Blood Podcast

In this week’s podcast, we’ll look at research demonstrating that the histone acetyltransferase HBO1 is an essential regulator of hematopoietic stem cell function during adult hematopoiesis. Next, we’ll review a large, combined analysis confirming the prognostic value of MRD assessed with next-generation sequencing in 4 randomized trials evaluating daratumumab-based therapies. We’ll conclude with research demonstrating that ferroptosis, a specific type of regulated cell death, is a key mechanism of cardiomyopathy in sickle cell disease.

In this week’s podcast, we’ll discuss the role of megakaryocytic transcription factor ARID3A in leukemia suppression, learn more about the efficacy of a third Pfizer BNT162b2 mRNA COVID-19 vaccine dose in patients with chronic lymphocytic leukemia, and discuss the association of heterozygous caseinolytic peptidase B variants with congenital neutropenia.

On this week’s podcast, we’ll review a recent analysis of phase 3 daratumumab studies looking at the prognostic impact of sustained minimal residual disease, or MRD negativity in patients with multiple myeloma. Next, we’ll hear more about a novel thrombolytic agent targeting von Willebrand factor that may represent a promising approach for the treatment of thrombotic thrombocytopenic purpura. We’ll conclude with a study demonstrating that PI3 kinase inhibitor duvelisib can be used to enhance the in vivo efficacy of CAR T cells in CLL.

In this week’s podcast, we’ll discuss real-world outcomes comparing route of CNS prophylaxis for aggressive non-Hodgkin lymphomas, learn more about the association of clonal hematopoiesis with chronic obstructive pulmonary disease, and discuss the efficacy of all-trans retinoic acid plus low-dose rituximab in corticosteroid-resistant or relapsed immune thrombocytopenia.

On today’s podcast, we’ll explore the largest case series to date describing ALK-positive histiocytosis. The authors provide new insights on the disease and its treatment with ALK inhibitors, which can provide durable responses. We’ll also review with a study that pinpoints alpha-ketoglutaric acid as consistently elevated in pediatric chronic GvHD, and finds unique metabolomic patterns that appear to distinguish different GvHD subtypes.

In this week’s podcast, we’ll talk about the long-term outcomes in patients with severe aplastic anemia treated with immunosuppression and eltrombopag, learn more about anti-inflammatory and cytoprotective effects of factor VIIa, and discuss the role of IL-1 in microbiome-induced ageing of hematopoietic stem cells in mice.

In this week’s episode, we’ll review a research article that provides the first description of a targeted gene insertion approach to correct the genetic mutation underlying XMEN disease. Next, we’ll cover results of a phase 2 study that provides proof-of-principle that the JAK/STAT pathway is a promising target for the treatment of peripheral T-cell lymphomas. We’ll close with a study providing precise and up-to-date estimates on the incidence of intracranial hemorrhage in patients with hemophilia that could have important implications for preventive strategies.

In this week’s episode, we’ll review a research article demonstrating that some platelet-derived extracellular vesicles harbor proteasomes that can process and present antigens via MHC class I molecules. Next, we’ll review results of a phase 1 study of a fibril-reactive monoclonal antibody that was well tolerated and led to rapid, sustained organ responses in patients with AL amyloidosis. We’ll close with a research article suggesting that the pore-forming protein gasdermin D, which plays a crucial role in the release of neutrophil extracellular traps, is a promising drug target in sepsis.

In this week’s episode, we’ll talk about the functional properties of mesenchymal stromal cells in sickle cell disease, learn more about CAR T-cell-mediated hematotoxicity in relapsed/refractory B-cell lymphoma, and discuss dual cytokine blockade in graft-versus-host disease.

In this week’s episode, we’ll learn about a new approach for targeting Janus kinases in CRLF2-rearranged ALL, discuss risk stratification for myeloid leukemia in children with Down syndrome and learn more about how sialic acid alterations on megakaryocyte antigens regulate immune cells and platelet production.
