Abstract
Obesity is a risk factor for cardio-metabolic and neurological disease. The contribution of gut microbiota to derangements of the gut-brain axis in the context of obesity has been acknowledged, particularly through physiology modulation by short-chain fatty acids (SCFAs). Thus, probiotic interventions and administration of SCFAs have been employed with the purpose of alleviating symptoms in both metabolic and neurological disease. We investigated the effects of four butyrate-producing bacteria from the Lachnospiraceae family on the development of metabolic syndrome and behavioural alterations in a mouse model of diet-induced obesity. Male mice were fed either a high-fat diet (HFD) or an ingredient-matched control diet for 2 months, and bacteria cultures or culture medium were given by gavage to HFD-fed mice every second day. Mice were assessed through a battery of metabolic and behaviour tests, and fluxes through the gut barrier and blood-brain barrier were determined using Dextran-based tracers. One of the administered bacteria from the Coprococcus genus, which produces butyrate and formate, afforded some degree of protection against the development of obesity and its complications. Results from this study, however, are insufficient to support brain health benefits of the bacteria tested. None of the bacteria modulated permeability through the gut or blood-brain barriers. Our results suggest health benefits of a bacteria from Lachnospiraceae family, and encourage further exploration of its use as probiotic.
期刊介绍:
Beneficial Microbes is a peer-reviewed scientific journal with a specific area of focus: the promotion of the science of microbes beneficial to the health and wellbeing of man and animal. The journal contains original research papers and critical reviews in all areas dealing with beneficial microbes in both the small and large intestine, together with opinions, a calendar of forthcoming beneficial microbes-related events and book reviews. The journal takes a multidisciplinary approach and focuses on a broad spectrum of issues, including safety aspects of pro- & prebiotics, regulatory aspects, mechanisms of action, health benefits for the host, optimal production processes, screening methods, (meta)genomics, proteomics and metabolomics, host and bacterial physiology, application, and role in health and disease in man and animal. Beneficial Microbes is intended to serve the needs of researchers and professionals from the scientific community and industry, as well as those of policy makers and regulators.
The journal will have five major sections:
* Food, nutrition and health
* Animal nutrition
* Processing and application
* Regulatory & safety aspects
* Medical & health applications
In these sections, topics dealt with by Beneficial Microbes include:
* Worldwide safety and regulatory issues
* Human and animal nutrition and health effects
* Latest discoveries in mechanistic studies and screening methods to unravel mode of action
* Host physiology related to allergy, inflammation, obesity, etc.
* Trends in application of (meta)genomics, proteomics and metabolomics
* New developments in how processing optimizes pro- & prebiotics for application
* Bacterial physiology related to health benefits
