Effect of cyclosporin A on the production of interferon by human peripheral blood leukocytes in vitro. 1982

J Abb, and H Abb, and F Deinhardt

Cyclosporin A (CsA) was assessed for its effect on the production of antiviral activity by human peripheral blood leukocytes (PBL). CsA markedly reduced the production of interferon-gamma (IFN-gamma) in response to stimulation with lectin mitogens, bacterial products, alloantigens, or Epstein-Barr virus (EBV)-transformed lymphoblastoid cell lines (LCL). CsA-mediated suppression of IFN-gamma secretion was dose-dependent and did not result from a shift of kinetics of the production of antiviral activity. The production of IFN-alpha in response to stimulation with Corynebacterium parvum (CP), viruses, and synthetic polynucleotides was not affected by the addition of CsA. These findings confirm earlier observations that CsA predominantly acts on T lymphocyte function. CsA may prove a valuable agent to study the role of IFN-gamma in the pathogenesis of virus-associated malignant lymphoproliferative disease.

UI MeSH Term Description Entries
D007370 Interferon Type I Interferon secreted by leukocytes, fibroblasts, or lymphoblasts in response to viruses or interferon inducers other than mitogens, antigens, or allo-antigens. They include alpha- and beta-interferons (INTERFERON-ALPHA and INTERFERON-BETA). Interferons Type I,Type I Interferon,Type I Interferons,Interferon, Type I,Interferons, Type I
D007371 Interferon-gamma The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES. Interferon Type II,Interferon, Immune,gamma-Interferon,Interferon, gamma,Type II Interferon,Immune Interferon,Interferon, Type II
D007519 Isoantigens Antigens that exist in alternative (allelic) forms in a single species. When an isoantigen is encountered by species members who lack it, an immune response is induced. Typical isoantigens are the BLOOD GROUP ANTIGENS. Alloantigens,Alloantigen,Isoantigen
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008934 Mitogens Substances that stimulate mitosis and lymphocyte transformation. They include not only substances associated with LECTINS, but also substances from streptococci (associated with streptolysin S) and from strains of alpha-toxin-producing staphylococci. (Stedman, 25th ed) Mitogen,Phytomitogen,Phytomitogens
D011070 Poly I-C Interferon inducer consisting of a synthetic, mismatched double-stranded RNA. The polymer is made of one strand each of polyinosinic acid and polycytidylic acid. Poly(I-C),Poly(rI).Poly(rC),Polyinosinic-Polycytidylic Acid,Polyinosinic-Polycytidylic Acid (High MW),Polyriboinosinic-Polyribocytidylic Acid,Polyribose Inosin-Cytidil,Inosin-Cytidil, Polyribose,Poly I C,Polyinosinic Polycytidylic Acid,Polyriboinosinic Polyribocytidylic Acid,Polyribose Inosin Cytidil
D011425 Propionibacterium acnes A bacteria isolated from normal skin, intestinal contents, wounds, blood, pus, and soft tissue abscesses. It is a common contaminant of clinical specimens, presumably from the skin of patients or attendants. Corynebacterium acnes,Corynebacterium parvum
D002460 Cell Line Established cell cultures that have the potential to propagate indefinitely. Cell Lines,Line, Cell,Lines, Cell
D002478 Cells, Cultured Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others. Cultured Cells,Cell, Cultured,Cultured Cell
D003524 Cyclosporins A group of closely related cyclic undecapeptides from the fungi Trichoderma polysporum and Cylindocarpon lucidum. They have some antineoplastic and antifungal action and significant immunosuppressive effects. Cyclosporins have been proposed as adjuvants in tissue and organ transplantation to suppress graft rejection. Cyclosporines
