The shortage of human organs for transplantation has driven significant advancements in xenotransplantation, particularly using genetically modified pigs. This study examines the genetic modifications in pigs aimed at reducing immune rejection in human recipients. Recent studies have demonstrated the potential of porcine organs with multiple genetic modifications to overcome hyperacute rejection and improve graft survival. Key genetic alterations include the knockout of xenoantigens such as alpha-1,3-galactosyltransferase and the insertion of human complement and coagulation regulatory genes. These modifications have shown promising results in preclinical and early clinical trials, with some xenografts maintaining function without signs of rejection for extended periods. The study highlights the importance of continued research to optimize genetic modifications and address remaining immunological and physiological barriers to clinical xenotransplantation.
