  1. Gene expression and protein secretion of cytokines was analyzed in primary human hepatocytes (PHH), Kupffer cells (KC), liver sinusoidal endothelial cells (LSEC) and peripheral blood mononuclear cells (PBMC) exposure to indicated NAPs [5 μM]. Numbers indicate statistically significant and dose-related fold induction in cytokine gene expression (left, 6 h exposure) or cytokine secretion (right, 24 h exposure) relative to untreated cells. #, significant increase was only determined for 50 μM high dose treatment; *, not considered biologically relevant (see discussion); n.e., not evaluated.
