The present invention is in the field of Nipah virus (NiV) structural protein. Particularly, the invention provides structure based stabilized Nipah virus (NiV) structural protein designing and uses thereof.

The invention belongs to the field of gene engineering, and particularly relates to application of chikungunya virus structural protein in improvement of pseudovirus stability, a construction method of the chikungunya virus structural protein and vaccines, antibody evaluation and in-vivo gene therapy products. The method comprises the following steps: constructing a human codon optimized Asian strain CHIKV-E3 + E2 + 6K + E1 structural protein eukaryotic vector, and designing two types of binder expression plasmids of targeted T cells; the vector, a psPAX2 helper plasmid and a lentivirus target vector containing an SFFV promoter and a ZsGreen reporter gene (or a CAR therapeutic gene) are co-transformed into a 293T cell, and the lentivirus is prepared through culture, filtration and centrifugation. The lentivirus can efficiently infect Jurkat cells and activate human T cells, obviously reduces the infection efficiency on 293T cells so as to reduce the off-target effect, has excellent stability in human serum, and provides a safe and efficient gene delivery tool for in-vivo CAR-T therapy.

The invention relates to the technical field of biology, in particular to a porcine reproductive and respiratory syndrome virus subunit vaccine. Through bioinformatics analysis and experimental verification, the antigen protein with excellent immunogenicity is obtained through screening, and the amino acid sequence of the antigen protein is shown as SEQ ID NO: 1. The subunit vaccine constructed on the basis of the protein can effectively induce mice to generate high-level neutralizing antibodies, the effect of the subunit vaccine is remarkably better than that of commercial control vaccines, the mice can be stimulated to generate strong humoral immunity and cellular immunity at the same time, and the induced immune response type is mainly Th2 type. Further research shows that the antigen protein and the virus structural protein E + M are combined for immunization, and the immune effect of the structural protein can be remarkably enhanced. The subunit vaccine developed by the invention provides a new thought for research and development of novel vaccines for resisting PRRSV and other viral diseases.
