TREATMENT WITH ANTI-CD154 ANTIBODY AND DONOR-SPECIFIC TRANSFUSION PREVENTS ACUTE REJECTION OF MYOBLAST TRANSPLANTATION1
Bibliographic record
Abstract
BACKGROUND: Achieving immunological tolerance to transplanted myoblasts would reduce the adverse effects associated with the sustained immunosuppression required for this experimental therapeutic approach in Duchenne muscular dystrophic patients. METHODS: Mdx mice were transplanted with fully allogeneic BALB/c myoblasts in the tibialis anterior muscles. Seven days before transplantation (-7), host mice received 107 total donor spleen cells i.v. (donor-specific transfusion, DST) with 500 microg of anti-CD154 mAb i.p. on days -7, -4, 0, +4. RESULTS: Results showed a high level of dystrophin expression in 83, 60, and 20% of the mice 1, 3, and 6 months, respectively, after transplantation of myoblasts. No antibodies against the donor cells were produced up to 3 months after transplantation. However, abundant activated cytotoxic cells were present in muscles still expressing high percentage of dystrophin positive fibers. CONCLUSIONS: In conclusion, the DST + anti-CD154 mAb treatments effectively prolonged myoblast survival, but this treatment could not develop tolerance to complete allogeneic myoblast transplantation.

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.
