Abstract

The mammalian gastrointestinal tract and associated mucosal immune system harbor a large repertoire of metabolites of prokaryotic and eukaryotic origin that play important roles in eukaryotic development and physiology. These often bioactive small molecules originate from nutrition- and environmental-related sources, or are endogenously produced and modulated by the host and its microbiota. A complex network of interactions exists between the intestinal mucosal immune system and the microbiota. This intimate cross-talk may be driven by metabolite secretion and signaling, and features profound influences on host immunity and physiology, including the endocrine, metabolic, and nervous system function in health and disease. Alterations in microbiome-associated metabolite levels and activity are implicated in the pathogenesis of a growing number of illnesses. In this review we discuss the origin and influence of microbiome-modulated metabolites, with an emphasis on immune cell development and function. We further highlight the emerging data potentially implicating metabolite misbalance with host-microbiome–associated disease.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Pathway enrichment comparisons showed anabolic functions predominating in responders including amino acid biosynthesis, and catabolic functions predominating in non-responders.

    “Comparisons of pathway enrichment across these groups showed changes in metabolic functions, with anabolic functions predominating in R including amino acid biosynthesis (Fig. 3E), which may promote host immunity (36), whereas catabolic functions predominated in NR (Fig. 3E, fig. S16, and table S7).”

    From Gut microbiome modulates response to anti-PD-1 immunotherapy in melanoma patients (2018) · cites this paper as [36]

    The citation is attached to the suggestion that amino acid biosynthesis may promote host immunity, not to the responder/non-responder comparison, which the citing sentence assigns to its own figures. In “Microbiome modulation of the gastrointestinal metabolite configuration” (page unavailable), the source describes tryptophan as immunomodulatory, but it does not establish that amino acid biosynthesis itself promotes immunity.

  • Several microbial metabolites, such as taurine, spermine, and histamine, can affect NLRP6 inflammasome activation in the gut and play an important role, if properly balanced, in host-microbial mutualism at the level of the intestine.

    “Several microbial metabolites, such as taurine, spermine, and histamine, can affect the NLRP6 inflammasome activation in the gut and play an important role, if properly balanced, in host-microbial mutualism at the level of the intestine (213).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
