    • New recombinant oncolytic viral vectors have been constructed based on a known herpes simplex virus-1 with a single 34.5 gene and a synctial mutation (called OncSyn (OS) virus), which was designed to be more immunogenic than the parental OS virus largely due to deletion of the viral gene viral host shutoff (vhs) gene (the "OSV" virus). In another embodiment, the OSV virus was constructed to constitutively express 15-PGDH (the "OSVP" virus), the principal enzyme responsible for degradation of PGE2. OSVP was shown to decrease both breast tumors and prostate cancer tumors in mice models. In addition, OSVP was shown to trigger substantial inflammatory cytokine production and promote anti-tumor immune responsiveness. These altered viruses, OSV and OSVP, can be used to treat various cancers including breast, prostate, liver, colon, and other tissues. Other exogenous genes can be added to either OSV or OSVP to improve the therapeutic response.
    • 已经基于已知的具有单个34.5基因和合成突变(称为OncSyn(OS)病毒)的单纯疱疹病毒-1构建了新的重组溶瘤病毒载体,其被设计为比亲本OS病毒更具免疫原性,主要是由于 病毒基因病毒宿主关闭(vhs)基因(“OSV”病毒)的缺失。 在另一个实施方案中,构建OSV病毒以组成型表达导致PGE2降解的主要酶的15-PGDH(“OSVP”病毒)。 OSVP显示在小鼠模型中减少乳腺肿瘤和前列腺癌肿瘤。 此外,OSVP被证明可以引发大量的炎性细胞因子产生并促进抗肿瘤免疫反应。 这些改变的病毒,OSV和OSVP可用于治疗各种癌症,包括乳腺癌,前列腺癌,肝癌,结肠癌和其他组织。 可以将其他外源基因加入到OSV或OSVP中以改善治疗反应。

    • 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。
