New Enzyme Discovery Paves Way for Universal Donor Blood

Researchers have developed enzymes that convert type A and B blood into universal type O, potentially transforming blood transfusion practices.

Innovative enzymes from gut bacteria can strip A and B antigens from red blood cells, making them universally compatible.
The discovery by teams from Denmark and Sweden could drastically reduce blood supply shortages and improve emergency transfusion outcomes.
The enzymes, derived from the bacterium Akkermansia muciniphila, show high efficiency in transforming blood types under mild conditions.
Further research and clinical trials are needed to address remaining safety concerns and optimize the conversion process.
If successful, this technique could simplify blood logistics and reduce waste by eliminating the need to store multiple blood types.
