Figure Lengend Snippet: Compounds validation in cell-based assay. ( A–C) CD3 + T cells were treated with the specified compounds with or without TCR stimulation (anti-CD2/CD3/CD28 beads) at the indicated concentrations for 24 h. Cells were then stained with viability dye Ax700, followed by flow cytometry analysis of the percentage of FoxP3 in live CD4 + T cells. D) CD3 + T cells were treated with Compound 7 at the indicated concentrations for 48 h under TCR stimulation. The expression of Treg markers was assessed through flow cytometry analysis by gating on CD4 + FoxP3 + T cells. For TCR stimulation, anti-CD2/CD3/CD28 beads were added to the cells in a 1:2 ratio. E ) Tregs were treated with Compound 7 for 48 h and then cocultured with CellTrace Far Red-stained Teffs for 4 days. The proliferation of CD4 + and CD8 + Teffs was determined by measuring the percentage of CellTrace Far Red + cells among live cells, which was normalized to the Teff-only controls. Data are represented as mean ± SEM ( n = 3 healthy donors). * p < 0.5, ** p < 0.05, *** p < 0.005, **** p < 0.0005, 2-way ANOVA.
