乙型肝炎病毒 病毒性疾病 蛋白酶 核传感器
2022/9/15
新发和反复爆发的病毒性疾病是一个严重的公共卫生问题。历史上,乙型肝炎病毒 (HBV) 已夺去数百万人的生命。目前,COVID-19大流行已造成巨大的经济损失和数百万人死亡。乙型肝炎是一种慢性病毒性疾病,其主要挑战是消除HBV共价闭合环状DNA (cccDNA),减少乙型肝炎表面抗原 (HBsAg)。
2021年6月29日,北京生命科学研究所/清华大学生物医学交叉研究院李文辉实验室在《Cell Reports》杂志发表题为“Transcriptionally Inactive Hepatitis B Virus Episome DNA Preferentially Resides in the Vicinity of Chromosome 19 In 3D Host Genome Upon In...
2021年3月2日,中科院生物物理所杨鹏远课题组与王凡课题组合作在《Cancer Research》杂志发表题为"Hepatitis B-induced IL-8 Promotes Hepatocellular Carcinoma Venous Metastasis and Intrahepatic Treg Accumulation"的研究论文,阐述了乙型肝炎病毒(HBV)感染中HBx诱导趋化细...
乙型肝炎病毒(human hepatitis B virus,HBV)是引起人类乙型肝炎的病原体,能引起急慢性肝炎、肝硬化、肝癌等多种临床疾病,是我国最常见的病毒性肝炎。虽然目前有HBV疫苗,但对慢性HBV感染仍无有效治疗手段。HBV感染仍然是世界性的严重公共卫生问题。缺乏合适的HBV感染动物模型是研究发病机制和研发药物及疫苗的瓶颈。树鼩是灵长类动物亲缘关系较近的新型实验动物,有研究发现HBV可感...

Estimation of Parameter Uncertainty in the HBV Model
Estimation of Parameter Uncertainty HBV Model
2009/10/23
Usually the HBV model is calibrated by seeking one optimal parameter set that
represents the catchment. From experience we know, however, that it is hardly
poss~ble to find an unique parameter set. ...
