The regional distribution of resident immune cells shapes distinct immunological environments along the murine epididymis
Bibliographic record
Abstract
Summary/ Abstract The epididymis constitutes an important transition zone for post-testicular sperm maturation and storage. As the organ consists of a single convoluted duct, inflammation-associated tissue damage has a severe impact on fertility. In order to clarify the reasons for region-specific differences in the intensity of immune responses observed in a mouse model of acute bacterial epididymitis, we investigated the heterogeneity of resident immune cell populations within the epididymis under physiological conditions by scRNASeq analysis of extravascular CD45 + cells. 12 distinct immune cell subsets were identified, displaying substantial differences in distribution along the epididymis. Several distinct subsets of macrophages constituted the majority of these cells. Crucially, the proximal and distal regions showed striking differences in their immunological landscapes. These findings indicate that resident immune cells are strategically positioned along the epididymal duct, potentially providing different immunological environments required for sperm maturations and elimination of pathogens ascending the urogenital tract.

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.
