嗅觉受嗅觉受体基因调控。
一项新的研究表明，鼻腔内数以百万计的嗅觉受体并不是随机分布的。
Millions of receptors in the nose's smelling organ aren't scattered at random, a new study says.
比如最致命的冈比亚按蚊，它和它的近亲最近得到了12中独特的嗅觉受体。
Anopheles gambia, for instance—the mostly deadly strain—and its close cousins have recently gained 12 unique olfactory receptors.
然而，人类鼻腔内约有400多种不同的嗅觉受体，能更有效地执行探测与识别有用信息的任务。
Humans have roughly 400 different kinds of receptors, however, making the business of sticking probes in noses and plucking out useful information more fruitful.
与其他动物将鼻子贴近地面相比，灵长类动物的嗅觉受体基因已所剩无几，这似乎支持了上述观点。
The relatively small repertoire of olfactory receptor genes in primates compared to animals that kept their noses closer to the ground seems to support this notion.
大约有300个人类嗅觉受体的伪基因，其相应基因在大鼠和小鼠的基因组内，仍是具有功能的基因。
For comparison, versions of about 300 human olfactory receptor pseudogenes are still functional genes in the genomes of rats and mice.
自1991年在动物中发现嗅觉受体基因以来，关于昆虫感受化学信息的周缘神经系统的分子和细胞机制方面的进展十分迅速。
Since the olfactory receptor genes identified in 1991, great achievements have been obtained on the molecular and cellular olfaction mechanism of insect.
文章介绍了嗅觉受体基因的结构、表达调控、分布、分子进化及其多态性研究进展， 并讨论了该基因与嗅觉功能和嗅觉障碍的关系。
The main gene related with olfaction was olfactory receptor (OR) gene. This review introduced the structure, expression regulation, distribution, molecular evolution and polymorphism of OR gene.
例如，研究表明，即使是短暂的气味刺激也会导致嗅觉上皮细胞中受体短暂的减少，这个过程被称为“受体疲劳”。
For example, studies show that even brief periods of odorant stimulation produce transient reductions in receptors in the olfactory epithelium, a process termed "receptor fatigue".
昆虫的嗅觉识别过程是非常复杂的，多种蛋白参与了这一过程，这些蛋白包括气味结合蛋白、气味降解酶以及气味受体等。
The olfactory behavior of insects is very complicated and involves many kinds of proteins, namely, odorant-binding proteins, odorant degrading enzymes and odor receptors etc.
一个嗅觉细胞表达一种气味受体，人类约有350个气味受体基因。
A olfactory cell can express one odorant receptor. There are about 350 odorant receptor genes in human.
气味分子与嗅觉神经元树突上气味受体的结合，参与了昆虫嗅觉识别的初始过程。
The initial steps in odor detection involve the binding of an odor to the odorant receptor displayed on dendrites of olfactory sensory neurons (OSNs).
