热休克蛋白(HSP)是由Ritossa从经受热刺激后的果蝇唾液腺中发现的,因此取名HSP.但随着后来的大量研究发现,HSP是一切生物体在许多应激状态下(如高温、重金属、缺氧、乙醇、病毒及细菌感染等)合成增加的一种在进化上高度保守的细胞应激蛋白.HSP作为分子伴侣在蛋白质的折叠、稳定性、合成等方面发挥重要作用.晶状体混浊即白内障,是世界上最常见的致盲原因之一.大量的研究表明,白内障的发生与自由基的产生、氧化损伤、晶状体蛋白比例改变及晶状体上皮细胞的凋亡有直接关系.近年来的研究表明,晶状体能表达一系列的HSP,它们对维持晶状体的稳定和透明起到关键作用.本文就HSP与白内障的发生研究现状作一综述.
熱休剋蛋白(HSP)是由Ritossa從經受熱刺激後的果蠅唾液腺中髮現的,因此取名HSP.但隨著後來的大量研究髮現,HSP是一切生物體在許多應激狀態下(如高溫、重金屬、缺氧、乙醇、病毒及細菌感染等)閤成增加的一種在進化上高度保守的細胞應激蛋白.HSP作為分子伴侶在蛋白質的摺疊、穩定性、閤成等方麵髮揮重要作用.晶狀體混濁即白內障,是世界上最常見的緻盲原因之一.大量的研究錶明,白內障的髮生與自由基的產生、氧化損傷、晶狀體蛋白比例改變及晶狀體上皮細胞的凋亡有直接關繫.近年來的研究錶明,晶狀體能錶達一繫列的HSP,它們對維持晶狀體的穩定和透明起到關鍵作用.本文就HSP與白內障的髮生研究現狀作一綜述.

The hot shock proteins(HSP)were discovered by Ritossa in the fruit fly salivary gland after heat stimulation,giving the name HSP.In following comprehansive studies,it was recovered that HSP was a group of highly conservative cell stress proteins in all organisms.HSP are expressed under many stress conditions,e.g.in the presence of high temperature,heavy metal,oxygen deficit,ethyl alcohol and viral or bacteriae infections,etc.HSP,as the molecular companion,play a vital role in the folding,stability and synthesis of the protein.The lens opacification(cataract)is one of most common causes of blindness in the world.Various studies indicate that the occurrence of cataract is directly related to free radical production,oxidized damage,changes of the proportion of lens protein and apeptnsis of lens capsule epithelial cells,etc.Recent studies indicated that the lens expresses a series of HSP.They play a key role in maintaining the stability and transparency of the lens.This article is a summary of the relationship between the HSP and the occurrence of cataract.
