Definitions
- the present invention relates to peptides or derivatives thereof.
- the peptide of the present invention or a derivative thereof is useful not only for the treatment of non-antigen-specific suppression of an abnormally enhanced immune response in an autoimmune disease, but also a peptide or a derivative thereof of the present invention has an anti-inflammatory effect. It is also useful for treating inflammation.
- the present invention relates to the field of peptides and derivatives thereof, and the field of medicine using the same.
- Sun and moon
- An autoimmune disease is a disease caused by the continuous production of antibodies or lymphocytes that react with the constituents of the own tissue. More specifically, autoimmune diseases result in the breakdown of immunological tolerance, resulting in an increase in the immune response to their own biological components, and the generated autoantibodies or autoreactive ⁇ cells react with the corresponding autoantigens and cells. It is a disease that causes abnormal cell function and tissue damage. Currently, more than 50 types of autoimmune diseases are known, and they are classified into organ-specific autoimmune diseases and non-organ-specific autoimmune diseases according to the spread of affected organs.
- Examples of the former include insulin-dependent diabetes mellitus whose lesions are caused by the selective destruction of B cells in the islets of Langerhans; There are myasthenia gravis, in which antibodies against striated acetylcholine receptor pigs decrease muscle contraction, and autoimmune hemolytic anemia, in which antibodies against erythrocytes cause hemolysis of erythrocytes.
- Examples of the latter include rheumatoid arthritis, DNA and DNA, which are thought to cause the aggregation of IgG and anti-IgG antibodies (rheumatic factors) to trigger bone and cartilage tissue throughout the body.
- Antibodies against nucleus components are sensible, impaired reactions appear by depositing on joints and skin moes, etc.Function by infiltration of lymphocytes into systemic erythematosus, salivary glands, lacrimal glands, etc.
- Siegren's syndrome which causes insufficiency and, more frequently, systemic organ involvement such as interstitial nephritis; diffuse demyelinating foci and gliosis in the white matter of the central nervous system; There are multiple sclerosis with paralysis, eye symptoms, paresthesia, etc.
- T cells recognize the antigen itself during the reaction with the antigen
- T cells recognize the combination of the MHC molecule on the surface of the antigen-presenting cell and the antigen peptide contained in the groove.
- MHC molecules vary from individual to individual, and human T cells with MHC that are compatible with an antigen respond well to that antigen. This is partly because certain humans are more susceptible to specific antigens.
- the antigen receptor of T cells T ⁇ antigen receptor, T cell receptor: T c R
- the T cells bind to several go to the one without There are substances that activate it and are called superantigens.
- Superantigens activate larger amounts of T cells than normal immune responses, which can cause a large response and cause disease.
- T cells Activation of T cells requires not only antigen recognition but also the binding of a partner molecule (ligand) to surface adhesion molecules. Therefore, blocking the adhesion molecule can block the T cell response, and increasing the expression of the partner cell's ligand can amplify the reaction.
- ligand partner molecule
- T cells that suppress the immune response so-called suppressed T cells
- suppressed T cells exist in the T cell group
- T cells have been shown to produce soluble immunosuppressive factors that suppress antibody production in an antigen-specific manner (Tada, et al., J. Immnul., Vol. Ill, p952, 1973).
- TcR alpha chain has been reported (Dorf, et al., J. Immunol., Vol. 145, pp 2809-2819, 1990).
- mice a model of multiple sclerosis EAE
- TcR T cell antigen receptor
- a treatment method using an antibody against a disease-specific TcR or a TcR peptide vaccine was developed (Howell, et al., Science, vol. 251, p P430-432, 1991; Vandenbrk, et al.). , Nature, vol.341, pp541-544, 1989).
- TcR peptide fragment of T cells is administered to suppress the onset of EAE (WO 9 0/1 1 2 9 4) is disclosed.
- Mohapatra and colleagues also demonstrated that a synthetic peptide consisting of a 15-residue amino acid containing CDR3 (Complementarity Determining Region), which is a specific antigen recognition site for T cell-derived TcR, is immunosuppressive. It has been shown to have an effect (J. Immunol., Vol. 151, pp. 688-98, 1993).
- An object of the present invention is to overcome the disadvantages or drawbacks of the conventional method as described above and to have an antigen-specific immunosuppressive effect that can be used for the treatment of autoimmune diseases whose antigens have not been elucidated.
- An object of the present invention is to provide a therapeutic agent for an autoimmune disease.
- Another object of the present invention is to provide a therapeutic agent for an autoimmune disease, which can be used for treating an autoimmune disease accompanied by inflammation.
- the object of the present invention is that it is a low-molecular peptide as compared with the conventional method, the peptide can be produced at low cost, and the side effects such as the occurrence of antigenicity in frequent administration are greatly reduced. And derivatives thereof.
- the present inventors have been diligently examining the correlation between proteins such as CDR3 of TcR derived from suppressed T cells and amino acid sequences such as peptide fragments thereof and therapeutic agents for autoimmune diseases. It has been found that some peptides have an IgG non-specific inhibitory activity nonspecifically.
- the present inventors have found that the peptide consisting of 9 amino acids of amino acid shown in SEQ ID NO: 1 in the sequence listing can be used not only to produce anti-ovalbumin (Ovalbumin: ⁇ VA) antibody but also to produce anti-keyhole limpet.
- the inventors have also found that the production of Keyhole Lympet Hemocyanin (KLH)) antibody is also suppressed in vivo, and thus completed the present invention.
- KLH Keyhole Lympet Hemocyanin
- 0 VA and KLH are typical antigens used as immunizing antigens (Immunology Encyclopedia, 1993, Tokyo Kagaku Dojin, p. 101 and p. 130).
- the TcRs of suppressor T cells specifically correspond one-to-one to a variety of antigens.
- the peptide of the present invention has an immunosuppressive activity characterized by being non-antigen-specific by suppressing the production of antibodies against different antigens such as OVA and KLH.
- the peptide consisting of the 9-amino acid amino acid shown in SEQ ID NO: 1 in the Sequence Listing is an experimental cerebrospinal cord that is a model of multiple sclerosis, which is one of the autoimmune diseases involving T cells.
- a peptide consisting of the 9 amino acid residues shown in SEQ ID NO: 1 suppresses edema and has an anti-inflammatory effect in a carrageenan-induced paw edema model. I also found this.
- the peptide of the present invention suppresses the activity of T cells and has an immunosuppressive activity having an anti-inflammatory effect.
- the present inventors have worked diligently to develop low-molecular-weight peptides that are less antigenic and easy to synthesize, and have obtained the 8-residue amino acid shown in SEQ ID NO: 2 in the sequence listing. Consisting of anti-KLH suppresses not only anti-VA antibody production but also anti-KLH production in vivo I found this. In addition, the present inventors have determined that, among peptides having a certain universal amino acid sequence, those having IgG-inhibitory activity in a non-antigen-specific manner can be determined by the alanine substitution method ( Geysen HM, et al., (1987), J. Immunol, methods, 102; 259-274).
- the present inventors have found that peptides having these universal amino acid residues can produce anti-ovalbumin (OVA) as well as anti-keyhole limpet hemocyanin (KLH) antibody antibodies. Were also found to be suppressed in vivo, and the present invention was completed.
- OVA anti-ovalbumin
