研究目的:
|
本项目拟在揭示右美托咪定对于带状疱疹后遗神经痛(PHN)的治疗作用,以T细胞免疫功能及交感芽生现象为切入点,以髓系抑制细胞(Myeloid-derived suppressor cells,MDSCs)和p75为靶点,通过右美托咪定作用于PHN患者、大鼠及细胞,采用免疫组化、流式细胞术和基因工程等技术,揭示右美托咪定在PHN治疗中的双向作用及其机制,为PHN 治疗提供新策略。

Objectives of Study:
|
The purpose of this subject is to investigate the therapeutic effect of dexmedetomidine on postherpetic neuralgia (PHN) and to provide a new strategy for the treatment of PHN. This subject will use T cellular immune function and Sympathetic budding as breakthrough points, and myeloid-derived suppressor cells (MDSCs) and p75 as targets. This project aims to reveal the bidrectional effects and mechanisms of dexmedetomidine in PHN patients, rats and cells treatment by means of immunohistochemistry, flow cytometry and genetic engineering technology, etc.
