Vincristine is a chemotherapeutic agent that causes a peripheral neuropathy characterized by gait abnormalities, obstipation, changes in the perception of mechanical or vibration stimuli particularly in the hands and feet, as well as pain. Using a murine model, our work demonstrates that vincristine-induced pain involves release of interleukin-1ß from macrophages infiltrating peripheral nervous tissue via activation of the NLRP3 inflammasome. Accordingly, treatment with the anti-rheumatic IL1 receptor antagonist anakinra or the NLRP3 inhibitor MCC950 prevents development of vincristine-induced neuropathy. These findings have implications for prevention of chemotherapy-induced neuropathy in cancer patients.
