Scientists probe the role of archaea in the human microbiome
All multicellular living beings carry an unimaginably large number of microorganisms in and on their bodies. The microbiome, i.e. the totality of these microorganisms, forms a unit together with the host organism, the so-called metaorganism. This metaorganism has developed during the course of evolution by mutual exchange of its components. The interaction between the body and symbiotic microorganisms is of central importance for the healthy functioning of the metaorganism. From supporting the uptake of nutrients to protecting against pathogens, the microbiome performs vital tasks for the host organism. On the other hand, disturbances of the microbiome can cause various serious diseases, in humans for example diabetes, obesity or chronic inflammatory diseases. For several years, researchers worldwide have therefore been intensively studying the highly complex interactions of host organisms and microorganisms and their involvement in central life processes. One particular group of microorganisms has so far received little attention: the archaea,...
