肝母细胞瘤是一种儿童肝脏恶性肿瘤。与肝癌、胆管癌等成人肝脏恶性肿瘤不同，肝母细胞瘤由肝前体细胞发展而来，其成因与乙型肝炎病毒感染和肝硬化无关。因缺乏人肝母细胞瘤发生模型，其发病机制研究尚不清晰，药物策略尚不明确。在肝母细胞瘤患者中，80%以上患者肿瘤样本显示Wnt-β-catenin和Hippo-YAP通路的过度激活【1】。研究表明，成年小鼠肝脏中共同表达激活型β-catenin和YAP1能够导致...
衰老与一系列组织功能障碍引起的疾病发病率增加密切相关【1,2】。在自然衰老过程中机体内出现的促炎症反应状态慢性进行性升高的现象，被称为 “炎性衰老” ，是导致年龄相关的免疫失衡的常见原因【3】。自然衰老过程中免疫学变化通常表现为多种免疫细胞组成的改变和免疫功能下降。最近的研究表明，相比于年轻群体，老年群体中新型冠状肺炎（COVID-19）的发病率、危重症发生率以及死亡率显著增加【4,5】。然而目前...
