DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of immunology, including the development of immune tolerance and the pathology of autoimmune diseases. The present invention also relates to an improved method for identifying an organ-specific autoimmune disease ' myasthenia gravis. [Prior Art] An autoimmune disease is an immune cell that is abnormal in function or activity, causing inappropriate activation of T cells, causing T cells to attack their own tissues, thereby promoting the production of cytokines and/or autoantibodies. 'Causes disease development and disease progression (Cotran et al., Pathologic basis of disease 21 l-212 (6th ed. 1999); Scofied, "Autoantibodies as predictors of disease," 363: 1544-1546 (2004)) ° Autologous Immune system refers to the loss of autologous tolerance, but the mechanism is still unclear. Autoimmune diseases can be classified as systemic and affect multiple organs or tissues; or local, affecting only a single organ, organ system or tissue. The main feature of autoimmune diseases is the production of high-affinity autoantibodies against autologous proteins (Robinson et al., 6t Autoantigen microarrays for multiples characterization of autoantibody responses,,, Nature Med. 8(3): 295 -301 (2002)). It is currently known or suspected that certain autoantibodies are involved in the destruction of cells or tissues of a particular disease, but in general, the relationship between pathogenicity and the underlying cause of the disease remains unknown. However, autoantibodies are specific to the disease. * 1357979 The specific pathogenicity of diseases such as myasthenia gravis indicates that it can be used to improve diagnosis, classification and treatment of autoimmune diseases. Because it usually occurs in the symptoms of the disease. The autoantibodies in the serum have existed for a long time. Therefore, if the autoantibodies related to specific autoimmune diseases can be detected quickly and accurately, they will be given before the onset of the disease. Prophylactic treatment 'even completely prevents the occurrence of autoimmune diseases. Myasthenia gravis (MG) is a neuromuscular disorder. This is due to the loss of acetylcholine receptors in neuromuscular junctions due to immune dysfunction (Cotran et al., Μ Μ; ? " α (1289)). It is estimated that every 3 〇〇 people in the world have about 3 to more than 20 people with myasthenia gravis (Cotran et al., supra·, Somnier, ^Increasing incidence of late-onset anti-AChR antibody-seropositive Myasthenia gravis, 5, Neurol, 65: 928-930 (2005)). In the United States, about 14 people are estimated to have myasthenia gravis, and about 36,000 cases are diagnosed each year. • There is myasthenia gravis (Howard, “Myasthenia gravis: a summary ," available at http://www.myasthenia.org/information/summary.htm, last accessed October 23, 2005). Early onset myasthenia gravis is defined as occurring in women before 40 or 50 years of age, and late onset myasthenia gravis is the same in both men and women (Cotran) Et al., (noting that MG is most commonly observed in women "when emergence before age 40 years'')); Somnier, supra (4tthe 7 1357979 dichotomy between early-and late-onset MG was defined at age 50") . Women's disease progression usually occurs between about 20 and 40 years of age, while men occur between about 50 and 60 years of age, although sometimes it happens earlier, but at the same time, both sexes usually occur later. (Cotran et al., swpra) Clinically, about two-thirds of patients with myasthenia gravis have first symptoms of occasional muscle weakness, most of which occur in extraocular muscles. On (Howard, this early symptom will be severe to the eyelid drooping and / or diplopia, and therefore resort to drug treatment. About 10% of myasthenia gravis patients with muscle weakness is Luma limited to the eye muscle (ocular muscle) (Howard, sen; 7 〇〇. In the later stages, many patients will develop symptoms of frequent muscle weakness such as weekly, daily or more frequent. General myasthenia gravis affects muscles, such as facial Control, chew, talk, swallow, and breath; often lead to death from respiratory failure before new treatments. More than 95% of patients will survive for about 5 years after diagnosis and improved care. Or more time. About 65% of patients with myasthenia gravis will be accompanied by thymic hyperplasia, and about 15% of patients will be accompanied by thymoma. Patients with myasthenia gravis need to use cholinesterase inhibitors and intensive care for a long time. These treatments can directly reduce or slow down the autoimmune response, or change their response to acetylcholine receptors. Effects, and the ability to maintain peripheral nerve-muscle junctions for a long time ("Treatment of autoiummune myasthenia gravis,''A^wro/.61:1652-1661 (2003)). Patients with myasthenia gravis pass 8 1357979 often An anti-acetylcholinesterase agent, such as an acetylcholinesterase inhibitor, is generally treated with high doses of corticosteroids to reduce the immune response, often accompanied by intravenous immunoglobulin or plasma. Plasmapheresis. After alleviating the immune response, the dose of cortisol can be gradually reduced, and a steroid-sparing agent such as sulfur "azathioprine" or mycophenolate can be used in combination. Etc. In some cases, thymectomy can also be used for treatment. About 80-85% of patients with myasthenia gravis are directly attacking themselves with autoantibodies. The nicotinic acetylcholine receptor (AChR) is characterized (Richman et al., supra; Roxanis et al., "Thymic myoid cells and germinal center formation in myasthenia gravis; possible roles in pathogenesis," J. TVewro /mwwwi?/· 125:185-197 (2002)). These autoantibodies destroy the acetylcholine receptor and reduce the function of the muscle end-plate of the mature neuromuscular junction, which will lead to the destruction of neuromuscular signal transmission and the general myasthenia gravis. Symptoms of muscle weakness (Hoch et al., "Auto-antibodies to the receptor tyrosine kinase MsSK in patients with myasthenia gravis without acetylcholine receptor antibodies," 7(3): 365-368 (2001)). In patients with similar degrees of disease, the anti-AChR serum antibody varies widely, so it cannot be used to predict the severity of each patient (Howards, swpra) ° and not every myasthenia gravis A patient with anti-AChR 9 13357979 antibody (anti-AChR) (Roxanis et al., • swprfl). In some cases, the presence of anti-AChR antibodies cannot be detected until several months or more after onset. If general MG and ocular MG are used, 'anti-AChR antibodies are more common in patients with general myasthenia gravis: about 74% of patients with general myasthenia gravis can detect Anti-AChR antibodies, and 54% of patients with ocular myasthenia gravis can detect anti-AChR antibodies (Howard, swpra). And about 10-20% of patients with general myasthenia gravis cannot detect the presence of anti-AChR antibodies, and about 90% of these anti-AChR antibodies have identifiable muscle receptors. Autoantibody of muscle-specific receptor tyrosine kinase (Musta) (Hoch et al., swpra; Roxanis et al., sin; ^). At the onset of synapses, MuSK promotes the accumulation of AChRs by citrulline and is expressed in the thermogenic neuromuscular junction (Hoch et al., ϊΐφΓβ). Therefore, there is still a need for a better method for detecting severe ailments. SUMMARY OF THE INVENTION The present invention provides a method for detecting neuromuscular autoimmune disease myasthenia gravis (MG). At least a part of the present invention is based on the discovery of autoantibodies of heat shock protein 6 (hsP60) and heat shock protein 90 (HSP90) in patients with myasthenia gravis at the initial stage, and the above two proteins are not It is mentioned in the etiology and pathological development of previous myasthenia gravis.

For example, the prior literature and commonly used techniques are to select suitable keys. The above conditions are usually set to an antibody concentration, ionic strength in solution, temperature, bonding time, concentration of molecules that are not directly acting (such as blocking agents, such as serum proteins, bovine cheese protein), etc. (Morgan et al "The Matrix Effects on Kinetic Rate Constants of Antibody-Antigen interactions Reflects Solvent Viscosity, J. /mwwwo/.

Detection of Autoantibodies And quantitative methods The amount of antibodies to detect autologous. 1357979 * * set of methods for the presence or absence of specific autologous antibodies simple detection in biological samples. The quantitative method calculates the concentration of autoantibodies in addition to whether a specific autologous antibody is present in the biological sample. The above qualitative and quantitative methods are all known techniques. For example, Western blotting, immunoblotting, immunofluorescence, enzyme-linked immunosorbent assay (ELISA), and other comparable techniques. 1. Western ink point method Western ink point method is first an electrophoresis step, which uses polyacrylamide gel, according to the size and charge of the protein, separates the protein of interest and breaks the protein to On a charged film. After the transversion/bein element is completed, the hybridization procedure is started. The unreacted bonding position on the membrane is filled in a blocking step to avoid non-specific adsorption of the antibody, and then the antibody is added once with one or more The target antigen is bonded, and finally the secondary antibody is added. After an appropriate time reaction, the antigen-antibody complex formed therein is radiant, chromophoric, or chemically colored. The substance (chemiluminescem means) is detected. Secondary antibodies typically uniquely recognize the constant regions (Fc) of all immunoglobulins of the same type. Secondary antibodies can be derived from a variety of mammals, including rabbits, sheep, goats, mice, and rats, but are not necessarily limited to the above. Animals. In order to detect the amount of autoantibodies that can uniquely identify the characteristic autoantigen of mg by Western blotting, one or more of the characteristic autoantigens of myasthenia gravis will be purified or recombined. Techniques were carried out on sodium dodecyl sulfonate-polypropylene guanamine colloidal electrophoresis (SDS-PAGE) (see Sambrook 15 1357979 et aL, 3Molecular cloning: A laboratory manual A8.40-A8.45 (2001)) (introduction of many proteins) Colloidal electrophoresis reagents and methods) after 'crushing the protein in the colloid to nitrocellulose (nitr〇cellul〇se), nylon (nylon), fluorinated ethylene ethylene (PVDF), or suitable for general fixed and western ink Other membranes or filter papers of the dot method, the above-mentioned fixed and western ink dot method standards are the same as the conventional techniques. The above-described tumbling method may be a wet immersion or a semi-dry tumbling method, and may be other conventional techniques. In addition, one or more of the autoantigens may be present in other membranes such as nitrocellulose, nylon, fluorinated fluoroethylene (pvDF) or other suitable for stationary and western inks. Point on other membranes or filter paper. If a target autoantigen is purified or recombined, standard methods can also be used to obtain autoantigens from lysates or milled tissues. The protein is then immobilized on a membrane or filter paper to avoid loss of the target protein during multiple hybridization, washing, and staining steps following subsequent Western blotting. The method of solidification can be achieved by 'hot_linking with ultraviolet light' or other conventional methods (refer to Sambrook et al., 3 Molecular cloning: A laboratory manual A8.52-A8.55 (introduction of many immunizations) Ink dots and methods for detecting antigen/antibody complexes)). And a buffer solution (such as phosphate buffer (phosphate_buffer * sa 1 me, PBS) and other similar solutions) to block the fixed membrane or filter paper. Non-specific antibody binding position, the above buffer solution contains a seal Resistors, such as 0.5% (w/v) low-fat milk powder or 5% (w/v) bovine serum albumin (BSA). After blocking, the antibody is added to react with the membrane or filter paper, and in the present invention, it is reacted with a biological sample taken from an individual diagnosed as an autoimmune disorder. 16 1357979 After the reaction with the primary antibody is completed, the membrane or filter paper is washed, and the autoantibody/autoantigen complex is identified by a secondary antibody, which is labeled with a chromogenic substance and a fluorescent substance. (fluorogenic) or chemical. Chemiluminescent means. The autoantibody/autoantigen complex described above can be detected by a colorimetric method such as horseradish peroxidase and TMB or an automatic radiography such as an immunolase. If colorimetric or chemical chilling is used, the amount of this color or fluorescence can be measured by luminescence {liminometer, spectrophotometer* or other similar instrument. In the case of automatic radiography, the amount of antibody binding can be known by optical density or other similar instrumentation exposure X-rays (see Sambrook et al., 3Molecular Cloning: A laboratory manual A8.52-A8.5). 5 (introducing many methods of immunizing ink dots and detecting antigen/antibody complexes)). Secondary antibodies can be used for qualitative or quantitative analysis, which can be single or multiple antibodies, and a ligand (such as φ biotin) or a detectable marker can be labeled on a secondary antibody by conventional techniques. (such as fluorescent or enzyme). Suitable labels include fluorophores, chromophores, electron-dense reagents (such as gold or silver), enzymes, and ligands that are specifically bonded to other substances. Enzymes such as wasabi peroxidase or alkaline phosphatase are usually tested for activity. For example, wasabi peroxidase converts tetradecylamine (TMB) to blue and quantified by spectrophotometry. Other suitable ligands and/or detectable markers include biotin, avidin, or streptavidin, IgG, protein A, and a number of additional receptor-coordinator combinations known. Other possibilities and advantages of the prior art are all obvious and are all aspects of the invention. In a consistent example, Western blotting is used to detect at least one autoantibody bound to an autoantigen antigen. The above autoantigen is specific and linked to the following proteins: heat shock Protein 60 (HSP 60), heat shock protein 90 alpha (HSP90o, or heat shock protein 90 beta (HSP90p). In standard Western blotting steps, such as far western blots' and others There are various variations in the quantitative dot method. Those skilled in the art can rely on the source of the autoantibody, the autoantigen, the autoantigen and/or the primary autoantibody used, and any other experimentally relevant parameters. Selecting suitable methods. Other substitutions and possibilities by conventional techniques are obvious and are one of the forms of the invention. 2. Enzyme-linked immunosorbent assay (ELISA) Some enzyme-linked immunosorbent assays are used for qualitative analysis. It can be easily analyzed for specific antigens or antibodies, but the enzyme-linked immunosorbent assay can also be used to quantitatively calculate the antigen or antibody concentration accurately because it can be easily and automatically read. Therefore, enzyme-linked immunosorbent assays are commonly used to screen a large number of specific binding-specific antigens or antibodies. Enzyme-linked immunosorbent assay is initially an antigen-coating step, and one or more target antigens are adsorbed to a microtiter plate. In the hole (see Kirkegaard & Perry laboratories, Inc., Technical Guide for ELISA 9-13 (2003), available at http://www.kpl. com/home.cfm# (last accessed November 3, 2005) ( Introduce various microtiter plates of ELISA and various methods and reagents for coating proteins in pores. General adsorption buffers commonly used for antigens 1357979 include 50 mM carbonate, ΡΗ=9·6; 10 mM Tris-HCl, pH =9.6; ι〇mMPBS, pH=7, 2. The above buffer is suitable for many proteins. If one or more of the above antigens cannot be adsorbed on the pore surface of the microtiter plate, a commercially available microtiter plate can also be used. The surface is repaired, and various chemical methods can be used to bond proteins to the surface by covalent bonding. Time and temperature are important in the adsorption process of proteins. Impact factor. After coating the target antigen on the microtiter plate, wash the microtiter plate with blocking buffer to remove non-specific bond and reduce the occurrence of false positives. 13-13) (Introduction of blocking method and reagent The commonly used blocking reagents are not protein solutions, such as BSA (between about 1% to 5% (w/v) in PBS, pH=7.0), skim milk powder, casein (main protein of skim milk powder) ) is cool casein (higher solubility protein, partial cut with sodium hydroxide), general serum (concentration between about 1% and 5% (v/v)) and Gelatin (concentration between about 1% and 5% (w/v)) or ion-free detergents such as Tween-20TM and Triton X-100TM. Buffers that do not affect the interaction of low affinity between the various reaction components are generally selected as the wash buffer, as each reaction component affects the ability to detect specific antigen-antibody effects (zW. at 14- 15 (Introducing various methods and reagents for cleaning microtiter plates)). The cleaning solution usually has a physiological buffer to avoid denaturation of the antigen and the antibody, and maintains the activity of the enzyme. Buffers of the same natural pH as natural physiology, such as PBS, Tris-saline, imidazole-buffered saline, and the like, are often used. In a specific analytical experiment, the specific buffer should be selected according to the method 17 1357979 of the specific detection test. At the same time, the cleaning buffer should also contain non-ionic detergents such as Tween-20 TM and Triton X-100TM at concentrations ranging from 〇! 0/〇 to 0·05〇/〇(ν/ν). Avoid low-affinity and non-specific bonding between the reaction components. After the blocking procedure, the pores of the microtiter plate are washed, and the primary antibody is added to react with the antigen adsorbed to the pore. The primary antibody of the present invention is a biological sample taken from an individual diagnosed as an autoimmune disorder. After the primary antibody is completed, the pores are cleaned and a secondary anti-calling body marked with a coloring substance (such as wasabi peroxidase and hydrazine), a fluorescent substance or a chemically luminescent substance (such as alkaline phosphatase) is detected. Body antigen-autoantibody complex (W at 15-21 (introducing the preparation and use of antibodies, and commonly used in detecting substances. Finally using luminometers, spectrophotometers, etc.) The instrument counts the amount of color and fluorescence. Standard enzyme immunoassay methods have various variants, such as competitive ELISA, sandwich ELISA, etc. Familiar with the antibodies, antigens, antigens and/or once used by those skilled in the art. Appropriate methods are selected for the source of the antibody and experimentally relevant parameters. Other substitutions and possibilities by conventional techniques are obvious and are one of the forms of the invention. B. Clinical myasthenia gravis ·

Rev. Genet. 27:437-496(1993))。在逆境耐受性中,各種不同的熱休克 蛋白在保護生物體上扮演著不同角色。 a.熱休克蛋白 60(The 60 kD Heat-Shock Protein) 熱休克蛋白60(HSP60)首先發現於粒線體基質,上述蛋 白佔粒線體基質所有蛋白質的l%(Parsell et al., swpra at 465)。人類HSP60(胺基酸序列:1)與大腸桿菌的GroEL在 24 1357979 胺基酸序列上約有60%相同。且上述二種蛋白質有相同的 寡聚體結構(oligomeric structure),可構成一 7元環 (seven-membered ring),有時則可形成雙7元環(two seven-membered rings)的雙環(double doughnut)結構。在溫 度上升時,HSP60的表現量會增加,且其具有ATPase的 功能,與HSP60鍵結的ATP寡聚體上做一適當的結構改變。 HSP60不同於其他的熱休克蛋白,其在正常的溫度 下’同樣也具有功能(/d at 465-66),且可在所有的溫度中 表現。HSP60與未摺疊或變性的蛋白質有高度的親和性, 可促使它們進行適當的摺疊。蛋白質在與HSP60鍵結後, 變性的結構可轉變為二級結構,並抑制其他複合體的產生。 b.熱休克蛋白 90(The 90 kD Heat-Shock Proetin) 熱休克蛋白90(shp90)彳艮早就發現存在於真核生物的細 胞質及細胞核中,但在無胞器的生物上仍未發現(parsell et al” swrpa at 470)。HSP90在細胞質中具有二種同型結構 (isoform) ’分別為HSP90ct,受誘導表現,主要結構(序列 辨識號:2)及HSP90p ’可持續性表現,次要結構(序列辨 識號·· 3)(Sreedhar et al.,“HSP90 isoform: functions, expression and clinical importance,,, FEBS Letters 56.2:11-1.5(2004))。現階段難以生化的方式來分辨α型及β 型,且目前皆是使用二者的混合來進行H S Ρ 9 〇的相關研究。 人類的HSP90a與大腸桿菌的HtpG在胺基酸序列上有 約40%相同(parsell,仰;να·)。HtpG在正常溫度時可維持一 定的濃度’而在高溫時可被大量誘導產生,但其並不是生 25 1357979 物所必需的蛋白質,因在將其基因移除後,並不會影響大 腸桿菌在正常溫度的生長,且只稍微影響其在高溫的生 長。相較之下,HSP90是真核細胞中眾多蛋白質的其中之 一 ’在非逆境時,其佔所有細胞蛋白質的1_2%。若將真核 生物的HSP90基因移除,會導致生物體的死亡,表示真核 的HSP90具有原核生物所不具有的一新功能(Sreedhar et al·,—ra; Parsell et al.,似;。 HSP90可與細胞中許多的蛋白質反應,包括酪蛋白激 酶Π (casein kinase Π )、受血紅素控制之eIF-2a填酸酶 (heme-regulated eIF-2a kinase)及固醇類荷爾蒙受體如雌激 素(estrogen)、黃體素(progesterone)、雄性素(androgen)、糖 皮質類固醇(glucocorticoid)、戴奥辛(dioxin)受體,src族的 致癌路胺酸激酵素(oncogenic tyrosine kinases of the src family)、鈣調理素(calmodulin)、肌動蛋白(actin)及微管蛋 白(加1)111111)等(?&犷56116{已1.,抓;?^3&1471)。經由實驗發現, 在細胞的分化及發育上’ HSP90扮演多功能的角色,如調 控肌肉發育、早期胚胎發育至計畫性細胞死亡(programmed cell death)或細胞凋亡(apoptosis)(Sreedhar et al., supra,at 12)。此外’也已證實HSP90會在複數種的腫瘤中表現,如 胰臟癌、乳癌及血癌(M at 13)等。且其中HSP9〇p轉錄的 能力在紅斑性狼瘡患者中較高,而紅斑性狼瘡為一種自體 免疫疾病,其原因為自體抗體攻擊自身的剪接體snRNA, Ro/La 核醣體粒(Ro/La ribonuclear particle),組蛋白及 (histone)及/或自然的DNA等。 26 1357979 n '&測自體免疫的檢測套組 本發明之檢測方法可由一檢測套組來完成,上述檢測 • 套組包括一或複數種上述偵測自體抗體的技術,上述自體 抗體係專一性的與至少一種重症肌無力症的自體抗原鍵 結°在一實施例中,上述套組以西方墨點法分析上述自體 抗體。上述套組包括複數個測試工具,其中包含混合本發 明新發現之二種自體抗HSP60及HSP90a/HSP90p。 在—實施例中’上述檢測套組更包括專一於每個自體 •抗原的對照抗體(control antibodies),二次抗體.以直接或間 接的方式與山葵過氧化酶或任何試劑結合,上述試劑可呈 現自體^原-自體抗體複合體,且上述套組包括西方墨點法 封阻’月洗、雜合及偵測等過程中所有需要的試管、容器 或反應器、緩衝液及試劑。上述對照抗體可以緩衝液、溶 劑或乾燥粉末等形式來提供。若對照抗體為緩衝液或溶劑 的^式’則可預先混合,但若為粉末的形式,則必須在使 用則加人溶液回溶。此外’檢測套組還包括其它成份 裝、說明書或可幫助翻自體抗體的物質。 在另貫施例中,上述套組可以ELISA來價測自體抗 體本發明t形態係為上述套組,包括複數個微量滴定 -盤’包覆有本發明新發現的二種新自體抗原聊6 HSP90a/HSP90p 〇 在-實施例巾’上述套組更包括各自體抗原的對照抗 ,(control antibodies) ’二次抗體以直接或間接的方式與山 葵過氧化酶或任何習知試劑結合.,上述試劑可呈現自體抗 27 1357979 • . t自體複合體,且上述套組包括ELISA中封阻、清 經财^價測等過程所有所需的試管、容器或反應器、 太^T。上述對照抗體可以緩衝液、溶劑或乾燥粉 乂來h供。若對照抗體為緩衝液或溶劑形式,則可 $先混合,但若為粉未形式,則必須在使用前加入溶液回 /谷此外,檢測套組還包括其它的成份、包裝、說明書或 可幫助偵測自體抗體的物質。 〆 實施例 實施例1 :以西方墨點法偵測自體抗體 血清樣本取自中華民國台灣新光醫院中209位重症肌 無力症患者。可將這些患者依其胸腺的病理分為四大類: 其中37位病人有不同程度的胸腺萎縮(thymic atr〇phy); 121 位的病人發展成胸腺瘤(thymoma) ; 40位病人有不同程度 的胸腺增生(thymic hyperplasia);及11位病人的胸腺有未 知病變。此外,76位病人為笫I型MG,81位為第na型 MG ’ 38位為第nb型MG,14位為第皿或第IV型MG。陰 性對照組(negative control)的血清樣本為來自台中榮民總 醫院的54位患者,他們為另一種自體免疫疾病的膜狀腎 絲球腎炎(Membranous glomerulonephritis, MGN)病人。 將HepG2/C3A細胞溶胞產物以10%的SDS-PAGE膠體 分離,其每條泳道給予Kg的細胞萃取物及而在驗證 HSP60或HSP90蛋白的每條泳道則是給予2 pg蛋白。電 泳過程中,樣本在焦集膠體時給予80 V的電壓’而進行至 在分離膠體時給予120 V的電壓。分離的蛋白質可利用 28 1357979 • · TE70系列半乾式轉潰單位轉潰器(TE70 Series Semi-dry Transfer Unit)(Amersham Bioscience)轉潰到 PVDF 膜上。所The method of the antigen, including A US-2005/0124076-A1 ^ v is described in the U.S. Patent Publication No. This patent is incorporated into the present application, the method of the present invention, and the self-dissociation (4) & Methods from healthy individuals. The serum samples of the purified immunoglobulin myasthenia gravis were purified as anti-affinities. The method of W covalent bond is bonded to the chromatographic medium or cell type, and the organ and tissue derived from the above-mentioned substance 2 are lost, and the protein component is extracted. The sputum/egg sample is passed through the immunoglobulin with healthy individuals, and the protein bound to the immunoglobulin in the official column will flow out of the tube, and then the above-mentioned efflux protein will pass through the immunoglobulin isolated from the MG patient. For each column, all proteins remaining in the second column are candidate autoantigens, which can be used for subsequent analysis: analysis, such as mass spectrometry, to identify various isolated proteins. By the above method, autoantigens of two new patients with myasthenia gravis, HSP60 and HSP90, can be isolated. As a result of ELISA analysis, in the early stage of myasthenia gravis (stage I and Π a), there was no autoantibody that specifically binds AChR, but there is an autoantibody that specifically binds HSP60 and HSP90. The above autologous antibody can provide a new method for detecting myasthenia gravis, because it is generally believed that the specific binding of AChR autoantibodies is accompanied by myasthenia gravis, but in the early stage of patients with myasthenia gravis, there is no such autologous body. The presence of antibodies (see Figure 5). In addition, other methods can be used to isolate candidate autoantigens for myasthenia gravis, such as analysis of cDNA expression gene pools or subtractive phage display systems, to isolate the organs, tissues, or cells of the [ViG etiology and disease development] 23 1357979 species ( mRNAs such as the muscle endplates of mature neuromuscular junctions are separated by phage display or other protein expression databases to isolate possible antigens. The immunoglobulin of the serum from which the autoimmune disorder is to be isolated is analyzed with the above-mentioned database, and the result is compared with the immunoglobulin of the healthy person. There are still differences in the various criteria for screening autoantigens. A suitable technique is selected in the prior methods to study autoimmune diseases, and biological samples can be analyzed to know possible autoantigens and other experimental parameters. Other substitutions and possibilities made by the prior art are readily apparent and are all aspects of the invention. 1. Heat-Shock Protein When the ambient temperature suddenly rises or other adverse conditions, the organism reacts to synthesize a small group of retained proteins called heat shock proteins. In the evolution, the natural heat shock response and the amino acid sequences of various heat shock proteins are very similar. For example, the eukaryotic and prokaryotic heat shock protein 7〇 (HSP7〇) amino acid sequence is about 50% identical (parseu et al., “The function of heat-shock proteins in stress tolerance: degradation and reactivation of damaged protein, Ann. Rev. Genet. 27:437-496 (1993). In stress tolerance, various heat shock proteins play different roles in protecting organisms. a. Heat shock protein 60 (The 60 kD Heat -Shock Protein) Heat shock protein 60 (HSP60) was first discovered in the mitochondrial matrix, which accounts for 1% of all proteins in the mitochondrial matrix (Parsell et al., swpra at 465). Human HSP60 (amino acid sequence: 1) GroEL with E. coli is about 60% identical in the amino acid sequence of 24 1357979. And the above two proteins have the same oligomeric structure, which can constitute a seven-membered ring. Sometimes, a double doughnut structure of two seven-membered rings can be formed. When the temperature rises, the amount of HSP60 increases, and it has the function of ATPase, and ATP bonded to HSP60. Make an appropriate knot on the oligomer HSP60 differs from other heat shock proteins in that it also functions at normal temperatures (/d at 465-66) and can be expressed at all temperatures. HSP60 has unfolded or denatured proteins. The high affinity allows them to fold properly. After the protein is bound to HSP60, the denatured structure can be converted into a secondary structure and inhibit the production of other complexes. b. Heat shock protein 90 (The 90 kD Heat -Shock Proetin) Heat shock protein 90 (shp90) has long been found in the cytoplasm and nucleus of eukaryotes, but has not been found in acellular organisms (parsell et al "swrpa at 470). HSP90 has two isoforms in the cytoplasm, 'HSP90ct, induced expression, main structure (SEQ ID NO: 2) and HSP90p 'sustainability, secondary structure (sequence identification number·· 3) Sreedhar et al., "HSP90 isoform: functions, expression and clinical importance,,, FEBS Letters 56.2:11-1.5 (2004).) At this stage, it is difficult to biochemically distinguish between α-type and β-type, and currently use two. A mixture of HS Ρ 9 。 is studied. Human HSP90a and E. coli HtpG are about 40% identical in amino acid sequence (parsell, MF; να·). HtpG can maintain a certain temperature at normal temperature. Concentration' can be induced in large quantities at high temperatures, but it is not a protein essential for the production of 25 1357979, because the removal of its gene does not affect the growth of E. coli at normal temperature, and only slightly affects Its growth at high temperatures. In contrast, HSP90 is one of the many proteins in eukaryotic cells. In non-adversity, it accounts for 1_2% of all cellular proteins. If the eukaryotic HSP90 gene is used Removal, leading to the death of organisms, indicates that eukaryotic HSP90 has a new function not found in prokaryotes (Sreedhar et al., -ra; Parsell et al., like; HSP90 can interact with many proteins in cells Reactions, including casein kinase 、, heme-regulated eIF-2a kinase, and sterol-like hormone receptors such as estrogen, lutein ( Progesterone), androgen, glucocorticoid, dioxin receptor, src family oncogenic tyrosine kinases of the src family, calmodulin, muscle Actin and tubulin (plus 1) 111111), etc. (?&犷56116{已1.,抓;?^3&1471). It was found through experiments that 'HSP90 plays a role in cell differentiation and development. Multi-functional roles such as regulation of muscle development, early embryonic development to programmed cell death or apoptosis (Sreedhar et al., supra, at 12). In addition, HSP90 has also been shown to be present in a variety of tumors, such as pancreatic cancer, breast cancer, and blood cancer (M at 13). And the ability of HSP9〇p to transcribe is higher in patients with lupus erythematosus, an autoimmune disease caused by autoantibodies attacking their own splice RNA, Ro/La ribosomes (Ro/ La ribonuclear particle), histone and/or natural DNA. 26 1357979 n '& Test kit for measuring autoimmunity The detection method of the present invention can be carried out by a test kit comprising one or more of the above-mentioned techniques for detecting autoantibodies, said autoantibody System-specific autoantigen binding to at least one myasthenia gravis.

Blocking was performed overnight or at 4 ° C overnight. The patient's serum was diluted 1:1,000 in PBST buffer containing 5% ® skim milk powder, and reacted with the blocked PVDF membrane for 1 hour at room temperature. After reacting with the primary antibody, buffered with PBST. The above PVDF membrane was washed with liquid. Subsequently, the secondary antibody was reacted with a secondary antibody at room temperature for 1 hour, and the above secondary antibody was an anti-human IgG labeled with wasabi peroxidase, and diluted 1:5,000 in PBST buffer containing 5% skim milk powder. The above secondary antibody was purchased from Biosource International, of Camarillo, CA. USA, Fcr (Jackson immunoResearcli Laboratories, Inc.) of horseradish peroxidase-conjugated mouse anti-human IgG. After the antigen was bound to the autoantibody, ENG (Amersham Pharmacia Biotech) was used to perform cold light analysis of the yeast. • Figures 1 and 2 show the results of this example. Samples were taken from female patients with thymic hyperplasia (HF), male patients with thymic hyperplasia (HM), female patients with thymoma (TF), and male patients with thymoma. (TM). A positive reaction is indicated by 'dot", and is an autoantibody having a recognizable heat shock protein 60 and a heat shock protein 90. The results confirmed that patients with myasthenia gravis have autoantibodies that can specifically bind heat shock protein 60 and heat shock protein 90. Example 2: Detection of autoantibodies by enzyme-linked immunosorbent assay The serum samples of Example 1 were quantitatively analyzed by enzyme-linked immunosorbent assay. Human HSP60 (purified from c.cW) or HSP90 (purified from S. cerevbz'fle) was coated on ELISA microplates at 4 °C with 0.1 M NaHC03, pH = 8.6 (Corning Life Sciences, New York) , NY, USA). The above two recombinant heat shock proteins were purchased from Sigama_Aldrich Co. The completed microplate was washed 3 times with PBS for 1 minute each time, and reacted with 200 μΐ of blocking solution (5 mg/ml of BSA in PBST) for 1 hour at 37 ° C, and then blocked. The solution was washed 6 times each time. Then, it is reacted with the diluted patient serum at 37 ° C for 1 hour to 30 minutes, and then washed 6 times with PBST for 1 minute each time, and finally reacted with a secondary antibody, which is a mouse anti-marked horseradish peroxidase. Human IgG Fcr (Jackson immunoResearch Laboratories, Inc.) was diluted 1: 10,000 in PBST buffer containing 5 mg/ml BSA, reacted at room temperature for 1 hour, and contained 5 mg/ml BSA at room temperature. The PBST buffer was washed 6 times and 100 μM of 3,3',5,5'-tetradecyl-p-diaminobiphenyl (TMB) solution was added. The above hydrazine solution was prepared as 50 mM citrate phosphate. After the TMB solution was added, the reaction was carried out for 30 minutes at room temperature, and the absorbance at a wavelength of 450 nm was measured by an MRX Microplate Reader (Dynex Technologies) in accordance with the instrument's operation manual. Figures 3 (HSP60) and 笫4 (HSP90) show the results of ELISA analysis of the control group and the myasthenia gravis patients at all times. The average value of the absorbance at a wavelength of 450 nm is represented by a bar. This embodiment does not distinguish between Γ357979 HSP90a and HSP9〇P. The above results indicate that all patients with myasthenia gravis have autologous antibodies that specifically bind HSP60 and HSP90. Table 1 shows that there is no autoantibody that specifically binds AChR in patients with type I and type D MG, but it has autologous antibodies that specifically bind HSP60 and HSP90, so it can correctly identify myasthenia gravis. patient. Fourteen patients with autologous antibodies that specifically bind HSP60 and HSP90 were analyzed by ELISA. It was found that 24 patients with type I MG and 16 patients with type Π a had autologous antibodies that specifically bind HSP60 and HSP90. . The process of fractionation is disclosed in Example 2. The basis for determining the presence of protein is: (1) OD450 = 0.2 (AChR); (2) OD45 〇 = 0.375 (HSP60); (3) OD450 = 0.232 (HSP90). None of the 40 patients detected autoantibodies that specifically bind AChR (indicated by AChR), and 28 of them were able to detect autoantibodies that specifically bind HSP60 (24-bit) Eighteen of the type I patients were detectable, and 10 of the 16 Ha-type patients were detectable). Thirty-three patients were able to detect autoantibodies that specifically bind HSP90 (21 of 24 patients with type I can detect it, and 1 of 16 patients with IT a can detect it) ).

'Sensitivity' is a self-antibody that detects specific binding to HSP60 ("protein_l") or HSP90 ("protein_2") in order to calculate the proportion of patients identified as MG (Hennekens et al, Epidemiology in medicine 331-335 (lst ed. 1987)). Specificity" is to calculate the proportion of non-MG patients who do not detect autoantibodies that specifically bind HSI>6〇 ("protein_r" or HSP90 ("pr〇tein_2"). Myasthenia gravis (type I) and mild systemic (na-type) MG patients do not have autologous antibodies that can be specifically linked to AChR, while 76% of patients have specific bonds with 33 1357979 HSP60 Autoantibodies of the knot, and 86% of patients have autoantibodies that can be specifically linked to HSP90. In addition, 91% of patients with non-myasthenia gravis do not detect autologous bonds that are specific to HSP60. Antibodies, 86% of patients with non-myasthenia gravis do not detect autoantibodies that bind specifically to HSP90. Table 2 shows autoantibody-specific linkages HSP60, HSP90, HSP60+HSP90, AChR+HSP60, Or the analysis of AChR+HSP90, etc. The results of the above analysis can provide a better method than the AChR autoantibody of only type I MG patients. The data of this example are summarized in Table 2, where 73 笫I type MG Patient samples were analyzed by ELISA' and the criteria for their determination have been disclosed in Table 1.
