Abstract
Activation of host phosphotyrosine phosphatase SHP-1 by Leishmania and its subsequent impact on tyrosine phosphorylation-based signaling cascades were shown to represent an important mechanism whereby this pathogen may alter host cell functions. Herein, we report that Leishmania-induced macrophage SHP-1 activity is necessary for its survival within phagocytes through the attenuation of nitric oxide-dependent and -independent microbicidal mechanisms. In vivo, Leishmania major infection, which footpad inflammation is mostly undetectable in SHP-1-deficient viable motheaten mice, was accompanied by increased inducible nitric oxide synthase and activation of neutrophils. These enhanced cellular activities were paralleled by a marked activation of signaling events usually negatively regulated by SHP-1. Overall, this study firmly establishes that modulation of the signaling terminator SHP-1 by Leishmania is essential for its installment and propagation.

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 it
