Previous studies have demonstrated that the T cell costimulatory molecule, CD28, is important in the development of humoral immunity. CD28-deficient mice exhibit defects in isotype switching and are more susceptible to pathogens that depend on an effective Ab response. To determine the basis of these defects, we have examined B cell responses of(More)
Hematopoietic cell transplantation (HCT) is performed in select centers in the United States (U.S.), and patients are often required to temporarily relocate to receive care. The purpose of this study was to identify housing barriers impacting access to HCT and potential solutions. A mixed-methods primary study of HCT social workers was conducted to learn(More)
Hematopoietic cell transplantation (HCT) is the only known curative therapy for many patients with life-threatening hematologic and oncologic diseases. It is estimated that the National Marrow Donor Program(®) (NMDP) will facilitate 10,000 transplants by 2015, double the current number. To better understand the existing personnel and center infrastructure(More)
Although hematopoietic cell transplantation (HCT) is an effective treatment option for patients with life-threatening blood, immune system, or genetic disorders, many barriers besides a lack of suitably matched donors exist and can have an adverse impact on access and outcomes of HCT. In 2008, the National Marrow Donor Program, through its Office of Patient(More)
The recombinase-activating genes, RAG-1 and RAG-2, have been shown to be necessary to initiate the process of V(D)J recombination during the ontogeny of lymphocytes. While much is known about the end products of this rearrangement process, little is known about the function or regulation of the components of the recombinase system. To this end, we have(More)
Gene-targeted livestock can be created by combining ex vivo manipulation of cultured nuclear donor cells with cloning by nuclear transfer. However, this process can be limited by the low gene targeting frequencies obtained by transfection methods, and the limited ex vivo life span of the normal nuclear donor cells. We have developed an alternative gene(More)
African Americans and Blacks have low participation rates in clinical trials and reduced access to aggressive medical therapies. Hematopoietic cell transplantation (HCT) is a high-risk but potentially curative therapy for sickle cell disease (SCD), a disorder predominantly seen in African Americans. We conducted focus groups to better understand(More)
Vertebrates are able to mount specific immune responses because they possess a vast array of antigen-specific B and T cells. In B cells, the antigen receptor is a membranebound form of immunoglobulin, whereas in T cells the antigen-specific component of the T cell receptor (TCR) is composed of a heterodimer of either TCR c1 and j3 gene products or TCR y and(More)
