Abstract
Strains of Roseburia inulinivorans, Bacteroides uniformis, and Eubacterium rectale have exhibited multi-pathway therapeutic efficacy against anxiety and depression-like behaviors in chronic unpredictable mild stress (CUMS) rats. However, the combined therapeutic effects of these strains remain to be elucidated. Behavioral tests showed that a mixture of these strains reduced anxiety and depression-like behaviors. 16S rRNA sequencing revealed that the mixtures decrease the relative abundance of potentially pathogenic bacteria within the gut microbiota. Furthermore, the mixture increased the levels of butyric, isobutyric, and isovaleric acids in the gut and decreased pro-inflammatory factors in serum. It also lowered diamine oxidase, histamine in brain tissue, increased DL-kynurenine, and reduced cortisol secretion by the hypothalamic pituitary adrenal axis. In summary, the mixture significantly alleviated anxiety and depression-like behaviors.
期刊介绍:
npj Biofilms and Microbiomes is a comprehensive platform that promotes research on biofilms and microbiomes across various scientific disciplines. The journal facilitates cross-disciplinary discussions to enhance our understanding of the biology, ecology, and communal functions of biofilms, populations, and communities. It also focuses on applications in the medical, environmental, and engineering domains. The scope of the journal encompasses all aspects of the field, ranging from cell-cell communication and single cell interactions to the microbiomes of humans, animals, plants, and natural and built environments. The journal also welcomes research on the virome, phageome, mycome, and fungome. It publishes both applied science and theoretical work. As an open access and interdisciplinary journal, its primary goal is to publish significant scientific advancements in microbial biofilms and microbiomes. The journal enables discussions that span multiple disciplines and contributes to our understanding of the social behavior of microbial biofilm populations and communities, and their impact on life, human health, and the environment.
