The precise role of double-stranded (ds)RNA is still widely investigated as a central player in the Interferon System. Groups have found that positive-strand RNA viruses and dsRNA viruses produced significant amounts of dsRNA, but the precise methods mammalian cells leverage to distinguish between self vs. non-self dsRNA have yet to be uncovered.
A virus-infected cell releases viral particles that can infect nearby cells. However, the infected cell can protect neighboring cells against a potential infection of the virus by releasing interferons. In response to interferon, cells produce large amounts of an enzyme known as protein kinase R (PKR).
Viral interference is considered the most common outcome of coinfection, or the simultaneous infection of a host by two or more distinct viruses. [5] The primary form of viral interference is known as superinfection exclusion, in which the initial infection stimulates a resistance to subsequent infection by related viruses.

Tobacco mosaic virus was the first virus to be identified, as an infectious agent that could pass through porcelain filters, as well as the first to be crystallised. It was among the earliest virus structures to be modelled successfully. Credit: Thomas Splettstoesser (20 July 2012) Portal:Viruses/Selected picture/3
Type III interferon receptors are expressed more specifically on epithelial cells and some immune cells such as neutrophils, and depending on the species, B cells and dendritic cells as well. [ 13 ] [ 14 ] [ 15 ] Therefore, their antiviral effects are most prominent in barriers, in gastrointestinal, respiratory and reproductive tracts.
They form the genetic material of some viruses (double-stranded RNA viruses). dsRNA, such as viral RNA or siRNA, can trigger RNA interference in eukaryotes, as well as interferon response in vertebrates. [3] [4] [5] In eukaryotes, dsRNA plays a role in the activation of the innate immune system against viral infections. [1]
