    • The present disclosure provides compositions and methods useful for treating HCV infection. As described herein, the compositions and methods are based on development of immunogenic compositions that include virus-like particles (VLPs) which comprise one or more Moloney Murine leukemia virus (MMLV) core proteins and include one or more HCV epitopes, such as, for example, from HCV envelope glycoprotein El and/or E2 or variants thereof (e.g., E2G) and/or non-structural proteins NS3 and/or NS4A. Among other things, the present invention encompasses the recognition that a combination of antigens (e.g., envelope glycoproteins and interior non-structural proteins) can lead to beneficial immune responses, for example that include both a humoral response (e.g., production of neutralizing antibodies) and a cellular response (e.g., T-cell activation).
    • 本公开提供了可用于治疗HCV感染的组合物和方法。 如本文所述,组合物和方法基于免疫原性组合物的开发,所述免疫原性组合物包括包含一种或多种莫洛尼鼠白血病病毒(MMLV)核心蛋白的病毒样颗粒(VLP),并且包括一个或多个HCV表位,例如 例如,来自HCV包膜糖蛋白E1和/或E2或其变体(例如E2G)和/或非结构蛋白NS3和/或NS4A。 除其他之外,本发明包括认识到抗原(例如,包膜糖蛋白和内部非结构蛋白)的组合可导致有益的免疫应答,例如包括体液应答(例如产生中和抗体) 和细胞反应(例如T细胞活化)。
