Understanding how COVID-19 affects the sense of smell

Immune dysregulation mechanisms of persistent post-COVID19 olfactory dysfunction

NIH-funded research Brigham and Women's Hospital · NIH-10978693

This study is looking into why some people still can’t smell or taste well after recovering from COVID-19, and it aims to find new ways to help those who are experiencing these frustrating symptoms.

What this research studies

This research investigates the mechanisms behind the persistent loss of smell and taste in some individuals after recovering from COVID-19. It focuses on how immune cells infiltrate the olfactory system and disrupt the normal function of smell. By analyzing the specific immune responses and their effects on olfactory stem cells and sensory neurons, the study aims to identify potential targeted treatments for those suffering from these lingering symptoms. The research employs advanced techniques to characterize immune cell types and their impact on olfactory function.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals who have experienced persistent loss of smell or taste following COVID-19 infection.

Not a fit: Patients who have not experienced any olfactory dysfunction related to COVID-19 are unlikely to benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to effective treatments for patients experiencing long-term smell and taste dysfunction after COVID-19.

How similar studies have performed: While there has been some research into COVID-19 related symptoms, this specific investigation into immune dysregulation and its effects on olfactory function is relatively novel.
