In vitro effects of 17β-estradiol on the gene expression of pro-inflammatory mediators (ac), CXC chemokines (dg), and their receptors (hj) in the head kidney monocytes/macrophages. Cells were in vitro treated for 6 h with lipopolysaccharide (LPS, 30 μg/mL), 17β-estradiol (E2, 1 μM), or their combination (E2 + LPS). Changes in gene expression are shown as x-fold increase compared to unstimulated, treated with culture medium cells (CTR), and they were standardized for the housekeeping gene 40S ribosomal protein s11. Averages and S.E. (n = 4–5). Stars (*) indicate statistically significant differences between control (CTR) and treated cells (E2, LPS, and E2 + LPS) (*p ≤ 0.05, **p ≤ 0.001, ***p ≤ 0.0001), number signs (#) indicate statistically significant differences between LPS-treated cells (LPS) and E2- or E2 + LPS-treated cells (#p ≤ 0.05, ##p ≤ 0.001, ###p ≤ 0.0001), and ampersands (&) indicate statistically significant differences between E2- and E2 + LPS-treated cells (&p ≤ 0.05)
