A team of researchers claims to have found a way to manipulate the enzymes present in blood supplies, potentially bringing them a step closer to creating a type of blood that could be given to virtually any patient. And that could have significant societal consequences. Global blood supplies are in short supply, particularly in low-income […]
Researchers have identified enzymes in gut microorganisms that could cleave A and B antigens from red blood, transmuting them to O negative cells. This is “a decisive step forward” in the quest to develop a universal donor blood that can be administered to people of any blood group without eliciting a harmful immune response, according to Maher Abou Hachem of the Technical University of Denmark, who co-led the research.
