The NLR Protein NLRP6 Does Not Impact Gut Microbiota Composition
Bibliographic record
Abstract
NLRP6 is a Nod-like receptor expressed in the intestinal epithelium. Previous studies reported a protective role for NLRP6 against intestinal injury and colitis-associated carcinogenesis via the regulation and establishment of a healthy microbiota. However, these results were not obtained using littermate animals, leaving the possibility that the pro-colitogenic microbiota phenotype associated with knockout (KO) mice was stochastically acquired and genotype independent. Here, we analyzed the microbiota at three intestinal locations from Nlrp6 −/− and wild-type (WT) littermates, either co-caged or individually caged after weaning. Our results demonstrate that NLRP6 does not significantly influence the intestinal microbiota at homeostasis, and they support a previously reported sex-biased microbial community structure. Moreover, WT and Nlrp6 −/− littermate mice displayed comparable sensitivity to dextran sulfate sodium (DSS)-induced colitis, although increased sensitivity was noted in KO females. Our results clarify the role of NLRP6 in microbiota and colitis control, and they highlight the importance of analyzing littermate animals in such studies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
