Determination of CCL5 synthesis-related protein levels in astrocytes following stimulation with rHMGB1. (A) Western blot analysis of the phosphorylation of the ERK, JNK, P38 kinase and p65NF-κB proteins after astrocytes were treated with 0–2.5 µg/mL rHMGB1 for 24 h. (B-E) Quantification data are shown in (A). Quantities were normalized to endogenous β-actin. The experiments were performed in triplicate. The error bars represent the standard deviation (*P < 0.05, **P < 0.01, ***P < 0.001).
