In vitro effects of 17β-estradiol on the production of nitric oxide (a) and on the arginase activity (b) in the head kidney monocytes/macrophages. Cells were in vitro treated for 24 h with either lipopolysaccharide (LPS, 30 μg/mL) or 17β-estradiol (E2, 1 μM) or their combination (E2 + LPS) or were treated with culture medium (CTR). 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), number signs (#) indicate statistically significant differences between LPS-treated cells (LPS) and E2- or E2 + LPS-treated cells (#p ≤ 0.05)
