Western blot analysis showing effects of intravenous (IV) injection of interleukin (IL)-1β or 0.9% saline on expression of the transcription factor nuclear factor NF-κB (NF-κB) p65 subunit (A), inhibitor of κB (IκB-α, B), and c-Fos (C) in the hypothalamic paraventricular nucleus (PVN) of rats with a subfornical organ lesion (SFO-x) or a sham SFO lesion (SFO-s). Values are means ± SE and normalized to β-actin (n = 6 in each group). *P < 0.05 vs. SFO-s + IV saline; †P < 0.05 vs. SFO-s + IV IL-1β. Representative Western blots are shown above each bar.
