[Abstract]  TGFβ is a potent cytokine modulating various processes including proliferation, differentiation, ECM synthesis and apoptosis (Siegel and Massague, 2003). Thus in many tissues availability of TGFβ is tightly regulated. TGFβ is secreted as an inactive complex where it is encapsulated by the latency associated protein (LAP), a ligand trap protein, which inhibits TGFβ binding to its receptor and retains TGFβ in the extracellular matrix (ten Dijke and Arthur, 2007). TGFβ can be released from the matrix and converted into its biological active form by huge number of processes including heat, high ... [摘要]  TGFβ是调节各种过程包括增殖,分化,ECM合成和凋亡的有效细胞因子(Siegel和Massague,2003)。因此,在许多组织中,TGFβ的可用性受到严格调控。 TGFβ作为无活性复合物分泌,其中其被潜伏相关蛋白(LAP)封闭,LAP是一种配体捕获蛋白,其抑制TGFβ与其受体结合并在细胞外基质中保留TGFβ(十Dijke和Arthur,2007)。 TGFβ可以从基质中释放并通过大量的过程包括热,高和低pH,活性氧(ROS)或各种蛋白酶(例如,纤溶酶,弹性蛋白酶)的释放而转化为其生物活性形式,基质金属蛋白酶-2和-9)(Barcellos-Hoff和Dix,1996; Lyons等人,1988; Taipale等人,1994; Yu和Stamenkovic, 2000)。然而,在生理条件下,αv-类整联蛋白与LAP蛋白中的RGD三肽基序的相互作用代表了体内TGFβ释放的关键因素。具有整联蛋白结合缺陷型LAP蛋白(RGD基序突变为RGE)的小鼠重现了TGFβ1缺失的所有主要表型,进一步强调了整合素介导的TGFβ释放对体内发育和体内平衡的相关性小鼠,包括多器官炎症和血管发生中的缺陷(Shull等人,1992; Yang等人,2007)。这种引人注目的表型与TGFβ缺陷小鼠重叠,缺少αv-类整联蛋白的小鼠的表型(Aluwihare等人,2009; ...
