1. Introduction. The 10 14 microorganisms in the gut microbiome (GM) continuously engage in a dynamic dialog with the host cells.The GM is now viewed as an organ that contributes to digestive function, transforming complex food components such as fibers and carbohydrates into absorbable nutrients including short-chain fatty acids.Commensal bacteria produce factors that modulate the host.

The importance of the gut–brain axis in regulating stress-related responses has long been appreciated. More recently, the microbiota has emerged as a key player in the control of this axis, especially during conditions of stress provoked by real or perceived homeostatic challenge.

One reason that studying the impact of host genes on the gut microbiome is complicated is that the microbiome is strongly influenced by diet, environment, medications, and overall health status, which could mask any effects of the host’s genetics.6,8,20 Discovering clinically relevant associations may be possible only in study populations with.
