Figure 1From: Toll-like receptor 2 contributes to chemokine gene expression and macrophage infiltration in the dorsal root ganglia after peripheral nerve injury Macrophage infiltration in mouse DRGs was increased after peripheral nerve injury. (A) Upon L5 spinal nerve transection, L5 DRG tissues (ipsi- and contralateral) were obtained at various time points (n = 4 for each time point). DRG tissue sections were stained with anti-Iba-1 antibody. Scale bar: 50 μm. (B) The Iba-1-IR macrophage infiltration in ipsi- and contralateral DRGs of the injured peripheral nerve were quantified by measuring the intensity of Iba-1-immunoreactivity. Data are presented as mean ± SEM. (#, p < 0.05; ##, **, p < 0.01; #, ##, naïve (control) vs. 1, 3, 7, and 14 dpi mice; **, ipsilateral vs. contralateral).Back to article page
