Article Synopsis
  • - The study focuses on how mosquitoes and other insects detect odors using specialized ion channel complexes made up of an odorant-binding subunit (OR) and a co-receptor subunit (Orco).
  • - Researchers used cryo-electron microscopy to determine the structures of two different mosquito odorant receptor complexes, finding an unexpected ratio of one OR to three Orco subunits.
  • - The findings show that when an odorant binds to the OR subunit, it is enough to open the channel pore, offering insights into how these receptors evolved and how insects sense odors.

Background: Insulin resistance is a critical cause of metabolic dysfunctions. Metabolic dysfunction is common in patients with cancer and is associated with higher cancer recurrence rates and reduced overall survival. Yet, insulin resistance is rarely considered in the clinic and thus it is uncertain how frequently this condition occurs in patients with cancer.

Mosquitoes rely on their sense of smell to find humans to secure a blood meal, transmitting deadly diseases with their bite. In this issue of Cell, De Obaldía and colleagues examine why mosquitoes bite some people more than others and report an association with the level of carboxylic acids in the human skin odor.

Olfactory systems must detect and discriminate amongst an enormous variety of odorants. To contend with this challenge, diverse species have converged on a common strategy in which odorant identity is encoded through the combinatorial activation of large families of olfactory receptors, thus allowing a finite number of receptors to detect a vast chemical world. Here we offer structural and mechanistic insight into how an individual olfactory receptor can flexibly recognize diverse odorants.
