Fas/Fas配体系统与胰岛素抵抗和2型糖尿病(T2 DM)的发生有关。然而,可溶性Fas配体(sFasL)在2型糖尿病(T2 DM)免疫细胞功能中的作用尚未研究。本研究的目的是确定在体外sFasL对中性粒细胞活化和凋亡的影响。我们发现sFasL具有促炎作用,并诱导caspase-1、NF-κB、IL-1β和CD 18的mRNA表达。同时,sFasL诱导活性氧(ROS)的产生。caspase-1活性的激活消除了sFasL依赖的细胞凋亡,并抑制了T2 DM患者中性粒细胞中Fas的表达和caspase-3的mRNA水平。总的来说,我们的研究结果确定了一种新的促炎作用的sFasL在T2 DM中性粒细胞是依赖于半胱天冬酶活性。因此,sFasL增强T2 DM患者中性粒细胞的炎症反应,而不增加细胞凋亡,表明其在T2 DM炎症中的触发作用。
Fas/Fas ligand system was shown to be related to insulin resistance and type 2 diabetes mellitus (T2DM). However, the role of soluble Fas ligand (sFasL) in functioning of immune cells in type 2 diabetes mellitus (T2DM) has not been studied yet. The aim of the present study was to determine in vitro effects of sFasL on neutrophil activation and apoptosis. We demonstrate here that sFasL exhibited proinflammatory effect and induced mRNA levels of caspase-1, NF-κB, IL-1β and CD18 expression. At the same time, sFasL induced reactive oxygen species (ROS) production. Activation of caspase-1 activity abolished sFasL-dependent apoptosis, and suppressed Fas expression and mRNA levels of caspase-3 in neutrophils from T2DM patients. Collectively, our findings identify a novel proinflammatory role of sFasL in T2DM neutrophils that is dependent of caspase activity. Thus, sFasL enhances inflammatory response of neutrophils from T2DM patients without increasing apoptosis suggesting its triggering role in T2DM inflammation.
