配体-受体相互作用

Ligand-Receptor Interactions

Pierre Bongrand

摘要:

各种大分子之间特异性非共价相互作用的形成和解离在生物系统的功能中起着至关重要的作用。在过去的几年里,三条主要的研究路线使我们对这些重要现象的理解有了显著的提高。首先,基因工程和X射线晶体照相术的结合使得人们可以同时了解一系列或相关的配体-受体系统的精确结构和亲和力,这些配体-受体系统的区别在于几个定义明确的原子。第二,计算机能力和模拟技术的改进允许对现实大分子相互作用的扩展探索。第三,基于原子力显微镜、流体动力学流动、生物膜探针、光镊、磁场或柔性换能器的各种技术的同时发展产生了单配体受体键行为的直接实验信息。与此同时,明确定义的细胞模型的研究引起了生物学家对细胞膜受体的动力学和力学性质的兴趣。这篇评论的目的是描述这些进展,受益于一个很大程度上多学科的方法。

英文摘要:

The formation and dissociation of specific noncovalent interactions between a variety of macromolecules play a crucial role in the function of biological systems. During the last few years, three main lines of research led to a dramatic improvement of our understanding of these important phenomena. First, combination of genetic engineering and X ray cristallography made available a simultaneous knowledg of the precise structure and affinity of series or related ligand-receptor systems differing by a few well-defined atoms. Second, improvement of computer power and simulation techniques allowed extended exploration of the interaction of realistic macromolecules. Third, simultaneous development of a variety of techniques based on atomic force microscopy, hydrodynamic flow, biomembrane probes, optical tweezers, magnetic fields or flexible transducers yielded direct experimental information of the behavior of single ligand receptor bonds. At the same time, investigation of well defined cellular models raised the interest of biologists to the kinetic and mechanical properties of cell membrane receptors. The aim of this review is to give a description of these advances that benefitted from a largely multidisciplinar approach.
