NSR:乙型肝炎病毒相关性肝细胞癌的肿瘤微环境

肝细胞癌是世界上第五大常见恶性肿瘤,为癌症死亡第三大原因。与很多癌症不同,肝细胞癌的发生与慢性肝脏疾病进程密切相关。

乙型肝炎病毒感染是HCC最重要的病因之一,HBV诱发肝癌通常伴随或继发于长期的慢性肝炎、炎症反应和肝硬化。近年的研究表明,除了直接影响肝细胞癌变之外,HBV感染还通过调控肿瘤微环境来影响肝细胞癌的发生,发展和转移。



《国家科学评论》(National Science Review)2014年第三期REVIEW栏目(396~412页)

发表了美国杜克大学医学院王小凡教授的综述文章,详尽阐述了近年来发现的HBV感染相关肝细胞癌肿瘤微环境中的细胞组分、非细胞组分及其相关作用机制。



文中提到HBV感染相关肝细胞癌肿瘤微环境中的细胞成分包括肿瘤浸润性淋巴细胞、树突状细胞、巨噬细胞和库夫氏细胞、自然杀伤细胞、肿瘤相关成纤维细胞和肝脏星状细胞及内皮细胞等;非细胞组分主要有细胞因子和趋化因子,生长因子和其他可溶性蛋白,微小RNA及物理免疫微环境等。

王小凡教授同时指出,肝细胞癌形成背景复杂,肿瘤微环境还会随着肝细胞癌的发生、发展及转移等过程呈现出高度的动态变化和更为复杂的交互作用系统。

HBV感染对于肝细胞癌微环境中细胞组分及非细胞组分的调控起着关键作用,可显着影响肝细胞癌的发展和预后。阐明这一交互系统中的主要成分及作用机制,分析动态变化的肿瘤微环境的共性及不同之处,对于发展更加有效、针对性更强的治疗方法意义重大。
