Prevention of mucosally induced uveitis with a HSP60‐derived peptide linked to cholera toxin B subunit
Bibliographic record
Abstract
Oral administration of the uveitogenic peptide (aa 336-351) derived from human HSP60 induced clinical and histological manifestations of uveitis in 65.8% (48/73) of Lewis rats. Uveitis was significantly decreased to 16.7% (11/66) in parallel experiments with the peptide linked to recombinant cholera toxin B subunit (rCTB), also given by mouth (chi(2)=34.2, p<0.0001). The protective efficacy between tolerized and immunized animals was 74.7%. Adoptive transfer of mesenteric lymph node cells from tolerized rats prevented the development of uveitis. A significantly higher proportion of regulatory CD4(+)CD45RC(low)RT6(+) subset of Th2 memory cells were found in the mesenteric lymph nodes (p<0.005) and spleens (p</=0.05) of tolerized rats without uveitis, as compared with immunized rats and uveitis. In situ hybridization studies of mesenteric lymph nodes and/or the uveal tract showed significant increases in IL-10 and TGF-beta mRNA but decreases in IFN-gamma and IL-12 mRNA in tolerized, as compared with immunized animals. Thus, the mechanism of tolerance, preventing the development of uveitis may involve a regulatory subset of memory cells and a shift from Th1 to Th2 and Th3 cytokines. We suggest that mucosally induced uveitis can be prevented by oral administration of the peptide-rCTB conjugate.

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.
