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 epside we'll learn about ADAMTS recovery after caplacizumab therapy in patients with immune thrombotic thrombocytopenic purpura. Then, we'll hear about preclinical characterization of sonrotoclax, a potential second-generation BCL2 inhibitor. Finally we'll hear about new insights into the etiology of Castleman disease where researchers describe the unusual occurrence of idiopathic multicentric Castleman disease in identical twins.  Featured Articles: ADAMTS13 recovery in acute thrombotic thrombocytopenic purpura after caplacizumab therapySonrotoclax overcomes BCL2 G101V mutation–induced venetoclax resistance in preclinical models of

In this week's episode, we’ll discuss the findings from a study assessing responses after treatment with tisagenlecleucel [LM1] in adults with relapsed/refractory follicular lymphoma, learn more about the association between high microRNA-145 plasma levels and decreased risk of future incident venous thromboembolism, and discuss how epigenetic and immunogenetic signatures can be used in the prediction of outcomes for high-count monoclonal B lymphocytosis.

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?  Featured Articles: CPX-351 exploits the gut microbiota to promote mucosal barrier function, colonization resistance, and immune homeostasisRegulatory T cells suppress myeloma-specific immunity during autologous stem cell mobilization and transplantationAntinuclear antibody–associated autoimmune cytopenia in childhood is a risk factor for systemic lupus erythematosus

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.
