Epigenome - A mediator for host-microbiome crosstalk.

The interaction between the gut and its eventual trillions of microbe inhabitants during microbial colonization, represents a critical time period for establishing the overall health and wellbeing of an individual. The gut microbiome represents a diverse community of microbes that are critical for many physiological roles of the host including host metabolism. These processes are controlled by a fine-tuned chemical cross talk between the host and microbiota. Although the exact mechanisms behind this cross talk remains elusive, microbiota induced epigenetic mechanisms like DNA methylation and histone modifications may be key. This review presents our perspective on the epigenome as a mediator for host-microbiota cross talk, as well as methodology to study epigenetics, the role of dysbiosis in disease, and how the gut microbiome-host axis may be used in personal medicine.
