    A Experimental design. Primary human CD8⁺ T cells were co-engineered with a lentiviral construct encoding the NR4A2-responsive synthetic promoter SP73 driving mCherry and constitutive EGFP to identify transduced cells, together with a retroviral NY-ESO-1–specific TCR. Engineered T cells were expanded and co-cultured with NY-ESO-1–expressing SK-MEL23 melanoma cells. B Quantification of mCherry⁺ T cells over time during co-culture. SP73-engineered T cells show progressive reporter induction, whereas control cells transduced with the control promoter SP01 (lacking NR4A2 binding sites) remain at baseline levels. Data represent mean ± SEM of n = 3 independent donors.

D Expression of NR4A2 and activation/dysfunction-associated markers in engineered T cells during co-culture. Data represent mean ± SEM of n = 3 independent biological donors. Statistical analysis was performed using one-way ANOVA with Tukey’s post hoc test. P values: CD39, P < 0.0001 for R0vsR2 and R0vsR4, P = 0.0048 for R2vsR4. NR4A2, P = 0.0375 for R0vsR2.
