BTG3 and vitiligo: The CFSE flow cytometry results showed that both T-96 and Tofa suppressed CD8+ T cell proliferation in patients with vitiligo (Fig. 2D) as well as in healthy individuals (Additional file 1: Fig. S3C), and the combination of T-96 and Tofa showed stronger suppressive proliferation action in vitiligo patients (Fig. 2D).
