【摘要】 过氧化物酶体增殖剂激活受体(peroxisome prolifera-tion-activated receptors,PPARs)是由配体激活的核转录因子,属于核激素受体(nuclear hormone receptors)超家族。PPARs的激活可能对某些细胞的生长、分化甚至凋亡有重要影响。近年来的研究表明,PPARs具有神经保护作用,可减轻神经退行性疾病所致的脑组织损害,PPARs激动药可能用于阿尔采末病、帕金森病、缺血性脑中风及多发性硬化等神经退行性疾病的治疗。本文对PPARs在中枢神经系统的分布及功能、PPARs介导的信号途径及PPARs对阿尔采末病、帕金森病、缺血性脑中风及多发性硬化等神经退行性疾病的作用做一综述。更多还原

【Abstract】 Peroxisome prolifreator-activated receptors (PPARs) are ligand-activated nuclear transcription factors, members of nuclear hormone receptor superfamily. PPARs play critical roles in growth, proliferation and apoptosis of variety of cells. Recently, PPAR ligands have been reported to ameliorate neuronal damage in neurodegenerative diseases including Alzheim- ers disease, Parkinsons disease,cerebral ischemia and multiple sclerosis. PPAR agonists may have potential values in treatment of neurodegenerative diseases. In this paper, we reviewed recent findings on PPARs′ neuroprotective actions and their underlying mechanisms.更多还原
