中文摘要: 抗肿瘤药泰素引起持续性触诱发痛,但机制不清。研究显示:趋化因子在神经病理性疼痛中起重要作用。我们预试验显示:泰素上调背根神经节趋化因子CCL2和CX3CL1;激活p38 MAPK和ERK1/2蛋白;美满霉素可以抑制泰素诱导触诱发痛和肿瘤坏死因子(TNF-α65289;上调。我们前期研究表明MAPK-TNF-α36890;路介导了神经病理性疼痛。我们推测:泰素通过上调趋化因子,激活MAPK通路,诱导TNF-α34920;达,最终介导触诱发痛。趋化因子CCL2、CX3CL1及趋化因子-MAPK-TNF-α36890;路是否介导泰素诱导触诱发痛,未见报道。本项目拟研究:①CL2和CX3CL1及其受体在泰素诱导触诱发痛中的作用;②#25506;讨两种趋化因子是否通过MAPK-TNF-α36890;路介导触诱发痛;③#25506;讨美满霉素是否通过干扰以上过程阻断触诱发痛。本项目的研究将有助于揭示泰素诱导触诱发痛的发生机制,为防治泰素诱导触诱发痛提供新的作用靶点。

英文摘要: The mechanism for Taxol-induced allodynia remains unclear. Study showed that chemokine play an important role in taxol-induced allodynia. our preexperimental results showed that application of taxol induced upregulation of CCL2, CX3CL1 and activated the p38 in DRG. Furthermore, minocycline prevented the taxol-induced allodynia and inhibited the upregualtor of TNF-αTherefore, we hypothesis that taxol activated p38 following the upregulation of chemokine, the activated p38 enhanced the synthesis and release of TNF-αthe increased TNF-αaused the centrental sensitivity and lead to the allodynia. so, in this present study, we will examined that 1: the role of chemokine and its receptor in taxol-induced allodynia; 2: whether chemokine mediated allodynia through MAPK-TNF-αignal pathway; 3: whether minocycline prevented taxol-induced allodynia through inhibition of MAPK-TNF-αignal pathway. This study would be important to development new therapeutic approaches for the treatment of taxol-induced allodynia.
