Figure 2From: Satellite glial cell P2Y12 receptor in the trigeminal ganglion is involved in lingual neuropathic pain mechanisms in rats GFAP expression in TG after LNC. Photomicrographs of TG neurons encircled with GFAP-IR cells in the V3 branch region in naïve rats and those on day 3 after sham operation or LNC (A: naïve, B: sham, C: LNC). Time-course changes are shown in the mean relative number of TG neurons encircled with GFAP-IR cells on days 3, 9, 15 and 21 after sham operation or LNC. D: V1/V2 branch regions in TG, E: V3 branch region in TG. *: p < 0.05, **: p < 0.01, ***: p < 0.001 (n = 5 in each group, Student's t-test). Scale bars = 50 μm.Back to article page
