Bifidobacterium CECT 7765 modulates early stress-induced immune, neuroendocrine and behavioral alterations in mice.
2016
Emerging evidence suggests that there is a window of opportunity within the early developmental period, when microbiota-based interventions could play a major role in modulating the gut-brain axis and, thereby, in preventing mood disorders. This study aims at evaluating the effects and mode of action of Bifidobacterium pseudocatenulatum CECT 7765 in a murine model of chronic stress induced by maternal separation (MS). C57Bl/6J male breast-fed pups were divided into four groups, which were subjected or not to MS and supplemented with placebo or B. pseudocatenulatum CECT7765 until postnatal period (P) 21 and followed-up until P41. Behavioral tests were performed and neuroendocrine parameters …

Gut Microbiota and Risk of Developing Celiac Disease
2016
Gut microbiota shapes the development of the mucosal immune system and may provide protection against immune-mediated diseases. Celiac disease (CD) is a chronic inflammatory condition triggered by dietary gluten proteins, recently associated with gut microbiota alterations in cross-sectional studies comparing patients and controls. Whether or not these differences are causally related to the disease has yet to be elucidated, but evaluation of specific bacteria isolated from CD patients in experimental models suggests that they can promote an adverse response to dietary gluten, whereas other commensal bacteria can be protective. Genetic and environmental factors associated with increased CD …
Influence of gut microbiota on neuropsychiatric disorders
2017
The last decade has witnessed a growing appreciation of the fundamental role played by an early assembly of a diverse and balanced gut microbiota and its subsequent maintenance for future health of the host. Gut microbiota is currently viewed as a key regulator of a fluent bidirectional dialogue between the gut and the brain (gut-brain axis). A number of preclinical studies have suggested that the microbiota and its genome (microbiome) may play a key role in neurodevelopmental and neurodegenerative disorders. Furthermore, alterations in the gut microbiota composition in humans have also been linked to a variety of neuropsychiatric conditions, including depression, autism and Parkinson’s dis…
Plant sterols and human gut microbiota relationship: An in vitro colonic fermentation study
2018
Abstract Due to the preventive effect that plant sterols could have in relation to colon cancer and the scarce information available on plant sterols-gut microbiota interaction, we evaluate the sterols influence upon gut microbiota and viceversa. In vitro colonic fermentation using a residue from the in vitro digestion of a plant sterol-enriched beverage were used. Faecal sterols by GC–MS, and gut microbiota using DNA sequencing were determined. A higher plant sterols metabolism and lower for cholesterol in presence of plant sterols was occurred. Neutral plant sterols decreased and its metabolites increased during fermentation times. The global changes in microbial communities were associat…
A transdisciplinary educational experience at the Botanical Garden around scientific travelers
2019
In the framework of the transdisciplinary educational innovative project “Sciences and Arts” at the University of Valencia, we present here the design and outcome of an activity around the phenomenon of scientific travelers. It consisted in a scientific-literary tour through the Botanical Garden of the University of Valencia, that 100 students from the subjects “Natural Sciences for teachers” and “Literary training for teachers” attended. The activity was designed as a collaborative work in which scientific travelers served as a pretext to address six educational aspects that the students from each subject tackled in two different ways: from a more scientific than literary approach and vice…

Depletion of Blautia Species in the Microbiota of Obese Children Relates to Intestinal Inflammation and Metabolic Phenotype Worsening
2020
Cross-sectional studies conducted with obese and control subjects have suggested associations between gut microbiota alterations and obesity, but the links with specific disease phenotypes and proofs of causality are still scarce. The present study aimed to profile the gut microbiota of lean and obese children with and without insulin resistance to characterize associations with specific obesity-related complications and understand the role played in metabolic inflammation. Through massive sequencing of 16S rRNA gene amplicons and data analysis using a novel permutation approach, we have detected decreased incidence of Blautia species, especially Blautia luti and B. wexlerae, in the gut mic…
Intestinal Microbiota and Celiac Disease: Cause, Consequence or Co-Evolution?
2015
It is widely recognized that the intestinal microbiota plays a role in the initiation and perpetuation of intestinal inflammation in numerous chronic conditions. Most studies report intestinal dysbiosis in celiac disease (CD) patients, untreated and treated with a gluten-free diet (GFD), compared to healthy controls. CD patients with gastrointestinal symptoms are also known to have a different microbiota compared to patients with dermatitis herpetiformis and controls, suggesting that the microbiota is involved in disease manifestation. Furthermore, a dysbiotic microbiota seems to be associated with persistent gastrointestinal symptoms in treated CD patients, suggesting its pathogenic implic…
