Blood cells are considered to be excellent ex vivo models for the characterization of diseases and in the determination of the beneficial or toxic effects of possible treatments. The results of numerous research projects over recent years, through which researchers have developed biomarkers of interest in different pathologies, make up the evidence behind this assertion.
In our bodies there are ten bacteria per human cell. This microbial richness plays a key role in our health and in the development of certain diseases. It was, however, a little understood role until the publication of research by Jeffrey I. Gordon, Director of the Center for Genome Sciences and Systems Biology at the University of Washington, who discovered the complex relationship between gut microbiota and nutrition and health, in addition to its impact on problems such as obesity.
