What this research studies

This project uses influenza-infected mice to measure immune responses and gene activity over time after exposure to estradiol. It also examines human lung epithelial cells and lung macrophages from male and female donors in the lab. The team will apply mathematical and network models to the experimental data to identify immune pathways that estradiol changes and how those changes differ by sex. Findings aim to link hormone levels to virus replication and disease severity across sexes.

Who could benefit from this research

Good fit: Ideal contributors would be people who can donate respiratory cells or tissue samples and are willing to provide basic health and sex-based information, typically recruited near the study site or through collaborating biobanks.

Not a fit: Patients seeking immediate new treatments for influenza are unlikely to benefit directly since the work is preclinical and focused on mechanisms rather than testing a therapy.

Why it matters

Potential benefit: If successful, the work could point to hormone-related mechanisms that explain sex differences in flu severity and suggest targets for more tailored treatments or prevention strategies.

How similar studies have performed: Previous research shows sex hormones can change flu outcomes and virus replication, but combining detailed time-course immune data with predictive mathematical models across mouse and human cells is relatively new.
