Impaired Protection against Mycobacterium bovis Bacillus Calmette-Guerin Infection in IL-15-Deficient Mice: J.Immunol.
Bibliographic record
Abstract
To investigate the potential role of endogenous IL-15 in mycobacterial infection, we examined protective immunity in IL-15-deficient (IL-15(-/-)) mice after infection with Mycobacterium bovis bacillus Calmette-Guerin (BCG) or recombinant OVA-expressing BCG (rBCG-OVA). IL-15(-/-) mice exhibited an impaired protection in the lung on day 120 after BCG infection as assessed by bacterial growth. CD4(+) Th1 response capable of producing IFN-gamma was normally detected in spleen and lung of IL-15(-/-) mice on day 120 after infection. Although Ag-specific CD8 responses capable of producing IFN-gamma and exhibiting cytotoxic activity were detected in the lung on day 21 after infection with rBCG-OVA, the responses were severely impaired on days 70 and 120 in IL-15(-/-) mice. The degree of proliferation of Ag-specific CD8(+) T cells in IL-15(-/-) mice was similar to that in wild-type mice during the course of infection with rBCG-OVA, whereas sensitivity to apoptosis of Ag-specific CD8(+) T cells significantly increased in IL-15(-/-) mice. These results suggest that IL-15 plays an important role in the development of long-lasting protective immunity to BCG infection via sustaining CD8 responses in the lung

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
