How airway T cells may stop respiratory viruses from spreading

Exploring the role of T cells in protection from respiratory virus transmission

NIH-funded research Emory University · NIH-11269194

This project looks at whether special immune cells in the nose and lungs called tissue-resident T cells can quickly block respiratory viruses from spreading and so help people avoid getting or passing on infections.

What this research studies

Researchers will use mouse and guinea pig models to study tissue-resident memory T cells that live in the airways. They will produce these cells by intranasal infection or vaccination and then use natural transmission models to see which T cell subsets stop viruses from spreading. The team will map the cell-intrinsic antiviral mechanisms and how these T cells communicate with airway epithelial cells to prevent viral propagation. Results are intended to inform design of vaccines or nasal therapies to boost airway immunity against influenza, coronaviruses, and other respiratory viruses.

Who could benefit from this research

Good fit: People at risk for respiratory viral infections (for example, influenza or COVID-19) are the long-term beneficiaries, although this project is preclinical and does not enroll patients directly.

Not a fit: Individuals seeking an immediate clinical treatment or those not exposed to respiratory viruses are unlikely to gain direct, short-term benefit from this laboratory-based research.

Why it matters

Potential benefit: If successful, this work could guide vaccines or nasal treatments that reduce the chance of catching or transmitting respiratory viruses.

How similar studies have performed: Prior animal studies have shown airway tissue-resident T cells can limit disease and reduce transmission, but applying these findings to human vaccines and therapies remains early-stage.
