Megakaryocytes contribute to multiple processes in the body, including platelet production and regulation of hematopoietic stem cells. Therefore, it is not surprising that alterations in this lineage not only affect platelets but also impact hematopoiesis in other ways. Fortunately, our understanding of megakaryocyte biology has increased significantly with the advent of advanced technologies such as next-generation sequencing and sophisticated microscopy.

In this week's podcast we'll discuss another step forward in stamping out high-risk myeloma. Then we'll hear about the plasmin-cleaved von Willebrand factor, or VWF, in microthrombosis. Finally we'll hear about new insights into the origins of sickle cell pain.  Featured Articles:Daratumumab, carfilzomib, lenalidomide, and dexamethasone with tandem transplant for high-risk newly
diagnosed myelomaPlasmin-cleaved von Willebrand factor as a biomarker for microvascular thrombosisSickle cell disease iPSC-derived sensory neurons exhibit increased excitability and sensitization to patient

In this week's episode we’ll discuss the utility of MRD in identifying patients with NPM1 AML who benefit from allogeneic transplant in first remission, learn more about the contribution of circulating hematopoietic stem/progenitor cell subsets to human hematopoietic hemostasis, and discuss the role of Let-7 miRNAs in regulation of BCL11A transcription and hemoglobin switching.  Featured Articles:Postinduction molecular MRD identifies patients with NPM1 AML who benefit from allogeneic transplant in first remissionlet-7 miRNAs repress HIC2 to regulate BCL11A transcription and hemoglobin switching Circulating Hematopoietic Stem/Progenitor Cell subsets contribute to human hematopoietic homeostasis

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

ADAMTS13 recovery in caplacizumab-treated TTP; inhibition of venetoclax-resistant BCL2 variants with sonrotoclax; genomic insights from Castleman disease in twins

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
