The gut microbiota is closely linked with many gastrointestinal disorders, including inflammatory bowel diseases (IBD), diabetes, and colorectal cancer. However, many of the molecular mechanisms by which gut microorganisms and their metabolic products perturb host immunity are not yet understood. Both live cell and microbially-derived small molecule interventions have proven to prevent or ameliorate GI inflammation, but to a large degree, the therapeutic potential of targeted components of the microbiome has not yet been realized. In response to RFA-DK-15-012, we thus propose a “community research resource of identified members of the microbiome and factors they elaborate which modulate human physiology or pathophysiology related to... digestive diseases.” The Human Microbial Bioactives Resource (HMBR) will provide a comprehensive platform for discovery, validation, and early-stage translation of novel therapeutics derived from the microbiome: 1. An efficient end-to-end sampling and multi’omic profiling system for the host and microbiota in gastrointestinal disease. 2. Data from thousands of IBD microbiomes and tens of thousands of gut microbiome profiles, spanning dozens of datasets and meta-analyzing multiple countries, cohorts, and clinical centers. 3. Prioritized potentially bioactive elements of the gut microbiome in IBD, including A) microbial species and strains, B) microbial gene products (proteins, secreted peptides, biosynthetic gene clusters, etc.), and C) small molecules (e.g. metabolites or signaling molecules). 4. Screens for high-priority bioactives in vitro using mammalian cell and tissue models to characterize potential mechanisms of action and identify host-microbe-metabolite interactions. 5. Phenotypic readouts (cell population, cellular function-based, and preclinical IBD models) for successful bioactives in conventional and gnotobiotic mice to assess activity in vivo. 6. All HMBR data, protocols, computational tools, microbial isolates, compounds, cell lines, mice, screening results, and training material provided to the community through a unified web-based portal. 7. Exercising the resource with a driving biological application by verifying and characterizing novel modulators of the IL-10 anti-inflammatory and TNFα pro-inflammatory responses. This resource will be developed in the context of the Broad Institute, a leader in gut microbiome profiling and analysis in IBD; the Harvard School of Public Health, home to a rigorously monitored gnotobiotic mouse facility; and the University of Maryland, which currently supports the largest human microbiome resource worldwide in the form of the Human Microbiome Project 1 and 2 Data Coordinating Centers. Through this combination of investigators, environments, resources, and biological applications, we will establish and provide to the community the first platform of its kind for end-to-end microbiome therapeutic discovery and validation.

肠道微生物群与许多胃肠道疾病密切相关，包括炎症性肠病 疾病（IBD）、糖尿病和结直肠癌。然而，肠道的许多分子机制 微生物及其代谢产物干扰宿主免疫的机制尚不清楚。活细胞和 微生物衍生的小分子干预已被证明可以预防或改善GI炎症，但对 在很大程度上，微生物组的靶向组分的治疗潜力尚未实现。 作为对RFA-DK-15-012的回应，我们因此提出了一个“社区研究资源， 微生物组和因素，他们阐述了调节人体生理学或病理生理学相关... 消化系统疾病”人类微生物生物活性物质资源（HMBR）将提供一个全面的平台， 用于发现、验证和早期转化来自微生物组的新型疗法： 1.一个有效的端到端采样和多组学分析系统，用于宿主和微生物群， 胃肠道疾病 2.来自数千种IBD微生物组和数万种肠道微生物组的数据， 数十个数据集，并对多个国家、队列和临床中心进行荟萃分析。 3.
