying dependencies (genomic, metabolic, disease) in individual donors that either accelerate or delay the changes to red blood cells during refrigerated storage? What methods of preparation might protect patients from the risks posed by the accelerated degradation of RBCs provided by "poor storers"? What characteristics of individual patients make them particularly vulnerable to transfusion of red... more »

Goal 3: Advance Translational Research

Stem Cell Biology

There is a need to develop “designer platelets” and “designer red cells,” as well as facilitate large-scale production of these products for therapeutic and diagnostic use.

Goal 2: Reduce Human Disease

Anemia, oxygen delivery, and red blood cell transfusion

In neonatal, pediatric, and adult patients with critical illness, what is the best means to identify: (1) the degree to which anemia contributes to insufficient oxygen (O2) delivery and (2) the likelihood that O2 delivery will be improved by red blood cell (RBC) transfusion? These questions are most relevant to critically ill populations that exhibit unique physiology, including those with low cardiac output (cardiac... more »

Goal 2: Reduce Human Disease

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 2: Reduce Human Disease

The potency and safety of transfusable red blood cells

Can we identify approaches to improve potency and/or safety of transfusable RBCs? 42 day pre-transfusion storage of RBCs maximizes utilization, while minimizing waste. However, RBCs undergo changes during collection, manipulation and storage that may reduce their potency or safety. Progress in understanding markers that predict transfusion success at the time of collection and with storage remains slow. New technologies... more »

Goal 2: Reduce Human Disease

Apheresis Medicine in the Management of Sickle Cell Disease

Despite advances in care, patients with sickle cell disease have significant morbidity and mortality. One challenge is the optimal use of simple vs exchange transfusion vs no transfusion when managing these patients. Simple transfusions lead to iron overload while exchange transfusions may expose patients to increase numbers of red blood cell units. The mechanism of benefit from transfusion (oxygen delivery vs marrow... more »
