Provided herein are compositions and methods for regulating expression of effector molecules using regulatable transcription factors and/or activation inducible promoters.

Provided are methods of making and delivering vaccine compositions using an enucleated cell-based platform. Methods of clearing pathogenic infections in a subject using the enucleated cell-based platform is also provided. Such enucleated cell-based platform reduces the vaccine development timeline as compared with conventional biological vaccines, and improves vaccine efficacy.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding a polypeptide; viruses comprising the recombinant nucleic acids; compositions comprising the recombinant nucleic acids and/or viruses; methods of their use; and articles of manufacture or kits thereof.

The present invention relates to oncolytic virus comprising: (i) a GM-CSF-encoding gene; and (ii) an immune co-stimulatory pathway activating molecule or an immune co-stimulatory pathway activating molecule-encoding gene.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding a Serine Protease Inhibitor Kazal-type (SPINK) polypeptide (e.g., a SPINK5 polypeptide); viruses comprising the recombinant nucleic acids; compositions and formulations comprising the recombinant nucleic acids and/or viruses; methods of their use (e.g., for the treatment of Netherton Syndrome); and articles of manufacture or kits thereof.

Malignant tumors that are resistant to conventional therapies represent significant therapeutic challenges. An embodiment of the present invention provides a codon optimized new generation 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 present disclosure provides a system for the expression of target protein in conjunction with enhancer protein. The enhancer protein may be a viral protein that blocks nucleocytoplasmic transport. Also provided are polynucleotides, vectors, and cells comprising target protein and enhancer protein nucleic acid sequences.

The present invention generally relates to the field of herpesviruses and herpesvirus proteins that can be used for the production of antibodies or therapeutic agents, such as vaccines. More specifically, the present invention relates to a modified herpesvirus glycoprotein B that comprises one or more mutations at defined positions in the primary structure of the protein which retain a stable prefusion conformation which is highly advantageous for the production of antibodies or therapeutic agents, such as vaccines. The invention further relates to nucleic acid molecules which encode such a modified herpesvirus glycoprotein B. The invention further provides methods for producing antibodies or therapeutic agents, such as vaccines, which make use of the modified herpesvirus glycoprotein B or a nucleic acid molecule encoding it. Kits comprising the modified herpesvirus glycoprotein B are provided as well. Finally, the invention also relates to the use of the modified herpesvirus glycoprotein B or a nucleic acid molecule encoding same for drug screening.

Provided herein are compositions and methods for vaccination and research applications. In particular, provided herein are non-neuroinvasive herpesviruses and alpha herpesviruses and uses thereof.

Chimeric protein constructs including a herpesvirus glycoprotein D (gD) and a heterologous polypeptide that interact with herpes virus entry mediator (HVEM) and enhance and enhance an immune response against the heterologous polypeptide and methods for their use are provided.
