From: Neuron-immune mechanisms contribute to pain in early stages of arthritis
Collagen-induced arthritis (CIA) is not associated with a significant astrogliosis in the dorsal horn of the spinal cord. Glial fibrillary acidic protein (GFAP) immunoreactivity in the dorsal horn of control (a) and CIA (b) rats on day 13 post-injection. c Quantification of GFAP intensity in the dorsal horn of CIA and control rats. Scale bar = 100 μm. In c, values are the mean ± SEM of 4 (days 4, 7 and 13) rats per group. No statistically significant differences (two-way ANOVA)
