Effects of LPS, IL-1β and IL-6 treatments on the Cat C activity in BV-2 cells. The intracellular and extracellular activity of Cat C in BV-2 cells after six-hour treatment of LPS (10, 50 ng/mL), IL-1β (0.1, 10 ng/mL) and IL-6 (0.1, 10 ng/mL) were measured and showed in (A), (B) and (C), respectively. * or #: P < 0.05, **: P < 0.01, compared with untreated control. Data were expressed as mean + SEM from three independent experiments. Cat C, cathepsin C; LPS, lipopolysaccharide.
