Multiple sclerosis (MS) causes long-lasting, multifocal damage to the central nervous system. The complex background of MS is associated with autoimmune inflammation and neurodegeneration processes, and is potentially affected by many contributing factors, including altered composition and function of the gut microbiota. In this review, current experimental and clinical evidence is presented for the characteristics of gut dysbiosis found in MS, as well as for its relevant links with the course of the disease and the dysregulated immune response and metabolic pathways involved in MS pathology. Furthermore, therapeutic implications of these investigations are discussed, with a range of pharmacological, dietary and other interventions targeted at the gut microbiome and thus intended to have beneficial effects on the course of MS.

Background: Despite prior observational studies suggesting a link between gut microbiota to Kawasaki disease (KD), these findings remain debated. This study aimed to assess the association between gut microbiota and KD on a genetic level using a two-sample Mendelian randomization (MR) analysis.
Methods: This two-sample MR analysis utilized summary statistics from the largest genome-wide association study meta-analysis on gut microbiota conducted by the MiBioGen consortium.

There are limited studies on the improvement of leaky gut with minor inflammation associated with various diseases. To explore the therapeutic potential of Lactiplantibacillus plantarum 22 A-3, a member of the Lactobacillus species, in addressing a leaky gut. Lactiplantibacillus plantarum 22 A-3 was administered to a leaky gut mice model with low dextran sulfate sodium concentrations.

Gut microbiota disruptions after allogeneic hematopoietic cell transplantation (alloHCT) are associated with increased risk of acute graft-versus-host disease (aGVHD). We designed a randomized, double-blind placebo-controlled trial to test whether healthy-donor fecal microbiota transplantation (FMT) early after alloHCT reduces the incidence of severe aGVHD. Here, we report the results from the single-arm run-in phase which identified the best of 3 stool donors for the randomized phase.

Rheumatoid arthritis (RA) is a complex autoimmune disease with growing evidence implicating the microbiota as a critical contributor to its pathogenesis. This review explores the multifaceted roles of microbial dysbiosis in RA, emphasizing its impact on immune cell modulation, autoantibody production, gut barrier integrity, and joint inflammation. Animal models reveal how genetic predisposition and environmental factors interact with specific microbial taxa to influence disease susceptibility.

Mice models serve as a valuable tool to study microbiome-immune system interactions. While the use of germ-free mice may represent the gold-standard method, antibiotic-based microbiome depletion provides a more cost-efficient and feasible system. The protocol here in presented provides a mild antimicrobial regime to deplete basal microbiota in 8-week-old C57BL/6 mice, aiming to ensure reproducibility in microbiota studies.
