  • Patent number: 11952401
    Abstract: The present disclosure belongs to the technical field of biological products for veterinary medicine, and specifically relates to a recombinant foot-and-mouth disease virus (FMDV) with a reduced immunosuppressive activity, a preparation method and use thereof, and a recombinant vaccine strain. According to the present disclosure, it is firstly discovered that FMDV 3B protein has an immunosuppressive function, and key sites for exerting the immunosuppressive function are found. A recombinant FMDV vaccine strain with a lost immunosuppressive function in FMDV 3B protein is constructed by introducing amino acid mutations into three repeated copies of FMDV 3B protein.

  • Patent number: 11926877
    Abstract: A saliva-based testing method that bypasses the need for RNA isolation/purification is described herein. In experiments with inactivated SARS-CoV-2 virus spiked into saliva, this method has a limit of detection of 500-1000 viral particles per mL, rivalling the standard NP swab method. Initial studies showed excellent performance with 100 clinical samples. This saliva-based process is operationally simple, utilizes readily available materials, and can be easily implemented by existing testing sites thus allowing for high-throughput, rapid, and repeat testing of large populations.

  • Patent number: 11834722
    Abstract: A method of determining the safety and/or efficacy of a gene therapy vector prior to carrying out gene therapy on an individual includes infecting a culture of induced pluripotent stem cells obtained from the individual with a gene therapy vector. Ideally the cells are allowed to differentiate, and the infection is carried out at the start of culture and at least once during differentiation and/or after differentiation. Nucleic acids are extracted from the infected cells, and then analysed to measure and/or determine adverse effects of integration of nucleic acid from the vector and/or efficiency of expression of nucleic acid from the vector.
