The Human Microbiome in Health and Disease

We are not alone in the little universe we call our body; rather we share it with complex communities of microbes. It is estimated that more than a trillion bacterial cells are present in the human gastrointestinal tract alone. Microbes also grow on our skin, in our mouth, and even up our nose; they are everywhere and collectively this microbiota is referred to as the human microbiome. These microbes are not just passive passengers — they shape our metabolism, health, and likely affect even life span. Simply put, the microbes within the human microbiome play a critical role in determining human health and disease.

This project launches two areas of research in microbiome science — using the human microbiome as a source of new drug leads and identifying metabolites that serve as biomarkers for early life diseases (asthma and autism) and aging diseases (such as Alzheimer’s disease).

The project leverages two UW-Madison population health cohort studies: the Children’s Respiratory Research and Environment Workgroup (CREW), which is tracking the early health and development of about 7,000 children; and the Wisconsin Longitudinal Study (WLS), one of the longest-running investigations of human health. In addition to these community samples, the microbiome will be studied in autism and neurodegenerative diseases through collaborators at the Waisman Center and the Alzheimer’s Disease Research Center.
