Definitions
- the present invention relates to a preventive / therapeutic agent for granulomas, particularly granulomas occurring after ligation of vas deferens.
- sperm After vasectomy, a type of sterilization, sperm is thought to be processed by lysis and lysis in the epididymis and phagocytosis of macrophages. It is known that phagocytosis of macrophages is generally carried out via a scavenger receptor or the like expressed on the surface of cells of macrophages.
- an object of the present invention is to provide a novel preventive or therapeutic agent for granuloma, particularly sperm granuloma which occurs after ligation of vas deferens.
- the present inventor in particular, used a scavenger-receptor knockout mouse and a normal mouse in which the expression of a scavenger receptor was genetically manipulated, and ligated the vas deferens to these mice.
- Granules develop in knockout mice after administration
- the present invention was completed.
- the absence of sperm granuloma after vasectomy in a Schiavenger receptor knockout mouse indicates that sperm granulomas that occur after vasectomy can be prevented or treated by antagonist against the squamous receptor. The reason for this is to make it reasonably presumable.
- Ryoaki Moto provides a granuloma prophylactic / therapeutic agent using an agonist against the scavenger receptor of macrophages as an active ingredient, and particularly an antagonist against a scavenger receptor of macula phage as an active ingredient. It is intended to provide a preventive / therapeutic agent for sperm granuloma occurring after vasectomy.
- Examples of the antagonist to the scavenger receptor used in the present invention include antibodies against the scavenger receptor, such as monoclonal antibodies, chimeric antibodies, humanized antibodies and single-chain antibodies, and binding to the scavenger receptor. Fragments of the above antibodies that can be used.
- examples of the above-mentioned antagonists include antisense nucleic acids and low molecular weight compounds against nucleic acids encoding a scavenger receptor.
- Figure 1 shows a rough graph showing the time course of sperm counts in wild-type mice and scavenger receptor knockout mice after vasectomy.
- FIG. 2 is a daraf showing the time-dependent changes in testis weight in wild type mice and scavenger receptor knockout mice after vasectomy.
- the present inventors performed granulation after ligation of vaccinia in Schiavenger receptor mice and normal mice in which the expression of Schiavenger-receptor A (SR-A) was deleted by genetic manipulation. Observation of the tumor development revealed that, despite no substantial difference in sperm generation rate or testis weight between the two mice, granulomas developed in normal mice, and Schiavenger receptor knockout mice. They found that granuloma did not occur in the stomach, and that blocking of the scavenger receptor could prevent sperm granuloma after vasectomy.
- SR-A Schiavenger-receptor A
- Mactophage phage skibavenger receptor is a trimeric membrane glycoprotein with a molecular weight of about 22 OkD, extracellular C-terminal specific domain, collagen-like domain, Hi-helical coil Consisting of a coil domain and a spacer domain; a transmembrane domain; and a cytoplasmic domain (Kodama T. et al., Ature Vol 343, p.531-535 (1990); Matsumoto A. et al., Proc. Natl. Acad. Sci. USA 87: 9133-9137 (1990)) is expressed on the cell surface of macrophage cells.
- MSR-A Mactophage phage skibavenger receptor
- the isolated scavenger receptor particularly its extracellular domain, and genetic recombination, are required.
- the produced recombinant scavenger receptor protein particularly its extracellular domain, for example, a C-terminal specific domain, can be used as an immunogen.
- a polyclonal antibody against the Schiavenger receptor is used to immunize animals other than human, such as rabbits and goats, with the above-mentioned immunogen. It can be obtained from animal serum. Monoclonal antibodies can also be produced by methods well known in the art. For example, a laboratory animal such as a mouse is immunized with the above-mentioned immunogen, antibody-producing cells, for example, spleen cells are collected, and fused with a myeloma cell line, for example, SP20, to obtain a target monoclonal antibody. It is possible to obtain a hybridoma producing a lonal antibody.
- the humanized antibody is used to determine the complementarity-determining regions (CDRs) in the variable regions (V regions) of the heavy (H chain) and light (L chain) chains of the human antibody, and to determine the complementarity-determining regions (CDR) in mice other than human. It has been replaced with the corresponding CDR of an animal monoclonal antibody.
- the constant region (C region) and the framework region (FR) in the V region are derived from a human antibody, and only the CDR is a non-human monoclonal antibody. It has the advantage of having very low immunogenicity in humans because it is derived from a primary antibody. '
- Methods for producing humanized antibodies are well known. For example, by cloning cDNA encoding the V regions of the H chain and L chain of a mouse monoclonal antibody against the Schiavenger monoreceptor, Determine the acid sequence, distinguish between ⁇ 01 and 1, select the V region of the human monoclonal antibody that has high homology to the amino acid sequence of the mouse FR region, and select the cDNA encoding the V region.
- the CDR coding region is replaced with the CDR coding region of a mouse monoclonal antibody by a well-known gene recombination method, and a vector containing the H chain coding sequence thus prepared and an L chain coding sequence are prepared. Is expressed in a host animal cell, and the resulting H-chain protein and L-chain protein are allowed to assemble.
- the chimeric antibody is obtained by linking the C region of a human monoclonal antibody and the V region of a non-human animal monoclonal antibody with respect to the H chain and the L chain, respectively.
- the V region of the mouse monoclonal antibody to the receptor receptor may be linked to the C region of any human antibody.
- Methods for producing chimeric antibodies are also well known in the art.For example, a DNA fragment encoding a V region is cloned from DNA encoding a mouse monoclonal antibody against a scavenger receptor, and the resulting fragment is isolated from a human antibody.
- an expression vector is prepared for each of the H chain and the L chain, and these are expressed in host cells, and the resulting chimeric H chain protein and chimeric L chain are produced. You just need to assemble the protein.
- Single-chain antibodies include, for example, the H chain V region and L chain V of a monoclonal antibody such as a mouse, a humanized monoclonal antibody, or a chimeric antibody against the scavenger receptor as described above.
- the region is linked to the region via an appropriate spacer.
- Methods for producing single-chain antibodies are also well known.For example, DNAs encoding the V regions of the H chain and L chain of the above-mentioned monoclonal antibody, chimeric antibody or humanized antibody are obtained, and these are used as linkers. It may be ligated via the DNA to be coded, and the expression vector containing the gene may be introduced into an animal host cell for expression.
- an antisense nucleic acid against a nucleic acid encoding this scavenger receptor may be used.
- the gene encoding the human macrophage scavenger receptor has been cloned (Matsumoto. A. Proc. Natl. Aced Sci. USA 87:91 33-9137 (1990)).
- Complementary nucleic acids can be used as antisense nucleic acids.
- Antagonists of the present invention may also be low molecular weight compounds.
- scavenger receptor antagonists include, for example, For example, polyvinyl sulfate (polyvinyl sulfate), polyinosinic acid Lysanthininoleic acid, polyxanthinylic acid, polyguanylic acid, poly G, I (l: l) (poly G, 1 (1: 1)), dextran sulfate, fucoidin (f ucoidin), carragheenan, bovin e sulfatides, malaylatecl LDL (malelatecl LDL), maleylated albumin, and maleylated albumin.
- Antagonists for macrophage scavenger receptors that can be used in the present invention are described, for example, in PCT publications W02000006147, W02000003704, W09907382, JP-A-11-246512, JP-A-11-246511, J. Pharmacol.Exp.Ther. (1999), 289 (3), 1277-1285, ⁇ .S. Brow ⁇ , S. ⁇ .Basu, JR Falck, YKHo, and J.L Goldstein
- the Scavenger Cell Pathway for Lipoprotein Degradation Specificity of the Binding Site That Mediates the Uptake of Negatively-Charged LDL by Macrophages, Journal of Supramolecular Structure, Vol. 13, 67-81 (1980).
- the prophylactic / therapeutic agent of the present invention can be administered orally or parenterally, and the antibody is preferably administered by injection, for example, intravenous injection.
- the antibody is preferably administered by injection, for example, intravenous injection.
- Knockout mice (Suzuki H. et al., Nature, Vol. 386, pp. 292-296 (1997)) and wild-type mice were purified from pentoparbital sodium (Suzuki H. et al.). (Nembutal, Abbot La boratories, USA). A small vertical midline abdominal incision was made. Each vas deferens was ligated twice with 5-zero silk (Matsuda Sutures, Tokyo).

- FA / 11 Monoclonal antibody against murine macroline (CD68) (Holness CD et al., J. Biol. Chem., Vol. 30, p. 9661-9666 (1993)).
- the testes weight and the number of sperm production per day were not substantially different between the knockout mice and the wild-type mice.
- the number of sperm production per day was significantly reduced two weeks after the operation, but returned to the value of the non-operated control mice four weeks after the operation.
- the value of sperm production per day two weeks after surgery in knockout mice was not significantly different from the number of sperm production per day two weeks after surgery in wild-type mice. .
- mice In wild-type mice, during the observation period, about half of the operated mice had granuloma. The granulomas were mainly located in the epididymis of the wild-type mouse (corpus ep ididymi s) and in the epididymis tail (cauda epididym is). However, none of the 17 SR-A knockout mice that had undergone surgery produced sperm granulomas (Table 1).
- Table 2 shows the expression of the scavenger receptor antigen in the epididymis head, body and tail as well as in the epididymis granulomas of wild type mice. Basal cells in the epididymis head, body, and tail were positive for F4 / 80 but negative for 2F8. S The RA antigen was expressed on macophage phage in stromal tissue in all parts of the epididymis.
