Paclitaxel is an extensively used chemotherapy antitumor drug and paclitaxel-induced peripheral neuropathy (PIPN) is one of the most common side effect. Rapamycin, originally used as an adjuvant drug for chemotherapy, has recently been found to possess potential neuroprotective activities. Our purposes of this study are to verify the effect of rapamycin on PIPN, which contributes to a new target for PIPN treatment. Mice were given paclitaxel or rapamycin with different injection methods. Paw withdrawal threshold was tested at different time points for mechanical sensitivity assessment. Administration of paclitaxel, both 2 mg/kg and 5 mg/kg, could induce mechanical hypersensitivity. 0.01 mg intrathecal injection of rapamycin showed the best effect on attenuate the mechanical hyperalgesia of PIPN. Intrathecal injection of only rapamycin would not induce the mechanical hyperalgesia while when rapamycin and paclitaxel were used together the mechanical hyperalgesia induced by paclitaxel could be attenuated. Paclitaxel could induce mechanical hyperalgesia in mice and rapamycin could attenuate such mechanical hyperalgesia of PIPN.
