COMMD10-Guided Phagolysosomal Maturation Promotes Clearance of Staphylococcus aureus in Macrophages
Bibliographic record
Abstract
Staphylococcus aureus is a major cause of infectious disease. Liver Kupffer cells (KCs) are responsible for sequestering and destroying S. aureus through the phagolysosomal pathway. Proteins belonging to the COMMD family emerge as key intracellular regulators of protein trafficking, but the role of COMMD10 in macrophage-mediated S. aureus eradication is unknown. Here we report that COMMD10 in macrophages was necessary for its timely elimination, as demonstrated with two different S. aureus subspecies. In vivo, COMMD10-deficient liver KCs exhibited impaired clearance of systemic S. aureus infection. S. aureus-infected COMMD10-deficient macrophages exhibited impaired activation of the transcription factor EB, resulting in reduced lysosomal biogenesis. Moreover, S. aureus-initiated phagolysosomal maturation and function were significantly attenuated in COMMD10-deficient macrophages. Finally, expression of COMMD/CCDC22/CCDC93 complex, linked to phagolysosomal maturation, was reduced by COMMD10 deficiency. Collectively, these results support an important role for COMMD10 in instructing macrophage phagolysosomal biogenesis and maturation during S. aureus 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.
