Accumulating evidence indicates that the gut microbiota is intricately involved in the initiation and progression of human diseases, forming a multidirectional regulatory axis centered on intestinal microbiota. This article illustrates the challenges in exploring the role of the gut microbiota in inflammatory digestive diseases, such as metabolic dysfunction-associated steatotic liver disease (MASLD) and inflammatory bowel disease (IBD), and summarizes the existing microbiome-focused treatment strategies (probiotics, prebiotics, symbiotics, fecal microbiota transplantation, and bacteriophages therapy), emerging technologies (gut microbiome-on-a-chip and artificial intelligence), as well as possible future research directions. Taken together, these therapeutic strategies and technologies present both opportunities and challenges, which require researchers and clinicians to test the rationality and feasibility of various therapeutic modalities in continuous practice.

Microglia, the major population of brain resident macrophages, differentiate from yolk sac progenitors in the embryo and play multiple nonimmune roles in brain organization throughout development and life. Various microglia subtypes have been described by transcriptomic and proteomic signatures, involved metabolic pathways, morphology, intracellular complexity, time of residency, and ontogeny, both in development and in disease settings. Such macrophage heterogeneity increases with aging or neurodegeneration.

B cell depletion is an efficacious therapy for multiple sclerosis, but its long-term safety profile in the gastrointestinal tract has not been specifically studied. This is of importance because the gut is the largest reservoir of IgA in the body, which maintains gut homeostasis in part by regulating the composition of the gut microbiota. This was addressed by development of a prolonged B cell depletion model using human CD20 transgenic mice and B cell depletion with the anti-human CD20 antibodies rituximab, a humanized mouse monoclonal, and 2H7, the mouse precursor to ocrelizumab.

This work aims to (1) identify microbial and metabolic alterations and (2) reveal a shift in phenylalanine production-consumption equilibrium in individuals with HIV. We conducted extensive searches in multiple databases [MEDLINE, Web of Science (including Cell Press, Oxford, HighWire, Science Direct, IOS Press, Springer Nature, PNAS, and Wiley), Google Scholar, and Embase] and selected two case-control 16S data sets (GenBank IDs: SRP039076 and EBI ID: ERP003611) for analysis. We assessed alpha and beta diversity, performed univariate tests on genus-level relative abundances, and identified significant microbiome features using random forest.

The gut-kidney axis is the bidirectional relationship between the gut microbiota and the kidney function. Chronic inflammatory responses can impair kidney function and probiotics and postbiotics agents can have positive effects on gut health and kidney function by modulating inflammation through affecting autophagy signaling pathway. The aim of the current study was to evaluate the properties of our probiotic and postbiotics to improve kidney health by focusing the autophagy signaling pathway.
