Abstract

Background: For the past two decades there has been a growing appreciation of the role that the microbiota (the trillions of microorganisms within and on our bodies) plays as one of the key regulators of gut-brain function and has led to the appreciation of the importance of a distinct microbiota-gut-brain axis across the lifespan but especially during neurodevelopment.

Summary: The gut microbiota and its relevant metabolites interact with the immune and the central nervous systems during critical temporal windows of development. These critical developmental windows perinatally (during the first 1000 days) are susceptible timepoints for insults that can endure long-lasting effects on the microbiota-gut-brain axis. Accumulating evidence shows that a variety of factors can impact the microbiota in early life including mode of birth delivery, antibiotic exposure, mode of nutritional provision, infection, stress as well as host genetics. Additionally, sex differences occur in response to microbial manipulations in early life although the underlying mechanisms underpinning such effects remains elusive. Animal models have been essential in delineating a role of the microbiome in neurodevelopmental disorders ranging from autism spectrum disorder to attention deficit hyperactivity disorder. This mechanistic perspective should be supplemented with more translational studies to evaluate the applicability of findings from animal models to human subjects.

Key messages: Studies examining the translation of these effects from animal models to humans are currently ongoing with evidence for microbial modulation of neurocognitive development and neurodevelopmental risk increasing.

期刊介绍: ''Annals of Nutrition and Metabolism'' is a leading international peer-reviewed journal for sharing information on human nutrition, metabolism and related fields, covering the broad and multidisciplinary nature of science in nutrition and metabolism. As the official journal of both the International Union of Nutritional Sciences (IUNS) and the Federation of European Nutrition Societies (FENS), the journal has a high visibility among both researchers and users of research outputs, including policy makers, across Europe and around the world.
