Interferon induction by avian reovirus

Avian reovirus infections.

Avian reoviruses are ubiquitous among poultry flocks. Although infection is usually present without disease, reoviruses may occasionally be involved in several disease syndromes of which viral arthritis/tenosynovitis in chickens is the most important, particularly in broiler breeds. While reoviruses have been isolated from turkeys and several other species of birds with various conditions, the ...

Interferon induction by adenoviruses.

All human, simian, bovine and avian adenovirus types tested so far and the canine hepatitis virus induce interferon production in chick cells. This finding indicated this property to be characteristic for viruses belonging to the adenovirus group. Trypsin treatment, which had no effect upon the infectivity, diminished or eliminated the interferon-inducing abilities of crude adenoviruses, and th...

Interferon production by double-stranded RNA: a comparison of induction by reovirus to that by a synthetic double-stranded polynucleotide.

Interferon Induction by Viruses

Interferons are proteins of cellular origin capable of conferring virus resistance to vertebrate cells. Most cells do not produce interferons except in response to proper stimulation. Clearly, the stimulation of interferon production encompasses two phenomena. When stimulated, some cell systems produce their interferons by synthesizing new proteins. Other cell systems do not require the synthes...

Proteolytic Disassembly of Viral Outer Capsid Proteins Is Crucial for Reovirus-Mediated Type-I Interferon Induction in Both Reovirus-Susceptible and Reovirus-Refractory Tumor Cells

Oncolytic reovirus induces innate immune responses, which contribute to the antitumor activity of reovirus, following in vivo application. Reovirus-induced innate immune responses have been relatively well characterized in immune cells and mouse embryonic fibroblasts cells; however, the mechanisms and profiles of reovirus-induced innate immune responses in human tumor cells have not been well u...
