Blood Podcast

This week’s episode covers recent research that provides new insights in erythropoiesis, mastocytosis, and chronic active EBV. First, we’ll review a report describing how interactions between an E3 ubiquitin ligase and a heterochromatin-associated protein may serve as a “toggle” of sorts to regulate the formation of red blood cells. Next, researchers find that presence of hereditary α tryptasemia may predict the risk of severe anaphylaxis in patients with mastocytosis. Finally, we’ll review a report revealing large numbers of myeloid-derived suppressor cells in patients with EBV-associated T/NK cell lymphoproliferative disorders, which may have important implications for understanding disease pathogenesis and targeted approaches to therapy.

In this week’s episode, we will review a study that shows that non-invasive imaging of T cell metabolic activity can detect early graft-versus-host disease after allogeneic hematopoietic stem cell transplantation, learn more about how detailed assessment of measurable residual disease in multiple myeloma can better define outcomes and how treatment resistance arises, and finally, examine the mechanism of action and pharmacokinetics of Ciraparantag, a small molecule being developed to rapidly reverse the effects of anticoagulants.

In this week’s episode, we will review a study that evaluates the role of pre-transplant leukocyte telomere length on survival outcomes in patients with myelodysplastic syndrome, learn more about a potential novel treatment for patients with WHIM syndrome, and examine a novel mechanism important for the maintenance of normal hematopoietic stem cell quiescence, and hence, long-term blood formation.

In this week’s episode, we will learn more about T-cells from SARS-CoV-2-infected individuals, review a study that describes the rapid clinical and histologic response to anti-PD1 first-line therapy in early-stage, unfavorable Hodgkin lymphoma, and discuss a meta-analysis and systematic review of outcomes of patients with hematologic malignancies and Covid-19.

In this week’s episode, we will review a study describing real-world data where PET scans following chemotherapy for primary mediastinal B-cell lymphoma were used to guide consolidative radiotherapy, learn more about the novel role of the BLOC-2 protein complex in the formation of Weibel-Palade bodies that store von Willebrand Factor in endothelial cells, and finally, examine how mutant TP53 in myelodysplastic syndrome is associated with immune checkpoint overexpression in the bone marrow.

In this week’s episode, we will review a study that describes how transfer of whole mitochondria from hematopoietic stem cells to bone marrow mesenchymal stem cells helps regenerate the stroma and its capacity to sustain hematopoietic recovery in irradiated mice undergoing stem cell transplant, examine the potential benefit of adding the BCL2-inhibitor, venetoclax, to standard treatment regimens for patients with relapsed or refractory follicular lymphoma, and finally, we will learn more about how NCOA4, the autophagic receptor for ferritin, is necessary for the mobilization of liver iron stores during stress erythropoiesis.

In this week’s episode, we will review a study that reveals a previously unknown role for the canonical Wnt signaling pathway in the regulation of granulocyte production in steady state and emergency granulopoiesis, examine the discordance in different assays that measure factor VIII activity after adenoviral-associated gene therapy, and learn about the dynamics of declining antibody levels in repeat Covid-19 convalescent plasma donors.

In this week’s episode, we will review an proof-of concept study using the bispecific antibody AFM13 in combination with a check-point inhibitor in patients with relapsed or refractory Hodgkin lymphoma, learn more about how iron restriction might be a promising new therapy for congenital erythropoietic porphyria, and review a manuscript that provides novel molecular insights into the requirement for RUNX1 in a mouse model of inversion 16 acute myeloid leukemia, providing a path forward for new therapies to treat this subgroup of AML.

In this week’s episode, we will review a study on the involvement of lysine-specific, we’ll cover some of the latest findings in COVID-19, multiple myeloma, and myelodysplastic syndromes. First, we’ll review an observational, multicenter study suggesting that convalescent plasma with anti-SARS-CoVid-2 antibodies may be a promising therapy in B-cell depleted patients who have prolonged COVID-19 symptoms. Next, we’ll discuss a research article showing that inhibition of JAK-STAT3 signaling with ruxolitinib could upregulate CD38 expression, thereby enhancing daratumumab-mediated cytotoxicity in multiple myeloma. Finally, we’ll review a report showing for the first time that in MDS, machine learning algorithms can be used to reveal novel associations between morphologic features and genetic lesions that may have important prognostic implications.

In this week’s episode, we will review a study on the involvement of lysine-specific demethylase 1A in hematopoietic stem cell expansion, examine the role of platelet receptor PAR4 in venous thromboembolism; and finally, investigate the relative contributions of maternal versus fetal hepcidin in embryonic iron endowment in both healthy and inflammatory states.
