慢病毒介导强制泛素化HBcAg基因修饰小鼠髓源性树突状细胞体外诱导细胞毒性T淋巴细胞反应
发布时间:2021-08-03 12:26
乙型肝炎病毒(hepatitis B virus, HBV)的慢性感染仍然危害人类健康,全球大约有3.5亿人感染HBV,部分患者最终进展为肝硬化、肝细胞癌。目前尚无有效的方法彻底清除患者体内的乙肝病毒。特异性的细胞免疫反应在控制HBV的感染中起关键性作用,通过抗原刺激产生特异性细胞毒性T淋巴细胞(cytotoxic T lymphocytes, CTL)是清除慢性HBV感染者体内病毒的一个有效途径。泛素-蛋白酶体系统(ubiquitin-proteasome system, UPS)是一种广泛存在于真核细胞内依赖ATP的高选择性蛋白质降解体系,它由泛素(ubiquitin, Ub)、泛素活化酶(ubiquitin-activating enzyme, E1)、泛素结合酶(ubiquitin-conjugating enzyme, E2)、泛素-蛋白连接酶(ubiquitin-protein ligase, E3)、26S蛋白酶体及去泛素化酶(deubiquitinating enzyme, DUB)等组成。泛素化的蛋白被蛋白酶体复合物识别后降解为若干小肽段,可以与MHCⅠ类分子结合被抗...
