Fig. 2From: Hyperactivation of proprioceptors induces microglia-mediated long-lasting pain in a rat model of chronic fatigue syndromeAppearance of ATF3-positive signal in L5 dorsal root ganglion (DRG) neurons during stress loading. a–f ATF3 immunoreactivity was first observed in the L5 DRG at day 2 (b). The number of the ATF3-positive cells increased as CS progressed (c–f). Arrows indicate ATF3-positive nuclei. Scale bar 200 μmBack to article page
