Alphavirus Transducing Systems
2008Alphavirus transducing systems (ATSs) are important tools for expressing genes of interest (GOI) in mosquitoes and nonvector insects. ATSs are derived from infectious cDNA clones of mosquito-borne RNA viruses (family Togaviridae). The most common ATSs in use are derived from Sindbis viruses; however, ATSs have been derived from other alphaviruses as ...

Current Opinion in Biotechnology, 1994
Alphavirus vectors are newcomers in the field of heterologous gene expression. Nevertheless, they have rapidly become popular and are now being used in a wide range of applications. During the past year, new vectors and new methods for their use have improved levels of gene expression.

Purification and Concentration of Alphavirus
Cold Spring Harbor Protocols, 2012The alphaviruses Semliki Forest virus and Sindbis virus have been used frequently as expression vectors in vitro and in vivo. Usually, these systems consist of replication-deficient vectors that require a helper vector for packaging of recombinant particles. Replication-proficient vectors have also been engineered.

Publisher Summary This chapter describes the mechanics, including how alphaviruses function as expression vectors and some features that make them useful. It also describes some of the ways in which alphaviruses have been used and some potential ways they can be of value. Alphaviruses are positive-strand RNA-enveloped viruses.

An eruption associated with alphavirus infection
British Journal of Dermatology, 1996Some alphaviruses, e.g. Sindbis, cause an acute febrile illness associated with papular rashes and arthralgia. The diagnosis is usually serological and, hence, the histopathology of the rashes has been poorly elucidated. We report on two patients with rapidly healing eruptions associated with Sindbis virus infection.

Alphavirus-Based Antigen Preparation
2020Alphavirus-based vectors present an efficient approach for antigen preparation applied for vaccine development. Semliki Forest virus, Sindbis virus, and Venezuelan equine encephalitis virus have been engineered for high-level expression of antigens targeting infectious diseases and tumors.

Alphavirus Hybrid Virion Vaccines
1996Many members of the alphavirus family are important human or veterinary pathogens. These viruses are extremely similar in molecular architecture yet differ in host range and in the pathological consequences of infection. Despite marked structural conservation, the various species are inefficient in eliciting immunological cross protection. Previously(l)

The effects of alphavirus infection on neurons
Annals of Neurology, 1994Sindbis virus is an alphavirus that causes encephalitis in mice. The primary target cells for central nervous system infection are neurons. The outcome of neuronal infection is dependent on the age of the mouse at the time of infection (maturity of the neuron) and the strain of virus used for infection (virulence of the virus).

Alphavirus Entry into Host Cells
2015Viruses have evolved to exploit the vast complexity of cellular processes for their success within the host cell. The entry mechanisms of enveloped viruses (viruses with a surrounding outer lipid bilayer membrane) are usually classified as being either endocytotic or fusogenic.

The regulation of disassembly of alphavirus cores
Archives of Virology, 2009Alphaviruses are used as model viruses for structure determination and for analysis of virus entry. They are used also as vectors for protein expression and gene therapy. Virus particles are assembled by budding, using preformed cores and a modified cellular membrane. During entry, alphaviruses release the viral core into the cytoplasm.
