“…12,111,116,[138][139][140] However, lower doses of chemotherapeutics, which cause an enhanced sensitivity to nociceptive stimuli, cause a degeneration or loss of IENF, similar to that observed in patients. 115,116,[141][142][143] One advantage of using animal models is that studies can be designed to determine whether this IENF loss is a cause or an effect of changes in neuronal sensitivity following chemotherapy treatment, although, to date, these studies have not been performed. The data from the animal models suggest that both increases and decreases in neuronal sensitivity occur following treatment with chemotherapeutics, depending on the endpoint measured and the dosing paradigm administered.…”
