Hairy cell leukemia is a chronic B-cell lymphoid leukemia characterized by pancytopenia, splenomegaly, myelofibrosis and the presence in peripheral blood, bone marrow and spleen of atypical lymphoid cells with a hairy aspect and a particular immunophenotypic profil. The association HCL and tuberculosis has been established, but only few cases have been reported. We report a case of bone marrow ...

Interferons (IFNs) initiate their effects by interacting with specific high-affinity cell surface receptors, but little is known about the physiology of IFN receptor interaction in vivo. Treatment of patients suffering from hairy cell leukemia (HCL) with human recombinant alpha IFN results in significant tumor regression, with clinical improvement in a high percentage of cases. To investigate a...

BACKGROUND Hairy cell leukemia (HCL) is a chronic B-cell lymphoid leukemia characterized by pancytopenia, splenomegaly, myelofibrosis and the presence in peripheral blood, bone marrow and spleen of atypical lymphoid cells with a hairy aspect. The study aims to evaluate a group of patients with hairy cell leukemia, hospitalized in the Clinic of Hematology and Oncology, Kermanshah, Iran, on a per...

The phenotype of fresh and cultured leukemic cells from patients with hairy cell leukemia was studied using a panel of monoclonal antibodies in addition to the detection of peroxidase activity under electron microscopy. In fresh samples, the leukemic cells from 11 patients displayed predominantly a B phenotype, as judged by their reactivity with the B1 monoclonal antibody and surface immunoglob...

In this issue of Blood, Pettirossi et al, including Drs Tiacci and Falini, who led the effort in 2011 defining the BRAF-V600E driving mutation in hairy cell leukemia (HCL),provide extensive laboratory studies showing that inhibitors of BRAF-V600E and/or mitogen-activated protein kinase kinase (MEK) reach their targets and cause HCL cell death

BACKGROUND Rare diseases present challenges for patients, healthcare providers, and researchers. Rare disease communities exist for collaboration, dissemination of information, and to promote support for all community members. Patients with a rare disease desire to be supported through a rare disease community. Hairy cell leukemia (HCL) is a rare adult B-cell lymphocytic cancer that currently h...

Purpose: To determine tolerability and for the first time explore efficacy of bendamustine–rituximab (BR) in multiply relapsed/refractory hairy cell leukemia (HCL), using two different dose levels of

The spatial organization of Drosophila melanogaster epidermal structures in embryos and adults constitutes a classic model system for understanding how the two dimensional arrangement of particular cell types is generated. For example, the legs of the Drosophila melanogaster adult are covered with bristles, which in most segments are arranged in longitudinal rows. Here we elucidate the key role...

Seeds of Silybum marianum which have been used to treat liver diseases have an active component called silymarin. Hairy root cultures of S. marianum could be able to produce silymarin. There is evidence that the use of elicitors has been an important strategy for improving the production of secondary metabolites. Elicitation is an interesting topic to investigate cell signaling pathway in secon...
