This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. HCV is a blood born pathogen that infects about 3% of the human population. More than 70% of people infected with the virus eventually get chronic hepatitis which can cause cirrhosis of the liver, hepatocellular carcinoma, autoimmune diseases, and almost 30 other associations. Initially, HCV infection is asymptomatic. After 20-30 years of infection, most of patients will have symptoms (fatigue and poor appetite) of chronic liver infection with elevated levels of liver enzymes such as AST and ALT 1) Determine the 3D structure of hepatitis C virus (HCV) and its molecular components by cryo-EM using infectious blood collected during the early stages of infection prior to the development of liver injury or specific anti-HCV antibody 2) Analyze the molecular structure of the envelope proteins, E1E2, and develop a model of interaction with cellular receptors.

该子项目是利用 NIH/NCRR 资助的中心拨款提供的资源的众多研究子项目之一。子项目和研究者 (PI) 可能已从另一个 NIH 来源获得主要资金，因此可以在其他 CRISP 条目中得到体现。列出的机构是中心的机构，不一定是研究者的机构。 HCV 是一种血源性病原体，感染约 3% 的人口。超过 70% 的病毒感染者最终会患上慢性肝炎，从而导致肝硬化、肝细胞癌、自身免疫性疾病以及近 30 种其他疾病。最初，HCV 感染是无症状的。感染 20-30 年后，大多数患者会出现慢性肝脏感染症状（疲劳和食欲不振），并伴有 AST 和 ALT 等肝酶水平升高 1) 使用感染早期阶段收集的感染性血液（在肝损伤或特异性抗 HCV 抗体出现之前）通过冷冻电镜确定丙型肝炎病毒 (HCV) 的 3D 结构及其分子成分 2) 分析包膜蛋白 E1E2 的分子结构，并开发与细胞受体相互作用的模型。
