脂聯素(Adiponectin/ADPN) 是脂肪細胞分泌的一種內源性生物活性多肽或蛋白質。脂聯素是一種胰島素增敏**(An Insulin-sensitizing Hormone),能改善小鼠的胰島素抗性(Insulin resistance)和動脈硬化癥;對人體的研究發現,脂聯素水平能預示II型糖尿病和冠心病的發展,并在臨床試驗表現出抗糖尿病、抗動脈粥樣和炎癥的潛力。
脂聯素不僅由脂肪細胞分泌,骨骼肌、內皮細胞、心肌細胞也可分泌;其由染色體3q27的apM1基因編碼,該基因由3個外顯子和2個內含子組成。脂聯素的相對分子質量為30000,與補體C1q結構相似,又稱為Arcp30、AdipoQ、apM1、GBP28;同時,它還屬于可溶性膠原超家族,與膠原VIII和X、補體C1q和腫瘤壞死因子(tumornecrosisfactor,TNF)家族具有結構同源性。 [1]
脂聯素由脂聯素單體組成,脂聯素單體連接形成三聚體,4~6個三聚體結合形成高分子結構,其中脂聯素單體只存在于脂肪細胞中,形成多聚體后才會被分泌到血漿中。
迄今為止,發現的脂聯素受體有3個,分別為脂聯素受體1、脂聯素受體2、T-鈣黏素。其中,Yamau-chi等發現了脂聯素的2個受體,分別命名為脂聯素受體1和脂聯素受體2。脂聯素受體具有7次跨膜結構域,但與G蛋白偶聯受體家族結構不同,其N端位于膜內,C端位于膜外,可與脂聯素受體結合。脂聯素受體1主要在骨骼肌細胞表達,是球形脂聯素的高親和受體及全長脂聯素的低親和受體,與腺苷激酶(AMPK)有關;而脂聯素受體2主要在肝細胞表達,是全長脂聯素和球形脂聯素的中等親和受體,能激活PPAR。T-鈣黏素主要在內皮細胞及平滑肌中表達,主要作用是與心臟、肌肉和血管等組織的脂聯素結合。Parker-Duffen等發現,T-鈣黏素敲除小鼠血液中的脂聯素水平較正常小鼠升高4倍,而心臟、血管中的T鈣黏素表達減少,經過重組脂聯素**后,T-鈣黏素在細胞表面的表達可以恢復正常水平。由于脂聯素與其受體結合后發揮了多種生物學作用,所以任何影響脂聯素受體表達的因素均將影響脂聯素生物學效應的發揮及其相關性**的發生和發展。 [1]
