Malignant tumors that are resistant to conventional therapies represent significant therapeutic challenges. An embodiment of the present invention provides a regulatable fusogenic oncolytic herpes simplex virus-1 that is more effective at selective killing target cells, such as tumor cells. In various embodiments presented herein, the oncolytic virus described herein is suitable for treatment of solid tumors, as well as other cancers.

The nucleotide and amino acid sequences of indoleamine 2,3-dioxygenase-2 (IDO2) and methods of use thereof are provided.

The invention relates to retroviral producer cell comprising nucleic acid sequences encoding: gag and pol proteins; envelope protein or a functional substitute thereof; amplifiable selection marker; and the RNA genome of the retroviral vector particle, wherein said nucleic acid sequences are all integrated at a single locus within the retroviral producer cell genome. The invention also relates to nucleic acid vectors comprising a non-mammalian origin of replication and the ability to hold at least 25 kilobases (kb) of DNA, characterized in that said nucleic acid vector comprises retroviral nucleic acid sequences encoding: gag and pol proteins, and an env protein or a functional substitute thereof. The nucleic acid vector additionally comprises nucleic acid sequences encoding an amplifiable selection marker. The invention also relates to uses and methods using said nucleic acid vector in order to produce stable retroviral packaging and producer cell lines.

The present disclosure provides a method of generating a stable producer cell line. The generation of stable producer cell lines, such as those provided in accordance with the present invention, increases the reproducibility and ease of creating high titer lentiviral stocks while easing biosafety concerns and the variation in expressed envelope proteins defines the tropism of the generated virus. The present disclosure also provides for a novel lentiviral transfer vector plasmid.

Disclosed herein are compositions that include modified adenoviruses. Also disclosed are nucleotides, cells, and methods associated with the compositions including their use as vaccines. Also disclosed herein are viral vectors using TET promoter system and methods of producing viruses having the same.

Provided herein are adenoviral vectors comprising nucleotide sequences encoding a Zika virus M and Env antigen, wherein the nucleotide sequence encoding the Zika virus M and Env antigen is operably linked to a cytomegalovirus (CMV) promoter comprising at least one tetracycline operator (TetO) motif. Also provided herein are pharmaceutical compositions comprising the adenoviral vectors, methods of producing the adenoviral vectors, methods of preventing Zika virus or the progression of Zika virus in a subject in need thereof, and kits comprising the adenoviral vectors and host cells.

The invention provides an AoHV-1 promoter for use with plasmid vectors, viral vectors, viruses, and cell lines comprising the AoHV-1 promoter operably linked to a transgene. The invention also provides methods of making and using recombinant plasmid vectors, viral vectors, viruses, and cell lines comprising the AoHV-1 promoter operably linked to a transgene.

Described herein are methods and compositions for autocatalytic genome editing and neutralizing autocatalytic genome editing. The autocatalytic genome editing may be based on genomic integration of a construct containing multiple elements or on a trans-complementation approach, in which genetic elements can be propagated separately. The disclosure provides a method for autocatalytic genome editing based on the CRISPR/CAS9 system, and methods of use thereof, in animals, humans, and plants for eliminating pathogens, targeting suppression of crop pests, strategies to combat virus (e.g., HIV) and other diseases (e.g., cancer) caused by retrovirus, as well as to generate homozygous mutations that are transmitted to nearly all offspring.

Two or more conditional, dominant, lethal gene expression systems provide high levels of penetrance in insects. Lethality is induced at an earlier stage of development and the risk of biochemical resistance is reduced, as compared to a single insect conditional, dominant, lethal gene expression system. The invention is useful for the control of insect populations.
