肝细胞癌的免疫治疗（上）

传染病网络动态 2007年第1期 16-17页

作者： Tim f.greten Michael P.Manns firouzeh Korangy 姚勤伟（编译）杨月（审校）

肝细胞癌（HCC）是世界第五大常见肿瘤，5年生存率低于5％，每年至少100万新发病例。其中一小部分病人可能适合外科切除或者局部消融治疗。但是，这些治疗受到肿瘤大小、肝脏储备功能和肝内转移的限制。因此，对于绝大多数晚期HCC患者... 详细信息

肝细胞癌（HCC）是世界第五大常见肿瘤，5年生存率低于5％，每年至少100万新发病例。其中一小部分病人可能适合外科切除或者局部消融治疗。但是，这些治疗受到肿瘤大小、肝脏储备功能和肝内转移的限制。因此，对于绝大多数晚期HCC患者来说，这些有望治愈的治疗手段都是不可能的。肝动脉化疗栓塞术（TACE）延长了已无条件行外科手术切除、肝移植或肿瘤消融治疗的患者的生存期，但是只有那些肝功能适当的患者才能够进行此项治疗。因为HCC患者基本上都有肝硬化基础，全身化疗耐受性较差，并且效果不佳。因此，根据全球性的指南（EASL或AASLD），像免疫治疗一类的备选方案最近正在晚期HCC患者中进行评估。

5．肿瘤逃逸机制肿瘤从免疫系统产生了很多逃逸机制来抑制抗肿瘤反应。产生免疫抑制因子、增加调节性T细胞、下调肿瘤抗原和MHC分子都是肿瘤细胞用以逃避免疫识别的机制。已有很清楚的证据显示发生HCC能导致肿瘤特异性免疫反应受到抑制。尤其是我们已经证实尽管在超过50％的HCC患者中检测到肿瘤特异性的细胞和体液免疫反应，但是HCC仍然有所进展。虽然有抗原特异性T细胞的出现但HCC肿瘤仍然进展，这增加了对免疫治疗该肿瘤的有效性的关注。因为下面会展示，HCC的发展导致一系列不同的免疫机制，结果就是HCC患者中肿瘤特异性免疫反应的抑制。

Neural Regeneration Research 2024年第3期19卷 469-470页

作者： Ephraim f.Trakhtenberg Department of Neuroscience University of Connecticut School of MedicineFarmingtonCTUSA

Studies from nearly 3 decades ago suggested that,in the central nervous system(CNS),myelination of axons by oligodendrocytes not only helps improve axonal conductivity but also stabilizes circuitry(Colello and Schwab,1994).Over the years,myelin sheaths produced by oligodendrocytes have been found to contain multiple molecules that are inhibitory to axonal growth(e.g.,MAG,NogoA,OMgp,Semaphorins)(Yiu and He,2006;Silver et al.,2014).After white matter injury in the adult CNS,myelin debris from damaged axons and dead oligodendrocytes accumulates in the forming glial scar and exposes these myelin-associated axon growth-inhibitory molecules to the injured axonal stumps,thereby contributing to the inhibition of axonal *** development,CNS axons reach their postsynaptic targets and stop growing before oligodendrocytes appear and myelinate them(foran and Peterson,1992;Dangata et al.,1996).Therefore,myelin-associated axon growth-inhibitory molecules interacting with already grown axons during myelination were thought to block axons from promiscuous sprouting and miswiring,thereby stabilizing neural circuitry in the CNS(Colello and Schwab,1994).
