While cancer patients may have chemotherapeutics to thank for being cured of their malignancy, they are often left to suffer a disabling neuropathy induced by that same cancer treatment. This neuropathy, known as chemotherapy-induced peripheral neuropathy, or CIPN, is one of the most debilitating survivorship concerns for patients, with many citing hallmark symptoms of hyperalgesia, allodynia, and numbness, and subsequently reducing their dose or even ceasing treatment altogether. Investigations into this interplay between the antineoplastic activity of chemotherapeutic agents and the preservation of peripheral nerve health are therefore crucial for the development of CIPN treatment and prevention methods. Responding to need, current literature is inundated with varying preclinical models of CIPN. This chapter thus seeks to provide a detailed and reliable methodology for the induction and assessment of CIPN in mice, using a preclinical model that is both reproducible and translatable to several aspects of the clinical phenotype. Specifically, this chapter lays out a model for intermittent low-dose paclitaxel induction of CIPN in C57BL/6J mice, and a testing of this induction via von Frey filament mechanical hypersensitivity assays, a mechanical hyposensitivity (numbness) assay, and a cold-thermal allodynia assay (acetone test). These protocols can easily be adjusted to fit the needs of individual CIPN experiments, as stated throughout the chapter.
