CD39/CD73:肿瘤免疫腺苷酸通路明星靶点

背景
肿瘤微环境(TME)是肿瘤免疫治疗的重要影响因素之一,ATP/ ADO(腺苷/adenosine)通路是肿瘤微环境调控的主要通路,而CD39/CD73在ATP/ ADO(腺苷/adenosine)通路中至关重要,在先天性和适应性免疫中发挥着重要作用。
其中CD39是一种跨膜三磷酸腺苷二磷酸水解酶-1(Ectonucleoside triphosphate diphosphohydrolase-1,ENTPD1),具有两个跨膜结构域和一个胞外结构域,其活性中心在胞外结构域上,两个跨膜结构域之间的互相作用也可能影响其酶活性。CD39在多种免疫细胞(NK细胞、CD4+ 、CD25+ 、调节性T细胞 (Treg)、巨噬细胞等),非免疫细胞( 内皮细胞和成纤维细胞)以及肿瘤细胞中( 淋巴瘤、肉瘤、肺癌等)中均有表达,由此奠定其在肿瘤免疫中的基础作用。
CD73是一种胞外-5′-核苷酸酶(NT5E),以同源二聚体形式存在于细胞表面,也可以游离形式存在于胞外。CD73主要由3个结构域组成,N端结构域,包含2个锌离子结合位点,C端结构域含底物结合位点, N端和C端结构域之间的短螺旋可控制酶的运动。其广泛表达于人体多种组织细胞表面,包括淋巴细胞、内皮细胞和上皮细胞,控制多种生理活动。
在其功能上,CD39能与胞外ATP(eATP)结合,并将其水解为AMP; CD73则会将AMP水解为ADO。在ATP-ADO通路中,CD39是eATP水解的限速酶,而CD73是AMP水解的限速酶。通过CD39CD73来控制嘌呤核苷酸的生成,进而调控核苷酸的信号传递。CD39可将能有效激活免疫细胞活性的eATP水解进而造成肿瘤的免疫逃逸;而CD73水解产生的ADO可活化免疫细胞,降低T细胞的免疫作用,进而导致肿瘤免疫逃逸。
因此,以CD39/CD73为靶点的大小分子药物的研发,成为调控肿瘤微环境ATP/ ADO(腺苷/adenosine)通路的新思路,进而为肿瘤免疫治疗提供新方向。 为加速CD39/CD73药物研发,ACROBiosystems提供CD39CD73系列产品,纯度和生物活性经过验证并且可以免费提供活性验证Protocol,可应用于免疫、抗体筛选等应用场景,加速CD39/CD73药物研发。

  3. 购买蛋白用于测试CD39封闭性抗体封闭CD39水解ATP的功能实验。通过系列梯度CD39抗体与一定浓度的CD39(0.5ug/ml)孵育,再加入50uM ATP,用CTG检测,得到很好的曲线。证明该蛋白具有很好的ATP酶水解功能。

  3. It was used in research of investgational new drugs. Specifically, I have used this product in my Epitope binning experiments (using Octet) and I am truely satisfied with the results. With this experiment and your product, we have found a approximate epitope binding site. Thanks for your highly qualified product.
