The Dialogue between the Intestine-brain Axis: What is the Role of Probiotics?

Abstract

Introduction: Communication between intestine-brain axis is complex and uses different pathways. This communication forms a bidirectional axis whose equilibrium depends on the composition of the microbial community that inhabits the intestines. This ecosystem has a modulator role on the intestine-brain axis. Because of this, intestine-brain axis becomes a fascinating growing study area. The intestinal dysbiosis hurts the host's health and can lead to several psychiatric diseases. Aim: The present opinion described highlight an emerging theme in medicine, the interesting communication that is established between the intestine-brain axis. The function that intestinal probiotic microorganisms play in the health and disease of the host's has been gaining prominence. This is a promising area with an increasing number of studies which demonstrates its importance. Conclusion: In this context, the new class of probiotic microorganisms "psychobiotic" appear to have a significant role in the maintenance of eubiosis, revealing a new therapeutic potential for mental health.
