    摘要: Fusion antigen used as vaccine and method of making them. The method includes: (1) selecting a segment of a virus protein sequence that contains a least one epitope; (2) engineering a DNA fragment encoding the selected segment of the virus protein; (3) inserting the DNA fragment into a Pseudomonas Exotoxin A (PE) vector to obtain a chimeric gene plasmid, and expressing the chimeric gene plasmid in a host cell to obtain the chimeric vaccinal virus antigen. The PE vector contains a PE fragment, which has a binding domain and a translocating domain, and a carboxyl terminal moiety, which includes an endoplasmic reticulum retention sequence. The DNA fragment encoding the selected segment of the virus protein is inserted between the PE fragment and the carboxyl terminal moiety.

    摘要: Fusion antigen used as vaccine. The invention relates to a fusion antigen specific for a target cell. The fusion antigen contains a ligand moiety, a Pseudomonas exotoxin A translocation domain II, an antigenic moiety, and a carboxyl terminal moiety. The ligand moiety is capable of reacting, recognizing or binding to receptors on the target cell. The carboxyl terminal moiety permits retention and processing of the fusion antigen in the endoplasmic reticulum (ER) membrane of the target cell. Pharmaceutical compositions and methods of inducing an immune response using the same are also disclosed.
