Background: B-cell chronic lymphocytic leukemia is the most frequent leukemia in the western world while T-cell large granular lymphocytic leukemia with cytotoxic (CD8+/CD3+CD4-) immunophenotype is rare. There is much ongoing interest regarding the interaction between T cells and B-cell chronic lymphocytic leukemia cells. Methods: Peripheral blood and bone marrow samples from a 72 year-old-man ...

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...

background: acute lymphoblastic leukemia (all) is the most common subtype of childhood cancer. chromosomal ab­normality, specially the replacement of chromosomal material is one of the main reasons in generating leukemia, wherein the kind of translocation play a key role in managing the remedy. the goal of the present study was to develop a reliable, rapid, and cost effective method to detect t...

T-cell acute lymphoblastic leukemia arises from the leukemic transformation of developing thymocytes and results from cooperative genetic lesions. Inactivation of the PHF6 gene is frequently observed in T-cell acute lymphoblastic leukemia, suggesting an important tumor suppressive role for PHF6 in the pathobiology of this leukemia. Although the precise function of PHF6 is still unknown, this ge...
