Intestinal microbiota gained attention due to its pleiotropic effect on intestinal barrier, nutrients metabolism and on immune system development and functions. Recent evidence pointed out a possible role of an altered gut microbiota composition in the pathogenesis and progression of several autoimmune disorders, occurring at gastrointestinal level or far apart. In thyroid autoimmune disorders, encompassing Hashimoto's thyroiditis, Graves' disease and thyroid-associated orbitopathy, the combined effect of environmental triggers and genetic predisposing background, lead to the loss of self-tolerance and to auto-aggressive damage, involving both cellular and humoral networks of immune system. This review is aimed at assessing the current knowledge about the studies published on the fecal microbiota composition in patients bearing thyroid autoimmune diseases. We further examined the reciprocal interaction between gut microbiota composition and the most used treatments for thyroid disorders.

The endometrial and vaginal microbiota have co-evolved with the reproductive tract and play a key role in both health and disease. However, the difference between endometrial and vaginal microbiota, as well as their association with reproductive outcomes in women undergoing frozen embryo transfer, remains unclear. 120 women who underwent in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) and whole embryo freezing were enrolled.

Plant growth-promoting bacteria (PGPB) are considered an effective eco-friendly biostimulator. However, relatively few studies have examined how PGPB affect the native bacterial community of major crops. Thus, this study investigates the impact of a PGPB consortium, comprising Pseudomonas sp.

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.

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.
