1型糖尿病(T1 D)是由胰腺β细胞的进行性免疫细胞介导的破坏引起的。随着免疫细胞迁移到胰岛中,它们穿过细胞外基质(ECM)。该ECM由定位于胰岛内和周围的不同隔室的不同大分子组成;然而,该ECM参与人类T1 D的发展尚不清楚。在这里,我们总结了我们最近从人类和小鼠研究中的发现,说明了构成胰岛基底膜和间质基质的胰岛ECM的特定成分,以及令人惊讶的是,胰岛β细胞本身的细胞内组成在T1 D的发病过程中是如何显著改变的。我们的重点是ECM分子层粘连蛋白,胶原蛋白,硫酸乙酰肝素/硫酸乙酰肝素蛋白聚糖,和透明质酸,以及降解这些ECM成分的酶。我们认为,胰岛和淋巴组织ECM的组成和组织是至关重要的,以促进免疫细胞活化,胰岛侵入和破坏胰岛β细胞在T1 D。
Type 1 diabetes (T1D) results from progressive immune cell-mediated destruction of pancreatic β cells. As immune cells migrate into the islets they pass through the extracellular matrix (ECM). This ECM is composed of different macromolecules localized to different compartments within and surrounding islets; however, the involvement of this ECM in the development of human T1D is not well understood. Here we summarize our recent findings from human and mouse studies illustrating how specific components of the islet ECM that constitute basement membranes and interstitial matrix of the islets, and surprisingly, the intracellular composition of islet beta (β) cells themselves, are significantly altered during the pathogenesis of T1D. Our focus is on the ECM molecules laminins, collagens, heparan sulfate/heparan sulfate proteoglycans, and hyaluronan, as well as on the enzymes that degrade these ECM components. We propose that islet and lymphoid tissue ECM composition and organization are critical to promoting immune cell activation, islet invasion and destruction of islet β cells in T1D.
