Mice fail to show mechanical pain hypersensitivity soon after partial ligation from the sciatic nerve (Abbadie et al., 2003). Also, mice overexpressing CCL2 in astrocytes exhibit enhanced nociceptive responses (Menetski et al., 2007). Though our data suggest that calcineurin-NFATc signaling contributes towards the development of neuropathic pain through improved CCR2 expression, calcineurin and NFATc are probably involved in the regulation of other target genes in neuropathic discomfort. As an example, it has been reported that COX-2 is an additional target gene of NFATc (Iniguez et al., 2000; Flockhart et al., 2008). We have shown that COX-2 is involved inside the induction, but not the maintenance, of neuropathic pain in rats subjected to spinal nerve injury (Zhao et al., 2000). Hence, enhanced expression of cytokines and cyclooxygenase-2 goods (e.g., prostaglandins) may possibly result from NFATc upregulation and play a vital function in the improvement of neuropathic discomfort soon after nerve injury. Altered gene expression in main sensory neurons triggered by nerve injury is regulated by lots of transcriptional components, for instance NF-kB, cyclic AMP response element binding protein, and NFATc. It has been shown that the expression of BK channels is regulated by the cyclic AMP response element binding protein (Wang et al., 2009). We located that treatment with FK-506 or 11R-VIVIT had no impact on the mRNA degree of BKa1 in the DRG, suggestingthat calcineurin-NFATc signaling does not regulate BKa1 expression altered by nerve injury. In summary, we identified that NFATc1-c4 expression in the DRG substantially elevated soon after nerve injury. Early inhibition of calcineurin-NFATc drastically attenuated CCR2 expression within the DRG along with the development of pain hypersensitivity after nerve injury. Our findings recommend that calcineurin-NFATc ediated nociceptive gene expression in the DRG contributes to the development of chronic neuropathic pain. This vital new information tremendously improves our understanding of the transcriptional mechanism involved in the transition from acute to chronic pain just after nerve injury.Authorship ContributionsParticipated in study design: Cai, Chen, Pan.
