A BVP8 protein for killing tetranychid mites and use thereof are provided. The protein is as set forth in SEQ ID NO. 2. The BVP8 protein has a median lethal concentration of 12.98 μg/mL against Tetranychus urticae, 33.45 μg/mL against Panonychus citri, and 26.32 μg/mL against Tetranychus cinnabarinus, and shows an inhibitory effect against the hatching and cleavage of Tetranychus urticae eggs, with the egg cleavage rate of 75.86% after 72 h. The protein provides a new option for the preparation of a novel miticide.

A recombinant BHV-1 oncolytic virus is provided comprising a BHV-1 mutant with enhanced cancer selectivity and/or enhance immunostimulatory activity as compared to wildtype BHV-1. The BHV-1 mutant is genetically modified to express one or more immunomodulatory molecules that induce an anti-tumor immune response. A method of generating the recombinant BHV-1 oncolytic virus is also provided.

Aspects of the disclosure relate to nucleic acid vaccines. The vaccines include at least one RNA polynucleotides having a open reading reading frame encoding at least varicella zoster virus (VZV) antigen. Methods for preparing and using such vaccines are also described.

Provided are recombinant nucleic acids (e.g., vectors), and related methods, for expression of a target gene in a host cell. The recombinant nucleic acids comprise a promoter comprising a nucleic acid sequence having at least 70% sequence identity to a sequence selected from SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8 and SEQ ID NO: 9; a cloning site for insertion of a nucleic acid encoding the target gene; and at least one non-promoter regulatory element required for the expression of the target gene in the host cell.

The present disclosure discloses a recombinant varicella-zoster virus (VZV) vaccine, including a fusion protein formed by an amino acid sequence of an extracellular domain of a recombinant glycoprotein gE of a live attenuated VZV strain (OKA strain) gene and an Fc fragment of human immunoglobulin. The present disclosure further provides preparation and use of the fusion protein, a corresponding recombinant gene, a eukaryotic expression vector, etc. The fusion protein of the present disclosure has prominent immunogenicity and can induce the high-level expression of neutralizing antibodies in serum.

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.

The present invention relates to a Varicella zoster virus fusion protein and an immunogenic composition comprising same and, more specifically, to a fusion protein comprising the glycoprotein E (gE) of Varicella zoster virus (VZV) and a constant region of an immunoglobulin molecule, and an immunogenic composition comprising same. The present invention not only remarkably increases a Varicella zoster virus-specific cell-mediated immune response, but also exhibits the effect of rapidly and potently inducing an immune response and sustaining the immune response for a long period of time, compared to preexisting vaccines, thereby can be usefully used to prevent Varicella zoster-related diseases.

Aspects of the disclosure relate to nucleic acid vaccines. The vaccines include at least one RNA polynucleotides having an open reading frame encoding at least one varicella zoster virus (VZV) antigen. Methods for preparing and using such vaccines are also described.

An antigen variant and a use thereof are disclosed. The antigen variant is a protein, among surface proteins (gE) of the varicella zoster virus, exhibits a high expression level and high immunogenicity, and thus, when the antigen variant is used as a vaccine composition, the vaccine composition has more excellent safety compared to a live virus vaccine, and the antigen variant exhibits a higher expression level in a host cell compared to other antigens. The antigen variant is useful as a vaccine for preventing or treating chicken pox or herpes zoster caused by the varicella zoster virus.

A modified Herpes Simplex Virus (HSV), which has a portion of gD (glycoprotein D) of the glycoproteic envelope deleted and a heterologous single chain antibody inserted in place of such deleted portion; the modified HSV is capable of infecting cells through receptor HER2/ErbB2 but not through receptors HVEM/HveA and nectin1/HveC; uses of the modified HSV and a process of the preparation thereof are also disclosed.
