Blood Podcast American Society of Hematology

In this week's episode, we'll discuss gut microbiota exploitation by CPX-351 in acute myeloid leukemia. Then we'll learn about optimizing anti-myeloma immunity. New research shows that regulatory T cells suppress myeloma-specific immunity during autologous stem cell mobilization and transplantation. Finally we'll discuss among pediatric patients with ITP or other autoimmune cytopenias, which ones will go on to develop systemic lupus?

In this week's episode we’ll discuss the mechanism by which Jak2V617F clonal hematopoiesis promotes arterial thrombosis, discuss how Staphylococcus aureus induces drug resistance in cancer T cells in Sézary syndrome, and learn more about the clinical and functional features of RAC2-related immunodeficiency.

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.

In this bonus episode of Blood Podcast, Associate Editor, Dr. Freda Stevenson is joined by Drs. Karin Tarte, Andrea Radtke, and Leandro Cerchietti to discuss the Review Series on the influence of the tumor microenvironment on the pathogenesis of B-cell lymphomas.
Find the full review series in Blood Journal volume 143 issue 12. 

In this week's episode we’ll discuss the findings from a study assessing the utility of free light chain mass spectrometry in AL amyloidosis, learn more about distinct single-cell RNA-sequencing signatures of bone marrow T cells of AML patients in remission after an allogeneic stem cell transplant, and discuss why von Willebrand factor clearance is critical for the protective effect of ADAMTS13 in mice with sickle cell anemia.

In this week's episode we'll discuss eculizumab in stem cell transplant-associated thrombotic microangiopathy. Then, we'll learn about reclassifying malignant monocytosis, these newly classified cases have distinct mutational and transcriptional profiles. Finally, we'll hear about targeting the tissue factor coagulation initiation complex prevents antiphospholipid antibody development.
