领域奠基之作：Cell 重磅报道可胞外展示的糖基化修饰 RNA——glycoRNA
glycoRNA，但三种凝集素 rRNA 条带都很弱。因此，在活细胞实验中的结果再次表明，大多数细胞 glycoRNA 位于细胞表面。 图片来源：Cell Siglec 受体和抗 RNA 抗体可以识别细胞表面的 glycoRNA 由于 glycoRNA 位于细胞表面，研究人员想进一步评估现有的研究细胞表面生物学的试剂（抗体或重组蛋白亲和剂）是否与 glycoRNA 相互作用。J2 抗双链 RNA 抗体对 RNA 的 ds 区有特异性，通常用来识别感染 RNA 的细胞。在证实
Cell：「来骗来偷袭」剪接体靶向疗法「诱骗」机体，激活抗病毒免疫，让肿瘤自杀
。作者使用 dsRNA 特异性抗体（J2 抗体）对多个 TNBC 系进行免疫荧光染色发现 H3B-8800 诱导了细胞质 dsRNA 显著增加。dsRNA 特异性 RNase III 处理消除了 J2 信号，表明 J2 抗体特异性识别 dsRNA 结构的积累。接下来作者进一步证实剪接体的直接扰动诱导 dsRNA 积累。 在内源性剪接因子 SF3B1 基因敲除背景下，外源 SF3B1-FKBP12F36V 降解导致细胞质 dsRNA 的积累，与 H3B-8800 作用一致。 作者进一步证实 H
