Description
发明名称:一种脂多糖结合蛋白多肽及其制药用途 技术领域
[0001] 本发明属于生物医药技术领域, 具体涉及一种包含 15个氨基酸的脂多糖结合蛋 白多肽及其在制备用于预防和 /或治疗由革兰氏阴性细菌引起的败血症的药物中 的用途。
背景技术
[0002] 败血症是致病菌或条件致病菌侵入血液循环中生长繁殖, 产生毒素和其他代谢 产物所引起的急性全身性感染, 临床上以寒战、 高热、 皮疹、 关节痛及肝脾肿 大为特征, 部分可有感染性休克和迁徙性病灶。 引起败血症的原因有二: 一、 人体因素: 当皮肤粘膜有破损或发生化脓性炎症吋, 细菌则容易侵入体内; 人 体的免疫反应可分为非特异性免疫反应及特异性免疫反应两种, 后者又可分为 细胞免疫与体液免疫两方面, 当机体免疫功能下降吋, 不能充分发挥其吞噬杀 灭细菌的作用, 就会引起败血症; 条件致病菌所引起的医源性感染也逐渐增多 。 二、 细菌因素: 主要与病原菌的毒力和数量有关。 毒力强或数量多的致病菌 进入机体, 引起败血症的可能性较大。
[0003] 革兰氏阴性细菌感染是导致败血症的重要原因, 其胞壁成分脂多糖 (LPS) 诱 导产生的系统性炎症和微循环障碍对败血症发生的多器官功能障碍和败血性休 克起关键作用。 脂多糖 (LPS) 是革兰氏阴性杆菌细胞壁的组成成分之一, 一般 位于细胞壁的最外层, 厚度约为 8~10nm, 具有很强的致炎作用。
[0004] 尽管目前败血症的治疗已采取抗感染、 免疫调控和支持治疗等综合措施, 但是 败血症的发病率和死亡率仍然居高不下。 究其原因, 主要是对败血症发病机理 的认识远远不足。 血液中 LPS不存在游离形式。 已知生物体具有 LPS清除机制, 包括 LBP、 sCD14、 CTBP及其它脂蛋白, 它们与 LPS的结合将其递呈给肝脏的三 种细胞 (包括枯否细胞、 肝细胞及星状细胞) , 通过细胞内的降解排入胆汁, 而被解毒。 然而, 在发生败血症吋, 血液中的 LPS浓度居高不下, 说明 LPS借助 于与宿主蛋白的结合而逃逸了清除机制, 但迄今为止, 仍不清楚 LPS到底劫持了
哪些宿主蛋白。

本发明的实施方式
[0022] 下面结合附图和具体实施例对本发明做出进一步的描述。 需要说明的是, 下列 实施例仅用于解释本发明的技术方案, 而并不旨在限制其保护范围。 另外, 除 非特殊说明, 下列实施例中使用各种试剂、 药品和仪器均可通过商业手段获得
[0023] 实施例一: 从血浆 HK蛋白中筛选功能性多肽 DHG15并检测其结合性能。
[0024] 血浆中的 HK蛋白共有 6个结构域, 其中第一至第三结构域 (D1~D3) 组成 HK 的重链 (Heavy
chain, HC) , 第四至第六结构域 (D4~D6) 组成 HK的轻链 (Light chain, LC) 。 运用 Bac-to-Bac昆虫细胞表达系统制备了 HK的重链与轻链蛋白, 并使用 Wester n blotting鉴定所纯化的 HC (55KD) 与 LC (35KD) 蛋白, 其结果如图 1所示。
[0025] 为了研究 HK蛋白与 LPS的结合位点, 分别将 200 ng
HK:、 HC、 LC蛋白与 LPS或 PBS孵育 (4°C, 30 min) 。 吸取 30
μΐ混匀的 Polymyxin-B (Sigma) 至 1.5 ml离心管中, 离心去上清, 1 ml PBS洗两 次 (7000 rpm, 2 min) 。 将各种蛋白样品与处理后的 Polymyxin-B孵育 (4°C, 5 min) , 离心去上清, PBS洗两遍。 采用 60 μΐ蛋白上样缓冲液重悬 Polymyxin-B沉 淀, 100°C煮 10 min, 吸取 10 μΐ进行 Western blotting鉴定, 并孵育 HK抗体 (百奇 生物) 。
[0026] 如图 2所示, HK和 LC能够与 LPS结合, 从而被 polymyxin-B微珠共沉淀, 提示 H K可能通过 LC与 LPS结合。
[0027] 为了进一步验证上述结论, 使用 Biacore分析方法, 分别检测 HK和 LC与 LPS结 合的亲和力。 采用 pH=7.4的 Running buffer稀释 HK样品, 稀释一系列浓度至 0 nM 、 6.4 nM、 19.3 nM、 57.7 nM、 173 nM、 520 nM。 按照 Biacore XI 00 control soft 的 protocol, 将 HK蛋白偶联到 HPA芯片上, 偶联水平为 3000 RU。 设置进样吋间 为 180 s, 解离吋间为 500 s, 再生液为 0.1M HC1, 再生吋间为 120 s。 按照 Biacore X100 control soft的 protocol, 进行上机测试。
[0028] 如图 3所示, HK、 LC与 LPS均有物理性的直接结合, Kd值分别为 1.713*10 -7M 和 1.524*10 -9 M。 上述结果说明, 与 HK相比, LC与 LPS的结合力更强, 进一步提 示 LC含有 HK与 LPS直接结合的位点。
[0029] 为了进一步研究究竟是 LC中的哪一个结构域与 LPS发生了结合, 使用 Bac-to-Ba c昆虫细胞表达系统制备了 LC中的第四结构域 (D4) 、 第五结构域 (D5) 和第 六结构域 (D6) 蛋白, 并经过 Western blotting鉴定。 使用 polymyxin-B微珠与 D4 、 D5或 D6蛋白孵育后, 检测其与 LPS的结合情况, 只有 D5可以被 polymyxin-B共
沉淀下来, 提示 D5是 HK与 LPS的结合位点, 其结果如图 4所示。
[0030] 随后, 合成了 D5上的 8个多肽片段 (南京金斯瑞生物科技公司) , 每个多肽片 段包含含 30个氨基酸。 将 8个多肽片段分别和 LPS共孵育后, 再和 LC相互作用, 然后使用同上的实验方法检测结合情况, 只有多肽 6和多肽 7可以抑制 LPS与 LC 的结合, 其结果如图 5所示。 比对多肽片段 6和 7的氨基酸序列可知, 其共有的序 歹 'J为 DHGHKHKHGHGHGKH (将其命名为 DHG15) 。
[0031] 据文献报道, 富含组氨酸的多肽可以中和由 LPS导致的宿主炎症反应, 而本发 明的 DHG15多肽中恰恰含有大量组氨酸, 因此推测组氨酸是 HK与 LPS结合的主 要氨基酸。 随后, 将 DHG15多肽中的组氨酸 (H) 突变为同样带正电荷的赖氨酸
(K) , 即为 DKGKKKKKGKGKGKK:。 将 DHG15多肽以及突变多肽分别与 LPS 预孵育后, 使用 polymyxin-B微珠与上述混合物孵育, 经 Western blotting检测其 与 LPS的结合情况。
[0032] 如图 6所示, DHG15多肽可以抑制 HK轻链与 LPS的结合, 而将组氨酸 (H) 突 变为赖氨酸 (K) 后, 该突变多肽不能抑制 HK轻链与 LPS的结合。 同吋, 采用 D 5中其它片段的无关多肽作为阴性对照, 提示组氨酸是 HK与 LPS结合的关键。
[0033] 实施例二: LPS通过糖链与 HK结合。
[0034] LPS主要由糖链和脂质 A两部分组成, 为了检测 LPS通过其结构上的哪一部分与 HK结合, 向 96孔板的每孔中加入 2 脂质 A、 脱脂 LPS、 LPS或 BSA (内含 0.1M Na 2C0 3, pH=9.6) , 4°C包被, 过夜。 PBS清洗孔板后, 加入 1%明胶, 37°C封 闭 l h。 PBS清洗孔板后, 各孔加入 FITC标记的 HK蛋白 (100 nM) , 37°C孵育 1 h。 吸走液体后, 采用酶标仪检测各孔中的荧光强度 (激发光: 494 nm, 发射光 : 518 nm) 。
[0035] 如图 7所示, 脱脂 LPS与 HK的结合能力最强, 相比于脂质 A与 HK的结合能力, 具有显著性差异, 提示 LPS上的糖链是 LPS与 HK结合的主要位点。
[0036] 实施例三: DHG15多肽的活性考察。
[0037] 为了研究 DHG15多肽能否改善由 LPS导致的小鼠死亡, 将小鼠随机分为两组, 通过腹腔注射方式进行给药, 一组注射与无关多肽 (200 g/只) 共孵育的 LPS ( 对照组) , 另一组注射与 DHG15多肽 (200 g/只) 共孵育的 LPS (治疗组) , 观
察两组小鼠的生存率。 结果发现, 经过 DHG15多肽处理, 可以显著改善小鼠由 L PS导致的死亡率。
[0038] 为了研究 DHG15是否会影响血浆中主要炎症因子的水平, 比较对照组小鼠和 D HG15治疗组小鼠血浆中主要炎症因子的含量。 如图 9所示, 与对照组小鼠相比, DHG15治疗组小鼠血浆中 TNF-a、 IL-lb和 IL-6的水平明显降低, 说明在由 LPS导 致的炎症反应中, DHG15可以显著抑制血浆中主要炎症因子的水平。
工业实用性
[0039] 以上结果说明, 应用 DHG15多肽可以阻断血浆 HK蛋白与 LPS的结合, 有利于 预防由革兰氏阴性杆菌引起的败血症的发病, 同吋有利于缓解发病后的症状, 起到兼顾预防和治疗的双重效果。
