  Initial CHORUS data on HHT and ASH HematOmics Program 23.07.2026 26min

  In this week's episode, Blood editor Dr. James Griffin interviews Drs. Hanny Al-Samkari and Xin Zhou on their latest articles published in Blood. This episode highlights two important advances in hematology: the first report from the CHORUS registry for hereditary hemorrhagic telangiectasia (HHT) presented by Dr. Al-Samkari and also the introduction of the ASH Hematomics (ASHOP) platform for integrative genomic data analysis presented by Dr. Zhou. The CHORUS registry reveals that HHT is a progressive, underrecognized inherited bleeding disorder with a substantial burden of recurrent bleeding, iron deficiency, arteriovenous malformations, and life-threatening complications, while emphasizing the need for earlier diagnosis and the development of targeted therapies. The second presentation introduces ASHOP, an open-access platform that enables researchers to explore and integrate large-scale clinical and genomic datasets, facilitating discoveries in leukemia and other hematologic diseases through advanced analytical tools. Together, these studies demonstrate how comprehensive patient registries and innovative data-sharing resources are advancing precision medicine, improving disease understanding, and accelerating future research across hematology.

  IV Iron during Acute Infection and Revisiting iTTP Refractoriness 16.07.2026 16min

  In this week's episode, Blood editor Dr. James Griffin interviews Drs. Haris Sohail and Lucas Kühne on their latest articles published in volume 147 issue 21 of Blood. In this CME article titled, "Retrospective, Real-World Study of IV Iron Use to Treat Iron deficiency Anemia During Acute Infection",  Sohail et al show that IV iron given during acute infection with iron deficiency anemia is associated with improved 14-day and 90-day survival as well as hemoglobin recovery. Although this report has the limitations of a retrospective study, these findings challenge current practice and support randomized trials that include patients with infection. In "Revisiting Clinical Response and Refractoriness in Immune Thrombotic Thrombocytopenic Purpura", Kühne et al show in a multicenter registry study of 204 patients that refractoriness during caplacizumab treatment in immune TTP is uncommon and, when observed, is typically associated with confounding clinical factors. These findings underscore the importance of careful clinical reassessment and evaluation for alternative etiologies in patients with delayed platelet recovery, rather than attributing such cases to true treatment resistance.

  A Pediatric ITP Risk Model and Targeting CD2 with CAR T-cell therapies 09.07.2026 18min

  In this week's episode, Blood editor Dr. Laura Michaelis interviews Drs. Kirsty Hillier and Marco Ruella on their latest articles published in Blood. For "Predicting Development of Pediatric Chronic Immune Thrombocytopenia at Disease Onset Using a Statistical Risk Model", Dr. Hillier shares the potential benefits of incorporating this new model to enhance the care of the 1 in 4 patients who develop chronic ITP. As an alternative to current guidelines which advise providers to "wait and see", this online model determines patients who are at risk for chronic ITP, allowing for providers to make informed decisions on their continued care. In "Harnessing the CD2 axis to broaden and enhance the efficacy of CAR T-cell therapies", Dr. Ruella explains how the treatment of T-cell neoplasms is limited by a lack of discriminating T-cell antigens that allow for effective antitumor responses while preventing CAR T-cell fratricide. The team found that CD2 was a viable target, especially combined with a novel PD-1:CD2 switch receptor to remedy dysfunction caused by CD2 deletion.

  Orca-T for GVHD–free survival and Understanding VEXAS anemia 25.06.2026 23min

  In this week's episode, Blood editor Dr. Laurie Sehn interviews Drs. Everett Meyer and Olivier Hermine on their latest articles published in volume 147 issue 11 of Blood. Dr. Everett Meyer discusses "Orca-T vs allogeneic hematopoietic stem cell transplantation (PRECISION-T): a multicenter, randomized phase 3 trial" which demonstrated that Orca-T showed superior chronic GVHD–free survival compared to the control arm (78.0% vs 38.4%, P < .001) and lower nonrelapse mortality (3.4% vs 13.2%, P = .03). Dr. Olivier Hermine shares insights from "VEXAS anemia is a mosaic erythroblastopenia" which proposes that VEXAS syndrome–associated anemia should be considered as a mosaic erythroblastopenia, in which the severity of anemia is influenced by the quality and quantity of the UBA1–wild-type compartment.

  Effects of ZNF467 on HSPC fitness and Promotion of Follicular Lymphoma via DC-SIGN 30.04.2026 22min

  In this week's episode, Blood editor Dr. James Griffin interviews Drs. Francesco Forconi and Bin Guo on their latest articles published in Blood. Dr. Guo shares insights from "Nucleoplasmic ZNF467 condensates boost hematopoietic stem cell engraftment via ICAM1-mediated mechanical reprogramming". The findings establish biomechanical regulation as an important determinant of stem cell identity and reveal new strategies for engineering stem cells with enhanced regenerative capacity. Then, Dr. Forconi discusses "DC-SIGN binding to the surface immunoglobulin oligomannose-type glycans promotes follicular lymphoma cell adhesion and survival". Persistent, low-level BCR engagement by DC-SIGN enables FL tissue retention and survival while avoiding the deleterious proapoptotic consequences of stronger, conventional antigen-driven BCR signaling. These findings help explain how FL cells exploit their microenvironmental niche.

  Pathophysiology of ANKRD26-related thrombocytopenia and B-ALL recurrence after blinatumomab 23.04.2026 19min

  In this week's episode, Blood editor Dr. Laurie Sehn interviews Drs. Shengwen Calvin Li and Hrishi Krishna Srinagesh on their latest articles published in Blood. Dr. Li discusses "Single-cell profiling of ANKRD26 thrombocytopenia reveals progenitor expansion and polyploid apoptosis via JUNB-p21". The study identifies reproducible abnormalities in progenitor expansion and increased apoptosis of polyploid megakaryocytes, and they propose a novel mechanism in which centrosomal over-expression of ANKRD26 drives polyploid megakaryocyte apoptosis through JUNB-mediated induction of p21 transcription. Dr. Srinagesh discusses "Blinatumomab nonresponse correlates with poor survival after brexucabtagene autoleucel in B-cell ALL" in which data collected by the Real-World Outcomes Collaborative of CAR-T in Adult ALL consortium showed that prior nonresponse to blinatumomab was associated with inferior survival after brexucabtagene in comparison to blinatumomab-naïve patients. Early CAR-T responses were uniformly high regardless of prior exposure or response. This highlights that resistance to blinatumomab may identify patients at higher risk of post–CAR T relapse despite excellent initial responses.

  Emerging Mechanisms: Neutrophils and Immune thrombocytopenia from ICI 19.03.2026 19min

  In this week's episode of the Blood podcast, editor Dr. James Griffin interviews Drs. Christian Gorzelanny and Rebecca Leaf on their latest articles published in this week's issue of Blood. Dr. Gorzelanny discusses compelling evidence for a new mechanism that amplifies their proinflammatory actions in "Lipid nanotubes unmask neutrophils for complement attack", demonstrating the pathological role of this process in a range of inflammatory disorders in order to stimulate intense study of how to regulate nanotube formation for therapeutic benefit. In "Immune thrombocytopenia in patients treated with immune checkpoint inhibitors" Dr. Leaf and colleagues define the incidence, clinical features, and outcomes of ICI-induced immune thrombocytopenia. Showing that ICI-induced immune thrombocytopenia is associated with excess mortality, these data should provide an impetus to greater recognition and to protocolization of effective interventions.
