    • The invention relates to engineered Herpes simplex virus (HSV) particles exhibiting a binding pair member that specifically binds to, or targets, one or more specific binding partners, such as receptors, including binding partners lacking at least one of a cytoplasmic domain or a transmembrane domain. Also, recombinant vectors for producing such HSV particles are provided. By reducing the affinity of HSV for its natural receptor(s) and increasing the affinity for a selected receptor, the HSV particles of the invention are useful for targeting cells that express the selected, receptor, which itself may be a product of genetic engineering. The ability to selectively target cells renders the HSV particles particularly useful in selectively diagnosing, treating, and imaging cells bearing the selected binding pair member, such as a receptor. The invention also provides for polynucleotide-based therapy to cells bearing the selected binding pair member such as a receptor.
    • 本发明涉及工程化的单纯疱疹病毒(HSV)颗粒,其显示结合对成员,其特异性结合或靶向一种或多种特异性结合配偶体,如受体,包括缺乏胞质结构域或跨膜结构中的至少一种的结合配偶体 域。 而且,提供了用于生产这种HSV颗粒的重组载体。 通过降低HSV对其天然受体的亲和力并增加对所选受体的亲和力,本发明的HSV颗粒可用于靶向表达选择的受体的细胞,所述受体本身可以是基因工程的产物。 选择性靶向细胞的能力使得HSV颗粒特别适用于选择性诊断,治疗和成像携带选择的结合对成员的细胞,例如受体。 本发明还提供了对携带选择的结合对成员如受体的细胞进行基于多核苷酸的疗法。
