Concentration of cytokines in the liver at 2, 4, and 6 h postinjection of PBS, LPS, 1× μNETs, and 1× nNETs. Concentration measurements (as represented by symbols) for (a) IL-6, (b) IL-10, (c) TNF-α, and (d) MCP-1 are shown with the population mean (horizontal bars). Statistical significance of * (p < 0.05), ** (p < 0.01), and ***(p < 0.001) are indicated. Brackets with asterisks above them indicate statistically significant differences between the shown pairs.
