In this week's episode, we’ll learn more about social determinants of health that impact access to allogeneic hematopoietic cell transplantation in patients with acute myeloid leukemia, or AML; use of megakaryocyte growth factor receptor-based stem cell depletion as part of pretransplant conditioning in ex vivo autologous gene therapy; and identification of an eight-protein risk signature as well as a novel single protein biomarker, soluble oncostatin M receptor, for risk stratification in AML.

Blood editor Dr. Laurie Sehn discusses the topic of "Aggressive non-Hodgkin lymphoma: defining and managing high-risk subsets" featuring Drs. Mark Roschewski, Grzegorz Nowakowski, and Neha Mehta-Shah, who each contributed to the articles featured in the review series on high-risk aggressive lymphoma.

In this week's episode, we' ll learn about how TET3 has a key role in GVHD. In mice, a deficiency of Tet3 in donor T cells inhibited pathogenic immunoglobulin class switching and suppressed lung fibrosis. Accordingly, TET3 may be a new therapeutic target in chronic GVHD. After that: rilzabrutinib, a BTK inhibitor for ITP. In a randomized, placebo-controlled trial, treatment produced rapid and durable platelet responses, with acceptable safety, in adults with immune thrombocytopenia who had failed multiple previous therapies. Finally: exploring pre-TCR surface expression patterns in T-cell ALL. Co-inhibition of the interleukin-7 receptor and pre-T cell receptor pathways may play a therapeutic role for a subset of T-lymphoblastic leukemias.
