Molecular mechanisms of bacterial invasion and colonization in the human gut microbiota

Project description

Bacterial invasion in the human gut

The human gut microbiota defends against pathogens and supports vital metabolic and immune functions. However, our understanding of how gut microbiota influences bacterial invasion and evolution remains limited due to the complexity of these interactions. Supported by the Marie Skłodowska-Curie Actions programme, the MICROINVADER project addresses this knowledge gap by investigating how the commensal bacterium Escherichia coli invades and evolves within different human gut microbiota compositions. Utilising an established in vitro gut simulator, the project aims to elucidate the molecular mechanisms behind bacterial invasion and colonisation. By validating findings through in vitro and in vivo experiments, MICROINVADER seeks to uncover insights that could inform strategies to manipulate gut microbiota, ultimately enhancing human health and well-being.

Objective

The human gut microbiota plays a critical role in safeguarding human health by defending against pathogens and supporting essential metabolic and immune functions. Nevertheless, our understanding of how the gut microbiota influences bacterial invasion and evolution within the human body is incomplete due to the complexity of these interactions. Furthermore, the specific mechanisms through which commensal bacteria, such as Escherichia coli, successfully invade and evolve in distinct human gut microbiota compositions remain unclear.
The MICROINVADER project aims to address this knowledge gap, utilizing an established in vitro gut simulator to investigate the precise mechanisms underlying the successful invasion of distinct human gut microbiota ecosystems by the commensal bacterium E. coli. Furthermore, MICROINVADER aims to characterize at the molecular level the processes that shape the evolution of invading strains in response to specific human gut microbiota compositions. Subsequently, MICROINVADER will validate these findings through in vitro and in vivo experiments, focusing on quantifying the selection strength acting on the genetic mechanisms that are crucial for bacterial invasion and colonization in different human gut environments.
By unveiling these novel mechanisms driving bacterial invasion and colonization within diverse human gut microbiotas, MICROINVADER seeks to provide critical insights that may have far-reaching implications for enhancing human health. Ultimately, MICROINVADER aims to contribute to our understanding of how to manipulate the gut microbiota in ways that promote and sustain overall well-being.
