Article Abstract
Depression is a significant public health issue which exerts profound psychological and social impacts on both individuals and society. However, existing therapeutic strategies often exhibit limited efficacy. Accumulating evidence underscores the vital role of gut microbiota in the pathophysiology of depression through the microbiota-gut-brain (MGB) axis. This involves multiple mechanisms, including short-chain fatty acid (SCFA) metabolism, communication via the vagal nerve, regulation of the hypothalamic-pituitary-adrenal (HPA) axis, and immune-inflammatory interactions. This review provides a comprehensive review of the mechanisms through which gut microbiota influences depression via the MGB axis. It synthesizes recent achievements in this field and evaluates the potential of microbiome-targeted therapies for depression treatment. Furthermore, it outlines future research directions to establish a theoretical framework for novel therapeutic approaches and to foster the development of this area.

Cancer is a multifaceted disease driven by a complex interplay of genetic predisposition, environmental factors and lifestyle habits. With the accelerating pace of cancer research, the gut microbiome has emerged as a critical modulator of human health and immunity. Disruption in the gut microbial populations and diversity, known as dysbiosis, has been linked with the development of chronic inflammation, oncogenesis, angiogenesis and metastasis.

Introduction: Neonatal sepsis is a dysregulated immune response to bloodstream infection causing serious disease and death. Our review seeks to integrate the knowledge gained from studies of multiple molecular methods- such as genomics, metabolomics, transcriptomics, and the gut microbiome- in the setting of neonatal sepsis that may improve the diagnosis, classification, and treatment of the disease. Sepsis claims over 200,000 lives annually worldwide and remains a top 10 cause of infant mortality in the US.

Background: Increasing evidence suggests a potential role of the gut microbiota in Parkinson's disease (PD). However, the relationship between the gut microbiome (GM) and PD dementia (PDD) remains debated, with their causal effects and underlying mechanisms not yet fully understood.
Methods: Utilizing data from large-scale genome-wide association studies (GWASs), this study applied bidirectional and mediating Mendelian randomization (MR) to investigate the causal relationship and underlying mechanisms between the GM and PDD.

Short-chain fatty acids (SCFAs), primarily acetate (C2), propionate (C3), and butyrate (C4), are crucial microbial metabolites formed by the fermentation of dietary fibers by gut microbiota in the colon. These SCFAs, characterized by fewer than six carbon atoms, serve as an essential energy source for colonic epithelial cells and contribute approximately 10% of the body's total energy requirement. They are central to maintaining gut health through multiple mechanisms, including reinforcing intestinal barrier function, exerting anti-inflammatory effects, regulating glucose and lipid metabolism, and influencing host immune responses.

Background: Tripterygium glycoside (TG) has been reported to have the effect of ameliorating Alzheimer's disease (AD)-like symptoms in mice model. However, the underlying mechanism is largely unknown. This study aimed to investigate the potential mechanism of TG against AD by integrating metabolomics, 16s rRNA sequencing, network pharmacology, molecular docking, and molecular dynamics simulation.
