Gut–brain link in teen and young adult opioid addiction

The adolescent microbiome-gut-brain axis as a potential target in opioid abuse disorders

NIH-funded research Oklahoma State University Stillwater · NIH-11335600

This project looks at whether changes in the gut microbiome and a common brain gene (BDNF Val66Met) influence how opioids affect adolescents and young adults.

What this research studies

From a patient point of view, researchers are using a mouse model that carries a common human BDNF gene variant to mimic adolescent oxycodone use and withdrawal. They will track how oxycodone changes gut bacteria and related chemicals, including short‑chain fatty acids and kynurenine metabolites. The team will test whether fecal microbiota transplants (FMT) can reverse opioid‑linked gut changes in mice with the BDNF variant. This work is an early step toward understanding whether the gut microbiome could be a target for treating opioid problems that begin in adolescence.

Who could benefit from this research

Good fit: Ideal future participants would be adolescents or young adults with opioid use or dependence who are interested in microbiome‑based approaches or in contributing samples for related studies.

Not a fit: People without opioid misuse or those outside the adolescent/young adult age range (and possibly those without the BDNF variant) are unlikely to gain direct benefit from this preclinical work.

Why it matters

Potential benefit: If successful, this could point to new microbiome‑based ways to prevent or treat opioid addiction that starts in adolescence.

How similar studies have performed: Prior animal studies link gut microbes to drug‑related behaviors and show FMT can change behavior in models, but applying this specifically to adolescent opioid use and the BDNF Val66Met variant is largely novel.
