Expression of c-myc in Stimulated T Lymphocytes of the Helper/Inducer Phenotype Producing Lymphokine(s) Supporting Multilineage Colony Formation
Bibliographic record
Abstract
Phytohemagglutinin (PHA) renders human peripheral T lymphocytes competent to replicate their DNA and divide. The stimulation of peripheral T cells of the T4 phenotype by PHA, which appears to be a transcription-dependent event, leads to the production and release of lymphokines supporting proliferation and differentiation of human pluripotent stem cells (CFU-GEMMT). Supernatants of PHA-stimulated lymphocytes of the suppressor/cytotoxic phenotype (T8) failed to demonstrate reasonable activity to support the growth of CFU-GEMMT. Stimulation of T lymphocytes of the T4 but not of the T8 phenotype leads to an increased intracellular level of c-myc mRNA. This would be consistent with the c-myc gene product functioning as an intracellular mediator of the growth and lymphokine production response to PHA. Although the function of the c-myc gene product is not yet clear, it seems likely that it is involved in the control of cell proliferation. Such a contribution to control of cell proliferation by c-myc would probably be mediated by a family of genes inducing lymphokine production to stimulate proliferation of human pluripotent stem cells.

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.
