Project Description Narrative:


Humans exist as "holobionts," living in a relationship with vast microbial ecosystems that colonize on skin and mucosal surfaces. Called the "microbiome," these microbes exist in everyone, with the vast majority found in the gastrointestinal (GI) tract. In a healthy person, these microbes co-exist peacefully, and are essential to good health. Yet, some microbes can be harmful and promote disease such as autoimmune and inflammatory diseases, obesity and neuropsychiatric disorders while also creating susceptibility to infection or poor responses to therapies such as vaccinations or chemotherapy.

Through this award, investigators aim to advance understanding of how microbiomes become established within a developing immune system, and how this process contributes to systemic health in order to inform further study and future therapies for prevention and care across varying diseases.
