摘要:
The present invention relates to an adjuvant composition containing poly-gamma-glutamic acid-chitosan nanoparticles and a vaccine composition containing the adjuvant composition, and more particularly to an adjuvant composition containing nanoparticles prepared by ionic bonding between poly-gamma-glutamic acid having ensured safety and chitosan, and a vaccine composition containing the poly-gamma-glutamic acid-chitosan nanoparticles and an antigen. The adjuvant containing the poly-gamma-glutamic acid-chitosan nanoparticles has little or no toxicity and side effects and is added to human or animal vaccines for the prevention and treatment of viral and bacterial infections and cancers to increase the production of antibodies.
摘要:
The present invention relates to a surface expression vector of SARS coronavirus antigen containing a gene encoding an antigen of SARS inducing coronavirus and any one or two or more of genes pgsB, pgsC and pgsA encoding poly-gamma-glutamic acid synthase complex, a microorganism transformed by the surface expression vector, and a SARS vaccine comprising the microorganism. According to the present invention, it is possible to economically produce a vaccine for prevention and treatment of SARS using a recombinant strain expressing an SARS coronavirus antigen on their surface.
