The common cold virus, rhinovirus, usually causes mild symptoms, but in people with allergic asthma it can set off serious asthma attacks. The immune response walks a fine line between protecting the body and damaging it.

What they work on

  1. Identify pre-existing immune signatures that predict respiratory viral infection severity, using samples from a completed human model of repeated rhinovirus challenge together with a cohort of well-characterized allergic asthma patients.
  2. Build machine-learning pipelines that integrate high-dimensional immune-monitoring data, including spectral flow cytometry, cytokines and antibodies, with infection outcomes, and track how these features change across repeat infections.
  3. Use rhinovirus-specific peptide/MHC class II tetramers, reagents that capture T cells recognizing one viral fragment, with single-cell multi-omics to define the resting transcriptional state of rhinovirus-specific CD4+ T cells at the epitope level.
  4. Test how repeated viral exposure and chronic allergic inflammation remodel these virus-specific CD4+ T cells, comparing healthy challenged volunteers with allergic asthmatic patients.

More about the research

Higher numbers of virus-specific T cells, immune cells that recognize infected cells, are linked to less virus shedding in healthy people but to worse lung function in asthma. Almost nothing is known about how these cells persist over time, how repeated infections change them, or how long-standing allergic inflammation reshapes them. This project proposes that the immune landscape already present before infection, especially anti-viral T cells, determines how well a person is protected when the virus returns.

Why it matters

Rhinovirus is a major health burden and a common trigger of asthma attacks, yet there are no interventions that target protective immunity against it. Identifying the immune features that separate protection from harm could reveal targets for therapies that strengthen helpful anti-viral responses in people with allergic asthma without pushing the immune system toward the damaging responses that worsen lung function.
