The mechanism of bipolar disorder is unclear. Growing evidence indicates that gut microbiota plays a pivotal role in mental disorders. This study aimed to find out changes in the gut microbiota in bipolar depression (BD) subjects following treatment with quetiapine and evaluate their correlations with the brain and immune function. Totally 36 subjects with BD and 27 healthy controls (HCs) were recruited. The severity of depression was evaluated with the Montgomery-Asberg depression rating scale (MADRS). At baseline, fecal samples were collected and analyzed by quantitative polymerase chain reaction (qPCR). T lymphocyte subsets were measured to examine immune function. Near-infrared spectroscopy (NIRS) was used to assess brain function. All BD subjects received quetiapine treatment (300 mg/d) for four weeks, following which the fecal microbiota and immune profiles were reexamined. Here, we first put forward the new concept of brain-gut coefficient of balance (B-G), which referred to the ratio of [oxygenated hemoglobin]/( to ratio), to analyze the linkage between the gut microbiota and brain function. At baseline, the CD3 T cell proportion was positively correlated with log Enterobacter spp count, whereas the correlativity between the other bacteria and immune profiles were negative. Log B-G was positively correlated with CD3 T cell proportion. In subjects with BD, counts of , , , , and were higher, whereas the log (B/E) were lower than HCs (B/E refers to to ratio and represents microbial colonization resistance). After treatment, MADRS scores were reduced, whereas the levels of , , and B/E increased. The composition of the gut microbiota and its relationship to brain function were altered in BD subjects. Quetiapine treatment was effective for depression and influenced the composition of gut microbiota in patients. http://www.chictr.org.cn/index.aspx, identifier ChiCTR-COC-17011401, URL: http://www.chictr.org.cn/listbycreater.aspx.

The probiotic impact of microbes on host metabolism and health depends on both host genetics and bacterial genomic variation. is the predominant human gut commensal emerging as a next-generation probiotic. Although this bacterium exhibits substantial intraspecies diversity, it is unclear whether genetically distinct strains might lead to functional differences in the gut microbiome.

Background: Aging-related comorbidities are more common in people with human immunodeficiency virus (HIV) compared to people without HIV. The gut microbiome may play a role in healthy aging; however, this relationship remains unexplored in the context of HIV.
Methods: 16S rRNA gene sequencing was conducted on stool from 1409 women (69% with HIV; 2304 samples) and 990 men (54% with HIV; 1008 samples) in the MACS/WIHS Combined Cohort Study.

The complex microbial community residing in the human gut has long been understood to regulate gastrointestinal physiology and to participate in digestive diseases, but its extraintestinal actions and influences are increasingly recognized. This article discusses bidirectional interactions between the gut microbiome and athletic performance, metabolism, longevity and the ability of the gut-brain axis to influence cognitive function and mental health.

Unlabelled: The gut microbiota is closely associated with inflammatory bowel disease (IBD) and colorectal cancer (CRC). Probiotics such as (CB) or (AKK) have the potential to treat inflammatory bowel disease (IBD) or colorectal cancer (CRC). However, research on the combined therapeutic effects and immunomodulatory mechanisms of CB and AKK in treating IBD or CRC has never been studied.

Gut microbiota and their metabolites profoundly impact host physiology. Targeted modulation of gut microbiota has been a long-term interest in the scientific community. Numerous studies have investigated the feasibility of utilizing dietary fibers (DFs) to modulate gut microbiota and promote the production of health-beneficial bacterial metabolites.
