Abstract
The investigations carried out during the last century related to the description of the Gut Microbiota (GM) suggest a concrete relationship between its composition and the health of the host. Its deregulation called intestinal dysbiosis has been associated with different types of gastrointestinal, metabolic, oncological and even psychiatric diseases. Numerous reports that have described the condition of dysbiosis in obesity stand out, both in animal and human models of different age groups and regions of the world. In turn, the composition of the microbiome has also been associated with the different comorbidities of obesity, postulating that MI has an influence on adipose tissue (AT) dysfunction, understanding that it corresponds to the main modulator of the pathogenesis of obesity. However, it is not yet possible to establish a plausible mechanistic explanation. Currently, the use of multi-omics technologies, together with the evaluation of physiological variables, could provide us with a better understanding of the question raised. In view of this, this review aims to review the latest advances in understanding the influence of the intestinal microbiota on AT and its contribution to the mechanisms related to the pathogenesis of obesity. Among the main mechanisms identified, the evidence reports physiological links between the composition of GM and the modulation of inflammation, intestinal permeability and adipogenesis. The pathways involved derive from the influence of intestinal dysbiosis on the action of short-chain fatty acids, claudins, macrophages, oligosaccharides, among others. The mechanisms involved, mainly studied in animal models, should be considered for evaluation in future longitudinal and experimental studies in humans in order to obtain a better understanding of the implication of each mechanism in the global pathogenesis of obesity.
期刊介绍:
Archivos Latinoamericanos de Nutrición (ALAN) is the official publication of the Sociedad Latinoamericana de Nutición (SLAN), for the dissemination of knowledge in the fields of food and nutrition, principally throughout the American Hemisphere. Articles in Spanish, English, Portuguese and French are accepted, both from the Society members and from nonmembers, in the following categories: 1. General articles (critical scientific reviews); 2. Research articles (originals); 3. Papers in applied nutrition (analytical results from intervention programs and discussion of reconmendations of practical application), and 4. Letters to Editor (short comments of general interest or about scientific facts and results previously published in Archives).
