Nature子刊:突破性方法——高效表达生物活性蛋白,快速生产大量药物!

2022-08-20 转化医学网 转化医学网

螺旋藻是一种光合蓝藻,是一种营养丰富的食品,也是全球唯一作为食品商业化养殖的微生物。

导读:近期研究报告了螺旋藻中生物活性蛋白稳定、高水平表达的基因工程方法,螺旋藻通过将基于食物的生产宿主的安全性与可获得的遗传操作和微生物平台的高生产率相结合,为制造口服递送的治疗性蛋白质提供了一个有利的系统。

一种常见的食物来源已经转化为一个生物制造平台,为目前缺乏有效治疗方法的常见疾病快速生产大量的生物药物提供了一种方法。Lumen Bioscience的研究人员报告了他们突破性的基因工程方法,利用适合生物制药制造的大规模培养和加工方法,在螺旋藻中高效表达生物活性蛋白。

该论文还详细介绍了这些生产的、口服给药的抗弯曲杆菌中和抗体的有利临床前和早期临床试验,弯曲杆菌是发展中国家婴儿死亡的主要原因,也是日益增长的抗生素耐药威胁。产品LMN-101现在正在进行2期临床试验,BARDA的CARB-X项目正在资助开发该产品的第二代版本。

研究发表在《Nature Biotechnology》上,题为“Development of spirulina for the manufacture and oral delivery of protein therapeutics”。

“在过去的50年里,基因工程已经改变了生物产品的制造,然而基于植物的生物制药生产仍然是一个难以捉摸的挑战,”Lumen Bioscience的主要作者和联合创始人兼首席科学官Jim Roberts博士说。“基于螺旋藻的生物制造将基于食物的生物技术的安全性与基因工程方法相结合,生产出可能解决当前药物开发工具未能解决的医疗需求的生物制药。”

螺旋藻是一种光合蓝藻,是一种营养丰富的食品,也是全球唯一作为食品商业化养殖的微生物。之前试图将这种安全的、可扩展的食物来源转化为生物制造平台已被证明是徒劳的。在新论文中,Lumen研究人员详细描述了螺旋藻中蛋白质治疗药物组成性和稳定表达的方法,其生产率和效力比其他基于食物的平台中可实现的要高几十到数百倍。这些可扩展性和效力的进步使得口服给药的生物制剂首次在商业上可行。

“将治疗用的蛋白质生物制剂递送到肠道是一个巨大的挑战,为此长期以来人们一直认为胃肠道的靶点几乎是不可用药物治疗的,”Roberts说。“螺旋藻平台巧妙地应对了这一挑战。它可用于生产和递送预防和治疗胃肠道疾病所需的大量可摄入生物治疗药物。预防和治疗腹泻病,即论文中报告的例子,提供了一个极好的案例研究:这些高发疾病对发展中国家具有毁灭性的影响,但传统的制药工具尽管经过几十年的大量投资,却未能产生解决方案。本研究中描述的方法为暴露于这些疾病的个体提供了新的希望。”
