Molecular mimicry in aplastic anemia; emicizumab prophylaxis in infants with hemophilia; hydroxyurea reduces infections in SCA

In this week's episode we'll discuss molecular mimicry in aplastic anemia, novel experiments show that antigens associated with viral infections can mimic epitopes presented on hematopoietic progenitor cells. Then, we'll learn about prophylaxis with subcutaneous emicizumab in infants with hemophilia. Finally we'll see how hydroxyurea is associated with a significant reduction in infections among children with sickle cell anemia in Uganda.

Articles featured this week:

• Virus-reactive T cells expanded in aplastic anemia eliminate hematopoietic progenitor cells by molecular

• Emicizumab prophylaxis in infants with hemophilia A (HAVEN 7): primary analysis of a phase 3b open-label
  trial
