Who could benefit from this research

Could help

Ideal candidates for future related studies would be individuals who have experienced persistent loss of smell and taste for many months after a COVID-19 infection.

Less likely to help

Patients whose smell and taste returned quickly after COVID-19, or those with other causes of smell loss, may not directly benefit from this specific research.

What this research studies

Many people experience a sudden loss of smell and taste with COVID-19, and for some, these problems can last for over a year. Current anti-inflammatory treatments haven't been effective for this long-lasting issue. This project will look closely at the immune cells and signals in the nose to figure out what's causing this persistent problem. By understanding these specific pathways, we hope to find new ways to help restore smell and taste.

Why it matters

Potential benefit: If successful, this work could lead to new, targeted treatments for individuals experiencing long-term smell and taste loss after COVID-19.

How similar studies have gone: Classical anti-inflammatory treatments have not been effective for this condition, suggesting this approach to identify specific immune pathways is novel.
