Effect of cell surface concentration of human DAF on transgenic pig aortic endothelial cells on the degree of protection afforded against human complement deposition.

abstract：:Xenotransplantion remains the most viable option for significant expansion of the donor organ pool in clinical transplantation. With the advent of nuclear transfer technologies, the production of transgenic swine has become a possibility. These animals have allowed transplant investigators to overcome humoral mechanis...

abstract：:Previous data suggest that natural anti-Galalpha1,3Gal (Gal) antibody (Ab) is produced by mature plasma cells. As thalidomide is effectively used in the treatment of patients with multiple myeloma, its effect on natural anti-Gal Ab production has been assessed in two baboons. During a 10-week course of thalidomide adm...
