Anti-cancer drugs, cisplatin, vincristine and taxol clinically induce toxic sensory as well as autonomic neuropathy. Administration of nerve growth factor (NGF) has been found to prevent experimental sensory neuropathies induced by these anti-cancer drugs, but the information about autonomic neuropathy is lacking. We developed an adult rat superior cervical ganglion (SCG) explant culture, which we treated with cisplatin, vincristine and taxol either in the presence or absence of NGF. The maximum length of regenerated neurites was shortened by cisplatin, vincristine and taxol in a dose-dependent manner. However cotreatment with NGF significantly promoted the regeneration of neurites in all drug-treated explants. The effect of NGF was clearly blocked by the anti-NGF antibody. These findings suggest that cotreatment of NGF prevents and reverses the toxic effects of the anti-cancer drugs on the sympathetic neurons.
抗癌药物顺铂、长春新碱和紫杉醇在临床上会诱发毒性感觉神经病变以及自主神经病变。已发现给予神经生长因子(NGF)可预防这些抗癌药物诱发的实验性感觉神经病变,但关于自主神经病变的信息尚缺。我们建立了成年大鼠颈上神经节(SCG)外植体培养体系,分别在有或无NGF的情况下用顺铂、长春新碱和紫杉醇对其进行处理。顺铂、长春新碱和紫杉醇均以剂量依赖的方式缩短了再生神经突的最大长度。然而,与NGF共同处理显著促进了所有药物处理外植体中神经突的再生。NGF的作用被抗NGF抗体明显阻断。这些发现表明,NGF共同处理可预防并逆转抗癌药物对交感神经元的毒性作用。
