“Mosquitoes possess 3 kinds of receptors that help in sniffing out people: odorant receptors (ORs), which detect alcohols and aldehydes; ionotropic receptors (IRs), which react to acids and amines; and as gustatory receptors, which discover the CO2 in our breath. Early research had actually suggested that each neuron reveals just one type of receptor, and that all the nerve cells revealing a particular receptor link to a dedicated olfactory nerve cluster (called a glomerulus) in the antennal lobe of the mosquitos brain.See “Researchers Discover What Attracts Mosquitoes to Humans”However, there had actually been inklings that mosquito olfaction might be more intricate, states Rockefeller Universitys Margaret Herre, a coauthor on the paper who was formerly a graduate trainee in Vosshalls lab. Now, researchers have discovered that mosquito nerve cells can reveal more than one receptor type and neurons with various receptors can be linked to the exact same glomerulus (bottom). Potters team recently reported that fruit flies likewise coexpress olfactory receptors.While mosquito olfaction appears to work differently than expected, “the guidelines for mosquito smell are still unwritten”, says Herre. While for Herre, mosquito olfaction could be a model for understanding how several receptors work together in one neuron, Duvall marvels how these unexpectedly multipurpose olfactory nerve cells impact mosquito behavior.Very likely, these reworded neuronal guidelines wont just apply to mosquito and fruit fly olfaction, includes Potter.

While for Herre, mosquito olfaction might be a design for understanding how multiple receptors work together in one neuron, Duvall wonders how these suddenly multipurpose olfactory neurons impact mosquito behavior.Very likely, these reworded neuronal rules will not just apply to mosquito and fruit fly olfaction, includes Potter.
