Description

A kind of swine fever virus epiposition vaccine and preparation method thereof
The present invention relates to vaccine with the biotechnology preparation and preparation method thereof, particularly relate to a kind of classical swine fever virus vaccine and preparation method thereof.
Swine fever is that (HCV) the pernicious communicate illness of Yin Faing is in case outburst often brings enormous economic loss at short notice for Classical Swine fever virus, CSFV or Hog Choleravirus by swine fever virus.As far back as the fifties, China has just developed hog cholera lapinised virus vaccine, this vaccine is a kind of of attenuated live vaccine, utilize the live hog Pestivirus behind the attenuation to come the induction of immunity protection, controlled swine fever being very popular and distributing effectively in China, fine because of its safety and preventive effect, many countries also use this vaccine.Enter the later stage seventies, swine fever popular with distribute with chronic infection be feature, and the immuning failure phenomenon generally appears.Fact proved, when the swine fever that the swine fever virus that existing hog cholera lapinised virus vaccine morphs at pre-Radix Stephaniae Tetrandrae causes is popular, exist very big difficulty.The swine fever virus subunit vaccine is a kind of swine Fever Vaccine of developing both at home and abroad at present, and this vaccine is to utilize the virus envelope protein of gene recombinaton to come the induction of immunity protection.Though this vaccine can tackle the variation of swine fever virus to a certain extent, only comprise a hereditary information of virus in the vaccine, when virus morphed, this vaccine promptly can lose effectiveness, and the production cost of this vaccine is still higher at present.
On the other hand, the antigenic region sequence on the swine fever virus envelope protein E 2 (690-866 amino acids residue) be proved can induction of immunity protection, (Vaccine 2000,18:2351 can to protect the infection of pig prevention swine fever virus; Vaccine 1999,17:433; J.Virology 1995,69:6479; Vaccine 2000,18:1374; J.Virology 1993,67:5435).
Simultaneously, the present inventor discovers that the epitope polypeptide of multi-epitope can be induced the neutralizing antibody of high titre, predefined, many neutralizing epitope and variant epitope epitope specificity.
The purpose of this invention is to provide a kind of swine fever virus epiposition vaccine that can do with the swine fever virus variation.
Another object of the present invention provides a kind of method of producing above-mentioned swine fever virus epiposition vaccine.
For achieving the above object, the present invention takes following design: a kind of swine fever virus epiposition vaccine, it comprise at least one be coupled on carrier protein or the carrier polypeptide form coupling matter contain at least once the multiple single epi-position or the epitope polypeptide of multiple multi-epitope at least once, described epi-position is selected from neutralizing epitope and the variant epitope on the swine fever virus envelope protein E 2.
Neutralizing epitope on the described swine fever virus envelope protein E 2 or variant epitope are positioned at the antigenic region on the swine fever virus envelope protein E 2.
More particularly, described antigenic region is the 690-866 amino acids residue on the swine fever virus envelope protein E 2.
Described neutralizing epitope can be selected from:
RRYLASLH
SVTFEL

In order to make vaccine can induce stronger immunity, also comprise acceptable medicinal adjuvant in the vaccine.
A kind of method for preparing above-mentioned swine fever virus epiposition vaccine consists essentially of following steps:
(1), synthetic at least one contains at least once the epitope polypeptide of the single neutralizing epitope of antigenic region on the multiple swine fever virus envelope protein E 2 or single variant epitope or a plurality of neutralizing epitope or a plurality of variant epitope or a plurality of neutralizing epitope and variant epitope;
(2), above-mentioned epitope polypeptide is coupled to respectively on carrier protein or the carrier polypeptide forms coupling matter;
(3), above-mentioned coupling matter is equipped with acceptable adjuvant and is prepared into the swine fever virus epiposition vaccine.
The polypeptide of described synthetic can be selected from:
