慢病毒介導強制泛素化HBcAg基因修飾小鼠髓源性樹突狀細胞體外誘導細胞毒性T淋巴細胞反應
發(fā)布時間: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類健康,全球大約有3.5億人感染HBV,部分患者最終進展為肝硬化、肝細胞癌。目前尚無有效的方法徹底清除患者體內(nèi)的乙肝病毒。特異性的細胞免疫反應在控制HBV的感染中起關(guān)鍵性作用,通過抗原刺激產(chǎn)生特異性細胞毒性T淋巴細胞(cytotoxic T lymphocytes, CTL)是清除慢性HBV感染者體內(nèi)病毒的一個有效途徑。泛素-蛋白酶體系統(tǒng)(ubiquitin-proteasome system, UPS)是一種廣泛存在于真核細胞內(nèi)依賴ATP的高選擇性蛋白質(zhì)降解體系,它由泛素(ubiquitin, Ub)、泛素活化酶(ubiquitin-activating enzyme, E1)、泛素結(jié)合酶(ubiquitin-conjugating enzyme, E2)、泛素-蛋白連接酶(ubiquitin-protein ligase, E3)、26S蛋白酶體及去泛素化酶(deubiquitinating enzyme, DUB)等組成。泛素化的蛋白被蛋白酶體復合物識別后降解為若干小肽段,可以與MHCⅠ類分子結(jié)合被抗...
