IL-17 does not induce cell death in NSCs, but decreases NSC proliferation. Cells were cultured in 96-well plates and treated with IL-17 for 48 h as described in Materials and Methods. (a) Plots depict LDH release in NSCs treated with different concentrations of IL-17; (b) Plots depict radioactivity in NSCs treated with different concentrations of IL-17. Data represent mean ± SE in triplicate samples from four independent experiments. NS, not significant.
