How the immune system responds to norovirus in healthy adults

Systems analysis of immune responses to Norovirus infection in a human challenge model.

NIH-funded research Cincinnati Childrens Hosp Med Ctr · NIH-11238084

This project will track early immune signals in healthy adults given a controlled norovirus exposure to see how those signals link to later antibody and cellular immunity.

What this research studies

You would be a healthy adult volunteer who receives a controlled norovirus exposure and gives blood and stool samples before and on days 1, 3, 5, and 14 afterward. Researchers will use high-throughput “omics” tests and measure cytokines and specific immune cells (including NK and CD14+ cells) in blood, and will also analyze stool transcripts. Samples come from two parallel challenge groups exposed to different norovirus strains and doses so investigators can compare responses. The goal is to find early immune patterns that predict who develops stronger antibody and cellular protection later.

Who could benefit from this research

Good fit: Healthy adults aged 21 years or older who are willing to participate in a controlled norovirus challenge and attend multiple clinic visits for blood and stool collection are ideal candidates.

Not a fit: People who are immunocompromised, have significant chronic health conditions, are under 21, or who do not want intentional exposure to norovirus would not be eligible or likely to benefit from participation.

Why it matters

Potential benefit: If successful, this work could help identify early immune markers that guide vaccine development and predict who will develop protective immunity after norovirus exposure.

How similar studies have performed: Human norovirus challenge trials have been done previously and have provided useful infection and immunity data, but applying deep transcriptomics to predict adaptive immunity is a newer approach.
