Mice deficient in the interferon consensus sequence binding protein (ICSBP) develop a disease resembling chronic myeloid leukemia (CML), which in humans is caused by the BCR/ABL oncoprotein. Interferon-alpha (IFN-alpha) induces ICSBP expression and is an effective therapy for CML. This study examined whether enforced expression of ICSBP might antagonize BCR/ABL-induced leukemia; results demonst...

Cytokines affecting mononuclear phagocytes were screened for activation of human macrophages to secrete H2O2 and kill toxoplasmas. In contrast to recombinant interferon-gamma (rIFN gamma), the following factors, tested in partially or highly purified form and over a wide range of concentrations, did not augment these functions: native interferon-alpha (nIFN alpha), rIFN alpha A, rIFN alpha D, r...

The manner by which the trans-acting factor encoded by the 1,828-base-pair (bp) BamHI DNA fragment of hepatitis B virus (HBV) suppresses the production of human beta interferon was determined. Steady-state levels of RNA specific for human beta interferon were decreased in cells that contained the 1,828-bp BamHI DNA fragment of HBV. The reduced accumulation of interferon-specific RNA was due to ...

Levels of macrophage colony-stimulating factor (nine of nine patients) and gamma interferon (six of nine patients) in serum were elevated above the range of normal in the acute phase of tsutsugamushi disease. Significant increases in levels of tumor necrosis factor alpha were observed during the convalescent phase in five patients, and they exceeded the levels observed during the acute phase. H...

A cell line (designated BMpXT1) was generated from sheep bone marrow using the Moloney murine leukemia virus-based retroviral vector pXT1. BMpXT1 cells resembled mature alveolar macrophages in being adherent and esterase positive, in expressing certain cell surface antigens, and in secreting granulocyte-macrophage colony-stimulating factor (GM-CSF) when stimulated by ovine interferon-gamma and ...

Experiments in which immobilised restriction fragments of genomic DNA were hybridised with a cloned human fibroblast interferon cDNA indicate that the homologous chromosomal genes exist in only one basic arrangement. This is in marked contrast to recent studies by Nagata et al. (1) showing that there are at least eight gene arrangements for human leukocyte interferon. Having isolated a chromoso...

Mycobacterium lepraemurium grew progressively in monolayers of Proteose Peptone-elicited macrophages from C57BL/6 mice. Treatment of macrophage monolayers with gamma interferon led to an enhancement of growth of M. lepraemurium in macrophages. Treatment with tumor necrosis factor alpha or granulocyte-macrophage colony-stimulating factor led to restriction of mycobacterial growth in macrophages.
