Coprococcus eutactus screened from healthy adolescent attenuates chronic restraint stress-induced depression-like changes in adolescent mice: Potential roles in the microbiome and neurotransmitter modulation
Healthy gut bacteria Coprococcus eutactus reduces depression-like symptoms caused by stress in adolescent mice, possibly through changes in gut microbes and brain chemicals

Abstract
Genus Coprococcus significantly distinguished between healthy and unmedicated depressive adolescents.
- Transplantation of Coprococcus eutactus improved depression-like behaviors and reduced neuroinflammation in mice.
- Levels of neurotoxic neurotransmitters, such as 3-hydroxykynurenine and 3-hydroxyanthranilic acid, decreased in mouse brains following treatment with C.e.
- Treatment with C.e. altered the tryptophan metabolic pathway to favor serotonin signaling in the brain.
- In CRS mice, C.e. treatment enhanced recovery of goblet cells and mucus secretion, indicating a positive effect on gut health.
- The changes in gut microbiota included increases in beneficial genera such as Akkermansia and Roseburia after C.e. treatment.
