  • Patent number: 10172931
    Abstract: A recombinant baculovirus displaying on its envelop a fusion protein is disclosed. The fusion protein comprises a heterologous antigen, and a C-terminal region of baculovirus envelope GP64 protein, which has at least 100 amino acid residues in length and lacks a B12D5 binding epitope located within the central basic region of the GP64 protein. The genome of the recombinant baculovirus comprises a transgene encoding a fusion protein that comprises a signal peptide, the heterologous antigen, and the C-terminal region of the baculovirus envelope GP64 protein, in which the antigen is located between the signal peptide and the C-terminal region of the GP64 protein. Methods for eliciting an antigen-specific immunogenic response in a subject in need thereof are also disclosed.

  • Patent number: 10010602
    Abstract: A fusion protein comprising an antigen-presenting cell (APC)-binding domain or a CD91 receptor-binding domain, a translocation peptide, a fusion antigen, an endoplasmic reticulum retention sequence, and optionally a nuclear export signal is disclosed. The fusion antigen comprises a porcine reproductive and respiratory syndrome virus (PRRSV) ORF7 antigen, a PRRSV ORF1b antigen, a PRRSV ORF6 antigen, and a PRRSV ORF5 antigen.
