Parkinson's disease (PD) related pain can be assigned to either nociceptive pain or neuropathic pain, in which Transient receptor potential vanilloid 1 (TRPV1) has been demonstrated to play a pivotal role. Yet little research has examined possible involvement of TRPV1 in pain in PD. Here, we show that TRPV1 is highly expressed in PD and blocking TRPV1 can alleviate pain in PD. The level of TRPV1 in 6-OHDA induced semi mice model of PD was evaluated. The effect of TRPV1 and involved serotonin (5-HT) was also examined in the model. Unilateral injection of 6-OHDA in striatum significantly decreased thermal pain threshold and induced mechanical allodynia without changes in conditioned place preference. Immunostaining revealed that great increased expression in TRPV1 in the Vc of 6-OHDA lesioned mice compared with sham mice. TRPV1 sensitization was maintained by 5-HT/5-HT3A. In 6-OHDA-lesioned mice model of PD, TRPV1 sensitization might be implicated in the maintenance of behavioral hypersensitivity by enhanced descending 5-HT pain facilitation and dorsal horn 5-HT3AR mechanism.
