| Research Abstract |
Paclitaxel is one of the most commonly used antineoplastic drugs for the treatment of solid tumors. It is often associated with painful peripheral neuropathy. However, the mechanisms have been elucidated. In this study, we examined the involvement of L-serine in paclitaxel-induced peripheral neuropathy. This study suggests that a decrease in satellite cell-derived in the dorsal root ganglion contributed to paclitaxel-induced painful peripheral neuropathy. And intraperitoneal administration of L-serine improved both paclitaxel-induced mechanical allodynia/hyperalgesia. The findings of this study may lead to novel strategies for the treatment of paclitaxel-induced painful peripheral neuropathy in human patients with cancer.
