The interferon-stimulated gene IFITM3 restricts infection and pathogenesis of arthritogenic and encephalitic alphaviruses [PDF]
Host cells respond to viral infections by producing type I interferon (IFN), which induces the expression of hundreds of interferon-stimulated genes (ISGs).

Capping pores of alphavirus nsP1 gate membranous viral replication factories
Positive-sense single-stranded RNA viruses, such as coronaviruses, flaviviruses and alphaviruses, carry out transcription and replication inside virus-induced membranous organelles within host cells 1 – 7 .

Production of virus-derived ping-pong-dependent piRNA-like small RNAs in the mosquito soma. [PDF]
The natural maintenance cycles of many mosquito-borne pathogens require establishment of persistent non-lethal infections in the invertebrate host. The mechanism by which this occurs is not well understood, but we have previously shown that an antiviral ...

Selective precipitation reaction: a novel diagnostic test for tissue pathology in Atlantic Salmon, Salmo salar, infected with Salmonid Alpha-Virus (SAV3) [PDF]
While investigating biomarkers for infection with salmonid alphavirus (SAV), the cause of pancreas disease (PD), a selective precipitation reaction (SPR) has been discovered in serum which could be an on-farm qualitative test and an in-laboratory ...

The adjuvant activity of alphavirus replicons is enhanced by incorporating the microbial molecule flagellin into the replicon. [PDF]
Ligands of pattern recognition receptors (PRRs) including Toll-like receptors (TLRs) stimulate innate and adaptive immune responses and are considered as potent adjuvants. Combinations of ligands might act in synergy to induce stronger and broader immune

Apoptosis in Alphavirus Encephalitis
Abstract Sindbis virus causes acute encephalitis in mice and serves as a useful model for encephalitic alphaviruses that infect humans. The outcome of infection is determined by whether infected neurons are resistant to virus-induced programmed cell death or activate their apoptotic pathway.

Knockdown of piRNA pathway proteins results in enhanced Semliki forest virus production in mosquito cells [PDF]
The exogenous siRNA pathway is important in restricting arbovirus infection in mosquitoes. Less is known about the role of the PIWI-interacting RNA pathway, or piRNA pathway, in antiviral responses. Viral piRNA-like molecules have recently been described

Alphavirus Restriction by
Interferon inducible transmembrane proteins (IFITMs) are broad‐spectrum antiviral factors. In cell culture the entry of many enveloped viruses, including orthomyxo‐, flavi‐, and filoviruses, is inhibited by IFITMs, though the mechanism(s) involved remain unclear and may vary between viruses.

Sequestration of G3BP coupled with efficient translation inhibits stress granules in Semliki Forest virus infection [PDF]
Dynamic, mRNA-containing stress granules (SGs) form in the cytoplasm of cells under environmental stresses, including viral infection. Many viruses appear to employ mechanisms to disrupt the formation of SGs on their mRNAs, suggesting that they represent

ZAP's stress granule localization is correlated with its antiviral activity and induced by virus replication. [PDF]
Cellular antiviral programs encode molecules capable of targeting multiple steps in the virus lifecycle. Zinc-finger antiviral protein (ZAP) is a central and general regulator of antiviral activity that targets pathogen mRNA stability and translation ...
