Constitutive Immune Activity Promotes Tumorigenesis in Drosophila Intestinal Progenitor Cells
Bibliographic record
Abstract
Gut innate immune defenses control bacterial populations and protect the host interior from invasion. Although excess intestinal immune activity frequently promotes inflammatory illnesses, we know little about the consequences of chronic innate immune activity exclusively in endodermal gut cells of an otherwise normal animal. To address this question, we examined the consequences of persistent inflammatory signals in adult fly intestinal progenitor cells. We found that constitutive immune activity disrupts expression of homeostatic regulators such as Notch pathway components and induces hyperplasia throughout the gut. Consistent with these observations, we found that persistent immune signals interfere with progenitor cell differentiation and exacerbate the formation of Notch-dependent intestinal tumors. These findings uncover a link between constitutive immune activity and tumorigenesis in intestinal stem cells.

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.
