NIH-funded research Fellowship grant

Understanding how gut bacteria influence immune cells in the brain

Official title: Investigating the mechanism and role of the steady-state CXCR3-CXCL10 gut-microbiota-brain T cell axis

Funded at Yale University · NIH-11044978 · Data updated 2026-11-12

This study is looking at how the bacteria in our gut can change the way certain immune cells in the brain work, which could help us understand more about brain health and conditions that affect it.

Who could benefit from this research

Could help

Ideal candidates for this research would be individuals with conditions that may be influenced by gut-brain interactions, particularly those with neurological disorders.

Less likely to help

Patients with purely peripheral immune disorders unrelated to brain function or gut health may not benefit from this research.

What this research studies

This research investigates the unique immune response of the brain compared to the rest of the body, focusing on how gut bacteria affect T cells in the brain. It examines the role of specific immune cells, particularly CD4 T cells, and how their presence and function can be altered by changes in gut microbiota. By using mouse models, the study aims to uncover the mechanisms behind T cell trafficking to the brain and how these processes might influence neurological health.

Why it matters

Potential benefit: If successful, this research could lead to new insights into how gut health impacts brain function and immune responses, potentially informing treatments for neurological diseases.

How similar studies have gone: Previous research has shown promising results in understanding the gut-brain axis, but this specific investigation into steady-state conditions is relatively novel.
