Summary
This work, produced under the NIH Integrative Human Microbiome Project (iHMP), presents a coordinated multi-omics investigation of how the human microbiome interacts with host biology across distinct disease-relevant conditions. By integrating data from metagenomics, metatranscriptomics, proteomics, and metabolomics, the project sought to move beyond descriptive cataloguing of microbial communities towards mechanistic understanding of host–microbiome co-regulation. The findings are likely to have broad implications for understanding how microbial function influences human health outcomes, including inflammation, metabolic dysregulation, and immune response.
UK applicability
Although conducted within a US cohort under NIH auspices, the mechanistic insights into host–microbiome interactions are broadly applicable to human biology and are relevant to UK nutrition, gut health, and microbiome research agendas, including work supported by the Wellcome Trust and UK Biobank initiatives.
Key measures
Metagenomic sequences; metatranscriptomic profiles; proteomic and metabolomic data; microbiome composition and functional activity across multiple body sites and time points
Outcomes reported
The study characterised host–microbiome interactions across multiple biological conditions using integrated multi-omics approaches, including metagenomics, metatranscriptomics, proteomics, and metabolomics. It likely reported associations between microbial community dynamics and host physiological states such as pregnancy, inflammatory bowel disease, or prediabetes.
