Mammalians harbor trillions of millions of microorganisms, including bacteria, fungi, protozoa, archaea and virus. Most of these microorganisms constituent the commensal microbiota, which provides to the host access to essential vitamins, energy, and pathogen exclusion. In addition, it is now largely accepted that mammalian immunity is both directly and indirectly profoundly stimulated by exposure to microbiota and/or their molecular metabolites. Recently, several studies have defined a critical window early in life for the microbiota to shape the immune system establishing tissue homeostasis. Indeed, we have demonstrated that the maternal microbiota, during the gestation, shape the offspring immunity to prepare the newborn for the challenges that occurs from birth. Therefore, the microbiota and in particular, the maternal microbiota, are candidates to largely shape the development of the immune system.
Our projects aim to investigate the role of the microbiota in the development of the immune system in early life and the consequences in the health of infants and long-term effect, in the adult life. Our laboratory focuses in the impact of the microbiota in the development of tissue barriers during the gestation and the neonatal life, and in the immune responses of these organs in the context of infections, inflammatory diseases and auto-immune diseases.
