Collection of Blood in Normal Subjects and Subjects With Von Willebrand Disease (VWD)

2014-08-27 03:32:24 | BioPortfolio


Von Willebrand disease is an inherited bleeding disorder that impacts the blood's ability to clot properly. Von Willebrand disease is cause by the lack or not working substance in the blood known as Von Willebrand factor.

Current therapy for Von Willebrand disease includes desmopressin acetate (DDAVP) and /or VWF/FVIII concentrates. Patients with severe Von Willebrand disease face a lifetime of weekly treatments and mounting medical bills. Gene therapy could help these patients improve their quality of life by providing the missing factors necessary for the blood's ability to clot properly.

The gene transfer options being studied include naked DNA, viral gene transfer vectors encoding Von Willebrand factor transgenes, and ex vivo cell therapy. The latter involves transplantation of the patient's own cells modified with a corrected copy of the defective gene. Human blood outgrowth endothelial cells (BOEC) display all the properties needed for successful ex vivo cell therapy. We plan to obtain blood samples from normal research subjects and patients with Von Willebrand Disease in order to isolate blood outgrowth endothelial cells (BOEC) from peripheral blood, and develop a ex vivo gene therapy for Von Willebrand Disease.

Medical and Biotech [MESH] Definitions

A subtype of von Willebrand disease that results from a partial deficiency of VON WILLEBRAND FACTOR.

A subtype of von Willebrand disease that results from qualitative deficiencies of VON WILLEBRAND FACTOR. The subtype is divided into several variants with each variant having a distinctive pattern of PLATELET-interaction.

A subtype of von Willebrand disease that results from a total or near total deficiency of VON WILLEBRAND FACTOR.

A high-molecular-weight plasma protein, produced by endothelial cells and megakaryocytes, that is part of the factor VIII/von Willebrand factor complex. The von Willebrand factor has receptors for collagen, platelets, and ristocetin activity as well as the immunologically distinct antigenic determinants. It functions in adhesion of platelets to collagen and hemostatic plug formation. The prolonged bleeding time in VON WILLEBRAND DISEASES is due to the deficiency of this factor.

Group of hemorrhagic disorders in which the VON WILLEBRAND FACTOR is either quantitatively or qualitatively abnormal. They are usually inherited as an autosomal dominant trait though rare kindreds are autosomal recessive. Symptoms vary depending on severity and disease type but may include prolonged bleeding time, deficiency of factor VIII, and impaired platelet adhesion.
