CD24 & Siglec-10蛋白 – 肿瘤免疫治疗热门靶点

背景
癌细胞表面表达特定的“别吃我”的信号分子(如CD24、CD47、PD-L1、B2M)后会被免疫细胞识别为正常细胞,从而逃避肿瘤微环境中巨噬细胞的吞噬清除。最早发现的“别吃我”信号蛋白是PD-1和CTLA-4,2019年7月发表在Nature的一项研究表明CD24是卵巢癌和三阴乳腺癌细胞表达的另一个“别吃我”信号蛋白,被癌细胞用来保护自己,CD24是开发癌症免疫疗法潜在靶点。
CD24(Cluster of Differentiation 24)是一种高度糖基化的糖基磷脂酰肌醇锚定的细胞表面蛋白。卵巢癌和三阴乳腺癌细胞表面上表达的CD24蛋白可以与免疫细胞上的Siglec-10蛋白相互作用来传递免疫抑制性信号,从而抑制破坏性炎症反应。
目前,市面的CD24蛋白大多都只有与抗体结合的数据,缺少与Siglec-10蛋白结合活性的验证,而CD24抗体药研发的关键点在于其能够有效地阻断CD24与Siglec-10的结合。为了解决这些问题,ACROBiosystems开发了不同标签的CD24蛋白以及CD24过表达细胞株,并验证了细胞株与Siglec-10的结合活性。另外还验证了抗CD24中和抗体SN3可以有效的阻断Siglec-10与CD24过表达细胞株的结合。
