Analysis of cytokines in cocultures of UniCAR-armed Tconvs and autologous Tregs. Cocultivation of UniCAR-endowed Tconvs and (a) TCR- or (b) UniCAR-activated Tregs was performed in the presence of 6 pmol αPSCA TM (a) at indicated Treg:Tconv ratios or (b) at a 1:1 ratio of both T cell populations. PC3-PSCA cells were added at a 5:1 UniCAR T cell to target cell ratio. After 48 h, cell-free supernatants were collected and analyzed for cytokine amounts using a MACSPlex Cytokine Kit. Concentration of indicated cytokines are shown as mean ± SEM for three individual donors. Statistical significance was calculated between individual UniCAR constructs using 1-way ANOVA with Bonferroni post hoc test (*p < .05, **p < .01, (a) with respect to UniCAR 28/ζ-engrafted Tconvs).
