Shikonin suppresses T cell proliferation and production of proinflammatory cytokines in vitro. (A) FACS-sorted CD3+ T cells from C57BL/6 mice were labeled with CFSE and then co-stimulated with anti-CD3/CD28 Abs and IL-2 in the absence or presence of shikonin or CsA for 4 days. Cell division was measured via FACS analysis. (B) The supernatant above was measured for cytokine production via ELISA. Shikonin suppressed IFN-γ and IL-17A production but increased IL-10 and TGF-β1 levels. Data of column graphs are presented as means ± SD (*P < 0.05 and **P < 0.01, n = 4 wells). One of three separate experiments is shown. (C) Potential cytotoxicity of shikonin on T cells was measured based on cell viability using CCK-8 assays. Data are presented as means ± SD from three independent experiments (*P < 0.05 and **P < 0.01, n = 4 wells).
