IFNG and Vogt-Koyanagi-Harada disease: Although human iPS-RPE cells failed to suppress the T cells (rather than T-cell stimulation) when we prepared fewer RPE cells for the assay (i.e., T cell:RPE ratio = 200:1, 100:1 or 50:1), iPS-RPE cells significantly suppressed the IFN-γ production of T cells from the PBMC of active uveitis patients with VKH disease (Figure 1C).
