摘要:

过氧化物酶体增殖物激活受体(peroxisome proliferator-activated receptors,PPAR)是核激素受体家族 中的配体激活的转录因子,有PPARα、PPARβ/δ及PPARγ 3 种亚型,其中PPARβ/δ控制许多细胞内的代谢过 程,包括长链脂肪酸、胆固醇和鞘脂的代谢等。PPARβ/δ作为一种转录因子,易被膳食脂质和内源性配体(如长 链饱和脂肪酸和多不饱和脂肪酸)以及某些脂质代谢产物激活,通过与视黄醇X 受体α(retinoid X receptor α, RXRα)的相互作用显示转录活性,显著调节糖、脂代谢、线粒体功能和细胞发育。尽管它在脑细胞及大脑的不同 区域中含量较丰富,但关于其在神经退化以及神经炎症中的作用仍知之甚少。近年来PPARβ/δ在神经退行性疾 病中的作用及其调控机制日益受到人们的关注,该文对PPARβ/δ的结构、功能以及其在阿尔茨海默病、帕金森 病、亨廷顿病以及多发性硬化症等神经退行性疾病中的作用进行综述。

Abstract:

Peroxisome proliferator-activated receptor (PPAR) is a ligand-activated transcription factor in the nuclear hormone receptor family,containing three different subtypes of PPARs,PPARα,PPARβ/δ and PPARγ. PPARβ/δ controls many intracellular metabolic processes,including the metabolism of long-chain fatty acids,cholesterol and sphingolipid. As a transcription factor,PPARβ/δ can be activated by dietary lipids and endogenous ligands (e.g. long-chain saturated and polyunsaturated fatty acids) as well as certain lipid metabolites. It displays transcriptional activity mainly through interacting with the retinoid X receptorα( RXRα) to regulate glucose and lipid metabolism,mitochondrial function,and cell growth. Despite of its high expression in brain cells and in different brain regions,its role in neurodegeneration and neuroinflammation remains poorly understood. In recent years,the role of PPARβ/δ in neurodegenerative diseases has attracted more and more attention. Based on the structure and biological function of PPARβ/δ,this paper reviews its role in the pathogenesis of neurodegenerative diseases such as Alzheimer’s disease,Parkinson’s disease,Huntington’s disease and multiple sclerosis.
