A polypeptide termed oncostatin M, which inhibits the replication of A375 melanoma and other human tumor cells, but not normal human fibroblasts, has been isolated from serum-free supernatants of U-937 histiocytic lymphoma cells that have been induced to differentiate into macrophage-like cells following treatment with the phorbol ester phorbol 12-myristate(More)
Functional impairment and selective depletion of CD4+ T cells, the hallmark of AIDS, are at least partly caused by human immunodeficiency virus (HIV-1) type 1 binding to the CD4 molecule and infecting CD4+ cells. It may, therefore, be of therapeutic value to target an antiviral agent to CD4+ cells to prevent infection and to inhibit HIV-1 production in(More)
In a randomised phase I trial of a recombinant vaccina virus vaccine expressing the gp160 envelope gene of the human immunodeficiency virus (HIVAC-1e) 35 healthy, HIV-seronegative males, 31 of whom had a history of smallpox immunisation and 4 of whom were vaccinia naive, were vaccinated and then boosted 8 weeks later with HIVAC-1e or standard NY strain(More)
Natural killer (NK)6 cell activity of peripheral blood lymphocytes against human leukemia cell lines was measured in patients with chronic B-cell lymphocytic leukemia (CLL) and age- and sex-matched controls. In order to remove the leukemia cells that interfere with the in vitro assay we (1) isolated lymphocytes that form rosettes with sheep red blood cells(More)
Simian immunodeficiency virus (SIV) is a primate lentivirus related to human immunodeficiency viruses and is an etiologic agent for acquired immunodeficiency syndrome (AIDS)-like diseases in macaques. To date, only inactivated whole virus vaccines have been shown to protect macaques against SIV infection. Protective immunity was elicited by recombinant(More)
Oncostatin M is a novel growth regulator originally isolated from differentiated human histiocytic lymphoma cells and activated T-lymphocytes based on its ability to inhibit the growth of A375 melanoma cells. We report here that oncostatin M is a widely acting regulator which alters the growth and/or morphology of cells derived from a variety of cancer cell(More)
Recombinant human immunodeficiency virus type-1 (HIV-1)-like gag-env particles produced in mammalian cells were inoculated into two New Zealand white rabbits. In parallel, two control rabbits were inoculated with the homologous HIV-1 virions inactivated by ultra violet light (uv) and psoralen treatments. The humoral and cellular immune responses to HIV-1(More)
