An international team of researchers have identified two new blood types, named Langereis and Junior, which have implications for improvements in blood transfusions and organ transplants. These two new blood groups can be added to the list of internationally recognized blood types, which currently has 28 members in addition to the well-known ABO and Rhesus blood types. The scientists were able to identify the proteins that form the molecular basis of Langereis and Junior. These proteins, ABCB6 and ABCG2, function as transporters on red blood cells and have also been linked to anti-cancer drug resistance.
