In the presence of LPS NA inhibits CCL6 production by astrocytes. Astrocytes were incubated with control media, NA 10 μM or LPS 0.1 μg/ml alone or in combination with NA 10 μM for 24 hours. CCL6 levels in the media were assessed by ELISA. ***P <0.001 versus control; ΦΦΦ
P <0.001 versus LPS. Data are means ± SE of n = 12 replicates per group. C, control; CCL6, chemokine (C-C motif) ligand 6; ELISA, enzyme-linked immunosorbent assay; LPS, lipopolysaccharide; NA, noradrenaline; SE, standard error.
