Fig. 3. At four weeks following l-BMAA injections, NF-κB (A–C, immunostaining), COX-2 (E–G, immunostaining), TNF-α (I–K, green color immunofluorescence staining, nuclei of all cells were stained with blue color Hoechst 33342) and CD68 (M–O, red color immunofluorescence staining) exhibited visible expression levels in the lumbar spinal cord, brain motor cortex and hippocampus, when compared with the normal control (D, H, L and P). BC: brain cortex. Scale bar = 100 μm.
