Description

肉芽腫性疾患バイオマーカーGranulomatous disease biomarkers
 本発明は、肉芽腫性疾患バイオマーカー等に関する。 The present invention relates to granuloma disease biomarkers and the like.
 サルコイドーシスは、肉芽腫性疾患の1種であり、非乾酪性肉芽腫が全身に形成される原因不明の難病である。肉芽腫が可逆的で自然治癒する症例があるものの、肺、限、心臓をはじめとして多臓器に病変が出現し、不可逆となって線維化を起こし重篤な臓器障害をきたす予後不良例も存在する。細菌感染などの抗原曝露という単一の環境因子のみでは説明できず、複数の遺伝的要因が関連する。 Sarcoidosis is a type of granulomatous disease, and it is an incurable disease of unknown cause in which non-caseating granulomas are formed throughout the body. Although there are cases in which granulomas are reversible and spontaneously healed, there are also cases with poor prognosis in which lesions appear in multiple organs including the lungs, margins, and heart, causing irreversible fibrosis and serious organ damage. To do. A single environmental factor of antigenic exposure, such as a bacterial infection, cannot be explained and multiple genetic factors are involved.
 サルコイドーシスの血清バイオマーカーに、ACEやsIL-2レセプターがあるものの、感度及び特異度共に十分ではなく、新たなバイオマーカーの開発が急務とされる。 Despite the presence of ACE and sIL-2 receptors as serum biomarkers for sarcoidosis, their sensitivity and specificity are not sufficient, and the development of new biomarkers is urgently needed.
 血清は、非侵襲的に繰り返し採取可能な理想的なサンプルと考えられるものの、バイオマーカーの観点から爽雑物とされるタンパク(アルブミンなど)を豊富に含む。このため、血清をサンプルとしてバイオマーカーを探索しても、満足な結果が得られない。COPDと喘息を鑑別可能なバイオマーカーに関する近年の報告(非特許文献1)では、2次元電気泳動法によるゲルを用いた分離による質量分析技術で、大量爽雑物を含む血清を用いたため、見出されたバイオマーカーは、プロトロンビンを含む血清夾雑物のみであった。 Although serum is considered to be an ideal sample that can be repeatedly collected non-invasively, it contains abundant proteins (albumin etc.) that are considered as contaminants from the viewpoint of biomarkers. Therefore, even if a biomarker is searched using serum as a sample, satisfactory results cannot be obtained. A recent report on a biomarker capable of differentiating between COPD and asthma (Non-patent Document 1) shows that serum containing a large amount of contaminants was used in a mass spectrometry technique by separation using a gel by a two-dimensional electrophoresis method. The only biomarkers released were serum contaminants containing prothrombin.
 本発明は、肉芽腫性疾患のバイオマーカー及びその利用方法を提供することを課題とする。 An object of the present invention is to provide a biomarker for granulomatous disease and a method for using the biomarker.

 対象タンパク質の遺伝子siRNAは、対象タンパク質をコードする遺伝子の発現を特異的に抑制する二本鎖RNA分子である限り特に制限されない。一実施形態において、siRNAは、例えば、18塩基以上、19塩基以上、20塩基以上、又は21塩基以上の長さであることが好ましい。また、siRNAは、例えば、25塩基以下、24塩基以下、23塩基以下、又は22塩基以下の長さであることが好ましい。ここに記載するsiRNAの長さの上限値及び下限値は任意に組み合わせることが想定される。例えば、下限が18塩基であり、上限が25塩基、24塩基、23塩基、又は22塩基である長さ;下限が19塩基であり、上限が25塩基、24塩基、23塩基、又は22塩基である長さ;下限が20塩基であり、上限が25塩基、24塩基、23塩基、又は22塩基である長さ;下限が21塩基であり、上限が25塩基、24塩基、23塩基、又は22塩基である長さの組み合わせが想定される。 The gene siRNA of the target protein is not particularly limited as long as it is a double-stranded RNA molecule that specifically suppresses the expression of the gene encoding the target protein. In one embodiment, the siRNA preferably has a length of, for example, 18 bases or more, 19 bases or more, 20 bases or more, or 21 bases or more. Moreover, the siRNA preferably has a length of, for example, 25 bases or less, 24 bases or less, 23 bases or less, or 22 bases or less. It is assumed that the upper limit value and the lower limit value of the siRNA length described here are arbitrarily combined. For example, the lower limit is 18 bases, the upper limit is 25 bases, 24 bases, 23 bases, or 22 bases length; the lower limit is 19 bases, the upper limit is 25 bases, 24 bases, 23 bases, or 22 bases Certain length; lower limit is 20 bases, upper limit is 25 bases, 24 bases, 23 bases, or 22 bases Length; lower limit is 21 bases, upper limit is 25 bases, 24 bases, 23 bases, or 22 Combinations of lengths that are bases are envisioned.
 siRNAは、shRNA(small hairpin RNA)であっても良い。shRNAは、その一部がステムループ構造を形成するように設計することができる。例えば、shRNAは、ある領域の配列を配列aとし、配列aに対する相補鎖を配列bとすると、配列a、スペーサー、配列bの順になるようにこれらの配列が一本のRNA鎖に存在するようにし、全体で45~60塩基の長さとなるように設計することができる。配列aは、標的となる対象タンパク質をコードする塩基配列の一部の領域の配列であり、標的領域は特に限定されず、任意の領域を候補にすることが可能である。そして配列aの長さは19~25塩基、好ましくは19~21塩基である。 SiRNA may be shRNA (small hairpin RNA). shRNA can be designed such that a part thereof forms a stem-loop structure. For example, in shRNA, if the sequence of a certain region is sequence a and the complementary strand to sequence a is sequence b, then these sequences are present in one RNA strand in the order of sequence a, spacer, sequence b. And can be designed to be 45-60 bases in length. Sequence a is a sequence of a partial region of the base sequence encoding the target protein to be targeted, and the target region is not particularly limited, and any region can be used as a candidate. The length of the sequence a is 19 to 25 bases, preferably 19 to 21 bases.
 対象タンパク質の遺伝子特異的siRNAは、5’又は3’末端に、付加的な塩基を有していてもよい。該付加的塩基の長さは、通常2~4塩基程度である。該付加的塩基は、DNAでもRNAでもよいが、DNAを用いると核酸の安定性を向上させることができる場合がある。このような付加的塩基の配列としては、例えばug-3’、uu-3’、tg-3’、tt-3’、ggg-3’、guuu-3’、gttt-3’、ttttt-3’、uuuuu-3’などの配列が挙げられるが、これらに限定されるものではない。 The gene-specific siRNA of the target protein may have an additional base at the 5'or 3'end. The length of the additional base is usually about 2 to 4 bases. The additional base may be DNA or RNA, but the use of DNA may improve the stability of nucleic acid in some cases. Such additional base sequences include, for example, ug-3', uu-3', tg-3', tt-3', ggg-3', guuu-3', gttt-3', ttttt-3'. Examples include, but are not limited to, sequences such as', uuuuu-3'.
 siRNAは、3'末端に突出部配列(オーバーハング)を有していてもよく、具体的には、dTdT(dTはデオキシチミジンを表わす)を付加したものが挙げられる。また、末端付加がない平滑末端(ブラントエンド)であってもよい。siRNAは、センス鎖とアンチセンス鎖が異なる塩基数であってもよく、例えば、アンチセンス鎖が3'末端及び5'末端に突出部配列(オーバーハング)を有している「asymmetrical interfering RNA(aiRNA)」を挙げることができる。典型的なaiRNAは、アンチセンス鎖が21塩基からなり、センス鎖が15塩基からなり、アンチセンス鎖の両端で各々3塩基のオーバーハング構造をとる。 SiRNA may have a protruding sequence (overhang) at the 3'end, and specific examples thereof include dTdT (dT represents deoxythymidine). In addition, it may be a blunt end with no terminal addition. The siRNA may have a different number of bases in the sense strand and the antisense strand, and for example, the “asymmetrical interfering RNA (where the antisense strand has a protruding sequence (overhang) at the 3′ end and 5′ end) ( aiRNA)". A typical aiRNA has an antisense strand of 21 bases, a sense strand of 15 bases, and an overhang structure of 3 bases at each end of the antisense strand.
 対象タンパク質の遺伝子特異的siRNAの標的配列の位置は特に制限されるわけではないが、一実施形態において、5’-UTR及び開始コドンから約50塩基まで、並びに3’-UTR以外の領域から標的配列を選択することが望ましい。選択された標的配列の候補群について、標的以外のmRNAにおいて16-17塩基の連続した配列に相同性がないかどうかを、BLAST(http://www.ncbi.nlm.nih.gov/BLAST/)などのホモロジー検索ソフトを用いて調べ、選択した標的配列の特異性を確認することが好ましい。特異性が確認された標的配列について、AA(もしくはNA)以降の19-21塩基にTTもしくはUUの3’末端オーバーハングを有するセンス鎖と、該19-21塩基に相補的な配列及びTTもしくはUUの3’末端オーバーハングを有するアンチセンス鎖とからなる2本鎖RNAをsiRNAとして設計してもよい。また、siRNAの前駆体であるshRNAは、ループ構造を形成しうる任意のリンカー配列(例えば、5-25塩基程度)を適宜選択し、上記センス鎖とアンチセンス鎖とを該リンカー配列を介して連結することにより設計することができる。 The position of the target sequence of the gene-specific siRNA of the protein of interest is not particularly limited, but in one embodiment, it is targeted from a region other than the 5'-UTR and the start codon to about 50 bases and the 3'-UTR. It is desirable to choose the sequence. Regarding the candidate group of the selected target sequence, BLAST (http://www.ncbi.nlm.nih.gov/BLAST/ It is preferable to check the specificity of the selected target sequence by using a homology search software such as ). Regarding the target sequence whose specificity was confirmed, a sense strand having a 3'terminal overhang of TT or UU at 19-21 bases after AA (or NA), a sequence complementary to the 19-21 bases and TT or Double-stranded RNA consisting of an antisense strand having a 3'-terminal overhang of UU may be designed as siRNA. In addition, for shRNA that is a precursor of siRNA, any linker sequence capable of forming a loop structure (for example, about 5-25 bases) is appropriately selected, and the sense strand and the antisense strand are linked via the linker sequence. It can be designed by connecting.

 siRNAは、mRNA上の標的配列のセンス鎖及びアンチセンス鎖をDNA/RNA自動合成機でそれぞれ合成し、適当なアニーリング緩衝液中、約90~約95℃で約1分程度変性させた後、約30~約70℃で約1~約8時間アニーリングさせることにより調製することができる。また、siRNAの前駆体となるshRNAを合成し、これを、RNA切断タンパク質ダイサー(dicer)を用いて切断することにより調製することもできる。 siRNA is a DNA/RNA automatic synthesizer that synthesizes the sense and antisense strands of the target sequence on mRNA, and denatures them in an appropriate annealing buffer at about 90 to about 95°C for about 1 minute, It can be prepared by annealing at about 30 to about 70° C. for about 1 to about 8 hours. In addition, it can also be prepared by synthesizing shRNA as a precursor of siRNA and cleaving it with an RNA cleaving protein dicer.
 対象タンパク質の遺伝子特異的miRNAは、対象タンパク質をコードする遺伝子の翻訳を阻害する限り任意である。例えば、miRNAは、siRNAのように標的mRNAを切断するのではなく、標的の3’非翻訳領域(UTR)に対合してその翻訳を阻害してもよい。miRNAは、pri-miRNA(primary miRNA)、pre-miRNA(precursor miRNA)、及び成熟miRNAのいずれでもよい。miRNAの長さは特に制限されず、pri-miRNAの長さは通常数百~数千塩基であり、pre-miRNAの長さは通常50~80塩基であり、成熟miRNAの長さは通常18~30塩基である。一実施形態において、対象タンパク質の遺伝子特異的miRNAは、好ましくはpre-miRNA又は成熟miRNAであり、より好ましくは成熟miRNAである。このような対象タンパク質の遺伝子特異的miRNAは、公知の手法で合成してもよく、合成RNAを提供する会社から購入してもよい。 The gene-specific miRNA of the target protein is optional as long as it inhibits the translation of the gene encoding the target protein. For example, miRNAs may pair with the 3'untranslated region (UTR) of the target and inhibit its translation rather than cleaving the target mRNA like siRNA. The miRNA may be any of pri-miRNA (primary miRNA), pre-miRNA (precursor miRNA), and mature miRNA. The length of miRNA is not particularly limited, the length of pri-miRNA is usually several hundred to several thousand bases, the length of pre-miRNA is usually 50 to 80 bases, and the length of mature miRNA is usually 18 ~30 bases. In one embodiment, the gene-specific miRNA of the protein of interest is preferably pre-miRNA or mature miRNA, more preferably mature miRNA. Such gene-specific miRNA of the target protein may be synthesized by a known method, or may be purchased from a company that provides synthetic RNA.
 対象タンパク質の遺伝子特異的アンチセンス核酸とは、対象タンパク質をコードする遺伝子のmRNAの塩基配列と相補的もしくは実質的に相補的な塩基配列又はその一部を含む核酸であって、該mRNAと特異的かつ安定した二重鎖を形成して結合することにより、対象タンパク質合成を抑制する機能を有する核酸である。アンチセンス核酸はDNA、RNA、DNA/RNAキメラのいずれでもよい。アンチセンス核酸がDNAの場合、標的RNAとアンチセンスDNAとによって形成されるRNA:DNAハイブリッドは、内在性リボヌクレアーゼH(RNase H)に認識されて標的RNAの選択的な分解を引き起こす。したがって、RNase Hによる分解を指向するアンチセンスDNAの場合、標的配列は、mRNA中の配列だけでなく、対象タンパク質の遺伝子の初期翻訳産物におけるイントロン領域の配列であってもよい。イントロン配列は、ゲノム配列と、対象タンパク質の遺伝子のcDNA塩基配列とをBLAST、FASTAなどのホモロジー検索プログラムを用いて比較することにより、決定することができる。 The gene-specific antisense nucleic acid of the target protein is a nucleic acid containing a base sequence complementary or substantially complementary to the base sequence of mRNA of the gene encoding the target protein, or a part thereof, and is specific to the mRNA. It is a nucleic acid having a function of suppressing target protein synthesis by forming a stable and stable double chain and binding. The antisense nucleic acid may be DNA, RNA, or a DNA/RNA chimera. When the antisense nucleic acid is DNA, the RNA:DNA hybrid formed by the target RNA and the antisense DNA is recognized by the endogenous ribonuclease H (RNaseH) and causes selective degradation of the target RNA. Therefore, in the case of antisense DNA that directs degradation by RNase H, the target sequence may be not only the sequence in mRNA but also the sequence of the intron region in the initial translation product of the gene of the target protein. The intron sequence can be determined by comparing the genomic sequence with the cDNA base sequence of the gene of the target protein using a homology search program such as BLAST or FASTA.
 対象タンパク質の遺伝子特異的アンチセンス核酸の標的領域は、該アンチセンス核酸がハイブリダイズすることにより、結果として対象タンパク質への翻訳が阻害されるものであればその長さは制限されない。対象タンパク質の遺伝子特異的アンチセンス核酸は、対象タンパク質をコードするmRNAの全配列であっても部分配列であってもよい。合成の容易さや抗原性、細胞内移行性の問題などを考慮すれば、約10~約40塩基、特に約15~約30塩基からなるオリゴヌクレオチドが好ましいが、これらに限定されるものではない。より具体的には、対象タンパク質の遺伝子の5’端ヘアピンループ、5’端非翻訳領域、翻訳開始コドン、タンパク質コード領域、ORF翻訳終止コドン、3’端非翻訳領域、3’端パリンドローム領域又は3’端ヘアピンループなどをアンチセンス核酸の好ましい標的領域として選択しうるが、それらに限定されるものではない。 The length of the target region of the gene-specific antisense nucleic acid of the target protein is not limited as long as the antisense nucleic acid hybridizes with the result that the translation into the target protein is inhibited. The gene-specific antisense nucleic acid of the target protein may be the entire sequence or a partial sequence of mRNA encoding the target protein. Considering the problems of easiness of synthesis, antigenicity, intracellular transfer, etc., an oligonucleotide consisting of about 10 to about 40 bases, particularly about 15 to about 30 bases is preferable, but not limited thereto. More specifically, 5'end hairpin loop of the gene of the target protein, 5'end untranslated region, translation initiation codon, protein coding region, ORF translation stop codon, 3'end untranslated region, 3'end palindromic region Alternatively, a 3′-end hairpin loop or the like may be selected as a preferred target region of the antisense nucleic acid, but is not limited thereto.
 対象タンパク質の遺伝子特異的アンチセンス核酸は、対象タンパク質の遺伝子のmRNAや初期転写産物とハイブリダイズしてタンパク質への翻訳を阻害するだけでなく、二本鎖DNAであるこれらの遺伝子と結合して三重鎖(トリプレックス)を形成し、RNAへの転写を阻害し得るもの(アンチジーン(antigene))であってもよい。 The gene-specific antisense nucleic acid of the target protein not only hybridizes with the mRNA of the gene of the target protein or the initial transcription product to inhibit translation into a protein but also binds to these genes that are double-stranded DNA. It may be one that can form a triplex and inhibit transcription into RNA (antigene).
 上記した対象タンパク質の遺伝子特異的siRNA、対象タンパク質の遺伝子特異的miRNA、及び対象タンパク質の遺伝子特異的アンチセンス核酸を構成するヌクレオチド分子は、安定性(化学的及び/又は対酵素)や比活性(RNAとの親和性)を向上させるために、種々の化学修飾を含んでもよい。例えば、ヌクレアーゼなどの加水分解酵素による分解を防ぐために、アンチセンス核酸を構成する各ヌクレオチドのリン酸残基(ホスフェート)を、例えば、ホスホロチオエート(phosphorothioate; PS)、メチルホスホネート(methylphosphonate)、ホスホロジチオネート(phosphorodithioate)などの化学修飾リン酸残基に置換することができる。また、各ヌクレオチドの糖(リボース)の2’位の水酸基を、-OR(R=CH3(2’-O-Me)、CH2CH2OCH3(2’-O-MOE)、CH2CH2NHC(NH)NH2、CH2CONHCH3、又はCH2CH2CNなど)に置換してもよい。さらに、塩基部分(ピリミジン、プリン)に化学修飾を施してもよく、例えば、ピリミジン塩基の5位へのメチル基やカチオン性官能基の導入、あるいは2位のカルボニル基のチオカルボニルへの置換などを施してもよい。また、siRNAやmiRNAを構成するヌクレオチド分子の一部は、天然型のDNAに置換されていてもよい。 The nucleotide molecules constituting the gene-specific siRNA of the target protein, the gene-specific miRNA of the target protein, and the gene-specific antisense nucleic acid of the target protein described above have stability (chemical and/or counterenzyme) and specific activity ( Various chemical modifications may be included in order to improve (affinity with RNA). For example, in order to prevent degradation by a hydrolase such as nuclease, a phosphate residue (phosphate) of each nucleotide constituting an antisense nucleic acid is converted into, for example, phosphorothioate (PS), methylphosphonate, or phosphorodithioate. It may be replaced with a chemically modified phosphate residue such as phosphorodithioate. In addition, the hydroxyl group at the 2'position of the sugar (ribose) of each nucleotide is replaced with -OR (R=CH 3 (2'-O-Me), CH 2 CH 2 OCH 3 (2'-O-MOE), CH 2 CH 2 NHC(NH)NH 2 , CH 2 CONHCH 3 , or CH 2 CH 2 CN etc.). Further, the base moiety (pyrimidine, purine) may be chemically modified, for example, introduction of a methyl group or a cationic functional group at the 5-position of the pyrimidine base, or substitution of the carbonyl group at the 2-position with thiocarbonyl. May be given. In addition, a part of the nucleotide molecule constituting siRNA or miRNA may be replaced with natural DNA.

It can be prepared by determining the sequence and using a commercially available DNA/RNA automatic synthesizer to synthesize a sequence complementary thereto.

Typically, the expression vector comprises a promoter sequence and a gene-specific siRNA of the protein of interest, a gene-specific miRNA of the protein of interest, a gene-specific antisense nucleic acid of the protein of interest, or a coding sequence of the protein of interest (if necessary). And a polynucleotide containing a transcription termination signal sequence), and optionally other sequences. The promoter is not particularly limited, and examples thereof include RNAV polymerase II (polII) promoters such as CMV promoter, EF1 promoter, SV40 promoter, MSCV promoter, hTERT promoter, β-actin promoter, and CAG promoter; mouse and human U6-snRNA promoters, Examples include RNA polymerase III (pol III) type promoters such as human H1-RNase P RNA promoter and human valine-tRNA promoter. The other sequence is not particularly limited, and various known sequences that can be contained in the expression vector can be adopted. Examples of such sequences include an origin of replication, a drug resistance gene, and the like. Moreover, the types of drug resistance genes and types of vectors can be exemplified as described above.
 対象タンパク質の遺伝子発現抑制剤の別の例としては、対象タンパク質の遺伝子特異的リボザイムなどが挙げられる。「リボザイム」とは、狭義には、核酸を切断する酵素活性を有するRNAを意味するが、本願では配列特異的な核酸切断活性を有する限りDNAをも包含する。リボザイム核酸として最も汎用性の高いものは、ウイロイドやウイルソイドなどの感染性RNAに見られるセルフスプライシングRNAがあり、ハンマーヘッド型やヘアピン型などが知られている。ハンマーヘッド型は約40塩基程度で酵素活性を発揮し、ハンマーヘッド構造をとる部分に隣接する両端の数塩基ずつ(合わせて約10塩基程度)をmRNAの所望の切断部位と相補的な配列にすることにより、標的mRNAのみを特異的に切断することが可能である。このタイプのリボザイム核酸は、RNAのみを基質とするので、ゲノムDNAを攻撃することがないという利点を有する。対象タンパク質の遺伝子のmRNAが自身で二本鎖構造をとる場合には、RNAヘリカーゼと特異的に結合し得るウイルス核酸由来のRNAモチーフを連結したハイブリッドリボザイムを用いることにより、標的配列を一本鎖にすることができる[Proc. Natl. Acad. Sci. USA, 98(10): 5572-5577 (2001)]。さらに、リボザイムを、それをコードするDNAを含む発現ベクターの形態で使用する場合には、転写産物の細胞質への移行を促進するために、tRNAを改変した配列をさらに連結したハイブリッドリボザイムとすることもできる[Nucleic Acids Res., 29(13): 2780-2788 (2001)]。 Another example of the gene expression inhibitor of the target protein is a gene-specific ribozyme of the target protein. The term "ribozyme" means, in a narrow sense, RNA having an enzymatic activity of cleaving nucleic acid, but in the present application, it also includes DNA as long as it has sequence-specific nucleic acid cleaving activity. The most versatile ribozyme nucleic acid is self-splicing RNA found in infectious RNA such as viroid and virusoid, and hammerhead type and hairpin type are known. The hammerhead type exerts enzyme activity with about 40 bases, and several bases at both ends adjacent to the part having the hammerhead structure (about 10 bases in total) are made into sequences complementary to the desired cleavage site of mRNA. By doing so, it is possible to specifically cleave only the target mRNA. This type of ribozyme nucleic acid has an advantage that it does not attack genomic DNA because it uses only RNA as a substrate. When the mRNA of the gene of the target protein has a double-stranded structure by itself, by using a hybrid ribozyme in which an RNA motif derived from a viral nucleic acid that can specifically bind to RNA helicase is used, the target sequence is single-stranded. [Proc.Natl. Acad. Sci. USA, 98(10): 5572-5577 (2001)]. Furthermore, when the ribozyme is used in the form of an expression vector containing the DNA encoding the ribozyme, in order to promote the translocation of the transcript to the cytoplasm, it should be a hybrid ribozyme further linked with a tRNA-modified sequence. You can also do it [Nucleic Acids Res., 29(13):2780-2788(2001)].

 試験例1.細胞外小胞画分の調製1
 サルコイドーシスであると診断されたヒト被検体(7名)それぞれの血清、及び健常ヒト被検体(5名)それぞれの血清から細胞外小胞画分を調製した。細胞外小胞画分の調製は、各検体の血清の容量を揃えて、細胞外小胞精製カラム(EV-Second、ジーエルサイエンス社製)を用いて行った。
Test example 1. Preparation of extracellular vesicle fraction 1
Extracellular vesicle fractions were prepared from the serum of each human subject (7 persons) diagnosed as having sarcoidosis and the serum of each healthy human subject (5 persons). The extracellular vesicle fraction was prepared using the extracellular vesicle purification column (EV-Second, manufactured by GL Sciences Inc.) with the same volume of serum for each sample.
 サルコイドーシス被検体については、ステロイド治療(プレドニン15-30mg/bodyを初期量として投与)後、上記と同様にして細胞外小胞画分を調製した。 For sarcoidosis subjects, extracellular vesicle fractions were prepared in the same manner as above, after steroid treatment (predonin 15-30 mg/body was administered as the initial dose).
 続いて、得られた細胞外小胞画分について、細胞外小胞の粒子数及び粒子径を測定した。具体的には、ナノサイト(日本カンタム・デザイン株式会社、Nanoparticle Tracking Analysis (NTA) Version 2.3 Build 0025)を使用して測定した。これは、粒子径ごとのブラウン運動速度の違いをもとに解析するものであり、画面に映る散乱光1つ1つの動きを追尾(トラッキング)し、各々の移動速度(拡散係数)から液中における粒子径(流体力学径)を算出することができる。結果を図1及び図2に示す。 Next, the number of extracellular vesicle particles and the particle size of the obtained extracellular vesicle fraction were measured. Specifically, the measurement was performed using a nanosite (Nippon Quantum Design Co., Ltd., Nanoparticle Tracking Analysis (NTA) Version 2.3 Build 0025). This is an analysis based on the difference in Brownian motion velocity for each particle size. The movement of each scattered light reflected on the screen is tracked (tracked), and the movement velocity (diffusion coefficient) of each scattered light The particle diameter (fluid dynamic diameter) in can be calculated. The results are shown in FIGS. 1 and 2.

Specifically, it carried out as follows. The fixed extracellular vesicle solution was placed on the grid in an amount of 5 to 8 μL and allowed to stand for 15 minutes to fix the extracellular vesicles to the form bar of the grid. After washing 3 times with PBS, blocking reaction (1% BSA/PBS, 10 minutes) is performed, followed by primary antibody reaction (Invitrogen AHS0902 Mouse (monoclonal) Anti-Human Leukemia and Platelet Associated Antigen CD9 Clone: MM2/57, Diluted 100 times, 2 hours and a half, at room temperature). After washing 6 times with PBS, a secondary antibody reaction (CRLEMGMHL10 Anti-IgG (H+L), Mouse, Goat-Poly, Gold 10 nm, EM, 200-fold dilution, 1 hour, room temperature) was performed. After washing 6 times with PBS, it was treated with 1% GA/PBS for 15 minutes and further washed 3 times with PBS. It was washed with water, treated with 0.5% UA (uranyl acetate), dried and observed with an electron microscope. The obtained results are shown in FIG.
 またさらに、細胞外小胞画分について、エクソソームマーカーに対する抗体(抗CD9抗体(Invitrogen, clone=MM2/57))を用いて、ウェスタンブロットした。結果を図4に示す。 Furthermore, the extracellular vesicle fraction was Western blotted using an antibody against the exosome marker (anti-CD9 antibody (Invitrogen, clone=MM2/57)). The results are shown in Fig. 4.
 図1~4に示されるように、得られた画分にはエクソソームが存在しており、その粒子数及び粒子径は、健常被検体とサルコイドーシス被検体とでほぼ差が見られないことが分かった。 As shown in FIGS. 1 to 4, exosomes were present in the obtained fractions, and it was found that there is almost no difference in the number of particles and the particle size between the healthy subject and the sarcoidosis subject. It was

Test Example 8. Evaluation of the diagnostic ability of sarcoidosis biomarkers 1
Based on the quantification results of Test Example 4, an ROC curve was prepared when Monocyte differentiation antigen CD14 (CD14) and Lipopolysaccharide-binding protein (LBP) were used alone as sarcoidosis biomarkers. Specifically, using the statistical software JMP, an ROC curve was created with the vertical axis representing the sensitivity (positive rate) and the horizontal axis representing the value obtained by subtracting specificity from 1 (1-specificity) (false positive rate). .. The results are shown in Fig. 10. Furthermore, the AUC when both CD14 and LBP were used was calculated by logistic regression analysis and found to be 0.89.
 サルコイドーシスの既存の血清バイオマーカー(ACE)を使用した場合のAUCは0.69であることが報告されている。一方、図10に示されるように、CD14及びLBPそれぞれ単独をバイオマーカーとして使用した場合のAUCは0.8以上であり、またこれらを組合わせることにより0.9近いAUCが得られた。このことから、これらのバイオマーカーは、既存のバイオマーカーよりも診断能が優れていることが分かった。 AUC using existing serum biomarkers (ACE) for sarcoidosis has been reported to be 0.69. On the other hand, as shown in FIG. 10, the AUC when using CD14 and LBP alone as biomarkers was 0.8 or more, and by combining these, an AUC close to 0.9 was obtained. From this, it was found that these biomarkers have a better diagnostic ability than existing biomarkers.
