Definitions
- the present invention relates to modified adeno-associated virus vectors.
- AAV1-10 adeno-associated virus
- AAV adeno-associated virus
- AAV greatly differs in infection tropism depending on the type of serotype, and it is necessary to select an optimal vector according to target cells for target gene therapy or genome editing therapy.
- existing AAV vectors do not always exhibit optimal tropism for infection of target cells. Since the infection tropism of AAV varies depending on the amino acid sequence of the capsid region, it is possible to develop a vector with optimal infection tropism by modifying the same sequence. From this point of view, modified adeno-associated virus vectors for gene therapy and genome editing therapy for various diseases are being studied.
- Wild serotypes such as AAV1 and AAV2 have been used as candidates for gene therapy for the inner ear, but recently capsid-modified vectors such as AAV-ANC80L65 (Patent Document 1) have also been developed. These strains allow gene transfer to the inner ear, but have different infection tropisms.
- AAV1 has the ability to infect cochlear outer cells (external spiral groove cells), but has weak ability to infect other epithelial cells.
- AAV2 has a high ability to infect cochlear hair cells, but a weak ability to infect other epithelial cells.
- the AAV-ANC80L65 vector which enhances the ability of AAV2 to infect the inner ear, has the ability to infect some outer hair cells in addition to the ability of AAV2 to infect inner hair cells.
- Application to gene therapy for GJB2 mutant deafness (characterized by defective formation of gap junctions), which is the most common type of hereditary deafness, due to its low ability to infect external and cochlear internal cells (inner spiral groove cells) is difficult.
- infection is directed to epithelial cells represented by inner ear cells, interstitial cells, nerve cells, retinal cells, lens cells, cancer cells, skin cells, and cells expressing gap junctions and constituent connexin molecules.
- a modified AAV vector with excellent performance has not yet been developed. Therefore, the object of the present invention is to infect epithelial cells typified by inner ear cells, interstitial cells, nerve cells, retinal cells, lens cells, cancer cells, skin cells, and cells expressing gap junctions and connexin molecules.
- An object of the present invention is to provide a modified AAV vector with excellent directivity.
- the present inventors first examined the infection tropism of AAV serotypes to inner ear epithelial cells, and found that AAV1, AAV6, AAV7, and AAV8 attack inner ear epithelial cells, particularly supporting cells that form inner ear gap junctions. It was found that the tropism of infection was high.
- Patent Document 1 It has a different infection tropism from the described AAV-ANC80L65 vector and other wild-type AAVs, and found that it becomes a vector with high infection tropism to epithelial cells typified by inner ear epithelial cells, and completed the present invention. .
- a modified adeno-associated virus vector in which some amino acid residues of the adeno-associated virus capsid sequence are substituted with other amino acid residues, and alignment with the amino acid sequence of the AAV1 capsid sequence of SEQ ID NO: 1 at (1) position 129 (Leu), (2) position 268 (Ser), (3) position 447 (Asn), (4) position 470 (Gly), (5) position 472 (Ser), (6) 473
- One or more amino acid residues selected from position (Val), (7) position 502 (Thr) and (8) position 531 (Glu) or the amino acid residue at a position corresponding thereto is replaced with another amino acid residue modified adeno-associated virus vector.
- the epithelial cells are epithelial cells selected from inner ear epithelial cells, intestinal epithelial cells, retinal cells, skin cells, renal cells, airway epithelial cells, nerve cells, myocardial cells, and cancer cells in which Connexin expression is involved.
- a gene selected from GJB2 gene, SLC26A4 gene, TMC1 gene, TMC2 gene and Atoh1 gene which can be applied to gene therapy or genome editing therapy for hereditary diseases, tissue damage and cancer
- [7] A gene therapy drug or genome editing drug for treatment of genetic disease, tissue damage or cancer in target cells, containing the modified adeno-associated virus vector of [6].
- [8] Use of the modified adenovirus-associated vector of [6] for the production of a gene therapy drug or genome editing drug for treatment of genetic disease, tissue damage or cancer in target cells.
- the modified adenovirus-associated vector of [6] for use in treating genetic diseases, tissue damage or cancer in target cells.
- a method for treating a genetic disease, tissue damage or cancer in a target cell which comprises administering the modified adeno-associated virus vector of [6].
- a candidate modified adeno-associated virus vector is obtained by substituting any one or more amino acid residues selected from (a) below with other amino acid residues in the amino acid sequence of the capsid sequence of the reference adeno-associated virus vector.
- the amino acid substitution is Leu129Phe, Ser268Thr, Asn447Ser, Gly470Thr, Ser472Ala, Val473Asn, Thr502Ala and Glu531Lys
- the production method according to [12] which is one or more selected from [15] The production method of [12], wherein the target cells are inner ear, skin, heart, eye, brain, upper gastrointestinal tract, lower gastrointestinal tract or kidney cells.
- Target cells are inner ear epithelial cells, intestinal epithelial cells, airway epithelial cells, retinal cells, lens cells, skin cells, kidney cells, airway epithelial cells, nerve cells, cardiomyocytes, stromal cells, and involved in Connexin expression

- Example 5 Gene Transfer into Cultured Cochlear Organs Derived from Deafness Model Animals Using cultured cochlear organs of GJB2-deficient mice, wild-type AAV6 and AAV-sia6.8 carrying the GJB2 gene and the EGFP gene were infected.
- mice Four-day-old mice were experimentally killed under anesthesia and the cochlea was removed from the temporal bone.
- the cochlear shaft was removed from the cochlea and the stria vascularis stripped from the organ of Corti.
- Organs of Corti were transferred to 8-well chamber slides and cultured overnight (5% CO2 atmosphere, 37°C). The medium was then changed to medium containing 4 ⁇ l of AAV solution per 100 ⁇ l (2.05 ⁇ 10 13 GC/mL). After an additional 5 days of culture, the organ of Corti was treated with 4% paraformaldehyde and fixed.
- FIG. 8 shows the results of image analysis of the EGFP-positive area ratio in the outer spiral groove cell region (OSC) and the region containing outer hair cells and Ditellus cells (OHC+DC).
- AAV-sia6.8 has a higher positive area rate than wild-type AAV6 in both the outer spiral groove cell region (OSC) and the region containing outer hair cells and Ditellus cells (OHC + DC). , showed that gene transfer was possible in a wide range of inner ear epithelial cells with high efficiency.
- Example 6 Gene therapy (repair of gap junctions in inner ear epithelial cells induced from iPSC cells derived from hearing impaired patients) Differentiation of inner ear epithelial cells was induced from induced pluripotent stem cells (iPSCs) established from patients with severe hearing loss due to abnormalities in the GJB2 gene and subjects with normal hearing. Inner ear epithelial cells were infected with AAV-sia6.8 carrying the wild-type GJB2 gene, and gap junction repair was performed by expression of connexin 26 (CX26).
- iPSCs induced pluripotent stem cells
- iPSC strain (201B7) derived from a normal hearing subject was obtained from the RIKEN BioResource Center Cell Bank.
- the iPSC line (cell line name: JUFMDOi005-A) derived from a patient with hearing loss is described in the present inventors' academic paper ("Generation of two induced pluripotent stem cell lines from PBMCs of siblings carrying c.235delC mutation in the GJB2 gene associated with sensorineural hearing loss”, Stem Cell Research, Volume 47, August 2020, 101910).
- iPSCs were suspended in Stem Fit medium supplemented with 20 ⁇ m Y27632 and seeded in 96-well plates at 9000 cells/well. After 2 days of incubation (37°C, 5% CO 2 ), gfCDM medium supplemented with 2% matrigel (Ham's F12 GlutaMax/IMDM GlutaMax (1:1) (Gibco), 1 % Chemically defined lipid concentrate (Gibco), 0.5 Cell aggregates were transferred to 96-well plates containing 100 ⁇ l of % BSA (Sigma), 15 ⁇ g/ml Transferin (Sigma), 450 ⁇ M 1-Thioglycerol (Sigma)) and further incubated.
- Stem Fit medium supplemented with 20 ⁇ m Y27632 and seeded in 96-well plates at 9000 cells/well.
- gfCDM medium supplemented with 2% matrigel (Ham's F12 GlutaMax/IMDM GlutaMax (1:1) (G
- TRIC inner ear-derived feeder cells
- Cochlear tissue consists of the organ of Corti, the basement membrane, and the lateral wall, and is mainly composed of supporting cells, hair cells, cochlear nerve fiber cells, and other cells of the basement membrane.
- TRICs were obtained by exposing cochlear tissue to trypsin and screening for trypsin-resistant cells. These cells were maintained under growth medium (DMEM-GlutaMax (Gibco), 10% FBS (Gibco)).
- CX26 connexin 26
- CX30 GJB6 gene product
- inner ear gap junctions were unclear and insufficiently formed, and the expression intensity of CX26 relative to CX30 was reduced to about 25%.
- the expression intensity of CX26 relative to CX30 was restored to about 50% (GJB2-235delC + AAV-GJB2WT), and gap junctions were repaired. I was able to confirm that there is.
- Example 7 Gene therapy (regeneration of hair cells) Infection experiments with AAV-sia6.8 harboring the protein atonal homolog 1 (Atoh1) gene were carried out using mouse cultured cochlear organs. It is known that the transcription factor Atoh1 induces the differentiation of supporting cells into hair cells when the gene is introduced into the supporting cells. As shown in FIG. 11, hair cell-like cells appeared in a region different from the hair cell region (the region surrounded by the dotted line in FIG. 11 (A)) (FIG. 11 (B) (C ) arrow). FIG. 11(B) is an enlarged view of the region enclosed by the dotted line in FIG. 11(A). It was demonstrated that AAV-sia6.8 can be effectively used to regenerate hair cells that have been lost due to noise-induced deafness or the like.
- Example 8 Gene therapy (hearing recovery in deafness model animals) Hearing ability of GJB2-deficient mice (3-4 weeks old) was measured based on auditory brainstem response (ABR) (preoperative hearing ability). Under anesthesia, two small holes were made in the lateral semicircular canal of mice using a dental drill. A capillary tube was inserted into one of the holes, and 10-12 ⁇ l of AAV-sia6.8 solution (about 1 ⁇ 10 13 GC/ml) loaded with the wild-type GJB2 gene was added to the endolymph at a rate of 3 ⁇ l/min. injected. One and two weeks after surgery, hearing was measured based on the auditory brainstem response (ABR) (post-operative hearing).
- ABR auditory brainstem response
- ABR was measured by placing stainless steel needle electrodes at the apex and ventrolateral side of the left and right ears, using waveform storage and stimulation control of the Scope software of the Power Laboratory system (PowerLab 4/25; AD Instruments). Electroencephalography was performed with an extracellular amplifier AC PreAmplifier (model P-55; Astro-Med). Acoustic stimulation was provided by a coupler-type speaker (model ES1spc; Bio Research Center). Thresholds were determined based on a series of responses with varying intensity at 5 dB intervals at frequencies of 8, 20, and 40 kHz.
- Preoperative and postoperative ABR thresholds and waveforms are shown in Figures 12 and 13, respectively.
- Two weeks after the operation (AAV-Sia6.8-CX26 2W), the threshold of ABR at high wavelengths (20kHz, 40kHz) decreased compared to before the operation (Pre-operation), and a significant improvement in hearing was observed. (See FIG. 12).
- 2 weeks after the operation (2W post-infection) a response was confirmed even to weak sound pressure, which was not responsive before the operation (CX26cKO pre-injection) (see Fig. 13).
- Example 9 Cell-targeted gene transfer using a promoter Promoter 2 (gene sequence of 760 bp upstream from the transcription initiation point of the human GJB2 gene, SEQ ID NO: 12) was introduced into AAV-sia6.8, and the GJB2 gene and the EGFP gene were introduced. was loaded to infect cultured cochlear organs of GJB2-deficient mice. As shown in FIG. 14, the formation of gap junctions accompanied by the expression of EGPF (green) and the expression of connexin 26 (red) was confirmed in outer spiral groove cells (OSC), which are supporting cells. No infection of outer and inner hair cells (OHC and IHC) was observed. This result indicated that AAV-sia6.8 can be effectively used for cell-targeted gene transfer (gene transfer targeting supporting cells in this example) by introducing an appropriate promoter. .
- promoter Promoter 2 gene sequence of 760 bp upstream from the transcription initiation point of the human GJB2 gene, SEQ ID NO:
- Example 10 Introduction of additional amino acid substitutions into modified AAV and evaluation of infection tropism 2 Similar to Example 2, a Thr268Ser variant of AAV-sia6.8 was constructed. At amino acid position 268 of AAV-sia6.8, Ser in wild-type AAV6 is replaced with Thr. Therefore, the Thr268Ser variant of AAV-sia6.8 is a modification that restores the wild-type Ser to the amino acid at position 268.
- FIG. 15 and FIG. 16 show the fluorescence images of EGFP and the results of calculating the EGFP-positive area ratio by image analysis.
- the Thr268Ser variant of AAV-sia6.8 (AAV-Sia-T268S) has improved infection tropism to inner ear cells compared to AAV-sia6.8, especially in outer spiral groove cells (OSC). improvement was remarkable.

各種血清型のAAVベクター(GeneCapoeia社、AAVPrimeTM Adeno-associated virus(AAV) Serotype Testing Kit Plus,Cat. No.AA321)を用いて、羊土社 実験医学別冊 決定版 ウイルスベクターによる遺伝子導入実験ガイド AAVベクターを用いた内耳への遺伝子治療 Page159-166(2020.11)に記載の方法によって、内耳上皮細胞への感染指向性について検討した。
AAVベクターには、コネキシン26をコードするGJB2遺伝子を配列番号11-13のいずれかの塩基配列を含んでなるプロモーター(それぞれプロモーター1、プロモーター2、プロモーター3と称する)の制御下に組み込んだ。
生後4日齢のマウス(C57BL/6J系)より内耳を摘出し、感覚上皮を含む組織を8ウェルチャンバースライド(Matsunami, Cat. No.SCS-N38)上でDMEM培地中で1晩培養した。翌日に各血清型AAV(AAV1-10、5×108-5×109GC)を添加した。4-6日間培養し、4%パラホルムアルデヒドで固定後に抗コネキシン26抗体(Thermofisher Scientific. Cat. No.51-2800)による免疫蛍光染色を行い、AAVのレポーター遺伝子であるEGFPの緑色蛍光と共に蛍光顕微鏡で観察し、EGFP陽性細胞とコネキシン26によるギャップ結合を形成する細胞を計測した。
その結果、図2及び図3に示すように、AAV1、AAV6、AAV7及びAAV8は、内耳細胞、特にギャップ結合を形成する支持細胞への感染指向性が他の血清型に比べて高いことが判明した。
また、プロモーター1(ヒトGJB2遺伝子の転写開始点から上流の1065bpの遺伝子配列)、プロモーター2(ヒトGJB2遺伝子の転写開始点から上流の760bpの遺伝子配列)及びプロモーター3(ヒトGJB2遺伝子の転写開始点から上流の260bpの遺伝子配列)は、内耳支持細胞及び内耳線維細胞での各種タンパク質発現に適していた。コネキシン26の発現強度に基づいてプロモーター活性を評価したところ、活性が高い順にプロモーター1、プロモーター2、プロモーター3であった。
Nat Methods 6,343-345(2009)に記載のPCRプライマーに変異を加えるジーンターゲティング手段を用いて、カプシド配列のアミノ酸配列に種々のアミノ酸置換を導入したベクターを作成した。なお。改変ベクターには、GJB2遺伝子とレポーター遺伝子(EGFP遺伝子)も導入した。
得られた改変ベクターの形質導入効率、感染指向性の変化を表1に示す。
その結果、AAV1のカプシド配列に対して、Ser268Thr、Asn447Ser、Gly470Thr、Ser472Ala、Val473Asn及びThr502Alaの置換を有する改変型AAVベクター(AAV-sia1.8:配列番号15)は、AAV1が有毛細胞(内有毛細胞、外有毛細胞)にはほぼ感染しないのに対し、外有毛細胞への特異性が高く、内耳上皮細胞群の中で外有毛細胞への感染能が最も高く80~100%の感染効率となることがわかった。
また、AAV6のカプシド配列に対して、Ser268Thr、Asn447Ser、Gly470Thr、Ser472Ala、Val473Asn及びThr502Alaの置換を有する改変型AAVベクター(AAV-sia6.8:配列番号14)においては、前記AAV-sia1.8と同様に外有毛細胞への高い感染能を持つ。外有毛細胞への特異性、感染指向性はAAV-sia1.8より弱いが、前記AAV-sia1.8より広範囲の内耳上皮細胞群に感染する能力を持つことがわかった。

実施例2と同様にして、AAV-sia1.8のGlu531Lys改変体、及びAAV-sia1.8のLeu129Phe改変体を作成した。
AAV-sia1.8のGlu531Lys改変体(配列番号16)は、AAV1と比して外有毛細胞と支持細胞への感染性が強く、支持細胞においては面積の大きいギャップ結合複合体を多数形成する。一部の内有毛細胞へも感染する。
また、AAV-sia1.8のLeu129Phe改変体(配列番号17)も同様に、AAV1と比して外有毛細胞と支持細胞への感染性が強く、支持細胞においては面積の大きいギャップ結合複合体を多数形成する。一部の内有毛細胞へも感染する。
難聴モデル動物(GJB2欠損マウス)の内耳上皮にAAV sia1.8でGJB2(GJB2及びEGFP導入済み)を導入した染色像を図4に示す。赤が導入したGJB2遺伝子によるコネキシン26タンパク質を示す。緑がEGFPのレポーターを示す。外有毛細胞において感染を示すEGFP発現が特異的に強く、その他の内有毛細胞や支持細胞などへの感染を示すEGFP発現およびコネキシン26の発現が少ない。
GJB2欠損マウスの培養蝸牛器官を用いて、GJB2遺伝子とEGFP遺伝子を搭載した野生型AAV6及びAAV-sia6.8の感染実験を行った。
外らせん溝細胞の領域(OSC)と、外有毛細胞とダイテルス細胞を含む領域(OHC+DC)におけるEGFP陽性面積率を画像解析した結果を図8に示す。AAV-sia6.8は、野生型AAV6に比して、外らせん溝細胞の領域(OSC)と、外有毛細胞とダイテルス細胞を含む領域(OHC+DC)のいずれにおいても陽性面積率が高く、内耳上皮細胞の広範囲の細胞に高い効率で遺伝子導入が可能であることが示された。
GJB2遺伝子の異常による重度難聴患者と健聴者から樹立された人工多能性幹細胞(iPSC)から内耳上皮細胞を分化誘導した。内耳上皮細胞に対して、野生型GJB2遺伝子を搭載したAAV-sia6.8を感染させ、コネキシン26(CX26)の発現によるギャップ結合の修復を行った。
難聴患者由来のiPSC株(細胞株名:JUFMDOi005-A)は、本発明者らの学術論文(”Generation of two induced pluripotent stem cell lines from PBMCs of siblings carrying c.235delC mutation in the GJB2 gene associated with sensorineural hearing loss”, Stem Cell Research, Volume 47, August 2020, 101910)に記載の方法によって作成された。
TRICは、10週齢のマウスから採取した蝸牛組織から調製した。蝸牛組織は、コルチ器官、基底膜、側壁からなり、主に支持細胞、有毛細胞、蝸牛神経線維細胞、その他の基底膜の細胞から構成される。蝸牛組織をトリプシンに曝露し、トリプシン耐性細胞をスクリーニングすることによってTRICを得た。これらの細胞を増殖培地(DMEM-GlutaMax (Gibco), 10% FBS (Gibco))下で維持した。
マウスの培養蝸牛器官を用いて、プロテインアトナールホモログ1(Atoh1)遺伝子を搭載したAAV-sia6.8の感染実験を行った。転写因子Atoh1は、支持細胞に遺伝子導入されると、支持細胞を有毛細胞へ分化誘導させることが知られている。図11に示すように、有毛細胞(Hair cells)領域とは異なる領域(図11(A)において点線で囲った領域)に、有毛細胞様細胞が出現した(図11(B)(C)の矢印参照)。図11(B)は、図11(A)において点線で囲った領域を拡大したものである。騒音性難聴等によって有毛細胞が欠損した場合に有毛細胞を再生するために、AAV-sia6.8を有効に利用できる可能性が示された。
GJB2欠損マウス(3-4週齢)の聴力を聴性脳幹反応(ABR)に基づき測定した(術前聴力)。麻酔下でマウスの外側半規管(lateral semicircular canal)の2箇所に歯科用ドリルを用いて小孔を設けた。一方の孔にキャピラリーチューブを挿入して外リンパ液(endolymph)へ10-12μlの野生型GJB2遺伝子を搭載したAAV-sia6.8溶液(約1×1013GC/ml)を3μl/minの速度で注入した。手術後1週間及び2週間後に、聴力を聴性脳幹反応(ABR)に基づき測定した(術後聴力)。
プロモーター2(ヒトGJB2遺伝子の転写開始点から上流の760bpの遺伝子配列、配列番号12)をAAV-sia6.8に導入し、GJB2遺伝子とEGFP遺伝子を搭載して、GJB2欠損マウスの培養蝸牛器官に感染させた。図14に示すように、支持細胞である外らせん溝細胞(OSC)でEGPFの発現(緑)と、コネキシン26の発現(赤)を伴うギャップ結合の形成が確認できた。外有毛細胞及び内有毛細胞(OHC及びIHC)への感染はみられなかった。この結果により、AAV-sia6.8は、適切なプロモーターを導入することによって、細胞標的化遺伝子導入(本実施例では支持細胞を標的とした遺伝子導入)に有効に用いられ得ることが示された。
実施例2と同様にして、AAV-sia6.8のThr268Ser改変体を作成した。
AAV-sia6.8の268位のアミノ酸は、野生型AAV6でのSerがThrに置換されている。したがって、AAV-sia6.8のThr268Ser改変体は、268位のアミノ酸を野生型のSerに戻す改変となる。
