Definitions
- This application relates to immune cell therapy.
- the present application relates to a method for inducing cells that can be used in immune cell therapy by introducing a T cell receptor gene exhibiting a desired antigen specificity into pluripotent stem cells.
- TCRs T cell receptors
- T cells immortalized includes fusion with cancer cells and long-term culture by TCR stimulation and cytokine stimulation.
- TCR stimulation and cytokine stimulation include fusion with cancer cells and long-term culture by TCR stimulation and cytokine stimulation.
- the T cells immortalized in this way are so-called cancer cells, and autotransplantation to return to the patient himself is dangerous. There is also a problem that the function is lowered in the cloning step.
- A. Cloning method using initialization technique A technique to solve the problem of T cell cloning for autologous transplantation has been proposed. This is a method of cloning as a stem cell having a specific TCR gene structure by using a reprogramming technique. Specifically, it is a method for producing pluripotent stem cells from T cells by nuclear transfer, iPS cell transformation, etc., and patent applications have been filed (WO2008 / 038579, WO2011 / 096482). Papers on such methods have been published in 2010 and 2013.
- This method is premised on autotransplantation in which ES cells or iPS cells are produced from the patient's own T cells, amplified, and the T cells are regenerated and returned to the patient.
- this method has at least the following three problems. A1) It is necessary to prepare iPS cells for each patient and cannot be prepared in advance. A2) Since iPS cells are prepared individually, each time they are prepared in terms of their effectiveness and safety and the quality of iPS cells. A3) T cells derived from T-iPS cells may become cancerous.
- TCR gene transfer T cell therapy The antigen-specific T cell receptor (TCR) gene is isolated, and the gene is expressed in the patient's normal T cells (a collection of many clones) and returned to the patient's body (autologous transplantation) There are several clinical trials of gene therapy in various regions (Morgan RA et al, Science, 314: 126. 2006). This method suppresses the expression of TCRs originally expressed by normal T cells of patients with, for example, siRNA (Okamoto S et al, Cancer Res 69: 9003, 2009), and self-expresses T cells that express only specific TCRs. Transplant. For example, a WT1 antigen-specific T cell receptor (TCR) gene has been isolated, and gene therapy for cancers that express WT1 has been performed.
- TCR antigen-specific T cell receptor
- T cells used for treatment are prepared from the patient's own T cells.
- the method B has the following three problems. B1) Since it is gene therapy, patient T cells may become cancerous. B2) Inhibition of endogenous TCR of T cells to be transplanted is not complete, and there is a risk of unexpected reactivity appearing. B3) Since it is a treatment for each patient, advance preparations cannot be made.
- Donor lymphocyte infusion therapy Bone marrow transplantation for tumors of the blood system such as leukemia has an aspect of immune cell therapy. That is, T cells contained in transplanted donor bone marrow cells are expected to attack the leukemia cells of the recipient. In order to enhance the effect, donor lymphocyte infusion is also known, in which only donor T cells are administered later. In recent years, a method has been reported in which T cells amplified as a clone for a desired antigen are transfused (Chapuis et al, Sci Transl Med, 5: 174ra27, 2013).
- the T cells used for treatment are cells derived from another donor
- the recipient's hematopoietic system after receiving a bone marrow transplant is the same as that of the donor. Is essentially regarded as a kind of autograft. This method requires prior bone marrow transplantation and the patient must receive an immunosuppressant for life.
- T cells As described above, various immune cell therapies using T cells have been proposed. Except for D, all of them are autotransplants or transplants of T cells under conditions that are considered autotransplants. Transplantation of T cells is contrary to the common sense of immune cell therapy. For example, in malignant tumors of the blood system (such as leukemia), bone marrow transplantation that transplants hematopoietic stem cells is performed, but is usually transplanted from an HLA-type donor that matches the recipient so that the donor's bone marrow is not rejected by the recipient. The However, in other humans, amino acid sequences are mismatched in many protein molecules other than HLA, and donor T cells can recognize these mismatches as targets for attack.
- This application aims to provide a more efficient, effective and safe immunotherapy.
- the present application derives a T progenitor cell or a mature T cell from a pluripotent stem cell having a desired antigen-specific T cell receptor gene, and the T progenitor cell or mature T cell is more than a certain amount with a donor from which the pluripotent stem cell is derived.
- Provide immune cell therapy including transplantation to patients with common HLA types.
- a pluripotent stem cell having a desired antigen-specific T cell receptor gene can be obtained by introducing a desired antigen-specific T cell receptor gene into the pluripotent stem cell.
- T cells used for immune cell therapy obtained by the method of the present application are T cells having a single antigen specificity, so there is no worry of causing graft-versus-host reaction, and not only for autotransplantation but also for allogeneic transplantation. Can be used.
- the method of the present application is a method that cannot be predicted at all from the common sense that other cell transplantation of T cells is contraindicated.
- the problem in the conventional technical recognition can be solved unexpectedly, and the following effects can be obtained: 1) It is not necessary to prepare T cells for transplantation for each patient, and preparation is possible. 2) Can be processed after confirming the safety and quality of transplanted cells in advance. 3) Even if the HLA matches, the minor antigen does not match, and it is a nontransgenic transplant. After a certain period of time, it is rejected by the patient's immune reaction, and the transferred cells are not likely to become cancerous.
- the T cells for transplantation of the present application are obtained by a method comprising a step of introducing a desired antigen-specific T cell receptor gene (TCR gene) into pluripotent stem cells, the following effects are obtained: 1) The quality of the obtained T cells for transplantation is assured by introducing the TCR gene with guaranteed efficacy and safety. 2) The TCR gene insertion site can be identified, a safe clone can be confirmed and used, and the problem of canceration of transplanted cells can be avoided in advance. 3) When pluripotent stem cells obtained by inserting the TCR gene into pluripotent stem cells are differentiated into T cells, the introduced TCR is first expressed during the differentiation process, so that the cells are originally present (hereinafter referred to as endogenous). The TCR is not reconstructed, and unexpected reactions rarely appear.

- the TCR gene When the TCR gene is inserted using a vector as described above, it enters a site different from the TCR gene on the genome, but in other modes, it can be inserted into the TCR locus by “replacement”.
- a TCR gene When a TCR gene is inserted using a vector, iPS cells derived from somatic cells other than T cells are preferable. In the case of “replacement”, it is preferable to use T cell-derived iPS cells.
- the already reconstructed TCR ⁇ chain and TCR ⁇ chain genes can be replaced with the desired TCR ⁇ chain and TCR ⁇ chain genes, respectively, using genome editing technology or the like.
- the advantages of using this method are that 1) the time and level of expression of the introduced TCR can be close to that of the original TCR, so that high quality T cells can be produced, and 2) the genome is not damaged. is there.
- TCR-iPS cells obtained by introducing the TCR gene into iPS cells are induced to differentiate into T progenitor cells or mature T cells.
- Examples of the method for inducing differentiation into T cells include the method described in Timmermans et al., Journal of Immunology, 2009, 182: 6879-6888.
- T progenitor cell refers to a stage of a cell immediately before receiving positive selection / negative selection from a stage corresponding to a hematopoietic stem cell, which is the most undifferentiated cell among hematopoietic cells. To the equivalent of. T cell differentiation is described in Blood B111: 1318 (2008), NaturemmImmunology 11: 585 (2010).
- T precursor cells or mature T cells derived from TCR-iPS express the introduced TCR without reconstitution of the endogenous TCR. Therefore, safe treatment can be performed without causing an unexpected attack in immune cell therapy.
- the safety can be further improved by preventing the complete reconstitution of the endogenous TCR by deleting the Rag1 gene or the Rag2 gene at the iPS cell stage. Only one of the Rag1 gene and the Rag2 gene needs to be deleted. A method of simultaneously introducing SiRNA that suppresses the expression of endogenous TCR is also possible.

Description
A. 初期化技術を用いたクローニング法
自家移植を目的としたT細胞のクローニングの問題を解決する技術が提案されている。初期化の技術を用いて特異的TCR遺伝子の構造を有する幹細胞としてクローニングする方法である。具体的には核移植、iPS細胞化などによりT細胞から多能性幹細胞を作製する方法であり、特許出願もされている(WO2008/038579、WO2011/096482)。また、かかる方法についての論文は2010年、2013年に発表されている。

抗原特異的T細胞受容体(TCR)遺伝子を単離し、その遺伝子を患者の正常T細胞(多くのクローンの集合体)に発現させて患者の体に戻す(自家移植)という遺伝子治療の臨床試験が各地で行われている(Morgan R.A. et al, Science, 314:126. 2006)。この方法では患者の正常T細胞がもともと発現しているTCRを例えばsiRNAなどで発現を抑制し(Okamoto S et al, Cancer Res 69:9003, 2009)、特定のTCRのみが発現したT細胞を自家移植する。例えば、WT1抗原特異的T細胞受容体(TCR)遺伝子が単離されていて、WT1を発現するがんに対する遺伝子治療が行われている。
白血病などの血液系の腫瘍に対して行われる骨髄移植は、免疫細胞療法としての側面をもつ。すなわち、移植されたドナーの骨髄細胞の中に含まれるT細胞がレシピエントの白血病細胞を攻撃することが期待されている。効果を高めるためにドナーのT細胞だけを後に追加して投与する、ドナーリンパ球輸注法も知られている。また近年、所望の抗原に対するクローンとして増幅させたT細胞を輸注するという方法が報告された(Chapuis et al, Sci Transl Med, 5:174ra27, 2013)。
臍帯血移植後に免疫力が低下した患者にウイルス感染症が発症することがある。そのようなケースを対象に移植に用いたドナー臍帯血ではなく他の臍帯血中のウイルス特異的CTLを輸注するという方法が提案されている(Blood, 116: 5045, 2010)。類似の発想で、HLAがある程度一致しているが完全には一致しないようなCTLを移植するというアイデアの特許出願が出されている(WO2011/021503)。しかしながら、臍帯血は多数のT細胞クローン、すなわち多種類のTCRを有する細胞の集団であり、移植片対宿主病(GVHD)を起こす危険性を回避できない。
1)移植用T細胞を患者ごとに作製する必要がなく事前準備ができる、
2)事前に移植細胞の安全性および品質を確認した上での処理をすることができる、
3)たとえHLAが一致していたとしてもマイナー抗原は一致しない他家移植であり、一定の期間の後には患者の免疫反応によって拒絶され、移入した細胞ががん化する恐れがない。
1)効果並びに安全性が保障されたTCRの遺伝子を導入することにより、得られる移植用T細胞の品質が保証される。
2)TCR遺伝子挿入箇所を同定し、安全なクローンを確定して用いることができ、移植細胞のがん化の問題を予め回避できる。
3)多能性幹細胞へTCR遺伝子挿入して得られる多能性幹細胞をT細胞へ分化させる場合、分化過程で導入TCRが先に発現することから細胞が元々もっている(以下内因性と表記)TCRが再構成されず、想定外の反応が出現することがほとんどない。
導入する対象の細胞としては京都大学再生医科学研究所再生免疫学分野(日本国京都府京都市)にて作製されたLMP2-T-iPS細胞(クローンLMP2#1)を用いた。
導入したHLA-A2402拘束性を有するWT1 TCRは,大阪大学医学系研究科免疫造血制御学研究室(日本国大阪府吹田市)でクローニングされたB10を用いた(Anticancer Research 32(12); 5201-5209, 2012). このTCRはHLA-A2402拘束性にペプチドCMTWNQMNL(配列番号4)を認識する。
クローンとなるように増幅したWT1特異的CTLもしくはWT1-T-iPS細胞から誘導されたCTLからRNAを調整する。SMARTer RACE cDNA増幅キット(クロンテック社)を用いて完全長cDNAを得,これを鋳型とした。 TCRα鎖の3’側からのプライマー(CACAGGCTGTCTTACAATCTTGCAGATC(配列番号1))もしくはTCRβ鎖の3’側からのプライマー2種(CTCCACTTCCAGGGCTGCCTTCA(配列番号2)またはTGACCTGGGATGGTTTTGGAGCTA(配列番号3))を用い,PCR反応によってWT1-TCRの二本鎖cDNAを得た。得られた二本鎖cDNAをpTA2ベクター(東洋紡社、図1)に組み込み,細胞株に導入することでWT1 TCRの特異性などの検定を行った。
独立行政法人理化学研究所 バイオリソースセンター 細胞運命情報解析技術開発サブチーム(日本国茨城県つくば市)より提供されたCS-UbC-RfA-IRES2-Venusベクター(図2)を用い,GatewayシステムによりWT1-TCRを導入したCS-UbC-RfA-IRES2-Venus/WT1-TCRを作製した。
CS-UbC-RfA-IRES2-Venus/WT1-TCRをX-treamGENE9(ロシュ社)を用いてパッケージング細胞LentiX-293Tに導入した。翌日に培地交換を行い,2日目にレンチウィルスを含む培養上清を回収し,レンチウィルス上清として用いた。
LMP2-T-iPS細胞をTrypLE Select (ライフテクノロジーズ社)を用いて完全な単一細胞とする。遠心後,ペレットをレンチウィルス上清で懸濁し,32℃,3000rpmで1時間遠心し,LMP2-T-iPS細胞に感染させることでWT1-TCRをLMP2-T-iPS細胞に導入した。
感染後,iPS細胞用培地に懸濁し,フィーダー細胞上に播種した。WT1-TCRが導入されたLMP2-T-iPS(WT1-TCR/LMP2-T-iPS)細胞はベクターに含まれるVenusタンパク質の発現によって蛍光顕微鏡下で選択された。
1.2週間後にiPS細胞コロニーを目視により確認した。
2. 200ulチップによりコロニーを物理的に拾い上げた。
3. 各クローンを個別に樹立した。
各培地の組成を下記に示す。
0.1% ゼラチン/PBS溶液6mlを10cm培養ディッシュに入れ,37℃で30分以上静置する。コンフルエントになったOP9細胞をトリプシン/EDTA溶液で剥がし,1/4相当量をゼラチンコートした10cm培養ディッシュに播種した。培地はmedium Aを10mlとなるように加えた。
4日後に播種したOP9細胞培養ディッシュに新たにmedium Aを10ml加え,全量が20mlとなるようにした。
共培養に使用するOP9細胞の培地を吸引し,新しいmedium Aに交換する。またヒトiPS細胞培養ディッシュの培地も同様に吸引し,新しいmedium Aを10ml加える。EZ-passageローラーでヒトiPS細胞を切る。カットしたiPS細胞塊を200ulピペットマンでピペッティングすることで浮遊させ,目視でおおよそ600個のiPS細胞塊をOP9細胞上に播種した。
ヒトiPS細胞1クローンあたり3枚以上のディッシュを用い,継代するときには細胞を一度一つに合わせてから同じ枚数に再分配することでディッシュ間のばらつきを減らした。
ヒトiPS細胞塊が接着し分化し始めているかどうかを確認し,培地を新しいmedium A 20mlに交換した。
Day 5 (培地半量交換)
半量分の培地を新しいmedium A 10mlに交換した。
Day 9 (培地交換)
半量分の培地を新しいmedium A 10mlに交換した。
Day 13 (誘導した中胚葉細胞をOP9細胞上からOP9/DLL1細胞上への移しかえる)
培地を吸引し,HBSS(+Mg+Ca)で細胞表面上の培地を洗い流した。その後250U collagenase IV/HBSS(+Mg+Ca) 溶液10mlを加え,37℃で45分間培養した。
Collagenase溶液を吸引し,PBS(-)10mlで洗い流した。その後5mlの0.05%トリプシン/EDTA溶液を加え,37℃で20分培養した。培養後,細胞が膜状に剥がれてくるのでピペッティングにより物理的に細かくした(接着細胞同士を離すため)。ここに新しいmedium Aを20ml加え,さらに37℃で45分間培養する。培養後、浮遊細胞を含む上清を,100μmのメッシュを通して回収した。4℃,1200rpmで7分間遠心し、ペレットを10mlのmedium Bに懸濁させた。このうち1/10をFACS解析用にとりわけ、残りの細胞を新たに用意したOP9/DLL1細胞上に播種した。複数枚のディッシュから得た細胞をプールした場合,元々の枚数と同じ枚数になるように再分配して細胞を播き直した。
次いで細胞をOP9/DLL1細胞上に播種した。この工程において,CD34lowCD43+細胞分画の細胞のソーティングは行わない。この分画をソーティングした場合,得られる細胞数が減少してしまうことやソーティングによる細胞へのダメージから,ソーティングしなかった場合に比べてT細胞への分化誘導効率が落ちることがある。
OP9/DLL1細胞に緩く接着している細胞を,穏やかに複数回ピペッティングし,100μmのメッシュを通して50mlコニカルチューブに回収した。4℃,1200rpmで7分間遠心し,ペレットを10mlのmedium Bに懸濁させる。これらの細胞を新たに用意したOP9/DLL1細胞上に播種した。
Day 23 (細胞の継代): 血液細胞コロニーが見え始める。
OP9/DLL1細胞に緩く接着している細胞を,穏やかに複数回ピペッティングし,100μmのメッシュを通して50mlコニカルチューブに回収する。4℃,1200rpmで7分間遠心し,ペレットを10mlのmedium Bに懸濁させた。これらの細胞を新たに用意したOP9/DLL1細胞上に播種した。
Day 30 (細胞の継代):
OP9/DLL1細胞に緩く接着している細胞を,穏やかに複数回ピペッティングし,100μmのメッシュを通して50mlコニカルチューブに回収した。4℃,1200rpmで7分間遠心し,ペレットを10mlのmedium Bに懸濁させる。これらの細胞を新たに用意したOP9/DLL1細胞上に播種した。
Day 37 (細胞の継代):
OP9/DLL1細胞に緩く接着している細胞を,穏やかに複数回ピペッティングし,100μmのメッシュを通して50mlコニカルチューブに回収した。4℃,1200rpmで7分間遠心し,ペレットを10mlのmedium Bに懸濁させる。これらの細胞を新たに用意したOP9/DLL1細胞上に播種した。
Day 44: (CD4+CD8+T細胞の確認、CD8 SP細胞の誘導開始)
T細胞が誘導されているかどうかを確かめるために抗CD4抗体,抗CD8抗体を用いてFACS解析した。CD4+CD8+T細胞の生成が確認された。
ここで抗CD3/28抗体をhuIL-2と供に加える.24穴プレートに新たにOP9/DLL1細胞を用意しておき,CD4+CD8+T細胞を含んだT細胞を3x105個/穴となるように播種した.ここに抗CD3抗体(50ng/ml),抗CD28抗体(2ng/ml), huIL-2 (200U/ml)を添加した.
Day 50: (CD4-CD8+細胞が現れる)
抗CD3抗体による刺激後6日目には,成熟CD8SP細胞が生成した.生成した細胞をWT1-テトラマーと抗CD3抗体で染色した(図3)。導入したWT1-TCRを発現するT細胞が生成しているのが確認された。
導入する対象の細胞として京都大学再生医科学研究所再生免疫学分野(日本国京都府京都市)にて健常人末梢血単球より作製されたHLAハプロタイプホモ型iPS細胞を用いた。
このiPS細胞のHLA型はHLA-A*33:03; B*44:03; C*140:3; DRB1*1302
のホモ接合型である。
導入したHLA-A0201拘束性を有するWT1特異的TCR遺伝子は,大阪大学医学系研究科免疫造血制御学研究室(日本国大阪府吹田市)でクローニングされたOpt3E2を用いた.このTCRが認識するペプチド配列はRMFPNAPYL(配列番号5)である。
2. 遺伝子導入後のiPS細胞をディッシュに播種し、クローナルなコロニーとして培養した。図5は培養1週間後のコロニーを示しており、遺伝子が導入されたコロニーは蛍光色素陽性コロニーとして写っている。すなわち、HLA-A0201拘束性WT1特異的TCR遺伝子が導入されたiPS細胞のクローニングできたことを示している。この後、この陽性コロニーをピックアップして分離した。
導入する対象の細胞としては実施例2と同じく京都大学再生医科学研究所再生免疫学分野(日本国京都府京都市)にて健常人末梢血単球より作製されたHLAハプロタイプホモ型iPS細胞を用いた。
導入したWT1特異的TCR遺伝子は,大阪大学医学系研究科免疫造血制御学研究室(日本国大阪府吹田市)でクローニングされたたクラスII拘束性WT1特異的TCR遺伝子、Clone KとClone 10を用いた。CloneKはHLA-DRB1*0405拘束性、Clone10はHLA-DPB1*0501拘束性で、認識するペプチド配列はWT1-332(KRYFKLSHLQMHSRKH(配列番号6))である(Microbiol Immunol 52: 591-600, 2008)。
導入する対象の細胞としては実施例2と同じく京都大学再生医科学研究所再生免疫学分野(日本国京都府京都市)にて健常人末梢血単球より作製されたHLAハプロタイプホモ型iPS細胞を用いた。
導入したWT1特異的TCR遺伝子は,京都大学再生医科学研究所再生免疫学分野(日本国京都府京都市)にてClonn#9とClone#3-3からクローニングされたクラスI拘束性WT1特異的TCR遺伝子である。
