In this week’s episode, we’ll review results of a phase 2 study showing the beneficial effects of a first-in-class factor D inhibitor as add-on therapy in PNH patients who remain anemic and are transfusion-dependent despite C5 inhibition. Next, we’ll review the work of researchers who have developed a neural network that they say is highly accurate in differentiating between bone marrow cell morphologies. We’ll close with a report demonstrating that RNA editing of antizyme inhibitor 1, or Azin1, is a novel regulator of hematopoietic cell fate that can influence self-renewal and differentiation.
