Making sense of scents
By Levi Gadye / Mon Mar 20, 2023
The human body is neurologically wired to sense the physical world. Cone cells in the retina detect specific wavelengths of light, while cells in the inner ear detect specific frequencies of sound, giving the brain a rich palette of sights and sounds to paint the human experience.
UCSF scientists have shown for the first time how an odorant, or smell molecule, activates a particular olfactory receptor, breaking a longstanding impasse in understanding olfaction—our connection to the world of scent.
The findings, which were published on March 15 in Nature, are poised to reignite interest in the science of olfaction with implications for food science, fragrances, and beyond. They also open the door to a deeper understanding of olfactory receptors, which constitute half of all G-protein coupled receptors, a class of proteins critical for a range of biological functions well beyond our senses.
“We’ve dreamed of tackling this problem for years,” said Aashish Manglik, MD, PhD, lead author on the study and faculty member in the UCSF School of Pharmacy’s Department of Pharmaceutical Chemistry. “We now have our first toehold, the first glimpse of how the molecules of smell bind to our odorant receptors. For us, this is just the beginning.”
Explore how Manglik and his colleagues made this breakthrough in olfactory science on UCSF News, featuring an interactive 3D model of an olfactory receptor bound to the odor molecule, propionate, which contributes to the smell of Swiss cheese.
