Figure Lengend Snippet: CCL2, CCR2 and CD68 expression at 7 and 28dpi in the C7-8 ipsilesional dorsal root ganglia (DRG) normalized to housekeeping genes GAPDH and 18S in vehicle (n=17 7dpi, n=11 28dpi)- and INCB3344-treated (n=16 7dpi, n=13) rats, expressed as fold change over expression in naïve rats. CCL2 mRNA is significantly downregulated by 7 dpi in vehicle- and INCB3344-treated rats (***p<0.001, compared to naive) (A) and remains downregulated at 28dpi (***p<0.001 compared to naïve) (B) . CCR2 mRNA is significantly elevated at 7dpi (C) in both vehicle- and INCB3344-treated rats (*p=0.021 vehicle compared to naïve, *p=0.026 INCB3344 compared to naïve) and at 28 dpi (D) in both treatment groups (***p=0.001 vehicle compared to naïve, **p=0.004 INCB3344 compared to naive). By 7 dpi the expression of CD68 mRNA in the DRG (E) is significantly increased in vehicle (*p=0.039)- and INCB-treated rats (***p<0.001) compared to naive. At 28 dpi CD68 mRNA expression (F) is similarly significantly elevated for vehicle- and INCB-treated rats (***p<0.001 compared to naïve). Group averages ± SEM are represented as bars and individual data points as open circles.
Article Snippet: CCL2/MCP-1 levels in DRG tissue lysate were assayed using an ELISA kit (Abcam, MCP-1(CCL2) Rat ELISA kit #ab100777) as per the protocol and reported as pg/mg total protein.
