迄今为止,已从脂肪组织分离出adipsin、lepfin、resitin等20余种生物活性物质,包括细胞因子、生长因子、酶、激素、补体因子、基质蛋白等多种类型,统称为脂肪因子或脂肪细胞因子[1]。在众多功能各异的脂肪细胞因子中,脂联素(APN)是至今发现的唯一一种当脂肪组织容积变大时其血 So far, more than 20 kinds of bioactive substances such as adipsin, lepfin and resitin have been isolated from adipose tissue, including cytokines, growth factors, enzymes, hormones, complement factors and matrix proteins. They are collectively referred to as adipokines or adipocytes Factor [1]. Of the many different adipocyte factors, adiponectin (APN) is the only one found so far, whose blood volume increases when its volume increases
