Patent number: 11952401Abstract: 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.Type: GrantFiled: July 14, 2021Date of Patent: April 9, 2024Assignee: Lanzhou Veterinary Research Institute, Chinese Academy of Agricultural SciencesInventors: Haixue Zheng, Fan Yang, Zixiang Zhu, Xiangle Zhang, Weijun Cao, Congcong Wang, Kangli Li, Huisheng Liu, Hong Tian, Keshan Zhang, Xiangtao Liu
