Hemolytic phospholipase<i>Rv0183</i>of Mycobacterium tuberculosis induces inflammatory response and apoptosis in alveolar macrophage RAW264.7 cells
Bibliographic record
Abstract
The metabolic pathway of phospholipids is one of the most important physiologic pathways in Mycobacterium tuberculosis, a typical intracellular bacterium. The hemolytic phospholipase lip gene (Rv0183) is one of 24 phospholipase genes that have been demonstrated to play critical roles in the metabolism of phospholipids in M. tuberculosis. Quantitative RT-PCR and flow cytometry were used to elucidate the immunological and pathogenic implications of the Rv0183 gene on the inflammatory response following persistent expression of Rv0183 in mouse alveolar macrophage RAW264.7 cells. Our results demonstrate that a time-course-dependent ectopic expression of Rv0183 significantly elevated the expression of IL-6, NF-κB, TLR-2, TLR-6, TNFα, and MyD88 in these alveolar macrophage cells. Furthermore, the persistent expression of Rv0183 induced RAW264.7 cell apoptosis in vitro. These findings demonstrate that the expression of Rv0183 induces an inflammatory response and cell apoptosis in the host cells, suggesting that Rv0183 may play an important role in the virulence and pathogenesis of M. tuberculosis infection.

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.
