Selectivity of odorant receptors in insects
Insect olfactory receptors (ORs) detect chemicals, shape neuronal physiology, and regulate behavior. Although ORs have been categorized as "generalists" and "specialists" based on their ligand spectrum, both electrophysiological studies and recent pharmacological investigations show that ORs specifically recognize non-pheromonal compounds, and that our understanding of odorant-selectivity mirro...
متن کاملOdorant and Pheromone Receptors in Insects
Since the emergence of the first living cells, survival has hinged on the ability to detect and localize chemicals in the environment. Modern animal species ranging from insects to mammals express large odorant receptor repertoires to detect the structurally diverse array of volatile molecules important for survival. Despite the essential nature of chemical detection, there is surprising divers...
متن کاملOdorant Receptor Desensitization in Insects
Insects and other arthropods transmit devastating human diseases, and these vectors use chemical senses to target humans. Understanding how these animals detect, respond, and adapt to volatile odorants may lead to novel ways to disrupt host localization or mate recognition in these pests. The past decade has led to remarkable progress in understanding odorant detection in arthropods. Insects us...
متن کاملTuning Insect Odorant Receptors
Citation: Wicher D (2018) Tuning Insect Odorant Receptors. Front. Cell. Neurosci. 12:94. doi: 10.3389/fncel.2018.00094 Among the insect olfactory receptors the odorant receptors (ORs) evolved in parallel to the onset of insect flight. A special property of this receptor type is the capability to adjust sensitivity of odor detection according to previous odor contacts. This article presents a cu...
متن کاملDiversity of odorant-binding proteins and chemosensory proteins in insects.
Odour and pheromone perception occurs through a complex series of events, many aspects of which have been elucidated in the most recent years. The discovery of membrane-bound olfactory receptors, both in vertebrates and in insects, and their functional expression in heterologous systems have shown that they can be directly activated by odorant and pheromone molecules. Although a pathway of sign...
