    Abstract: Modified capsid proteins containing at least a portion of hepatitis E virus (HEV) open reading frame 2 (ORF2) having one or more cysteine residues in a surface variable loop or the C-terminus of HEV ORF2, or a portion thereof, are provided. The modified capsid proteins can be used to form hepatitis E virus (HEV) virus like particles (VLPs) having cysteine functional groups exposed on the outer-surface. The exposed cysteine functional groups can be modified via their thiol reactive group. For example, a bioactive agent, such as a cell-targeting ligand, can be conjugated to the one or more cysteines for targeted delivery of chemically activated nanocapsids.

    Abstract translation: 提供了在表面可变环或HEV ORF2的C末端或其一部分中含有至少一部分具有一个或多个半胱氨酸残基的戊型肝炎病毒(HEV)开放阅读框2(ORF2)的修饰衣壳蛋白。 修饰的衣壳蛋白可用于形成外露表面具有半胱氨酸官能团的戊型肝炎病毒(HEV)病毒样颗粒(VLP)。 暴露的半胱氨酸官能团可以通过它们的硫醇反应性基团进行修饰。 例如,生物活性剂,例如细胞靶向配体,可以与一个或多个半胱氨酸缀合,以靶向递送化学活化的纳米帽。
