在这里,我讨论脊椎动物嗅觉系统中受体布局的持久之谜。自从2004年诺贝尔奖授予阿克塞尔和巴克,以表彰他们发现了编码嗅觉受体的基因家族以来,我们的领域经历了一个黄金时代。尽管出现了文艺复兴,但对于任何感觉系统来说,最基本的问题之一--它的感受器阵列的解剖逻辑是什么?--仍然无法回答我们对嗅觉的看法!事实上,唯一引起广泛争议的假说起源于另一位诺贝尔奖得主禤浩焯爵士的沉思,该假说认为脊椎动物的鼻子根据其配体的“吸附”特性来组织其感受器。这一观点被称为“吸附”或“层析”假说,尽管存在争议,但仍得到了相当大的支持。在这里,我回顾了这一假说的历史--它的兴衰--并讨论了这一长期存在的想法的最新数据和未来前景,我将其历史比作神话中的凤凰。
Herein, I discuss the enduring mystery of the receptor layout in the vertebrate olfactory system. Since the awarding of the 2004 Nobel Prize to Axel and Buck for their discovery of the gene family that encodes olfactory receptors, our field has enjoyed a golden era. Despite this Renaissance, an answer to one of the most fundamental questions for any sensory system—what is the anatomical logic of its receptor array?—eludes us, still, for olfaction! Indeed, the only widely debated hypothesis, finding its origins in the musing of another Nobel laureate Sir Edgar Adrian, has it that the vertebrate nose organizes its receptors according to the “sorptive” properties of their ligands. This idea, known as the “sorption” or “chromatography” hypothesis, enjoys considerable support despite being controversial. Here, I review the history of the hypothesis—its rises and falls—and discuss the latest data and future prospects for this perennial idea whose history I liken to the mythical Phoenix.
