Nat Commun:研究发现LL-37/CRAMP是血小板活化和血栓炎症的重要介质

2018-05-02 MedSci MedSci原创

白细胞释放的抗菌肽有助于消除病原体和激活免疫系统,但是其在血栓形成中的作用尚未完全了解。在这里我们显示cathelicidin LL-37在急性心肌梗塞患者的血栓中的水平较高。其小鼠同系物CRAMP存在于血管损伤后的小鼠动脉血栓中,并且主要来源于循环中性粒细胞。骨髓嵌合体小鼠中造血CRAMP的缺乏减少了血小板募集和血栓形成。LL-37和CRAMP通过蛋白酪氨酸激酶Src/Syk和磷脂酶C参与糖蛋白

白细胞释放的抗菌肽有助于消除病原体和激活免疫系统,但是其在血栓形成中的作用尚未完全了解。

在这里我们显示cathelicidin LL-37在急性心肌梗塞患者的血栓中的水平较高。其小鼠同系物CRAMP存在于血管损伤后的小鼠动脉血栓中,并且主要来源于循环中性粒细胞。骨髓嵌合体小鼠中造血CRAMP的缺乏减少了血小板募集和血栓形成。

LL-37和CRAMP通过蛋白酪氨酸激酶Src/Syk和磷脂酶C参与糖蛋白VI受体和下游信号传导,从而在体外诱导血小板活化。除了急性血栓形成之外,LL-37/CRAMP依赖性血小板活化通过调节嗜中性粒细胞的募集和外渗到组织中来促进血小板-中性粒细胞在其他炎症条件下的相互作用。

缺乏CRAMP可以消除酸性肺损伤,这是一种依赖于血小板-中性粒细胞相互作用的小鼠肺炎模型。我们建议LL-37/CRAMP代表血小板活化和血栓炎症的重要介质。

阳离子抗菌肽(CAPs)和模拟CAPs的双亲结构的合成分子,如ceragenins,是开发新型抗菌药物的有前景的化合物。研究人员测试了ceragenins CSA-13和CSA-131在体外对几种厌氧细菌(包括拟杆菌属和艰难梭菌)的抗菌作用。将CSA-13和CSA-131连接到磁性纳米颗粒(MNPs)制备导管素LL-37,与甲硝唑和纳米系统的活性进行了比较。使用杀伤试验和改良的CLSI肉汤微量稀释

J Med Chem:天然抗菌肽的选择性免疫激活功能和败血症预防效应

传统抗生素的大量使用和滥用导致临床上出现了各种各样的耐药菌株,成为危害人类健康的重大威胁。在与致病菌变异竞争的过程中,自然界各种来源的抗菌肽目前成为人们研发新型抗感染药物的新希望,但目前人们对抗菌肽的认识和研究仍主要集中于其直接杀灭细菌生长的效应上。 败血症是主要由细菌感染引起的伴随有全身性炎症反应综合症状的一种危重疾病,病原微生物感染诱导促炎症因子大量释放,导致多种重要器官衰竭具有非常高的死亡

Science:肠道中的有益微生物如何抵抗炎症

据一项由T.W. Cullen和同事所做的新的研究披露,我们体内有许多有益的肠道微生物能通过一种简单切换至其保护性外披层而在炎症中存活下来。 当像沙门氏菌等有害微生物感染肠道时,我们的身体会释放出强力的抗微生物肽来击退入侵者。但这些病原微生物看上去常常类似于生活在肠道内的共生性“有益”微生物,因此研究人员常常想知道这些共生菌是否能挺住由这些肽所产生的炎症。 Cullen和

Science:新生脂肪可帮助对抗细菌感染

在一个崇尚“纤瘦美”的社会里,任何与“脂肪”有关的物质仿佛都成了不好的东西。许多人提起自己体内存在的大量脂肪就深感恐惧,更别提“臭名昭著”的胆固醇了。实际上,身体内的各种物质各司其职,即使被很多人厌恶的脂肪,也在人体的正常运作中扮演着重要作用。脂肪层能够保护脏器,维持体温,乃至在免疫过程中发挥重要作用。发表在最新一期《科学》杂志上的研究成果指出,分化中的皮下脂肪组织能够分泌一种抗菌肽并杀死金黄色葡
