Nodular lymphocyte–predominant Hodgkin lymphoma (NLPHL) accounts for approximately 5% of all Hodgkin lymphoma cases. The aim of this study was to evaluate the prognostic implication of histopathologic NLPHL variants. Biopsies of 423 NLPHL patients treated within 9 prospective clinical trials perform

The factor VIII C2 domain is a highly immunogenic domain, whereby inhibitory antibodies develop following factor VIII replacement therapy for congenital hemophilia A patients. Inhibitory antibodies also arise spontaneously in cases of acquired hemophilia A. The structural basis for molecular recogni

Although monoclonal antibodies, including CD20 antibody rituximab, are standard therapeutics for several cancers, their efficacy remains variable and often modest. There is an urgent need to enhance the efficacy of the current generation of anticancer antibodies. Flt3 ligand, a soluble protein, has

Somatic gain-of-function mutations in interleukin 7 receptor α chain (IL7Rα) have been described in pediatric T and B acute lymphoblastic leukemias (T/B-ALLs). Most of these mutations are in-frame insertions in the extracellular juxtamembrane-transmembrane region. By using a similar mutant, a hetero

Hematopoietic stem cell transplantation (HSCT) is followed by a period of immune deficiency due to a paucity in T-cell reconstitution. Underlying causes are a severely dysfunctional thymus and an impaired production of thymus-seeding progenitors in the host. Here, we addressed whether in vitro–deriv

The c-Myc oncoprotein regulates >15% of the human transcriptome and a limited number of microRNAs (miRNAs). Here, we establish that in a human B-lymphoid cell line, Myc-repressed, but not Myc-stimulated, genes are significantly enriched for predicted binding sites of Myc-regulated miRNAs, primarily

The malignant Hodgkin and Reed-Sternberg (HRS) cells of Hodgkin lymphoma are surrounded by a tumor microenvironment that is composed of a variety of cell types, as well as noncellular components such as collagen. Although HRS cells harbor oncogenic Epstein-Barr virus (EBV) in approximately 50% of ca

Integrin αIIbβ3 plays a central role in hemostasis and thrombosis. We provide the first 3-dimensional reconstruction of intact purified αIIbβ3 in a nanodisc lipid bilayer. Unlike previous models, it shows that the ligand-binding head domain is on top, pointing away from the membrane. Moreover, unlik

Fludarabine plus cyclophosphamide (FC) is the chemotherapy backbone of modern chronic lymphocytic leukemia (CLL) treatment. CYP2B6 is a polymorphic cytochrome P450 isoform that converts cyclophosphamide to its active form. This study investigated the possible impact of genetic variation in CYP2B6 on

Smoldering multiple myeloma (SMM) bridges the gap between monoclonal gammopathy of undetermined significance (a mostly premalignant disorder) and active multiple myeloma (MM). Until recently, no interventional study in patients with SMM showed improved overall survival (OS) with therapy as compared

Superficial vein thrombosis (SVT) increases the risk of venous thrombosis fourfold to sixfold. As most individuals with SVT do not develop venous thrombosis, additional risk factors may explain the risk of developing a venous thrombosis. In the Multiple Environmental and Genetic Assessment of risk f

Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is an uncommon entity that, in contrast to classical Hodgkin lymphoma (cHL), universally expresses CD20, a hallmark of the disease. The majority of the patients present with early-stage disease, and treatment with local radiation provides excel

Although allogeneic hematopoietic stem cell transplantation (HSCT) remains the only curative treatment for patients with Fanconi anemia (FA), published series mostly refer to single-center experience with limited numbers of patients. We analyzed results in 795 patients with FA who underwent first HS

Kaposi sarcoma herpesvirus (KSHV)-associated multicentric Castleman disease (MCD) is a polyclonal B-cell lymphoproliferative disorder. Human (h) IL-6 and a KSHV-encoded homolog, viral IL-6, have been hypothesized to contribute to its pathogenesis, but their relative contributions to disease activity

TAL1 is an important regulator of hematopoiesis and its expression is tightly controlled despite complexities in its genomic organization. It is frequently misregulated in T-cell acute lymphoblastic leukemia (T-ALL), often due to deletions between TAL1 and the neighboring STIL gene. To better unders

Somatic heterozygous mutations of the DNA methyltransferase gene DNMT3A occur frequently in acute myeloid leukemia and other hematological malignancies, with the majority (~60%) of mutations affecting a single amino acid, Arg882 (R882), in the catalytic domain. Although the mutations impair DNMT3A c
