Objective.
Postincision pain often occurs after surgery and is an emergency to be treated in clinic.
Electroacupuncture (EA) is a Chinese traditional treatment widely used to cure acute or chronic pain, but its mechanism is not clear.
Interleukin-10 (IL-10) is a powerful anti-inflammatory cytokine that shows neuroprotective effects in inflammation and injury in the CNS.
The present study attempts to reveal that IL-10 is crucial for EA analgesia on postincision pain.
Methods.
A model of incision pain was established in C57BL/6J mice.
The pain threshold was detected by behavioral test, and the expression of IL-10 and its receptor was detected by an immunohistochemical method.
C-fiber-evoked field potentials were recorded by in vivo analysis.
Results.
The mechanical allodynia induced by paw incision was significantly inhibited by pretreatment of EA in mice.
Intrathecal injection of IL-10 neutralizing antibody (2 µg/10 µL) but not intraplantar injection (10 µg/10 µL) reversed the analgesia of EA.
The upregulations of IL-10 mRNA and protein were induced by EA at 6 h and 1 d after incision, respectively.
Spinal long-term potentiation (LTP), a substrate for central sensitization, was also suppressed by EA with IL-10.
IL-10 recombinant protein (1 µg/10 µL, i.t.) mimicked the analgesia of EA on mechanical allodynia and inhibition on the spinal LTP.
Posttreatment of EA after incision also transitorily relieved the mechanical allodynia, which can be blocked by spinal IL-10 antibody.
IL-10 and its receptor, IL-10RA, are predominantly expressed in the superficial spinal astrocytes.
Conclusions.
These results suggested that pretreatment of EA effectively prevented postincision pain and IL-10 in spinal astrocytes was critical for the analgesia of EA and central sensitization.
