title: Progress and prospects: genetic engineering in xenotransplantation.
abstract: In this review, we summarize the work published over the last 2 years using genetic modifications of animals in the field of xenotransplantation. Genetic engineering of the donor has become a powerful tool in xenotransplantation, both for the inactivation of one particular porcine gene and for the addition of human genes with the goal of overcoming xenogeneic barriers. We summarize the work relative to the knockout of the alpha1,3-galactosyltransferase gene, followed by genetic engineering aimed at reducing the humoral and cellular immune response, complement activation and coagulation. Finally, we report on the genetic modification of pigs to reduce porcine endogenous retrovirus infection risk in the xenogeneic context.
