A method of preparing a mouse model of herpes using a herpes simplex virus and hydrocortisone, and a mouse model of herpes prepared the method are disclosed. When the preparation method is used, an animal model in which the symptoms of herpes clearly appear can be prepared, and thus the animal model can be widely used in the development of therapeutic agents for herpes simplex virus infection. A use of the mouse model in screening and developing a candidate therapeutic agent is also disclosed.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding one or more cosmetic proteins (e.g., one or more human collagen proteins); viruses comprising the recombinant nucleic acids; compositions (e.g., cosmetic formulations) comprising the recombinant nucleic acids and/or viruses; methods of their use; and articles of manufacture or kits thereof.

The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding one or more cosmetic proteins (e.g., one or more human collagen proteins); viruses comprising the recombinant nucleic acids; compositions (e.g., cosmetic formulations) comprising the recombinant nucleic acids and/or viruses; methods of their use; and articles of manufacture or kits thereof.

Provided are a promoter of a gene specifically expressed in fetal trophoblast cells and a gene specifically expressed in fetal nucleated red blood cell-specific expression gene, as well as a recombinant herpes simplex virus type I obtained by replacing the wild type promoter of the genomic ICP of the recombinant herpes simplex virus type I with the aforesaid promoter and preparation and use thereof. Also provided are a diagnostic kit for prenatal screening and use thereof, as well as a method for isolating fetal cells from a maternal blood sample in pregnancy.
