IGLH:血小板阻抗测定法:一种测量血小板粘附和扩散的新技术

2018-05-30 MedSci MedSci原创

现如今,血栓形成对发病率和死亡率起着重要的作用。抗血栓药物是最常见的处方药之一。需要彻底了解血小板功能,才能获得最佳的临床护理。血小板粘附是血小板血栓形成过程的独立进程。尽管如此,目前还没有一种标准的方法可以用来来测量血小板粘附。阻抗测定是一种用于分析细胞粘附、增殖、存活和细胞毒性最可靠、最先进的技术。我们提出了一种可行的新方法,用于分离测量2个重要的血小板功能-----粘附和扩散。 研究人

现如今,血栓形成对发病率和死亡率起着重要的作用。抗血栓药物是最常见的处方药之一。需要彻底了解血小板功能,才能获得最佳的临床护理。血小板粘附是血小板血栓形成过程的独立进程。尽管如此,目前还没有一种标准的方法可以用来来测量血小板粘附。阻抗测定是一种用于分析细胞粘附、增殖、存活和细胞毒性最可靠、最先进的技术。我们提出了一种可行的新方法,用于分离测量2个重要的血小板功能-----粘附和扩散。

研究人员应用xCELLigence SP系统对血小板功能进行分析,采用实验室参考血小板凝固剂(肾上腺素、ADP、胶原蛋白)来描述血小板功能。从20例健康并无药物治疗的患者中获得血小板样本,并对标准实验室参数和临床病史进行了分析。

在浓度依赖的情况下,肾上腺素和ADP可增加血小板粘附,而胶原蛋白倾向于产生负面影响。血清钠、钙的水平和年龄与肾上腺素和ADP诱导的血小板粘附呈负相关,而与过敏性疾病相关的免疫反应增加与肾上腺素和ADP诱导的血小板粘附增加有关。ADP可以浓度依赖性的方式增加血小板。

在对血小板粘连的定性和定量测量中,阻抗测定被证明是一种有用且敏感的方法,甚至可以区分健康人群的亚群。该新技术是进一步研究血小板功能的一种重要方法。

中心点:首次定量分析动态血小板脂质调节,揭示血小板活化的关键脂质变化。SMPD1可通过调节lyso-sphingomyelin调控血小板脂质和激活。摘要:血小板的完整性和功能显著依赖于脂质成分。但是,迄今为止,血小板的脂质含量仍无定量数据。对此,Bing Peng等人在一个定量的血脂平台上通过脂类特定性协议检测小鼠血小板的脂质。结果显示血小板脂质体包含近400种脂质种类,浓度范围覆盖7个数量级。对

Mol Ther:上海药物所发现整合素aIIbβ3的种属差异与单抗诱导的血小板减少症相关

在目前世界范围内,治疗性单克隆抗体(Monoclonal antibodies,mAbs)销售额已达数百亿美元,占到整个生物制药市场份额的三成以上。虽然大部分mAbs在人体中能够良好地耐受,但也依然会造成包括免疫反应、感染性疾病、自身免疫疾病、血小板减少、血栓形成障碍、皮炎及心血管毒性等毒副作用。因此,如何在药物研发前期尽早地发现mAbs造成的不良反应显得极为重要。

J Viral Hepat:采用常规临床指标预测慢性乙肝患者肝脏炎症程度

GPR可以作为一种新的、简单的指标来预测CHB患者的肝脏炎症,尤其是HBeAg阳性CHB。

Blood:灭活血小板的病原体是否影响其止血效果?

中心点:仅在意向治疗分析中,病原体灭活性血小板的止血效果上为非劣效性。与动脉模型相比,应用病原体灭活性血小板时不能预防同种异体免疫。摘要:病原体失活的浓缩血小板可降低血源性感染的风险。但灭活病原体对血小板功能和输血的止血作用的影响尚不明确。近日Blood杂志上发表一篇相关文章,Pieter F. van der Meer等人进行一随机的非劣效性试验,对比用核黄素和紫外B光照技术病原体灭活血小板(干

EuroPCR 2018丨抗血小板界的“多面手”,你认识吗?

新研究丰富了替格瑞洛的多效性:替格瑞洛除抗血小板作用之外,还可带来额外获益。

Blood:GPIbα对血小板介导的肝TPO合成至关重要!

中心点:血小板GPIbα可诱导肝促血小板生成素(TPO)合成、维持TPO血液浓度。抗胞外GPIbα抗体可减少TPO合成,在免疫介导的血小板减少症中影响TPO水平。摘要:促血小板生成素(TPO),一种主要由肝脏合成的造血生长因子,对血栓形成至关重要。当前主流理论认为循环TPO水平是通过被血小板和巨核细胞的表面c-Mpl受体内化作用清除来维持的。近期,Miao Xu等人意外的发现与野生型(WT)小鼠相
