Abstract

Nanobodies are the products of an intriguing invention in the evolution of immunoglobulins. This invention can be traced back approximately 45 million years to the common ancestor of extant dromedaries, camels, llamas, and alpacas. Next to conventional heterotetrameric H2L2 antibodies, these camelids produce homodimeric nanobody-based heavy chain antibodies, composed of shortened heavy chains that a lack the CH1 domain. Nanobodies against human target antigens are derived from immunized animals and/or synthetic nanobody libraries. As a robust, highly soluble, single immunoglobulin domain, a nanobody can easily be fused to another protein, for example to another nanobody and/or the hinge and constant domains of other immunoglobulins. Nanobody-derived heavy chain antibodies hold promise as a new form of immunotherapeutics.

基于纳米抗体的重链抗体和嵌合抗体。
纳米抗体是免疫球蛋白进化过程中一项有趣发明的产物。这一发明可以追溯到大约 4500 万年前现存单峰驼、骆驼、美洲驼和羊驼的共同祖先。除了传统的异源四聚体 H2L2 抗体外,这些驼科动物还产生基于纳米抗体的同源二聚体重链抗体,这种抗体由缺少 CH1 结构域的缩短重链组成。针对人类目标抗原的纳米抗体来自免疫动物和/或合成纳米抗体库。纳米抗体是一种坚固、高溶解性的单个免疫球蛋白结构域,可以很容易地与另一种蛋白质融合,例如与另一种纳米抗体和/或其他免疫球蛋白的铰链结构域和恒定结构域融合。纳米抗体衍生的重链抗体有望成为一种新型免疫疗法。

期刊介绍: Immunological Reviews is a specialized journal that focuses on various aspects of immunological research. It encompasses a wide range of topics, such as clinical immunology, experimental immunology, and investigations related to allergy and the immune system. The journal follows a unique approach where each volume is dedicated solely to a specific area of immunological research. However, collectively, these volumes aim to offer an extensive and up-to-date overview of the latest advancements in basic immunology and their practical implications in clinical settings.
