Aww thanks so much, Bridget! ☺️ I love working with you too! Very thankful to have such a stellar mentor. You are a fantastic cheerleader, brilliant thought partner, and teacher who brings out the best. I have learned so much from you 🫶

This is exciting because it suggests that the early life gut microbiome might shape functional brain development across early to middle childhood in ways that are relevant for emergence of anxiety and/or depression symptoms which children enter school age. Lots of possibilities for follow-up! 🥳

In sum, this study identifies prospective links between gut microbiome composition, brain functional connectivity networks, and internalizing (depression and anxiety) symptoms across early to middle childhood.

We found that one microbial profile, that included mostly microbes from the Clostridiales order and Lachnospiraceae family, was indirectly associated with internalizing symptoms through a brain signature characterized by alterations in connectivity within emotion-related networks.

Finally, we tested whether any microbiome features (microbial profiles or alpha diversity) were indirectly associated with internalizing symptoms via the brain signatures.
November 19, 2024 at 8:56 PM
In this study, we used sPLS to identify linear combinations of brain networks ("brain signatures") at age 6 that maximally covaried with internalizing symptoms at age 7.5 years, and then identified microbe abundances ("microbial profiles") at age 2 that maximally covaried with the brain signatures.

Studying the brain and gut microbiome together is challenging since both are very complex and high-dimensional. One possible solution is to use multivariate machine learning techniques, such as sparse partial least squares regression (sPLS).
