Figure 1From: Involvement of the chemokine CCL3 and the purinoceptor P2X7 in the spinal cord in paclitaxel-induced mechanical allodynia Administration of paclitaxel causes activation of microglia in the SDH. (A) Threshold for withdrawal in response to mechanical stimulation to the hindpaw before and after injection of vehicle or paclitaxel (**P < 0.01, *** P < 0.001 vs. vehicle group, n = 6). (B) Immunofluorescence for Iba1, a marker of microglia, in the SDH of vehicle (control)- or paclitaxel-treated rats (Scale bar, 200 μm). Insets: high magnification images (Scale bar, 20 μm). (C) The number of microglia labeled with Iba1 per 6 × 105 μm in the SDH of paclitaxel-treated rats (n = 3, **P < 0.01, ***P < 0.001, vs. naïve control rats). Values are means ± s.e.m.Back to article page
