Fig. 2: Macrophages in the DRG, but not at the nerve injury site, are required for mechanical allodynia initiation.

From: Dorsal root ganglion macrophages contribute to both the initiation and persistence of neuropathic pain

a–e Effect of SNI followed by cannula injection with VEH or AP on immunostaining of GFP+ macrophages at the peripheral nerve (PN) ligature site (a–c) and DRG (d) (n = 3 per group) and on mechanical thresholds (e). Dashed lines in a and b denote ligature site; arrows point proximally. Scale bar: 50 µm. Gray shading indicates injection days. Data presented as mean ± SEM. Student’s t-test in c and d, and two-way repeated-measures ANOVA with Sidak’s correction in e. ***P < 0.001, NS nonsignificant compared with control. Source data are available as a Source Data file.
