Abstract:
In humans, the gut microbiota forms a complex ecosystem consisting of a vast number of bacteria, Archaea, fungi and viruses. It represents a major stimulus to the development of the immune system and many other physiological functions, so that it may shape the individual's susceptibility to infectious and immune-mediated diseases. The emergence of new '-omics' methods recently revolutionized the way we study the host-microbe interactions, but they also raised new questions and issues. In this review, we discuss the impact of these new data on the current and future therapies for chronic inflammatory diseases. We also outline the major conceptual, technical and interpretational issues that recently led to some misleading conclusions and discuss in brief the current research directions in the field.
