專利名稱:一種靶向融合防齲dna疫苗及制備方法
技術領域:
本發明屬于口腔預防醫學技術領域,更具體涉及一種編碼人細胞毒性T淋巴細胞抗原4信號肽、胞外區的序列和Igγ1鉸鏈區、恒定區融合基因以及變形鏈球菌表面蛋白抗原基因和葡糖基轉移酶基因的包含新型載體的DNA防齲疫苗,本發明還涉及一種所述的靶向融合防齲DNA疫苗的制備方法。
背景技術:
齲病是一種嚴重危害人類口腔和全身健康的口腔常見病、多發病。因齲齒造成的功能喪失、炎癥、疼痛以及牙源性病灶所致臟器疾病可嚴重影響生活質量,降低人口健康素質,給社會帶來巨大危害。齲病是細菌感染性疾病,而變形鏈球菌(下稱變鏈菌,Streptococcus mutans)是主要的致齲菌。變鏈菌能夠與牙面緊密粘附并定植于牙面,產生酸性代謝產物,引起牙齒脫礦最終導致齲齒。
在變鏈菌致齲機制中變鏈菌與牙面的粘附是其致齲的首要條件,這個過程主要是由變形鏈球菌的重要致齲毒力因子表面蛋白(surface protein antigen,PAc)和葡糖基轉移酶(glucosyltransferaes,GTFs)介導的。PAc蛋白中富含丙氨酸的A區和富含脯氨酸的P區為主要的粘附功能區和免疫活性區,PAc位于變鏈菌的表面,介導了細菌與牙面獲得性膜的粘附。GTFs包含有兩個免疫活性區和功能區催化功能區(catalytic region CAT)和葡聚糖結合區(glucan binding region GLU),能夠合成葡聚糖,使變鏈菌憑借能夠與葡聚糖緊密結合的菌體表面結合型葡糖基轉移酶和葡聚糖結合蛋白與牙面更加緊密結合。變形鏈球菌主要合成三種GTFsGTF-I、GTF-SI、GTF-S,其中GTF-I主要合成以α-1,3糖苷鍵為主的水不溶性葡聚糖,其編碼基因為gtfB。
Saito等將PAc與佐劑霍亂毒素A亞單位一起通過粘膜途徑免疫小鼠誘導了唾液中產生抗PAc-IgA抗體,減少了小鼠口腔中變形鏈球菌的數目,而且免疫小鼠后,可以顯著降低口腔變鏈菌的聚集。說明PAc和霍亂毒素A亞單位復合體有望成為有效的粘膜防齲疫苗(Saito,M.,S.Otake,et al.2001.Protective Immunityto Streptococcus mutans Induced by Nasal Vaccination with Surface Protein Antigenand Mutant Cholera Toxin Adjuvant.J Infect Dis 183(5)823-826.)。宋長征等根據變形鏈球菌葡糖基轉移酶的葡聚糖結合區和蔗糖結合區(催化區)的保守氨基酸序列設計了27個氨基酸短肽,與弗氏佐劑混合后免疫機體后可有效誘導抗體產生,其免疫血清不僅拮抗GTF酶活性,而且明顯抑制了體外變鏈菌與試管壁的黏附能力(宋長征,趙建等,葡糖基轉移酶合成肽疫苗的免疫原性研究,中華口腔醫學雜志,2002,37(60)459-462)。Jespersgaard克隆表達了gtfB基因中的催化活性區(CAT)和葡聚糖結合區(GLU),分別免疫兔后,所獲得的抗CAT抗體能明顯抑制了變形鏈球菌和茸毛鏈球菌的GTFS合成水不溶性葡聚糖,而抗GLU抗體顯示了較抗CAT抗體更強的抑制變形鏈球菌的GTFS合成水不溶性葡聚糖的能力。這可能與GLU的重復序列特性增加了與抗體的結合能力和抗CAT抗體不易進入葡糖基轉移酶的催化區域有關。(Jespersgaard,C.,G.Hajishengallis,T.E.Greenway,D.J.Smith,M.W.Russell,and S.M.Michalek.1999.Functionaland immunogenic characterization of two cloned regions of Streptococcus mutansglucosyltransferase I.Infect Immun 67810-6.)。Zhang等用研制的包含變形鏈球菌表面蛋白抗原的SBR區和葡糖基轉移酶的GLU區的融合蛋白疫苗免疫小鼠,并與單獨使用SBR或GLU蛋白相比較,結果融合蛋白增強了粘膜免疫對SBR和GLU的應答,并且增強了系統免疫對SBR的反應強度(Zhang P,JespersgaardC,Lamberty-Mallory L.Enhanced immunogenicity of a genetic chimeric proteinconsisting of two virulence antigens of Streptococcus mutans and protection againstinfection.Infect.Immun.2002,70(12)6779-6787,)。
然而以上的各種防齲多肽疫苗存在許多不足之處,首先是這些多肽制備純化困難,一般需耗時數周且費用昂貴,保存需要特殊條件;其次,多肽防齲疫苗刺激機體產生有效的免疫反應的能力較差,常需添加各種對人體有害的免疫佐劑;多肽防齲疫苗與其它多肽疫苗一樣,誘導特異性免疫反應的持續時間一般較短,需反復多次接種才能達到較滿意的效果;另外多肽疫苗一般不能誘導嬰幼兒產生免疫反應。(Kowalczyk DW,Ertl HCJ.1999.Immune responses to DNA vaccines.CMLS,Cell.Mol.Life Sci.,55751-770)。
Fan(樊明文)等學者將編碼變形鏈球菌表面蛋白PAc的A區和P區基因克隆至真核表達載體pCI中,構建了防齲DNA疫苗pCIA-P,免疫大鼠,可以在血清和唾液中檢測到特異性抗體,同時證明能有效防齲(Fan MW,Z.BianZ.X.Peng et al.DNA Vaccine Encoding Streptococcus mutans Surface ProteinProtected Gnotobiotic Rats From Caries.J.Dent.Res.2002,81(11)784-787)。其后,為了提高DNA疫苗的免疫效能,將擴增出的編碼變形鏈球菌GS-5株葡糖基轉移酶GTF-I的基因gtfB的葡聚糖結合區的序列GLU克隆到真核表達質粒pCIA-P中獲得pGLUA-P融合防齲DNA疫苗(賈榮,樊明文,邊專等,融合防齲DNA疫苗pGLUA-P的構建及其細胞表達研究。中華口腔醫學雜志.2002,37(6)456-458)。動物實驗證實防齲效果優于只編碼一種毒力因子的防齲DNA疫苗pCIA-P(賈榮,樊明文,邊專等。GTF-PAc融合防齲DNA疫苗研究(III)pGLUA-P免疫定菌鼠防齲研究。口腔醫學縱橫雜志2002;18(1)3)。但是,防齲DNA疫苗和其他DNA疫苗一樣依舊面臨如何提高免疫效能的問題。
CTLA4(cytotoxic T lymphocyte-associated antigen 4,CTLA4),又稱CD152,是免疫球蛋白超家族的一員。它主要表達于活化的T細胞表面,亦可表達于CTL細胞,是CD4+T細胞免疫應答的重要調節因子,起免疫負調節作用。CTLA4結構基因包括四個外顯子,分別編碼先導序列、胞外區、跨膜區及胞漿區四個獨立的功能區,其胞外區包含一個Ig的V樣功能區,側翼與兩個疏水區相接,其中一個可以將CTLA4錨定在細胞膜上。研究表明CTLA4與表達于抗原遞呈細胞(APC)表面的CD80和CD86分子有很強的結合能力,是另一配體CD28的10~100倍(Ostrov DA,Shi W,Schwartz JCD,et al.Structure of Murine CTLA-4 andits role in modulating T cell responsiveness.Science,2000,290(27)816~819)。1998年澳大利亞學者Boyle等研究了結合有CTLA4基因片段的DNA疫苗并免疫小鼠,2周后測得特異性抗體水平比對照組高達10000倍(Boyle JS,Brady JL,LewAM.,Enhanced responses to a DNA vaccine encoding a fusion antigen that is directedto sites of immune induction.Natrue,1998,392(26)408-411)。其原因可能為CTLA4定向引導抗原與APC表面的B7分子結合,促進了APC攝取抗原,而APC在攝取抗原之后,自身被激活,表達了更多的B7分子,從而使更多的抗原被DC攝取、加工,起到了放大免疫反應的作用。因此,本研究小組為了進一步增強防齲DNA疫苗的免疫原性,提高免疫防齲效果,把人的細胞毒淋巴細胞相關抗原4(cytotoxic T lymphocyte-associated antigen 4,CTLA4)基因克隆到變形鏈球菌PAc和GTFs抗原基因的前端,構建了靶向融合防齲DNA疫苗pGJA-P,使在體內所翻譯的蛋白質能夠在CTLA4的引導下,與誘導免疫反應的關鍵細胞APC表面的配體分子B7分子結合從而提高免疫效能(郭繼華,樊明文,邊專等,靶向融合防齲DNA疫苗的構建與細胞表達,中華口腔醫學雜志。2003,38282-284)。經粘膜途徑免疫兔,比非靶向融合防齲DNA疫苗增強了誘導血清及唾液特異性抗體的能力(賈榮,樊明文,郭繼華等,靶向融合防齲DNA疫苗pGJA-P免疫兔的實驗研究,中華口腔醫學雜志。2004,3972-75)。
但是該疫苗的載體pCI質粒含有氨卞青霉素抗性基因,不符合DNA疫苗的載體骨架有關要求。pVAX1是美國Invitrogen公司根據美國藥品食品管理局(FDA)的要求,專門為DNA疫苗設計的真核表達載體。pVAX1是高拷貝質粒,在大多數哺乳動物細胞中可以高水平瞬時表達。它攜帶卡那霉素抗性基因,因此比較安全。本研究將以新型DNA疫苗載體pVAX1為骨架構建新型載體靶向融合防齲DNA質粒。
發明內容
本發明的目的是在于提供了一種靶向融合防齲DNA疫苗,用真核表達載體pVAX1替代靶向融合防齲真核表達質粒pGJA-P(專利申請號02139118.1)中的疫苗載體pCI,構建一種靶向融合防齲DNA疫苗pGJA-P/VAX。它用于人體安全性高,增強免疫效能。
本發明的另一個目的是在于提供一種制備靶向融合防齲DNA疫苗的方法,生產成本低廉,方法簡單,純化簡單且產物純度高。
本發明所提供的靶向融合防齲DNA疫苗為大腸桿菌Escherichia coliJM109/pGJA-P/VAX,保藏單位中國典型培養物保藏中心,地址中國.武漢.武漢大學,保藏日期2004年3月23日,保藏編號.CCTCCNOM204028。
其步驟如下A.用限制性酶NheI和NotI酶切處理靶向融合防齲真核表達質粒pGJA-P切下細胞毒性T淋巴細胞抗原4信號肽、胞外區的序列和Igγ1鉸鏈區、恒定區融合基因(CTLA-4-Ig目的基因),變形鏈球菌葡糖基轉移酶的GLU區序列(GLU片段)和變形鏈球菌表面蛋白抗原PAc的A-P片段(A-P片段),用相同限制性酶處理pVAX1載體;B.電泳膠回收純化CTLA-4-Ig目的基因、GLU片段、A-P片段和NheI和NotI酶切處理的pVAX1載體片段;C.將上述兩種純化的目的片段在T4DNA連接酶作用下連接,轉化感受態細胞,接種在卡那霉素陽性LB平板上;D.篩選重組陽性克隆,接種在卡那霉素陽性的LB培養基中,搖菌,提取質粒,酶切證實構建的正確性,并命名為pGJA-P/VAX。
pGJA-P/VAX靶向融合防齲DNA疫苗的基因序列為SEQUENCE LISTING。
與其它DNA疫苗相比,pGJA-P/VAX的載體骨架具有巨細胞病毒CMV的早期啟動子/增強子(CMV immediate-early enhancer/promoter),該啟動子增強表達的能力顯著高于其它如勞斯肉瘤病毒啟動子LTR、猴病毒40(SV40)等啟動子,使重組蛋白能夠高效高水平表達;pGJA-P/VAX具有牛生長激素(BGH)多聚腺苷酰化信號,允許高效轉錄終止以及mRNA的多聚腺苷酰化作用;pGJA-P/VAX具有卡那霉素抗性基因,用于人可以避免不必要的過敏反應;pGJA-P/VAX攜帶人CTLA4信號肽、胞外區的序列和Igγ1鉸鏈區、恒定區融合基因,因此可以利用CTLA4與其配體牢固結合的特性將宿主表達出的抗原蛋白引導至APC表面,大幅度增強DNA疫苗的免疫效能,同時由于Igγ1部分功能區的存在使使重組蛋白在體內更加穩定,半衰期延長,利于體內應用;pGJA-P/VAX能夠表達變形鏈球菌的兩種重要毒力因子,因此其防齲效果比僅攜帶A-P片段的DNA疫苗為佳。
與多肽防齲疫苗相比,pGJA-P/VAX DNA防齲疫苗具有以下優點①pGJA-P/VAX質粒物理化學性質穩定,20-25℃下即可保存,便于運輸使用,而多肽疫苗一般需要冷藏保存等特殊條件;②pGJA-P/VAX簡化了疫苗的生產步驟,僅需完成基因工程的上游部分,省卻了下游重組多肽的表達和純化過程,短時間內可以得到大量的質粒,而且pGJA-P/VAX質粒的純化方法較為簡單且產物純度很高,而多肽疫苗制備純化相對困難復雜,一般需耗時數周;③多肽防齲疫苗激發機體產生免疫反應的能力較差,需要添加各種免疫佐劑,但這些佐劑經常引起嚴重的炎癥反應,大大限制了多肽疫苗的應用,pGJA-P/VAX同時攜帶人CTLA4信號肽、胞外區的序列和Igγ1鉸鏈區、恒定區融合基因,因此可以利用CTLA4與其配體牢固結合的特性將宿主表達出的抗原蛋白引導至APC表面,大幅度增強DNA疫苗的免疫效能,避免使用各種對人體有害的佐劑;④多肽疫苗在體內很不穩定易被蛋白酶降解,因而要接種較大量才能引起明顯的免疫反應,且要多次接種以維持效果。而pGJA-P/VAX如同其它DNA疫苗一樣,少量接種即可以誘導機體的免疫應答。另外,pGJA-P/VAX能夠表達變形鏈球菌的兩種重要毒力因子,其防齲效果比僅攜帶A-P片段的DNA疫苗為佳,同時也應比不含CTLA4信號肽、胞外區的序列和Igγ1鉸鏈區、恒定區融合基因的其他防齲DNA疫苗效果要佳。

具體實施例方式
下面根據附圖對本發明作進一步詳細描述根據圖1、圖2可知,運用分子生物學專業軟件DNASIS綜合DNA序列分析軟件(日本日立公司)、Gene Construction kit 2.0基因模擬克隆軟件(美國Textco公司)分析和設計具有新型載體靶向融合防齲DNA疫苗并模擬克隆全過程。pGJA-P/VAXA新型載體靶向融合防齲DNA疫苗的構建全過程用限制性酶NheI和NotI酶切處理靶向融合防齲真核表達質粒pGJA-P以及pVAX1載體;電泳酶切產物,切下靶向融合基因(包括CTLA-4-Ig目的基因、GLU、A-P片段)和NheI和NotI酶切處理的pVAX1載體片段,膠回收純化目的片段;將上述兩種純化的目的片段在T4DNA連接酶作用下20-25℃連接過夜,次日轉化感受態細胞,接種在卡那霉素陽性LB平板上;篩選重組陽性克隆,接種在卡那霉素陽性的LB培養基中,搖菌,提取質粒,酶切證實構建的正確性,并命名為pGJA-P/VAX。pVAX1經KpnI單酶切得到了3.0kb片段,pGJA-P/VAX經KpnI單酶切得到了7.2kb片段,經NheI和NotI雙酶切,得到2.9kb、2.2kb、2.1kb片段,電泳結果表明pGJA-P/VAX的插入片段大小與預期結果一致(圖2)。
根據圖3、圖4、圖5、圖6、圖7可知,CHO細胞系用細胞培養液D/F(Gibco)37℃、5%CO2培養。培養瓶中預先加入蓋玻片,使用轉染劑梭華-SofastTM基因轉染試劑(廈門太陽馬生物工程有限公司)進行轉染。過程首先制備梭華-SofastTM/DNA復合物的制備,將1-2μg的DNA質粒和3-5μl梭華-SofastTm分別稀釋于100μl的不含血清和抗菌素的D/F中,輕輕混勻。將梭華-SofastTM稀釋液滴加到DNA稀釋液中,一邊滴加一邊混勻。20-25℃孵育15-20分鐘。將梭華-SofastTM/DNA復合物加到培養瓶中并輕輕搖動使均勻混合。設置空載體對照以及pGJA-P陽性對照。放置37℃ CO2孵育箱孵育24-48小時后,取出蓋玻片,將轉染實驗后培養板中的蓋玻片取出,PBS液漂洗3×2分鐘。中性福爾馬林(10%甲醛,以0.01M PBS稀釋)固定10分鐘。0.01M PBS洗滌3×5分鐘。加入山羊血清在20-25℃下封閉30分鐘。甩去多余液體,加1∶50兔抗PAc抗體或1∶50兔抗GTF抗體4℃過夜,次日PBS洗滌3×5分鐘。加入生物素化羊抗兔IgG,37℃溫育30分鐘,PBS洗滌3×5分鐘,加入Cy3熒光素標記的SABC后置37℃溫育30分鐘,PBS洗滌3×5分鐘。熒光顯微鏡觀察記錄。陽性對照和pGJA-P/VAX轉染細胞鏡下呈現強紅色熒光(圖3-6),空載體轉染細胞鏡下無熒光(圖7-8)。證實了重組融合蛋白可以在真核細胞中正確表達。
DNA疫苗最終要應用在人體,而猴與人的生理狀況十分相近,遺傳背景也很相近,因此猴是驗證DNA疫苗能否在人體中起作用的理想模型。采用了將pGJA-P/VAX經三角肌肌注免疫和將pGJA-P/VAX與局部麻醉藥Bupivacaine形成的復合物經鼻粘膜滴注免疫的方法免疫獼猴,用ELISA法檢測血清與唾液中的特異性抗體,評價DNA疫苗的效能。實驗分組見附表1。

全文摘要
本發明公開了一種靶向融合防齲DNA疫苗及制備方法,大腸桿菌Escherichia coli JM109/pGJA-P/VAX,CCTCC NoM204028。用限制性酶NheI和NotI酶切處理靶向融合防齲真核表達質粒pGJA-P切下靶向融合基因(包括CTLA-4-Ig目的基因、GLU、A-P片段),將靶向融合基因克隆到pVAX1載體中,酶切證實構建的正確性,并命名為pGJA-P/VAX,轉染真核細胞CHO細胞系,證實可以在真核細胞正確表達重組蛋白。本發明方法簡單,安全性高,避免產生對氨卞青霉素的過敏反應,生產成本低廉,可大幅度提高其免疫效能。
