Photomicrographs showing Isolectin B4 staining at 3 days after LPS injection in the somatosensory cortex. LPS was at different doses: (A) 0 ng, (B) 20 ng, (C) 50 ng, and (D) 100 ng. At 20 ng, ramified microglia were mainly seen (B) while round-shape phagocytic cells were the majority at 100 ng (D). Scale bar, 250 μm (40 μm for the inlets).
