用于研究和临床用途的人单克隆mAb的生产与噬菌体展示技术的发展密切相关,该技术最初由Smith于1985年描述,并由其他小组进一步开发(例如,Winter,McCaffeine,Lerner,Barbas)。抗体噬菌体展示(APD)基于噬菌体(感染细菌的病毒)的基因工程和抗原引导的选择和噬菌体繁殖的重复轮次(Barbas,2001)。该技术允许体外选择几乎任何特异性的mAb,极大地促进了用于研究和临床诊断的试剂的重组生产,以及用于人类治疗用途的药物(例如,阿达木单抗,第一种完全人APD衍生的mAb)(Lee et al. 2007).由于在外部的抗体片段与编码噬菌体内展示的蛋白质的遗传信息之间建立了物理连接,APD还允许对抗原特异性mAb的遗传学和功能进行全面研究。这些特征使APD成为更好地理解免疫过程和人类疾病的有力工具,这些疾病涉及针对定义的(自身)抗原形成(自身)抗体。
The production of human monoclonal mAbs for research and clinical use is closely related to the development of phage display technology, initially described by Smith in 1985 and further developed by other groups (eg, Winter, McCafferty, Lerner, Barbas). Antibody phage display (APD) is based on genetic engineering of bacteriophages (viruses that infect bacteria) and repeated rounds of antigen-guided selection and phage propagation (Barbas, 2001). This technique allows in vitro selection of mAbs of virtually any specificity, greatly facilitating recombinant production of reagents for use in research and clinical diagnostics, as well as for pharmaceuticals for therapeutic use in humans (eg, adalimumab, the first fully human APD-derived mAb)(Lee et al., 2007).Because of a physical connection established between the antibody fragment on the outside and the genetic information encoding the displayed protein within the phage, APD also allows comprehensive studies of genetics and function of antigen-specific mAbs. These characteristics make APD a powerful tool to better understand immunological processes and human diseases that involve formation of (auto-) antibodies against defined (self-) antigens.
