背景治疗性抗体的开发是制药工业发展最快的领域之一。产生针对给定治疗靶点的高质量单克隆抗体对于药物开发的成功至关重要。然而,由于免疫耐受性,一些在小鼠和人类之间高度保守的蛋白质在小鼠中的免疫原性不是很强,使得难以使用常规方法产生抗体。方法/主要发现在本报告中,利用NZB/W小鼠的免疫耐受性受损来产生针对高度保守或自身抗原的单克隆抗体。使用两种高度保守的人抗原(MIF和HMGB 1)和一种小鼠自身抗原(TNF-α)作为例子,我们在这里证明,使用NZB/W小鼠作为免疫宿主和融合到重组抗原的T细胞特异性标签以刺激免疫系统,可以产生具有所需生物活性的高亲和力、高特异性抗体的多个克隆。结论/意义我们开发了一种有效和通用的方法,用于产生针对“困难抗原”的替代或治疗性抗体,以促进治疗性抗体的开发。
Background Therapeutic antibody development is one of the fastest growing areas of the pharmaceutical industry. Generating high-quality monoclonal antibodies against a given therapeutic target is very crucial for the success of the drug development. However, due to immune tolerance, some proteins that are highly conserved between mice and humans are not very immunogenic in mice, making it difficult to generate antibodies using a conventional approach. Methodology/Principal Findings In this report, the impaired immune tolerance of NZB/W mice was exploited to generate monoclonal antibodies against highly conserved or self-antigens. Using two highly conserved human antigens (MIF and HMGB1) and one mouse self-antigen (TNF-alpha) as examples, we demonstrate here that multiple clones of high affinity, highly specific antibodies with desired biological activities can be generated, using the NZB/W mouse as the immunization host and a T cell-specific tag fused to a recombinant antigen to stimulate the immune system. Conclusions/Significance We developed an efficient and universal method for generating surrogate or therapeutic antibodies against “difficult antigens” to facilitate the development of therapeutic antibodies.
