Truncated Cell Surface Markers Fused with Mutant Human Tmpk: Versatile Cell Fate Control Safety Cassettes for Lentiviral Vector Mediated Correction of Fabry Disease
Bibliographic record
Abstract
Lentivirus-mediated gene therapy has curative potential for a variety of disorders, however, insertional oncogenesis still remains a concern. One approach to increase safety of such treatment \nmodalities is to include a ‘cell fate control safety cassette’ in lentiviral vectors (LVs), enabling pharmacological control over the survival of gene-modified cells (GMCs). \nTwo novel LVs with engineered expression of truncated cell surface molecules (CD19 or \nLNGFR) fused to a ‘cell fate control’ gene (TmpkF105YR200A) were constructed. Results demonstrated these safety cassettes could be used to control the survival of GMCs in a murine xenogeneic leukemia models. For treatment of Fabry disease, a bicistronic LV containing the fusion safety element and \ntherapeutic α-galactosidase A was constructed. Transduction with this vector restored enzyme activity in Fabry patient’s fibroblasts. \nThese collective results demonstrate that this approach is sufficient to eradicate GMCs, and when combined with a corrective cDNA can provide therapeutic benefit for Fabry disease.

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.
