Abstract

fetched live from OpenAlex

Objective:To investigate the immunoregulation effect of ovalbumin immune tolerance factors (OVA ITFs).Methods:Components that were smaller than 3 kD were isolated from the splenic lymphocytes lysates of OVA tolerance mice or naive mice,respectively,named as OVA ITFs or OVA ITFs conttrol.Naive BALB/c mice were divided into 5 groups,group A,B,C,D were injected i.v.by OVA ITFs,OVA ITFs control,splenic lymphocytes from OVA tolerant mice or PBS,respectively,group E as the blank control.The percentages of CD4+CD25+ T cell subpopulation from spleens before and after adoptive transfer were measured with flow cytometer;OVA specific lymphocyte responses were assessed by MTT assay.The levels of IL-10 and TGF-β1 in the culture supernatants were tested by ELISA kits.Results:For OVA ITFs or splenic lymphocytes from OVA tolerant mice,the percentages of CD4+CD25+ T cell subpopulation from spleens after adoptive transfer were raised significantly compared with that before adoptive transfer (15.32%±1.03% and 15.35%±0.62% vs 9.97%±1.38%,P0.05).The stimulation index of OVA-specific lymphocytes responses were 0.699±0.05 and 0.704±0.03 respectively,lymphocytes proliferation were suppressed significantly when compared with that of PBS control group(1.356±0.07,P0.05).The production of active TGF-β1 was showed of profound increases compared with that of PBS control group (129.15±6.14 and 106.71±2.89 pg/ml vs 52.82±3.68 pg/ml,P0.01),but IL-10 levels were not detectable.For OVA ITFs control,no significant differences were observed before and after adoptive transfer on either percentage of CD4+CD25+ T cell subpopulation,responses of OVA specific lymphocytes or IL-10 and TGF-β1 levels.Conclusion:OVA ITFs can transfer OVA specific immune tolerance to naive recipient mice.

Not 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.
