Experiment Description

Research Overview
It has been suggested that living on board the International Space Station (ISS) likely causes immune dysfunction in the crew members, but the precise underlying mechanisms for this dysfunction is not well understood. Recent studies have indicated that imbalance in gut microbiota composition, or dysbiosis, resulting from a variety of environmental stresses, could lead to various disease statuses including immune dysfunction. Therefore, metagenomic analysis of the gut microbiota from crew members should result in better understanding of the immune dysfunction of crew members on the ISS. The Multi-omics analysis of human microbial-metabolic cross-talk in the space ecosystem (Multi-Omics) could identify candidates of bacterial and/or metabolic biomarkers for immune dysfunction which could be utilized for the development of the method to amend observed dysbiosis.

Applications

Space Applications
Biomarkers for immune dysfunction during the ISS flight could be useful for the health management of astronauts. Simple test kits for detection of the biomarkers are convenient for evaluating the immune dysfunction.

Earth Applications
Information on the effects and biomarkers could be applied to the fields of life sciences and technology.

With this proposal, researchers aim to understand the gut ecosystem, based on the host-gut microbiota interaction, of astronauts in space environment, especially focusing on immune dysfunction. Feces and/or saliva are collected non-invasively from astronauts and/or space-flown mice. These samples are subjected to metagenome, metabolome, gene expression profiling analysis to reveal the whole picture of changes in intestinal microbiota in response to space/ground environmental difference.
