Inflammation caused by neuropathy contributes to the development of neuropathic pain (NP), but the exact mechanism still needs to be understood. Peroxisome proliferator-activated receptor (PPAR), an important inflammation regulator, might participate in the inflammation in NP. To explore the role of PPAR in NP, the effects of PPAR agonist WY-14643 on chronic constriction injury (CCI) rats were evaluated. The results showed that WY-14643 stimulation could decrease inflammation and relieve neuropathic pain, which was relative with the activation of PPAR. In addition, we also found that the SIRT1/NF-B pathway was involved in the WY-14643-induced anti-inflammation in NP, and activation of PPAR increased SIRT1 expression, thus reducing the proinflammatory function of NF-B. These data suggested that WY-14643 might serve as an inflammation mediator, which may be a potential therapy option for NP.
