CCL2, NF-κB1, and C1Q in the dorsal horns (Wang et al., 2017), p53 and active caspase-3 in the DRG (Gao et al., 2018), Ccl3, Atf3, and Tgif1 in the spinal cord (Zhang and Yang, 2017) were separately considered to contribute to the generation of NP after SNI, chronic constriction injury (CCI), and spinal cord injury (SCI). Here, ATF3 is linked to spinal cord injury.
