Different clinical course of experimental autoimmune encephalomyelitis (EAE) in neurointermediate pituitary lobectomized (NIL) plus adrenalectomized (ADX) Lewis and Wistar rats
Bibliographic record
Abstract
We have described that NIL Lewis rats develop mild signs of acute EAE with no changes in the HPA axis activity. Lewis and Wistar rats develop EAE, but differences in the HPA axis response to EAE exist between them. This suggests a different strain‐specific role of corticosterone (CO) in the immunoregulation of the EAE. Here we study the effects of CO and neurohypophyseal (NH) hormones deficiency (NIL) on the EAE. Rats from both strains were sham operated (SHAM) or NIL. Three weeks after surgeries rats were immunized with an encephalitogenic emulsion, and clinical course of EAE registered before and after ADX (performed at 27 day post‐immunization (DPI)). SHAM animals of both strains developed similar transient paralytic scores of EAE (10–20 DPI). In both strains, NIL induced decreased scores of the EAE. In Wistar SHAM ADX and NIL ADX groups no relapses of EAE occurred, whereas in Lewis SHAM ADX and NIL ADX groups a prompt and worse relapse of the EAE occurred, similar to the observed in the acute paralysis. Conclusions: 1) In NIL Wistar and Lewis groups, decreased severity of the EAE is under the NH hormones control, 2) In Wistar rats CO‐independent mechanisms protect against the EAE relapses, 3) In Lewis rats CO is required to protect against the EAE relapses, 4) Although NH hormones and CO participate in the immunopathology of the EAE it seems that they work through different mechanisms.

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.
