Description
The present invention relates to bring out the peptide of the immunne response of anti-zona pellucida protein ZP3, with this peptide produce can with the purposes of the immunoreactive antibody of its generation, monoclonal antibody, can produce the hybridoma cell line of described antibody, the purposes that described peptide or described antibody is used to prepare pregnancy vaccine, the pregnancy vaccine that contains described peptide or antibody, described peptide is used for the purposes of the autoimmune antibody of the anti-ZP3 of test sample, contains the diagnostic kit of described antibody and be used for the test kit of the autoimmune antibody of the anti-ZP3 of test sample.
Zona pellucida (ZP) is the outer glycoprotein matrixs of the compound born of the same parents around the mammal ovocyte.This matrix formed at oocyte maturation initial stage and follicular development initial stage, and it comprises the albumen of three kinds of high glycosylations, is called as ZP1, ZP2 or ZP3.Described ZP plays an important role in fertilization process, because interact being first between the Mammals gamete caused by combining of the special acceptor on sperm and the ZP.In mouse, ZP3 glycoprotein has been proved to be the sperm-receptor (it is summarized referring to Wasserman, Development 108:1-17,1990) that is positioned at the complementary molecule in the sperm surface film.The above-mentioned ligand function of ZP3 can cause a kind of process that is called as acrosomal reaction, and the result of this reaction can discharge proteolytic enzyme, makes described sperm penetrate zona pellucida and makes oocyte fertilization by merging with the plasma membrane of ovocyte.
ZP3 glycoprotein in essence-ovum interacts vital role and the fact of ovocyte specifically expressing point out us, ZP albumen can be used as the ideal target antigen, is used to develop pregnancy vaccine (for example, Gwatkin etc., Fert.Ster.28:871-877,1977; Paterson and Aitken, Gurr.Opinion in Immunol., 2:743-747,1990).Confirm all that in a lot of researchs the zona pellucida protein of inoculating pig to Mammals can produce anti-used antigenic high antibody titer, and follows sterile.By in vitro study, also can obtain the result of the contraceptive effect of indication ZP3 immunity.Confirmed already that anti-ZP3 specific antibody can suppress microgamete with the combination of salt storage human oocyte (van Duin etc., Hum.Reprod.9 (Suppl.4): 41,1994), but also can destroy (Henderson etc., Gam.Res., 1988) in vitro fertilization of human body.
With natural ZP3 albumen is target antigen, and the vaccine for preparing based on ZP3 by engineering method is infeasible, because this biomaterial is very limited.Clone to coding ZP protein gene has solved the problems referred to above recently, produces reorganization ZP3 albumen or its segmental possibility thereby provide.The clone of described mouse ZP3 DNA and evaluation have constituted important step (Ringuette etc., Proc.Natl.Acad.Sci.USA 83:4341-4345,1986 of this purpose of marching toward; Rin-guette etc., Dev.Biol., 127:287-295,1988).The clone and the relevant proteic one-level aminoacid sequence of ZP3 of various Mammals ZP3 genes have been disclosed, as people ZP3 (WO 90/15624), hamster ZP3 (Kinloch etc., Dev.Biol., 142:414-421,1990), marmoset ZP3 (WO 94/10304), pig ZP3 (WO 93/14786), cat ZP3 (JP-A-06014784; WO 94,11019), dog ZP3 (JP-A-05336974; WO 94,11019), rabbit ZP3 (WO 94/11019), ox ZP3 (WO 94/11019) and macaque ZP3 (WO 94/11019).All illustrated so far Mammals ZP3 aminoacid sequences all show very high evolution conservative, and amino acid whose homology is in 65~90% scope.The conservative property of this proteic N-end of different mammalian species is relatively poor, and this shows that the specific specificity of proteic this part of ZP3 in the Mammals fertilization process has latent effect.
A lot of Mammalss with complete ZP3 protein immunization in most of the cases can both produce high anti-ZP3 and tire, and follow sterile.But, about also having mentioned the result of following unanimity in the report of above-mentioned research: the ovarian function that shows as the disorderly menstrual cycle is not normal, ovariopathy is of science and the forfeiture of the ovarian follicle of each etap, the forfeiture that comprises primordial follicle (for example, Skinner etc., Endocrinology, 115:2418-2432,1984; Upadhyay etc., Biol.Reprod.41:665-673,1989; Sehgal etc., Pathology 21:105-110,1989; Dunbar etc., Fert.Ster.52:311-318,1989; Jones etc., J.Reprod.Fert.95:513~525,1992; Mahi-Brown etc., J.Reprod.Immunol.21:29-46,1992; Paterson etc., Biol.Reprod.46:523-534,1992).This malfunction can cause permanent sterile.Especially concerning human body, this is a kind of side effect of very cakes with moulded designs, because only need be used for the control fertilization based on the immunological contraception effect of the vaccine of ZP3, therefore, the sterility of being brought out preferably can automatically or by the mode of operation recover normal.Therefore, complete ZP3 is not suitable for the safe contraceptive bian of exploitation.
ZP3 plays a part antigenic determinant, and it can bring out by T cell or B cell-mediated immune responses.Described antigenic determinant can be called t cell epitope or B cell epitope according to the bring out type of replying.With the mouse is model, has confirmed with viewed ovariopathy Neo-Confucianism behind the ZP protein immunization it is a kind of by the cell-mediated phenomenon of T.After carrying out immunity with a kind of 8 amino acid whose little t cell epitopes (the amino acid 330-337 that is equivalent to mouse ZP3), can bring out the ovariopathy Neo-Confucianism of mouse, be specially ovaritis.The T cell transfer of described animal can be caused the ovary damage equally in non-immune animal body, this result has supported that effectively t cell epitope is the view (Rhim etc. that cause the reason of ovary damage after the ZP3 immunity, J.Clin.Invest.89:28-35,1992; Luo etc., J.Clin.Invest.92:2117-2123,1993).
Therefore, in order suitably to prepare the pregnancy vaccine based on ZP3, press for the proteic fragment of ZP3, it does not contain the pathogenic T cell epitope of ZP3.An object of the present invention is to provide a kind of peptide, it is equivalent to the proteic single antigenic determinant of ZP3, and therefore, this antigenic determinant can not brought out by the cell-mediated pathogenic immunity of T and should be signed.
