Representative images of kainate-induced cobalt uptake in spinal cord slices from p14 mouse pups treated with i) saline, ii) TNFα and iii) TNFα + Tat-P4-(C5)2. Scale Bar: 100 µm. Quantification of cobalt positive (black soma) cells. Each data point represents the average 4-6 25 µm sections from a single 400 µm slice. Bars show means of 4-6 slices and error bars represent SEM. (one-way ANOVA followed by Bonferroni's multiple comparisons test, *P <0.05, **P<0.01).
