Description
技术领域
本发明涉及一株可改善血脂紊乱的普拉梭菌及其应用,属于微生物技术领域以及医药技术领域。
背景技术
血脂紊乱(Dyslipidemia)是指涉及血液任何或所有脂类以及脂蛋白异常升高水平的情况。脂质(脂溶性分子)由载脂蛋白运送,而载脂蛋白密度及结构类型决定该载脂蛋白如何对代谢产生影响。血中脂质(Lipid)主要的成分有胆固醇(cholesterol;CE)、三酸甘油酯(triglyceride;TG)与含磷脂类(phospholipid),因不溶于水,必须先与载脂蛋白AI、载脂蛋白B100结合成可溶性的脂蛋白(Lipoprotein)才可运行于血液中,输送到全身各部位。高密度脂蛋白(HDL-C)可以移除血液中多的胆固醇,而低密度脂蛋白(LDL-C)则含有大量胆固醇。。研究表明,血脂紊乱会导致动脉粥样硬化、脂肪肝、冠心病等一系列代谢性疾病。此外,模型形式的血脂紊乱还可诱发急性胰腺炎。
人类肠道微生物群的基础知识和应用知识的最新进展已经改变了当前对血脂紊乱的看法和有希望的治疗方式。人类肠道微生物群已被确定为一个复杂的生态系统,包括多种细菌物种,其数量超过1000万亿(1014数量级),为人体细胞总数的10倍以上。在漫长的进化过程中,肠道微生与人类达成了良好的互利关系,对人体的营养、代谢和免疫都扮演着重要的角色。研究表明,较之健康人群肠道菌群,血脂紊乱患者的肠道中有益菌减少而有害菌增多,且肠道中代谢物也发生了改变如短链脂肪酸的减少。
目前,治疗血脂紊乱策略主要有:调节饮食、体育锻炼、以及药物治疗。饮食锻炼一般疗法,即吃低热量、低脂食物,再结合有氧锻炼,但该种方法一般认为对普通大众并不成功,需要长期经常性地坚持;药物治疗通常是他汀类药物(Statins)、罗氏鲜(orlistat)和立控醇(Repatha),其机制主要包括抑制HDG-CoA还原酶活性,阻挡NPC1L1运送蛋白的作用,抑制PCSK9酶的活性等。但药物治疗通常会带来一定的副作用(例如腹泻和肝损伤等),且一旦停止服用容易反弹。
针对上述药物的缺点,研究人员开始尝试使用益生菌制剂治疗血脂紊乱。益生菌制剂对人体安全健康,且给药方式简便。因此,通过服用益生菌来调节肠道从而预防和治疗血脂紊乱成为一种可能的方案。

实施例1:普拉梭菌的筛选及菌种鉴定
(1)筛选
以来源于江苏无锡地区的健康人体粪便为样本,在样品采集后的一小时内立即将其转移至厌氧工作站内进行处理。取一勺粪便样品,加入到5mL PBS(加入0.05%半胱氨酸)中,混匀进行梯度稀释,选择10-5~10-7的梯度稀释液涂布在上述M2GSC固体培养基上,于37℃培养48h,挑取典型菌落至两份M2GSC固体培养基中,一份置于厌氧工作站培养(命名为A板),另一份置于厌氧工作站外暴露30min再拿回至厌氧工作站培养(命名为B板),于培养温度均为37℃,培养48h后挑取B板中不长的菌落至M2GSC固体培养基上划线纯化,同时进行特异性引物检测。纯化完成后,挑取单菌落转接至M2GSC液体培养基中于37℃培养,于厌氧工作站内抽滤收集菌泥,30%甘油保藏,得到菌株菌株CCFM1205。
(2)鉴定
挑取CCFM1205单菌落进行菌落PCR,以对其16s rDNA进行扩增和测序(由金唯智公司进行)。CCFM1205的16s rDNA的序列为SEQ ID NO.1,将该序列在NCBI中进行核酸序列比对,结果显示菌株均为普拉梭菌,命名为普拉梭菌(Faecalibacterium prausnitzii)CCFM1205。
实施例2:普拉梭菌的培养
将普拉梭菌(Faecalibacterium prausnitzii)CCFM1205接入M2GSC固体培养基中于37℃培养48h后,观察其菌落,发现其菌落凸面,半透明,边缘完整,湿润。
将普拉梭菌(Faecalibacterium prausnitzii)CCFM1205按2%接种量接入M2GSC液体培养基中,并于37℃厌氧培养24h后,转入新鲜的M2GSC液体培养基中,同样条件培养24h,在厌氧工作站内抽滤获得菌泥,继而用0.1M PBS(pH 7.2,含0.05%半胱氨酸)洗涤重悬后得到菌浓为1×109CFU/mL悬液,使用密封性良好的冻干瓶加塞保存菌悬液,当天使用。
实施例3:普拉梭菌对血脂紊乱小鼠血清HDL-C的影响
将32只SPF级雄性C57BL/6J小鼠(8周龄,18-22g)随机分为4组,每组8只,分别为空白组、模型组、A2-165组和CCFM1205组。小鼠饲养在江南大学实验动物中心,恒定温度21-26℃,湿度40-70%,噪声小于等于60dB,动物照度15-20LX(所有动物实验程序皆由江南大学动物福利与伦理管理委员会进行审查并批准)。
实验共13周:小鼠先适应性喂养7天,从第8天开始,开始使用高脂饲料喂养模型组小鼠和干预组小鼠,空白组仍然使用普通饲料。此外,干预组小鼠(CCFM1203组和A2-165组)从第8天开始每天分别灌胃0.2mL菌液浓度为1×109/mL的普拉梭菌CCFM1205和普拉梭菌模式菌株A2-165菌液,空白组和模型组则灌胃等量体积的PBS溶液。
实验结束后,取血并处死小鼠,血液经室温放置1h后,于4℃下3500r/min离心10min,收集血清,通过试剂盒测定血清中HDL-C含量,结果见图1。
如图1所示,相较于空白组的1.65±0.27mmol/L,模型组小鼠HDL-C含量显著下降至0.81±0.16mmol/L(P<0.05)。小鼠在喂食本发明中的菌株普拉梭菌(Faecalibacteriumprausnitzii)CCFM1205后,HDL-C含量较之模型组显著提高了64.23%(P<0.05),模式菌株A2-165的提高量为35.94%(P<0.05)。以上实验表明,普拉梭菌(Faecalibacteriumprausnitzii)CCFM1205可显著提高血脂紊乱小鼠的HDL-C含量,且效果显著优于普拉梭菌(Faecalibacterium prausnitzii)模式菌株A2-165。
实施例4:普拉梭菌对血脂紊乱小鼠血清LDL-C的影响
将32只SPF级雄性C57BL/6J小鼠(8周龄,18-22g)随机分为4组,每组8只,分别为空白组、模型组、A2-165组和CCFM1205组。小鼠饲养在江南大学实验动物中心,恒定温度21-26℃,湿度40-70%,噪声小于等于60dB,动物照度15-20LX(所有动物实验程序皆由江南大学动物福利与伦理管理委员会进行审查并批准)。
实验共13周:小鼠先适应性喂养7天,从第8天开始,开始使用高脂饲料喂养模型组小鼠和干预组小鼠,空白组仍然使用普通饲料。此外,干预组小鼠(CCFM1203组和A2-165组)从第8天开始每天分别灌胃0.2mL普拉梭菌CCFM1205和普拉梭菌模式菌株A2-165菌液(1×109/mL),空白组和模型组则灌胃等量体积的PBS溶液。
实验结束后,取血并处死小鼠,血液经室温放置1h后,于4℃下3500r/min离心10min,收集血清,通过试剂盒测定血清中LDL-C含量,结果见图2。
如图2所示,相较于空白组的0.28±0.04mmol/L,模型组小鼠LDL-C含量显著上升至0.88±0.17mmol/L(P<0.05)。小鼠在喂食本发明中的菌株普拉梭菌(Faecalibacteriumprausnitzii)CCFM1205后,LDL-C含量较之模型组显著降低了41.94%(P<0.05),模式菌株A2-165组降低了24.24%(P<0.05)。以上实验表明,普拉梭菌(Faecalibacteriumprausnitzii)CCFM1205可显著降低血脂紊乱小鼠的LDL-C含量,且效果显著优于普拉梭菌(Faecalibacterium prausnitzii)模式菌株A2-165。
实施例5:普拉梭菌对血脂紊乱小鼠血清TC的影响
将32只SPF级雄性C57BL/6J小鼠(8周龄,18-22g)随机分为4组,每组8只,分别为空白组、模型组、A2-165组和CCFM1205组。小鼠饲养在江南大学实验动物中心,恒定温度21-26℃,湿度40-70%,噪声小于等于60dB,动物照度15-20LX(所有动物实验程序皆由江南大学动物福利与伦理管理委员会进行审查并批准)。
实验共13周:小鼠先适应性喂养7天,从第8天开始,开始使用高脂饲料喂养模型组小鼠和干预组小鼠,空白组仍然使用普通饲料。此外,干预组小鼠(CCFM1203组和A2-165组)从第8天开始每天分别灌胃0.2mL普拉梭菌CCFM1205和普拉梭菌模式菌株A2-165菌液(1×109/mL),空白组和模型组则灌胃等量体积的PBS溶液。
实验结束后,取血并处死小鼠,血液经室温放置1h后,于4℃下3500r/min离心10min,收集血清,通过试剂盒测定血清中TC含量,结果见图3。
如图3所示,相较于空白组的1.97±0.40mmol/L,模型组小鼠TC含量显著上升至5.38±0.56mmol/L(P<0.05)。小鼠在喂食本发明中的菌株普拉梭菌(Faecalibacteriumprausnitzii)CCFM1205后,TC含量较之模型组显著下降了34.73%(P<0.05),A2-165组降低了21.93%;以上实验表明,普拉梭菌(Faecalibacterium prausnitzii)CCFM1205可显著降低血脂紊乱小鼠的TC含量,且效果显著优于普拉梭菌模式菌株A2-165。
实施例6:普拉梭菌对血脂紊乱小鼠血清TG的影响
具体步骤如下:
将32只SPF级雄性C57BL/6J小鼠(8周龄,18-22g)随机分为4组,每组8只,分别为空白组、模型组、A2-165组和CCFM1205组。小鼠饲养在江南大学实验动物中心,恒定温度21-26℃,湿度40-70%,噪声小于等于60dB,动物照度15-20LX(所有动物实验程序皆由江南大学动物福利与伦理管理委员会进行审查并批准)。
实验共13周:小鼠先适应性喂养7天,从第8天开始,开始使用高脂饲料喂养模型组小鼠和干预组小鼠,空白组仍然使用普通饲料。此外,干预组小鼠(CCFM1203组和A2-165组)从第8天开始每天分别灌胃0.2mL普拉梭菌CCFM1205和普拉梭菌模式菌株A2-165菌液(1×109/mL),空白组和模型组则灌胃等量体积的PBS溶液。
实验结束后,取血并处死小鼠,血液经室温放置1h后,于4℃下3500r/min离心10min,收集血清,通过试剂盒测定血清中TG含量,结果见图4。
如图4所示,相较于空白组的0.84±0.13mmol/L,模型组小鼠TG含量显著上升至1.85±0.28mmol/L(P<0.01)。小鼠在喂食本发明中的菌株普拉梭菌(Faecalibacteriumprausnitzii)CCFM1205后,TG含量较之模型组显著下降了44.87%,接近正常组小鼠TG水平,而A2-165组相对于模型组仅降低了27.90%。以上实验表明,普拉梭菌(Faecalibacterium prausnitzii)CCFM1205可显著降低血脂紊乱小鼠的TG含量,且效果显著优于普拉梭菌(Faecalibacterium prausnitzii)模式菌株A2-165。
实施例7:普拉梭菌对血脂紊乱小鼠血清FFA的影响
将32只SPF级雄性C57BL/6J小鼠(8周龄,18-22g)随机分为4组,每组8只,分别为空白组、模型组、A2-165组和CCFM1205组。小鼠饲养在江南大学实验动物中心,恒定温度21-26℃,湿度40-70%,噪声小于等于60dB,动物照度15-20LX(所有动物实验程序皆由江南大学动物福利与伦理管理委员会进行审查并批准)。
实验共13周:小鼠先适应性喂养7天,从第8天开始,开始使用高脂饲料喂养模型组小鼠和干预组小鼠,空白组仍然使用普通饲料。此外,干预组小鼠(CCFM1203组和A2-165组)从第8天开始每天分别灌胃0.2mL普拉梭菌CCFM1205和普拉梭菌模式菌株A2-165菌液(1×109/mL),空白组和模型组则灌胃等量体积的PBS溶液。
实验结束后,取血并处死小鼠,血液经室温放置1h后,于4℃下3500r/min离心10min,收集血清,通过试剂盒测定血清中FFA含量,结果见图5。
如图5所示,相较于空白组的0.97±0.20mmol/L,模型组小鼠FFA含量显著上升至2.02±0.22mmol/L(P<0.05)。小鼠在喂食本发明中的菌株普拉梭菌(Faecalibacteriumprausnitzii)CCFM1205后,FFA含量较之模型组显著下降了45.94%(P<0.05),较之正常组无显著差异,而A2-165组仅降低了28.93%。以上实验表明,普拉梭菌(Faecalibacteriumprausnitzii)CCFM1205可显著降低血脂紊乱小鼠的FFA含量,且效果显著优于普拉梭菌(Faecalibacterium prausnitzii)模式菌株A2-165。
实施例8:含有普拉梭菌CCFM1205的固体饮料的制备
将普拉梭菌CCFM1205按照占培养基总质量3%的接种量接种到培养基中,于37℃下培养18h,得到培养液;将培养液离心,得到菌体;将菌体用pH为7.2的磷酸盐缓冲液清洗3次后用海藻糖浓度为100g/L的海藻糖冻干保护剂重悬(冻干保护剂和菌体的质量比为2:1),得到菌浓为5×108CFU/mL的重悬液;将重悬液采用真空冷冻法进行冻干,得到普拉梭菌CCFM1205菌粉。
