Why some flu-infected lung cells die while others survive

Analysis of the heterogeneity of cell death responses in the influenza virus-infected cells

['FUNDING_R21'] · TUFTS UNIVERSITY BOSTON · NIH-11269200

This project looks at how lung cells respond differently to influenza so researchers can find ways to prevent the harmful cell death that leads to severe flu complications.

What this research studies

Researchers will examine infected lung cells to see which cells die and which survive, and why that happens. They will use detailed molecular analyses to track the gene activity and death pathways in individual infected cells. The team aims to identify surviving “persister” cells and the signals that separate helpful immune responses from damaging cell loss. Findings will guide lab efforts to protect lung function without stopping the body from clearing the virus.

Who could benefit from this research

Good fit: People hospitalized with severe influenza or those willing to donate respiratory or lung samples for research would be the most relevant participants or contributors.

Not a fit: People without influenza or those with only mild illness are unlikely to receive direct benefits from this project.

Why it matters

Potential benefit: If successful, this work could point to new treatments that protect lung cells and reduce severe lung failure from influenza.

How similar studies have performed: Previous laboratory studies have identified multiple cell-death pathways and surviving ‘persister’ cells in flu infection, but turning those findings into patient therapies remains largely untested.
