Figure 4.

Effect of C-phycocyanin on NF-κB activation in microglia. Microglia were cultured overnight in medium containing 10% of serum, which was replaced with serum-free medium before treatment with 100 μg/mL C-PC ± 100 ng/mL LPS. Cells were then processed for NF-κB p65 immunostaining. Experiments were performed 3 times and representative confocal images showing subcellular localization of p65 are shown. Scale bar, 10 µm.
