The paper investigated how host genetics influence gut microbiome composition and disease susceptibility in active tuberculosis, combining analyses of gut microbiota with three independent human cohorts (6512 individuals) and supporting experiments in transgenic mice. It reports that patients with active TB have reduced abundance of core gut species, especially Akkermansia muciniphila, and that oral A. muciniphila or its metabolite palmitoleic acid inhibits TB infection by epigenetically inhibiting TNF-α, while an Ifnar1 rs2257167 G allele is associated with stronger IFN-I signaling, impaired colonization/abundance of A. muciniphila, reduced palmitoleic acid production, higher TNF-α, and more severe TB. A major limitation explicitly noted is that this work is a preprint that has not been peer reviewed. Relevance to endometriosis: the paper itself focuses on tuberculosis and gut microbiome–TNF-α pathways, and it does not explicitly discuss endometriosis or adenomyosis in the provided text, though it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract Both host genetics and gut microbiome have important effects on human health, yet how host genetics regulates gut bacteria and further determines disease susceptibility remains unclear. Here, we find that gut microbiome pattern of active tuberculosis (TB) patients is characterized by a reduction of core species found across healthy controls, particularly Akkermansia muciniphila (A. muciniphila). Oral treatments of A. muciniphila or palmitoleic acid, an A. muciniphila-derived metabolite, strongly inhibit TB infection through epigenetically inhibiting TNF-α. We use three independent cohorts comprising 6512 individuals and identify that single-nucleotide polymorphism rs2257167 “G” allele of type I interferon (IFN-I) receptor 1 (Ifnar1) contributes to stronger IFN-I signaling, impaired colonization and abundance of A. muciniphila, reduced production of palmitoleic acid, higher TNF-α, and much severer TB disease in humans and transgenic mice. Thus, host genetics are critical in modulating structure and functions of gut microbiome and gut microbial metabolites, which further determines disease susceptibility.

Oral treatments of \u003ci\u003eA. muciniphila\u003c/i\u003e or palmitoleic acid, an \u003ci\u003eA. muciniphila\u003c/i\u003e-derived metabolite, strongly inhibit TB infection through epigenetically inhibiting TNF-α. We use three independent cohorts comprising 6512 individuals and identify that single-nucleotide polymorphism rs2257167 “G” allele of type I interferon (IFN-I) receptor 1 (\u003ci\u003eIfnar1\u003c/i\u003e) contributes to stronger IFN-I signaling, impaired colonization and abundance of \u003ci\u003eA. muciniphila\u003c/i\u003e, reduced production of palmitoleic acid, higher TNF-α, and much severer TB disease in humans and transgenic mice. Thus, host genetics are critical in modulating structure and functions of gut microbiome and gut microbial metabolites, which further determines disease susceptibility.","manuscriptTitle":"An Ifnar1 allele impairs the colonization of gut bacteria \nand promotes tuberculosis","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2021-09-02 19:00:50","doi":"10.21203/rs.3.rs-847439/v1","editorialEvents":[],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"nature-metabolism","isNatureJournal":true,"hasQc":false,"allowDirectSubmit":false,"externalIdentity":"natmetab","sideBox":"Learn more about [Nature Metabolism](http://www.nature.com/natmetab/)","snPcode":"","submissionUrl":"","title":"Nature Metabolism","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"ejp","reportingPortfolio":"Nature Research","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"618fc6af-2160-4347-884f-500c596ca5a0","owner":[],"postedDate":"September 2nd, 2021","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[{"id":6917873,"name":"General Microbiology"},{"id":6917874,"name":"Infectious Diseases"}],"tags":[],"updatedAt":"2022-03-28T20:04:57+00:00","versionOfRecord":{"articleIdentity":"rs-847439","link":"https://doi.org/10.1038/s42255-022-00547-3","journal":{"identity":"nature-metabolism","isVorOnly":false,"title":"Nature Metabolism"},"publishedOn":"2022-03-14 04:00:00","publishedOnDateReadable":"March 14th, 2022"},"versionCreatedAt":"2021-09-02 19:00:50","video":"","vorDoi":"10.1038/s42255-022-00547-3","vorDoiUrl":"https://doi.org/10.1038/s42255-022-00547-3","workflowStages":[]},"version":"v1","identity":"rs-847439","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-847439","identity":"rs-847439","version":["v1"]},"buildId":"cBFmMYwuxLRRLfASyISRj","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}

Text is read by the "Ask this paper" AI Q&A widget below. Extraction quality varies by source — PMC NXML preserves structure cleanly, OA-HTML may include some navigation residue, and OA-PDF can have broken hyphenation. The publisher copy (via DOI) is the canonical version.

My notes (saved in your browser only)

Ask this paper AI returns verbatim quotes from the full text · source: preprint-html

Answers must be backed by verbatim quotes from this paper's full text. Hallucinated quotes are dropped automatically; if no verbatim passage answers the question, we say so. How this works

Citation neighborhood (no data yet)

We don't have any in-corpus citations linked to this paper yet. The paper's references may be in our DB but unresolved to ``paper_id`` (resolution happens at ingest when the cited DOI matches a row we already have). Run the cross-source citation reconcile pass to retry.
