Altered gut microbiota are assumed to be involved in the pathogenesis of irritable bowel syndrome (IBS). However, gut microbiota alterations reported in different studies are divergent and sometimes even contradictory. To better elucidate the relationship between altered gut microbiota and IBS, we characterized fecal microbiota of diarrhea-predominant IBS (IBS-D) patients and further explored

Neurological problems are prominent features of the syndrome, but the pathogenic mechanisms modulating its severity are still poorly understood. Gut microbiota was recently demonstrated to be altered both in animal models and humans with different neurodevelopmental Rett syndrome (RTT), a progressive neurological disorder mainly caused by mutations in MeCP2 gene, is commonly associated with gastrointestinal dysfunctions and constipation, suggesting a link between RTT’s gastrointestinal abnormalities and the gut microbiota. The human gut microbiota directly affects human health, and its alteration can lead to gastrointestinal abnormalities and inflammation.

Figure 1. Potential mechanism by which altered gut microbiota can result in metabolic syndrome. Flowchart of widely proposed mechanism by which excess caloric consumption promotes metabolic syndrome and its downstream diseases such as type 2 diabetes (T2D), cardiovascular disease (CVD), and nonalcoholic steatohepatitis (NASH).

The human gut microbiota directly affects human health, and its alteration can lead to gastrointestinal abnormalities and inflammation. Rett syndrome (RTT), a progressive neurological disorder mainly caused by mutations in MeCP2 gene, is commonly associated with gastrointestinal dysfunctions and constipation, suggesting a link between RTT's gastrointestinal abnormalities and the gut microbiota. Altered gut microbiota in Rett syndrome By Francesco Strati, Duccio Cavalieri, Davide Albanese, Claudio De Felice, Claudio Donati, Joussef Hayek, Olivier Jousson, Silvia Leoncini, Massimo Pindo, Daniela Renzi, Lisa Rizzetto, Irene Stefanini, Antonio Calabrò and Carlotta De Filippo Additional file 17: Figure S12. of Altered gut microbiota in Rett syndrome a) LDA scores of the most discriminant fungal taxa identified by LEfSe. Positive and negative LDA scores indicate the taxa enriched in healthy controls (HC) and Rett syndrome (RTT) subjects, respectively. Our hypothesis is that a dysbiotic gut in RTT patients could result in alterations of SCFAs that can worsen clinical symptoms by interacting at various levels (gut, brain, liver).

Metabolic syndrome is a group of obesity-related metabolic abnormalities that increase an individual’s risk of developing type 2 diabetes and cardiovascular disease. Here, we show that mice genetically deficient in Toll-like receptor 5 (TLR5), a component of the innate immune system that is expressed in the gut mucosa and that helps defend against infection, exhibit hyperphagia and develop

Rett syndrome (RTT), a progressive neurological disorder mainly caused by mutations in MeCP2 gene, is commonly associated with gastrointestinal dysfunctions and constipation, suggesting a link between RTT's gastrointestinal abnormalities and the gut microbiota. Gut microbiota was recently demonstrated to be altered both in animal models and humans with different neurodevelopmental disorders and/or epilepsy. By investigating gut microbiota in RTT cohorts, a less rich microbial community was identified which was associated with alterations of fecal microbial short-chain fatty acids. BACKGROUND: The human gut microbiota directly affects human health, and its alteration can lead to gastrointestinal abnormalities and inflammation. Rett syndrome (RTT), a progressive neurological disorder mainly caused by mutations in MeCP2 gene, is commonly associated with gastrointestinal dysfunctions and constipation, suggesting a link between RTT's gastrointestinal abnormalities and the Additional file 6: Figure S4. of Altered gut microbiota in Rett syndrome Multiple-rarefaction PCoA plots. Each PCoA replicate was optimally superimposed by Procrustes analysis on the master PCoA scatter plot (used in the main text). Given the immune pathway in the gut microbiota–brain axis, it is reasonable to hypothesize that altered bacterial and fungal biodiversity results in new interkingdom interactions that may be involved in the inflammatory process.

Here, we show that mice genetically deficient in Toll-like receptor 5 (TLR5), a component of the innate immune system that is expressed in the gut mucosa and that helps defend against infection, exhibit hyperphagia and develop Altered bacterial gut microbiota in RTT RTT is characterized by a dysbiotic gut microbiota showing an overall reduction of the microbial richness and diversity as well as an altered composition of the microbial community structure. Alterations of the gut microbiota do not depend on the constipation status of RTT subjects. Data on qualitative changes in the gut microbiota in IBS patients are lacking.
