A type A kidney was successfully converted to type O using enzyme therapy and transplanted into a brain-dead patient, avoiding rejection.
A kidney from a blood type A donor was successfully converted to type O using enzyme technology developed at the University of British Columbia and transplanted into a brain-dead recipient, marking the first human trial of its kind.
The converted kidney functioned normally for two days without hyperacute rejection, with only mild immune response observed by day three.
The enzyme treatment removed type-A antigens that trigger rejection, potentially enabling organs to be used across blood types.
The procedure, over a decade in development, could expand the donor pool and reduce transplant wait times.
Regulatory approval for clinical trials is next, with UBC spin-off Avivo Biomedical leading the effort.
