We determined the prevalence and significance of finding B cells without surface immunoglobulin (SIg) light chain expression. The flow cytometry database at Johns Hopkins Medical Institutions was searched for cases in which immunoglobulin light chain staining was performed to rule out a B-cell malignant neoplasm between January 1994 and February 2000. We excluded plasma cell dyscrasias, precurs...
SUMMARY By comparing the genomes of progenitor cells and mature cells of lymphoid and myeloid lineages in patients with chronic lymphocytic leukemia (CLL), Damm and colleagues confirmed that CLL originates from preleukemic CD34(+) progenitor cells and identified early CLL mutations that are associated with these progenitor cells. Moreover, they discovered that deregulation of B-cell receptor si...
Iron Metabolism & Its Disorders Pathways for the regulation of hepcidin expression in anemia of chronic disease and iron deficiency anemia in vivo Igor Theurl, Andrea Schroll, Manfred Nairz, Markus Seifert, Milan Theurl, Thomas Sonnweber, Hasan Kulaksiz, and Guenter Weiss Leukemogenesis MLL-ENL leukemia burden initiated in femoral diaphysis and preceded by mature B-cell depletion Agnieszka Jara...
Purpose: Chronic lymphocytic leukemia (CLL), a malignancy of mature B cells, is incurable with chemotherapy. Signals from the microenvironment support leukemic cell survival and proliferation and may confer chemotherapy resistance. ON 01910.Na (Rigosertib), a multikinase phosphoinositide 3-kinase (PI3K) inhibitor, is entering phase III trials for myelodysplastic syndrome. Our aim was to analyze...
Abstract CD4 T cell exhaustion is associated with relapse in B leukemia (B-ALL) patients. However, checkpoint blockade not effective treating B-ALL. Using a murine model of B-ALL, we demonstrate that induced cells had unique regulatory-cytotoxic phenotype (T rctx) preferential expression markers (PD1/TIM3) as well IL10 and c-Maf, which are immunosuppressive Tr1 cells. Leukemia acting APCs elici...
Chronic lymphocytic leukemia is a malignancy of mature B cells that strongly depend on microenvironmental factors, and their deprivation has been identified as a promising treatment approach for this incurable disease. Cytokine array screening of 247 chronic lymphocytic leukemia serum samples revealed elevated levels of tumor necrosis factor (TNF) receptor-1 which were associated with poor clin...
We report the establishment of a leukemia cell line (UoC-B10) from a patient who developed leukemia several months after the diagnosis of a mediastinal yolk sac tumor. The patient's yolk sac tumor responded to combination chemotherapy, and a mature teratoma with focal areas of hematopoiesis was subsequently resected. However, 5 months after the initial diagnosis, the patient developed an acute ...
To clarify the nature of null cell acute lymphoblastic leukemia (ALL) we tested null lymphoblasts and other leukemic cells for human T and B lymphocyte antigens detected by reciprocally absorbed rabbit antisera prepared against autologous T and B lymphoblast cell lines HSB-2 and SB. Blasts from 4 of 4 patients with T cell leukemia and from 2 of 10 patients with null cell leukemia expressed T ce...
