XENOTRANSPLANT
UAB researchers establish optimal immunosuppression regimen for pig-to-human kidney transplants
The regimen — which includes already FDA-approved medications, plus the use of a complement inhibitor — showed remarkable success in Parsons model case series.
Xenotransplant is defined as transplanting an animal organ or product into a human to cure disease. Utilizing genetically modified pig kidneys could provide an increased supply for those needing a kidney transplant.
Why do we need xenotransplantation?
“We have this amazing therapy called kidney transplantation that works 95 to 98 percent of the time, and yet there are only about 25,000 kidneys to go around in the U.S. every year, but we have 800,000 people who need them. The hardest part is seeing patients in clinic and wait-listing them knowing they might actually die before I ever get an organ-offer to transplant them.
So the opportunity to have an organ that is waiting there for the person who needs it is just overwhelming to think about. I feel very privileged to be just a tiny part of a really big puzzle that people have been working on for many years.”
