CD14 contributes to pulmonary inflammation and mortality during murine tuberculosis
Bibliographic record
Abstract
Toll-like receptors play an essential role in the innate recognition of micro-organisms by the host. CD14 is one of the extracellular adaptor proteins required for recognition of Gram-negative bacteria and possibly also Mycobacterium tuberculosis. Therefore, we intranasally infected wild-type (WT) and CD14 knock-out (KO) mice with virulent M. tuberculosis H37Rv. We found no differences in bacterial load in the main target organ lung up to 32 weeks after infection. From 20 weeks onward 57% of WT mice succumbed, whereas all CD14 KO mice survived. The improved outcome of CD14 KO mice was accompanied by reduced pulmonary inflammation; lung cell counts and percentage of inflamed lung tissue were reduced in CD14 WT mice. These data suggest that during chronic infection CD14 KO mice are protected from lethality caused by lung tuberculosis because of a reduction of the inflammatory response.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
