Scientists bioengineer a protein to fight leukemia

Scientists at the Children's Center for Cancer and Blood Diseases and The Saban Research Institute of Children's Hospital Los Angeles today announced a breakthrough discovery in understanding how the body fights leukemia. They have identified a protein called CD19-ligand (CD19-L) located on the surface of certain white blood cells that facilitates the recognition and destruction of leukemia cells by the immune system. This work represents the first report of a bioengineered version of CD19-L, a recombinant human biotherapeutic agent, targeting CD19-positive leukemic stem cells.
