COVID Sensory Recovery

The sense of smell is maintained by regenerating olfactory sensory neurons (OSNs) from basal stem cells in the olfactory epithelium (OE), even during acute inflammation. Key mechanism for COVID-related smell loss recovery.

Otolaryngology expert discusses her pursuit of a cure for olfactory dysfunction, the science behind smell recovery, and research milestones redefining possibilities—hope for COVID anosmia patients.
