IL-6 is a cytokine that is involved in various physiological and pathological conditions, and approaches using gain-of-function transgenic animals have contributed in elucidating IL-6 function. However, studies of the multiple functions of IL-6 in vivo are very time consuming because they require the generation of transgenic mice that harbor the gene encoding IL-6 under the control of specific ...
Abstract Introduction/Objective T-cell large granular lymphocytic leukemia (T-LGL) is a lymphoma with persistently increased lymphocytes in peripheral blood. The majority of T-LGL associated CD8+ T-cells. However, the CD4+ variant uncommonly seen. Methods/Case Report patient 49-year-old female history diabetes mellites and anemia who presented shortness breath, lower extremities edema, fatigue....
Aggressive natural killer cell leukemia (ANKL) is an extremely rare type of leukemia characterized by clonal NK cell infiltration of peripheral blood and the bone marrow, cytopenias, and hepato/splenomegaly. ANKL is an aggressive subtype of a large granular lymphocytic (LGL) leukemia. Peripheral blood smear shows LGL cells containing characteristic azurophilic granules in a light pale basophili...
The initial characterization of two monoclonal antibodies directed at antigens selectively expressed on large granular lymphocytes (LGL) is reported in the present paper. These two reagents, anti-natural killer (NK) H1A and anti-NKH2, were obtained following immunization of mouse spleen cells with a cloned human NK cell line termed JT3. In fresh human peripheral blood, both anti-NKH1A and anti-...
A major focus at the Large Hadron Collider (LHC) will be Higgs boson studies and it would be an interesting prospect to simultaneously probe for physics beyond the Standard Model (SM) in the Higgs signals. In this work we show as to what extent, the effects of Universal Extra Dimension (UED) can be isolated at the LHC through the Higgs signals. By doing a detailed study of the different uncerta...
Large granular lymphocyte (LGL) leukemia, or LGLL, is characterized by increased numbers of circulating clonal LGL cells in association with neutropenia, anemia, rheumatoid arthritis, and pulmonary artery hypertension (PAH). Emerging evidence suggests that LGLL cells with a CD8(+)CD28(null) phenotype induce these clinical manifestations through direct destruction of normal tissue. Compared with...
The expression of interleukin 2 receptor (IL-2R) on leukemic cells of natural killer (NK) and T cell lineages in two patients with large granular lymphocytic (LGL) leukemia was examined. The p55 Tac IL-2R was not detected by the indirect immunofluorescence method and it did not participate in the IL-2 binding to the surface of these cells. However, these leukemic cells proliferated in a IL-2 do...
The natural killer (NK) type of aggressive large granular lymphocytic (LGL) leukemia is a fatal illness that pursues a rapid clinical course. There are no effective therapies for this illness, and pathogenetic mechanisms remain undefined. Here we report that the survivin was highly expressed in both aggressive and chronic leukemic NK cells but not in normal NK cells. In vitro treatment of human...
We presented a 64-year-old male patient with T-large granular cell leukemia/lymphoma with an agressive clinical course. Large granular lymphocytes were noted on peripheral blood smear. The phenotyping of the cells was typical T-cell lineage [CD2 (+), CD3 (+), CD5 (+)]. Clonal rearrangement of the T-cell receptor gene (TCR) was demonstrated by DNA hybridization technique. Large granular cell leu...
Serologic studies in a male Caucasian presenting with an acute hepatitis-like illness, associated with an increase in peripheral blood large granular lymphocytes (LGLs), suggested a chronic or reactived Epstein-Barr virus (EBV) infection. The LGL were shown to have a natural killer (NK) cell, CD3- CD16- CD56+ CD57- phenotype and mediated strong nonspecific major histocompatability complex-unres...
