    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.

    摘要: The present invention provides a PRRSV subunit vaccine comprising a fusion protein having neutralization titers evoked, PE-PQGAB-K3, which comprises a chimeric polypeptide containing N-terminal portions of PRRSV ORF5 and ORF6 structure proteins; a portion of Pseudomonas exotoxin A binding and translocation domain; and a carboxyl terminal domain containing KDEL-KDEL-KDEL(K3) sequence. Less inflammation of PE-PQGAB-K3 vaccine group in their lungs post being PRRSV-challenged indicates that PQGAB without an antigen-specific allergy effect. Importantly, PE-PQGAB-K3 vaccine presents a good protection against PRRSV infection than control groups in pig challenged experiment.

    摘要: Scopolamine is a folksy cholinergic antagonist, and is used by parasympathetic nerves in autonomic nervous neurons as an anti-motion sickness drug or an anti-emesis drug. Since the human body most effectively absorbs this drug through the postauricular skin, the drug is administered by postauricular transdermal resorption patch. The penetrability of drug is increase by adding a dermal penetrative enhancer, because the penetration ability of patch-administered drugs is usually decreased by the penetrative blockade at dermal horny layers. The present invention discloses a penetration enhancer to increase dermal absorption and penetration of the cholinergic antagonist. The present invention finds that polyethylene and amide enhance penetration, about 2.2-2.8 fold. In accordance with the present invention, a penetration enhancer is added to the formulations of transdermal patch to increase the human body's absorption of scopolamine.

    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.
