Investigating how gut bacteria change with age and affect health in monkeys.

Official title: A life course perspective on gut microbiome aging and health in a non-human primate model

Funded at University of Notre Dame · NIH-11020949 · Data updated 2026-11-12

This study is looking at how changes in gut bacteria as we age can affect our health, like frailty and diabetes, and it’s designed for older adults who want to understand how their gut health might influence their well-being as they get older.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals aged 65 and older who are interested in understanding the role of gut health in aging.

Less likely to help

Patients under the age of 65 or those with specific gut microbiome disorders may not benefit from this research.

What this research studies

This research explores the relationship between gut microbiome changes and aging by using a non-human primate model. It aims to identify how the functional capacities of gut bacteria evolve throughout the life course and how these changes relate to health outcomes such as frailty and diabetes. By focusing on the functional aspects of the microbiome rather than just the types of bacteria present, the study seeks to develop reliable markers for healthy aging. The research will involve tracking these changes over time to better understand their implications for health in older adults.

Why it matters

Potential benefit: If successful, this research could lead to new insights into how gut health influences aging and the development of diseases, potentially improving health outcomes for older adults.

How similar studies have gone: Previous research has shown promising results in understanding the gut microbiome's role in health, but this approach focusing on functional capacities in a life course perspective is relatively novel.
