Plasmid DNA-based Alphavirus Vaccines
Vaccines, 2019 Alphaviruses have been engineered as vectors for high-level transgene expression. Originally, alphavirus-based vectors were applied as recombinant replication-deficient particles, subjected to expression studies in mammalian and non-mammalian cell lines,

The adjuvant activity of alphavirus replicons is enhanced by incorporating the microbial molecule flagellin into the replicon. [PDF]
PLoS ONE, 2013 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

Selective precipitation reaction: a novel diagnostic test for tissue pathology in Atlantic Salmon, Salmo salar, infected with Salmonid Alpha-Virus (SAV3) [PDF]
, 2017 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 ...

Knockdown of piRNA pathway proteins results in enhanced Semliki forest virus production in mosquito cells [PDF]
, 2013 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

Synthesis of Alphavirus-Specified RNA [PDF]
Journal of Virology, 1978 UV irradiation of chicken fibroblasts infected with Semliki Forest or Sindbis virus has been used to investigate the mechanism of synthesis of 42S and 26S RNA, the major plus-strand virus-specified RNAs formed during the multiplication of standard virus particles.

Alphavirus polymerase and RNA replication [PDF]
Virus Research, 2017 Alphaviruses are typically arthropod-borne, and many are important pathogens such as chikungunya virus. Alphaviruses encode four nonstructural proteins (nsP1-4), initially produced as a polyprotein P1234. nsP4 is the core RNA-dependent RNA polymerase but all four nsPs are required for RNA synthesis.

Sequestration of G3BP coupled with efficient translation inhibits stress granules in Semliki Forest virus infection [PDF]
, 2012 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

Alphavirus Restriction by
Traffic, 2016 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.

ZAP's stress granule localization is correlated with its antiviral activity and induced by virus replication. [PDF]
, 2019 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 ...
