Chronic induction of interferon by continuous infusion of polyriboinosinic:polyribocytidilic acid. 1985

S A Rothmann, and P Paul, and T J Oluic', and K A Sturkie, and M R Proffitt

In an attempt to induce circulating interferon (IFN) chronically, C57BL/6 or Balb/cBy mice received daily injections or continuous infusion of polyriboinosinic:polyribocytidilic acid [poly(I:C)] i.p. for 7 days. Significantly higher plasma IFN was present in C57BL/6 mice receiving poly(I:C) via continuous infusion compared with daily injections. Spleen and bone marrow natural killer (NK) cells were elevated only in the group receiving poly(I:C) continuously. Little IFN was induced acutely in Balb/cBy mice and none was present after chronic infusion of poly(I:C). NK cells were not elevated. Continuous infusion of poly(I:C) appears to overcome the hyporesponsiveness to repeated IFN induction in a susceptible mouse strain.

UI MeSH Term Description Entries
D007372 Interferons Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions. Interferon
D007694 Killer Cells, Natural Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.
