Description

赤红球菌产品在治疗白色念珠菌感染引起的疾病中的用途
本公开要求2019年01月15日提交的中国专利申请《赤红球菌细胞壁骨架及其用途》(申请号201910036001.4)以及2019年10月25日提交的中国专利申请《一种分离的赤红球菌》(申请号201911022193.X)的优先权,它们的全部内容通过引用并入此处。
技术领域
本公开涉及医学领域、微生物领域、生物制药领域。具体而言,涉及赤红球菌及其细胞壁成分、制剂、药物组合物、制备方法、以及赤红球菌的细胞壁成分在制备药物/医疗装置中的用途。
背景技术
赤红球菌(Rhodococcus ruber)(也称为红色红球菌),革兰氏阳性菌。通常而言,菌落呈桔黄色或呈桔红色,圆形;菌落大小约1mm至2mm;细胞形态为球状或短杆状;可形成初级分枝菌丝体;无鞭毛。赤红球菌好氧,化能异养。
目前,已有研究人员对赤红球菌进行了全基因测序。例如,樊欣等人对赤红球菌SD3株的全基因组进行测序,并进行生物信息学分析。SD3株的全基因组长度大约为5.37Mb,GC含量约为70.63%,GenBank登录号为CP029146(樊欣,赤红球菌SD3全基因组测序及其热休克蛋白DnaK的表达分析,基因组学与应用生物学,2019年1月)。
红球菌属Rhodococcus,因其自身具有非常强的有机物耐受性,以及较宽的降解谱,能够适应多种生存环境。因此,红球菌属被广泛应用于污染修复、有机化合物降解、污水处理等领域。目前,赤红球菌的主要应用领域在于环境治理,参见CN108862590A、CN107151635A、CN102250796A、CN1519312A、CN103627653A、CN101033454A、CN108130288A、CN104830738A、CN101619299A、CN103509833A、CN106434466A、CN101580808A、CN102604875A、CN103160491A、CN106591168A、CN106591172A、CN105820982A。
CN109576180A中公开了一种从广州市番禺区附近郊野红土中筛 选到的菌RDC-01,经16S rRNA基因序列分析和培养特性鉴定,该菌株鉴定为赤红球菌。将该菌灭活后,作为免疫佐剂添加入动物用的灭活疫苗中,发现可以促进动物生产抗体。
然而,赤红球菌在人类医学领域中的应用,尚未有报道。
白色念珠菌(又称假丝酵母菌)是一种广泛存在于自然界的腐生菌,属于人体的正常寄生菌群。它是一种条件致病菌,在人体免疫功能下降或受某些因素的影响下,寄生的白色念珠菌可产生致病性而引起疾病。
白色念珠菌是一种双相真菌,有酵母相和菌丝相。在寄生时为酵母相,一般无致病性;但在一定条件时可转变为有致病性的菌丝相。白色念珠菌可以感染机体任何组织和器官而引起,例如:口腔感染引起的疾病(如鹅口疮、舌炎、唇炎等);感染生殖器引起的疾病(例如念珠菌性外阴阴道炎、念珠菌性包皮龟头炎等);感染皮肤引起的疾病(例如念珠菌性间擦疹、念珠菌性肉芽肿、慢性皮肤黏膜念珠菌病);感染支气管、肺部引起的疾病(支气管炎、肺炎、胸膜炎等);感染消化道引起各种的疾病(消化道念珠菌病)。
由于白色念珠菌患者大量服用各种抗生素引起免疫能力低下和菌药物耐受,使念珠菌感染引起的疾病反复发作,目前临床上缺少有效理想的药物和治疗方法。

具体实施方式
“分离”是指本公开的赤红球菌脱离其原始生长环境。
技术人员知晓,革兰氏阳性菌和革兰氏阴性菌的细胞壁结构不同。具体而言,革兰氏阳性菌的细胞壁较厚(通常20nm至80nm),含有约90%的肽聚糖和约10%的磷壁酸(一种由醇和磷酸分子形成的聚合物,通常以糖酯或氨基酸酯的形式存在)。肽聚糖层致密,甚至多达20层。然而,革兰氏阴性菌的细胞壁比革兰氏阳性菌的细胞壁要薄很多,结构较复杂,分为外膜(outer membrane)和肽聚糖层(通常2nm至3nm)。
肽聚糖层是细菌细胞壁中特有成分,是一种杂多糖的衍生物。每一个肽聚糖的单体包括3部分:糖单元(例如,至少两种糖分子通过糖苷键连接起来,构成肽聚糖的框架性结构)、肽尾(由若干氨基酸连接成的短肽链,其连接在N-乙酰胞壁酸分子上)、和肽桥(将相邻“肽尾”交联形成高强度的网状结构)。不同细菌的肽桥、肽尾、交联方式是不同的。
分离的赤红球菌细胞壁
在本公开中,“分离的赤红球菌细胞壁”既可以理解为完整的细胞壁,也可以理解为不完整的细胞壁(例如,破碎的、或部分降解的)。在本公开的教导下,技术人员将理解,显示出所需活性的成分来自赤红球菌的细胞壁(例如,是细胞壁本身或其组成)。因此,在临床应用中允许采用完整的细胞壁、经破碎的细胞壁、细胞壁的不完全降解产物、细胞壁的组成成分、细胞壁的提取物等各种形式,这些都包含在本公开范畴之内。
细胞壁骨架
构成细胞壁主体结构的组成成分;但不能理解为仅仅表示细胞壁当中的交联网状实体,技术人员理解不排除交联网状实体上所吸附、结合、携带的其他细胞壁成分。
赤红球菌
本公开实施方案中所用的赤红球菌是指红球菌属(Rhodococcus)的赤红球菌种(Rhodococcus ruber),不限于特定的细胞株。
非限制性示例包括TOY7株(南京农业大学农业环境微生物菌种保藏中心)、CGMCCNo.4795、DSM43338、CCTCC No.2012035、CGMCC No.16640、CGMCC No.17431。
赤红球菌的鉴定
根据已知的或未来的微生物鉴定技术,技术人员可以对一株细菌进行分类学鉴定,例如可用的鉴定技术包括形态学、生理生化特征、16S rRNA等。技术人员理解,随着科技的发展,鉴定技术涉及不同的手段,在较早的时期主要采用形态学和生化鉴定方式,但是这种方法的可靠程度不高。测序技术出现后,技术人员可以利用更为可信的方式鉴定菌株。例如,当16S rRNA的DNA序列被鉴定为具有97%(含)以上相似性时,判定两个菌属于相同的种(华苟根等人,红球菌属的分类及应用研究进展,微生物学通报,2003:30(4))。就赤红球菌而言,将保藏在国际(或国家级)菌种保藏单位中的已知菌株作为模式菌株,并与其进行比对。
剂型
本公开的药物或药物组合物或活性成分或产品,可以体现为但不限于以下形式:软膏剂、乳膏剂、硬膏剂、凝胶剂、片剂、洗剂、酊剂、搽剂、油剂、糊剂、散剂、粉剂、喷雾剂、气雾剂、栓剂、贴片、悬液、漱口液、口含片、护肤品(洁面乳、化妆水、精华、乳液、面霜、面膜)、敷料、贴片、绷带、贴膜、纱布。
制剂单元
本公开的药物或药物组合物或活性成分或产品,可以制备成单位制剂(单元制剂)的形式。
在一些实施方案中,所述药物(或制剂、或治疗剂、或医疗装置)中的单位剂量含有:
-1μg至1000μg所述的赤红球菌产品;或
-1μg至1000μg所述的赤红球菌细胞壁;或
-1μg至1000μg所述的赤红球菌细胞壁骨架。
单位剂量的具体示例是1、2、5、10、15、20、25、30、40、50、55、56、57、58、59、60、61、62、63、65、66、67、68、69、70、80、90、100、150、200、250、300、350、400、450、500μg±10%、以及上述任意两个数值之间的范围。
“施用”、“给予”、“提供给”、“处理”当应用于动物、人、细胞、组织、器官或生物样品时,是指药物或医疗装置与动物、人、细胞、组织、器官或生物样品接触。
“治疗”意指给予受试者内用或外用药物(治疗剂、活性成分或组合物)(如,根据本公开的赤红球菌细胞壁或其药物组合物)或医疗装置,在被治疗的受试者(或群体)中缓解(减轻、延迟、改善、治愈)一种或多种疾病症状,以至于达到临床可测量的程度,其中所述的受试者已经患有、疑似患有或易感于一种或多种疾病或其症状。
有效缓解任何疾病症状的药物(治疗剂、活性成分或组合物)的量称为治疗有效量。可根据多种因素变化,例如受试者的疾病状态、年龄和体重。应当理解,在缓解单个受试者的目标疾病或其症状时,药物(治疗剂、活性成分或组合物)可能无效,但是根据本领域已知的任何统计学检验方法(如Student T检验、卡方检验、依据Mann和Whitney的U检验)确定,药物(治疗剂、活性成分或组合物)在统计学意义上对目标疾病或其症状是有效的。
“任选”意味着其随后所描述的事项可以发生,但不必须发生;需要视情况而定。例如,“任选地,进行分装”意味着允许对产品进行分装,但是不是必须进行分装;分装与否不影响技术效果的实现。
“一个”、“一”、“单个”、“该”,如果没有明确说明,也包括复数形式。
以下结合实施例、制备例和测试例,进一步描述本公开。但这些实施例、制备例和测试例并非限制着本公开的范围。当未注明具体条件时,按照常规条件、按照原料供应商所建议的条件操作。未注明具体来源的试剂,为市场购买的常规试剂。
技术人员尤其理解,虽然以下具体示例采用了特定的细胞株,但是技术效果的实现不限于该特定的细胞株,任何属于红球菌属赤红球菌种的(Rhodococcus ruber)物种均适用。
