Abstract

The Aedes aegypti mosquito utilizes olfaction during the search for humans to bite. The attraction to human body odor is an innate behavior for this disease-vector mosquito. Many well-studied model species have olfactory systems that conform to a particular organization that is sometimes referred to as the "one-receptor-to-one-neuron" organization because each sensory neuron expresses only a single type of olfactory receptor that imparts the neuron's chemical selectivity. This sensory architecture has become the canon in the field. This review will focus on the recent finding that the olfactory system of Ae. aegypti has a different organization, with multiple olfactory receptors co-expressed in many of its olfactory sensory neurons. We will discuss the canonical organization and how this differs from the non-canonical organization, examine examples of non-canonical olfactory systems in other species, and discuss the possible roles of receptor co-expression in odor coding in the mosquito and other organisms.

蚊子和其他生物的非规范嗅觉前景：为什么要共同表达？

埃及伊蚊在寻找人类叮咬时会利用嗅觉。对人类体味的吸引是这种疾病媒介蚊子与生俱来的行为。许多经过深入研究的模式物种的嗅觉系统都符合一种特定的组织结构，这种组织结构有时被称为 "单受体对单神经元 "组织结构，因为每个感觉神经元只表达一种类型的嗅觉受体，这种受体赋予神经元化学选择性。这种感觉结构已成为该领域的标准。本综述将重点讨论最近的一项发现，即埃及蝇的嗅觉系统具有不同的组织结构，它的许多嗅觉感觉神经元共同表达多种嗅觉受体。我们将讨论规范组织及其与非规范组织的区别，研究其他物种非规范嗅觉系统的例子，并讨论受体共表达在蚊子和其他生物的气味编码中可能扮演的角色。

期刊介绍： Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following 11 areas are covered by Current Opinion in Insect Science. -Ecology -Insect genomics -Global Change Biology -Molecular Physiology (Including Immunity) -Pests and Resistance -Parasites, Parasitoids and Biological Control -Behavioural Ecology -Development and Regulation -Social Insects -Neuroscience -Vectors and Medical and Veterinary Entomology There is also a section that changes every year to reflect hot topics in the field. Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
