Abstract: The present disclosure generally relates to viral-based expression systems suitable for the production of molecule of interests in recombinant host cells. The disclosure particularly relates to nucleic acid constructs, such as expression vectors, containing a modified arterivirus genome or replicon RNA in which at least some of its original viral sequence has been deleted. Also included in the disclosure are viral-based expression vectors including one or more expression cassettes encoding heterologous polypeptides. In some embodiments, the expression cassettes are configured and positioned at defined locations on the viral genome so as to enable expression of the heterologous polypeptides in a tunable manner.

Abstract: The invention provides RNA replicons useful for administering a heterologous protein or peptide into a mammal and eliciting a reduced immune response or no immune response from the mammal. The RNA replicons have RNA sequences encoding for a heterologous protein or peptide, New World alphavirus nonstructural proteins nsP1, nsP2, and nsP4; and an alphavirus nsP3 protein macro domain, central domain, and hypervariable domain. The encoded hypervariable domain can have an amino acid sequence derived from an Old World alphavirus nsP3 hypervariable domain; or can have an amino acid sequence derived from a portion of a New World alphavirus nsP3 hypervariable domain, and another portion derived from an Old World alphavirus nsP3 hypervariable domain.

Abstract: A method of quickly producing a vaccine for a biotype of pathogenic microorganism is described, where a nucleic acid molecule or fragment thereof is obtained from a biological sample from an animal exposed to the microorganism, a protective molecule is prepared based on the nucleic acid molecule of interest or fragment thereof, and administered to an animal which has been or is as risk of being exposed to the microorganism. A protective response to the biotype of the microorganism is obtained in the animal.
