Its immensely important to know the antigen make-up of your blood before undergoing blood transfusions, as mismatch can trigger a life-threatening immune response.

Taurine, a common ingredient in energy drinks, has been linked to leukemia cell growth. New research suggests targeting taurine uptake for leukemia treatment strategies.

The newly defined blood group, named the MAL blood group, follows this trend and is associated with a specific antigen known as AnWj, found in over 99.9 percent of the population.

A recent study showed the Kell antigen, which is associated with HDFN, is rare in a particular population descending from Nigeria. “Kell blood group is associated with haemolytic transfusion reactions ...

The clinical significance of Kell antibodies extends beyond transfusion medicine. Kell antigens, detectable on fetal red blood cells by the 10th week of gestation, can provoke severe HDFN. Maternal ...

Related: Blood types exist because red blood cells, which relay oxygen through the bloodstream, carry different proteins and sugars on their surfaces. These are called antigens.

The K antigen is one of the Kell blood group antigens that is generated early on in fetal development. In fact, because the K antigen is expressed in erythroid progenitor cells, which originate in the ...

Although this landmark paper officially adds a 47th blood group, there are still many unsolved antigens out there—hopefully they won’t take another 50 years to answer.

Scientists Discover New Blood Group, Solve 50-Year-Old Mystery This breakthrough solves a 50-year-old mystery surrounding the AnWj blood group antigen, first discovered in 1972.
