Functional Interdependency between Intestinal Microbiota and Biological Clock

In the human body, practically all organs work in coordination in co-operation with other organs since they are regulated by neurological, hormonal, environmental signals. Scientists have lately found out another regulatory factor the intestinal microbiota. The quality and the quantity of microbiota are also dependent on many internal and external factors. The composition of the intestinal microbiota also affects those systems which are regulated by circadian rhythms, in other words, circadian rhythms and microbiota is a two-way street. In this review, we have discussed the cross-talk between these two regulators.
