Scientists have discovered two new blood

Scientists from the University of Vermont in the U.S. have revolutionary discovery. As it turned out, in addition to well-known blood groups - I, II, III and IV - there are two new ones - and Junior Langerays.

Biologists believe that the discovery of these groups is a ...
According to research leader Brian Ballifa, the problem of incompatibility of blood types and Junior Langerays blood transfusion is a rare. However, certain ethnic groups are at greater risk.
... Japanese have a junior with a negative Rh factor and, therefore, may experience problems with blood transfusions, and the incompatibility of mother and fetus, ...
In collaboration with the French and Japanese counterparts professionals with mass spectrometry revealed two proteins on the surface of red blood cells - ABCB6 and ABCG2, which determine the blood group types of Langerays and Junior. These proteins belong to transport proteins ( involved in the transport of metabolites, ions inside the cell and out ).
... The last such discovery was made 10 years. Both of the identified proteins associated with resistance to anticancer drugs, so that research results can be used to improve the treatment of cancer (particularly breast cancer), ...
Next, the team conducted genetic tests confirming the connection of new proteins with the formation of blood systems Langerays and Junior.
In addition to the well-known ABO blood group system (the main blood group system, which is used for blood transfusions in humans) and Rh system, the International Society of Blood Transfusion has allocated 28 additional blood group - Duffy, Kidd, Diego, Lutheran and other. However Langerays and Junior has not yet been included in this list.
Despite the fact that the antigens for these blood groups have been identified 10 years ago, pregnant women having difficulty carrying a child with an incompatible blood type, genetic basis of these antigens was not known.
... However, the situation may soon change, ... This is especially important for patients being prepared for organ transplantation.
... Rejection may be associated with proteins ABCB6 and ABCG2, it also occurs when the immune system produces antibodies against the unknown blood, attacking your own body, ...
The scientist and colleagues continue to investigate the antigens on the surface of red blood cells. He believes that there are 10-15 of unknown blood group.
