Abstract

Live bacterial therapeutics (LBTs) could reverse diseases by engrafting in the gut and providing persistent beneficial functions in the host. However, attempts to functionally manipulate the gut microbiome of conventionally raised (CR) hosts have been unsuccessful because engineered microbial organisms (i.e., chassis) have difficulty in colonizing the hostile luminal environment. In this proof-of-concept study, we use native bacteria as chassis for transgene delivery to impact CR host physiology. Native Escherichia coli bacteria isolated from the stool cultures of CR mice were modified to express functional genes. The reintroduction of these strains induces perpetual engraftment in the intestine. In addition, engineered native E. coli can induce functional changes that affect physiology of and reverse pathology in CR hosts months after administration. Thus, using native bacteria as chassis to "knock in" specific functions allows mechanistic studies of specific microbial activities in the microbiome of CR hosts and enables LBT with curative intent.

  • Deconjugation of taurine-conjugated BAs impacts colonization resistance against Klebsiella pneumoniae, colorectal cancer development, and metabolic disease.

    “For example, deconjugation of taurine-conjugated BAs has been shown to impact the establishment of colonization resistance against Klebsiella pneumoniae, the development of colorectal cancer and more recently metabolic disease43–45.”

    The Results (‘Engineered native E. coli bacteria affect host physiology’; page unavailable) report that BSH-expressing bacteria altered bile acids and improved insulin sensitivity in a mouse model of type 2 diabetes, supporting the metabolic-disease part of the sentence. The cited paper does not establish effects on colonization resistance against Klebsiella pneumoniae or colorectal cancer development. (LLM, conf=0.87)

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.
