Differential Impact of Lymphocytes on Radiation Response in Autochthonous versus Transplant Sarcomas in Syngeneic Mice
Bibliographic record
Abstract
Abstract Preclinical studies in transplant tumor models showing high cure rates with combined radiotherapy (RT) and immunotherapy have rarely translated to clinical success, and studies in autochthonous tumor models are limited. We hypothesized that lymphocytes differentially affect RT response in transplant versus autochthonous tumor models. Here, we compared tumor onset and growth delay after 0 or 20 Gy for autochthonous versus transplant soft tissue sarcomas in Rag2 −/− mice lacking an adaptive immune system versus immune-intact Rag2 +/− mice. While time to tumor onset did not differ between Rag2 −/− and Rag2 +/− mice in the autochthonous model, transplant tumor onset was significantly slower in immunocompetent mice. No transplant tumors in Rag2 −/− mice or autochthonous tumors were cured by RT, whereas 30.4% of Rag2 +/− mice with transplant tumors were cured. These results highlight the importance of including autochthonous tumors as complementary model systems to study the interplay between the immune system and RT response.

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.
