Where antibody-making cells live and how long they last in the nose

Defining mucosal plasma cell origin, residence, and longevity in the upper airway

NIH-funded research Duke University · NIH-11233303

What this research studies

This project maps antibody-secreting plasma cells that sit inside the nasal and olfactory tissues and are needed to block infections of the sense of smell. The team will determine when these local plasma cells take up residence, where exactly they live within the olfactory tissue, and how long they survive compared with antibody-producing cells in the bone marrow. They will use tissue analyses and cellular tracking methods to locate and characterize these cells and their antibody output. The goal is to understand why blood antibodies often fail to protect the olfactory mucosa so vaccines can be improved to give better local protection.

Who could benefit from this research

Good fit: Ideal candidates would be people willing to provide nasal or olfactory tissue samples or nasal swabs, including those with recent upper respiratory infections such as COVID-19.

Not a fit: People with conditions unrelated to the upper airway or who cannot provide nasal samples are unlikely to receive direct benefit from this research.

Why it matters

Potential benefit: If successful, this work could guide vaccines or therapies that create long-lasting antibody protection inside the nose and prevent reinfection and smell loss.

How similar studies have performed: Prior work shows blood antibodies often fail to protect the olfactory mucosa and that local plasma cells are necessary, but detailed timing, location, and longevity of these cells remain largely untested.
