Mol Cell Proteomics:癌症治疗中,影响rituximab结合的FcγR糖型鉴别

2017-06-09 Emma MedSci原创

寡糖单糖结构在每种来源的FcγRI上是普遍存在的,并且可能通过一种稳定效应促进高亲和力的rituximab相互作用。在FcγRI和FcγRIIIa上,大的和唾液酸化的聚糖可能通过不稳定的相互作用来影响与rituximab结合的稳定。

Rituximab(中文名:美罗华、利妥昔单抗)是一种广泛应用于治疗非霍奇金氏淋巴瘤和一些其它淋巴瘤、以及自身免疫性疾病的单克隆抗体类药物。FcγR结合抗体的Fc区产生抗体依赖性细胞的免疫应答,如ADCC(抗体依赖的细胞介导的细胞毒性作用),CDC(补体依赖的细胞毒性)和ADCP(抗体依赖性细胞的吞噬作用),在癌症的治疗中起非常重要的作用。免疫效应细胞活性与FcγRs的生物分子参与直接相关,其中抗体和受体的蛋白质和聚糖部分都可以相互影响互相作用,发表于Mol Cell Proteomics的一篇论文深入研究了FcγR的聚糖部分在其中的作用。

研究人员提供一份CHO(中国仓鼠卵巢)表达人FcγRI(CD64), RIIa Arg131/His131(CD32a),RIIb(CD32b)和RIIIa Phe158/Val158(CD16a)的聚糖组成的完整描述,分析其在与IgG的结合中的作用。对rituximab与每种FcγR的相互作用进行表征,并研究了CHO-FcγRIIIa Phe158/Val158和CHO-FcγRI的相互作用,并将其与人(HEK293)和鼠(NS0)产生的受体的等效相互作用进行比较。

结果显示聚体类型和丰度在受体之间显著不同,显示与rituximab相应的FcγR结合模式的明显差异,推测原因在于不同情况下宿主细胞依赖性FcγR糖基的差异。寡糖单糖结构在每种来源的FcγRI上是普遍存在的,并且可能通过一种稳定效应促进高亲和力的rituximab相互作用。在FcγRI和FcγRIIIa上,大的和唾液酸化的聚糖可能通过不稳定的相互作用来影响与rituximab结合的稳定。研究结果进一步说明,IgG1-FcγR结合动力学的不同是由于FcγR的糖基化的不同,也为"FcγR聚糖在抗体结合相互作用的稳定作用"这一课题提供进一步的参考。

Diabetes Care:晚期糖基化终末产物可预测早期DN

晚期糖基化终产物(AGEs)和氧化产物(OPs)增加可能会引起糖尿病肾病(DN)进展。针对这个问题,来自美国汉诺威马达特茅斯大学盖泽尔医学院医学/内分泌学系的Beisswenger博士等人进行了一项研究,他们对103名参与”糖尿病肾病自然病史研究”的1型糖尿病患者AGEs、OPs与DN进展的关系进行了研究。研究发现,三个主要的AGEs可能是重要的DN进展的早期预测指标。研究结果在线发表于2013年

Adv Sci:王宏达研究组揭示癌细胞表面糖基分布规律

糖类分子是细胞膜的重要组成成份,它参与了细胞多种生理活动,决定着细胞﹣细胞以及细胞﹣外界环境间的相互作用。糖基化的异常与许多疾病有着密切联系,例如肿瘤的发生、恶性转变、癌细胞的扩散和转移等。由于糖链结构的纷繁复杂、与癌症相关的糖链变化多样、癌症发生和发展过程中涉及的糖类分子种类众多,因而想要确定与癌变相关的糖类分子整体变化是极其困难的。目前,对于癌症相关糖分子的研究多集中在体外的传统方法检测分析。

Diabetes:糖基化LDL致AS作用增强

  英国学者的一项研究表明,丙酮醛(MG)修饰低密度脂蛋白(LDL)可形成小而致密的LDL,其致动脉粥样硬化(AS)作用增强。这可能对糖尿病心血管风险递增和二甲双胍的心脏保护作用做出了解释。论文于2011年5月26日在线发表于《糖尿病》(Diabetes)杂志。   研究者分离出人类LDL并且在体外通过MG最低限度修饰LDL(MGmin-LDL)。研究者对MGmin-LDL的致动脉粥样硬化特征进
