    摘要: The present invention is drawn to generating attenuated and less cytopathic forms of New World alphaviruses that can be used in immunogenic compositions as vaccines against both Old and New World alphaviruses. In this regard, the present invention discloses that the N-terminal, ˜35-aa-long peptide of VEEV, EEEV and, most likely, of WEEV capsid proteins plays the most critical role in the downregulation of cellular transcription and development of cytopathic effect. The identified, VEEV-specific peptide, CVEE30-68, includes two domains with distinguished functions. The integrity of both domains determines not only the intracellular distribution of CVEE, but is also essential for direct capsid function in the inhibition of transcription. The replacement of the N-terminal fragment of CVEE by its SINV-specific counterpart in VEEV TC-83 genome does not affect virus replication in vitro, but makes it less cytopathic and more attenuated in vivo.

    摘要: The present invention provides a Venezuelan equine encephalitis virus replicon RNA useful in the development of stable lines of mammalian, avian and insect cells in which these replicons will persistently replicate. Venezuelan equine encephalitis (VEE) virus replicons contain a number of unique adaptive mutations that make the replicons noncytopathic. The replicons remain resistant to IFN-α/β. Replicon replication leads to high-level production of heterologous proteins, which are encoded by the replicons' genome and are under the control of a viral subgenomic promoter. Also provided are methods of screening for inhibitory compounds of Venezuelan equine encephalitis virus replication and eastern equine encephalitis virus replication.
