IL-1β protein expression in the corpus callosum of postnatal rats at 2 h and 2, 4, and 6 days after LPS exposure and their corresponding controls. Panel (a–f) show that IL-1β immunoreactive cells (b, e, red) clearly overlap lectin-labeled AMCs (a, d, green) in (c and f) in the corpus callosum of neonatal rats at 6 days after the LPS exposure and their corresponding controls. Panel (g) shows IL-1β (17 kDa) and β-actin (42 kDa) immunoreactive bands. Bar graph (h) shows significant increase in optical density of IL-1β following LPS injection in comparison with their matching controls. *P < 0.05, **P < 0.01. Scale bars: a–f 20 μm
