The microbiome-adipose tissue axis in systemic metabolism

Abstract

Abstract

The intestinal commensal microbiome is an important component of host health, in part by contributing an abundance of metabolites that gain access to the systemic circulation. The microbiome thereby influences the physiology of numerous organ systems outside the gastrointestinal tract. The consequences of this signaling axis between the intestinal microbiome and host are profound, in particular for the modulation of organismal metabolism. Here, we review recent examples whereby the intestinal microbiome influences host metabolism by influencing the biology of adipose tissue. We place a special emphasis on metabolite-driven pathways by which adipose tissue responds to alterations in intestinal microbial colonization. Given its accessibility for therapeutic interventions, the gut microbiome is an attractive relay module for the remote control of systemic metabolism.
