Stroke:波形蛋白和脑卒中的发生率正相关

波形蛋白和脑卒中的发生率正相关


VIM(vimentin)波性蛋白是一种细胞骨架中间丝蛋白,在细胞内动力学和结构中起重要作用。它表达在不同细胞类型的表面,并由内皮细胞、活化的巨噬细胞和星形胶质细胞分泌到细胞外环境中。VIM参与了广泛的细胞功能,包括分化、粘附、迁移、信号转导和细胞凋亡。因此,它在癌症的发展和转移中受到了很多科学关注,并且也与许多其他病理生理条件有关,如白内障、克罗恩病和类风湿性关节炎


最近的研究表明,VIM与动脉粥样硬化的发展有关。一项对冠状动脉疾病患者和健康对照组的研究报道,冠状动脉疾病患者血清中VIM水平较高,且VIM水平与病变冠状动脉的数量呈正相关。

此外,有研究表明,在载脂蛋白E-/-小鼠腹腔注射重组VIM可诱导主动脉组织中的动脉粥样硬化和促炎症表达,也有报道称VIM的各种促炎症作用。例如,VIM结合12/15-脂氧合酶的启动子并调节其活性,进而诱导内皮炎症。VIM还可以诱导巨噬细胞分泌促炎细胞因子,从而可能促进动脉炎症。

尽管VIM和动脉粥样硬化之间有几种可能的联系,而动脉粥样硬化是中风的主要原因之一,但VIM是否与中风的发生率有关尚不清楚。

瑞典隆德大学的Jun Xiao等人,基于Malm. Diet and Cancer Cohort队列,探究了VIM与中风发病率增加的关系。

他们的前瞻性研究数据来自1991年至1994年期间,从4688名参与者(39.7%为男性;平均年龄57.6岁)采集数据,并采集了血液样本。中风的发生率被跟踪至2018年。通过使用Cox回归评估VIM和卒中之间的关系。

结果显示:
在平均22.0年的随访中,共有528名受试者被诊断为卒中,其中434人是缺血性卒中。在调整潜在混杂因素后,最高四分位数(vs第一四分位数)的参与者总卒中风险高1.34倍(95% CI,1.03-1.74),缺血性卒中风险高1.47倍(95% CI,1.10-1.98)。

颈动脉斑块和VIM对总卒中和缺血性卒中的发生率均有显著的相互作用(分别为P=0.041和0.011)。

按颈动脉斑块分层后,有颈动脉斑块的参与者中,高VIM与卒中的关联性更强,尤其是缺血性卒中的风险(调整后的危险比,1.66)。

这个研究的重要意义在于,发现了VIM与卒中的发生率呈正相关,尤其是在有颈动脉斑块的个体中,可能需要更多类似的研究去证实证实他们观察到的结论。
