Effect of Poly I:C/poly-L-lysine (poly ICL) on the Development of Murine Osteogenic Sarcoma

Journal of Interferon Research, 1983
Poly I:C/poly-L-lysine (poly ICL) was effective in preventing or delaying the development of osteogenic sarcoma (OGS) in mice. C57BL/6J mice were inoculated subcutaneously with 5 X 10(4) OGS cells and treatment was evaluated by palpable tumor development and subsequent day of death.

The reduction of voluntary physical activity after poly I:C injection is independent of the effect of poly I:C-induced interferon-beta in mice

Physiology & Behavior, 2008
One characteristic of sickness behavior in mice is demonstrated by a reduction in voluntary wheel-running activity during infection. Among synthetic double-stranded (ds) RNAs, polyriboinosinic: polyribocytidylic acid (poly I:C) activates to produce interferon (IFN) -beta, which plays an important role in anti-viral activity and host-defense.

Electrochemical Probing of Dopamine Dynamics During Poly(I:C)‐Induced Neuroinflammation

Small
AbstractViruses can infiltrate the central nervous system and contribute to depression, which may include alterations in dopamine (DA) metabolism triggered by immune responses though the specific mechanisms involved remain unclear. Here, an electrochemical system to realize the real‐time dynamic monitoring of DA with high sensitivity is proposed and it

Loading of Acute Myeloid Leukemia Cells with Poly(I:C) by Electroporation

2014
In this chapter, we describe the technique of electroporation as an efficient method to load primary leukemic cells with the double-stranded RNA (dsRNA) analogue, polyriboinosinic polyribocytidylic acid (poly(I:C)), and detail on the delicate freezing and thawing procedure of primary leukemic cells.Electroporation is a non-viral gene transfer method by

The Effect of Actinomycin D on the Lethality of Poly I:C

The Journal of Immunology, 1971
Abstract Poly I:C, a synthetic double-stranded RNA composed of polyinosinic and polycytidylic acids, has become the subject of intense investigation because of its capacity to induce interferon formation and exert antineoplastic activity in experimental animals (1–4).

Double-Stranded RNAs (Poly I:C) in the Prevention of Viral Infections

Archives of Internal Medicine, 1970
The effective control of viral diseases is a difficult problem and necessitates the exercise of opportunism to explore and utilize all possible approaches. Certain of the viruses for which there is a single or few serotypes lend themselves well to control by vaccines as, eg, poliomyelitis, measles, mumps, rubella, yellow fever, influenza, and smallpox.

The mechanism of poly I:C-induced antiviral activity in peritoneal macrophage

Archives of Pharmacal Research, 1994
Macrophages play an important role in defense against virus infection by intrinsic resistance and by extrinsic resistance. Since interferon-induced enzymes which are 2'-5' oligoadenylate synthetase and P1/eIF-2 protein kinase have been shown to be involved in the inhibition of viral replication, I examined the mechanism by which poly I:C, an interferon

Effect of poly I:C on cell proliferation in vivo.

Archivum immunologiae et therapiae experimentalis, 1978
Female Swiss albino mice were injected intraperitoneally with poly I:C1 microgram/g body weight. The animals were killed 2, 12, and 24 hr after the injection of poly I:C. Half an hour before the death of animals they were reinjected intraperitoneally with 3H-thymidine. Fragments of ileum were excised.

Effects of poly I:C in porcine iron deficient neutropenia.

The Cornell veterinarian, 1985
Withholding iron dextran treatment normally given to pigs at 1-3 days of age to prevent anemia resulted also in neutropenia. Polyinosinic acid:polycytidylic acid (poly I:C) at 0.5 mg/kg IV at 25 days of age resulted in induction of putative interferon 2 to 24 hours later, with significantly (P less than 0.05) lower concentrations in iron-deficient (Fe-)
