品系介绍

TNFSF11基因(亦称核因子κB受体活化因子配体,RANKL)编码肿瘤坏死因子超家族中一个关键成员,其表达广泛分布于骨微环境与免疫系统中的多种细胞类型,包括成骨细胞、骨细胞、骨髓基质细胞、活化T细胞以及部分B细胞等 [1]。该基因所编码的细胞因子通过特异性结合信号受体TNFRSF11A/RANK和诱饵受体TNFRSF11B/OPG,调控破骨细胞分化、活化与骨重塑等核心生物学过程,并参与淋巴结器官发生、T细胞与树突状细胞相互作用以及乳腺发育等 [2]。TNFSF11在骨稳态与适应性免疫中发挥核心作用:一方面作为破骨细胞分化与活化的关键诱导因子,介导骨吸收与钙磷代谢调节 [3];另一方面为免疫细胞提供存活与功能信号,并在炎症条件下促进骨-免疫交互 [4]。TNFSF11的表达或信号失调已被证实与多种疾病存在病因学关联。功能缺失突变导致破骨细胞生成障碍,从而引起常染色体隐性骨硬化症(osteopetrosis);而信号过度活化或表达异常则促进病理性骨吸收,参与骨质疏松、类风湿关节炎(RA)骨侵蚀以及乳腺癌、前列腺癌等肿瘤骨转移的发生 [5-8]。
huRANKL(TNFSF11)小鼠是通过基因编辑技术构建的人源化模型,将小鼠内源性Tnfsf11基因编码胞外域的序列替换为人源TNFSF11基因编码胞外域的序列。该模型可用于骨质疏松症、类风湿关节炎骨侵蚀、骨硬化症和肿瘤骨转移等多种骨代谢与骨免疫相关疾病的机制研究,及TNFSF11靶向抗体、小分子抑制剂等药物的筛选、研发及临床前体内评价。
