HIGHLY PATHOGENIC AVIAN INFLUENZA VIRUS PROTEIN VACCINE DERIVED FROM TRANSGENIC PLANTS, AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a method for producing transgenic plants, which involves producing hemagglutinin proteins of the H5N1 virus in a highly efficient manner using a plant transformation recombinant vector, wherein said vector can express, in a highly efficient manner, hemagglutinin proteins of the H5N1 virus which is the highly pathogenic avian influenza virus, and can transport proteins expressed in plants to the endoplasmic reticulum and enable the retention of the proteins in the endoplasmic reticulum so as to accomplish glycosylation which is necessarily required for antigen activity. The present invention also relates to a method for the mass production of hemagglutinin proteins of the antigenic H5N1 virus from the transgenic plants, and to a vaccine composition for the avian influenza virus comprising the transgenic plants or the hemagglutinin proteins produced from the plants. The method for producing hemagglutinin proteins of the H5N1 virus using transgenic plants according to the present invention enables the mass production of hemagglutinin proteins at a low cost. The plant transformation recombinant vector used in the present invention has a cellulose-binding domain inserted therein to separate proteins expressed in plants in a quick and easy manner. In addition, transgenic plants according to the present invention can be taken in the form of feed additives or the like, and therefore can be used as edible vaccines. Further, antigenic hemagglutinin proteins produced by the method induce immune response when administered to an animal model, and therefore can be used not only as protein vaccines for the H5N1 avian influenza virus, but also as diagnostic reagents for avian influenza virus infection.
