    • The present invention pertains to methods for preventing reovirus recognition in the treatment of cellular proliferative disorders, and particularly ras-mediated cellular proliferative disorders, in mammals. The mammal may be selected from dogs, cats, sheep, goats, cattle, horses, pigs, mice, humans and non-human primates. The method comprises suppressing or otherwise inhibiting the immune system of the mammal and, concurrently or subsequently, administering to the proliferating cells an effective amount of one or more reoviruses under conditions which result in substantial lysis of the proliferating cells. In particular, the methods provide for reovirus treatment of immunosuppressed or immuno-deficient mammals to treat the proliferative disorders. Immunosuppression,immunoinhibition or otherwise inducing an immunodeficient state in a mammal renders the reovirus more effective. The methods may include the selective removal of immune constituents that may interfere with the systemic delivery of the virus; preventing reovirus recognition by the host immune system; and removal of the virus from an immune suppressed or immune incompetent host following treatment with reovirus. Alternatively, reovirus may be administered to a mammal with a diminished immune response system under conditions which result in substantial lysis of the proliferating cells. Immune systems may be compromised by one or more of the following: an HIV infection; as a side effect of chemotherapy or radiation therapy; by selective removal of B and/or T cell populations; by removal of antibodies (anti-antireovirus antibodies or all antibodies), and the like.
    • 本发明涉及在哺乳动物中治疗细胞增殖性病症,特别是ras介导的细胞增殖性病症中预防呼肠孤病毒识别的方法。 哺乳动物可以选自狗,猫,绵羊,山羊,牛,马,猪,小鼠,人类和非人灵长类动物。 该方法包括抑制或以其他方式抑制哺乳动物的免疫系统,同时或随后在导致增殖细胞基本裂解的条件下向增殖细胞施用有效量的一种或多种呼肠孤病毒。 具体而言,所述方法提供免疫抑制或免疫缺陷哺乳动物的呼肠孤病毒治疗以治疗增殖性疾病。 免疫抑制,免疫抑制或以其他方式诱导哺乳动物的免疫缺陷状态使得呼肠孤病毒更有效。 该方法可以包括选择性去除可能干扰病毒全身递送的免疫成分; 防止宿主免疫系统识别呼肠孤病毒; 并在用呼肠孤病毒治疗后从免疫抑制或免疫不全宿主中除去病毒。 或者,可以在导致增殖细胞大量裂解的条件下将呼肠弧病毒给予具有减少的免疫应答系统的哺乳动物。 免疫系统可能受到以下一种或多种危害:HIV感染; 作为化疗或放疗的副作用; 通过选择性去除B和/或T细胞群体; 通过除去抗体(抗抗病毒抗体或全部抗体)等。

    • The present invention is directed to a method of producing recombinant viral vectors at high titers incorporating a variety of important advancements over the art. The method of the present invention incorporates multiple features which provide enhanced production of viruses, particularly those viruses encoding exogenous transgenes. The specifically illustrated method describes a method for the high titer serum-free media production of recombinant replication defective adenoviruses containing an exogenous transgene. The invention provides methods of preparing microcarriers, methods for seeding bioreactors at high cell density, increasing the infectivity of the producer cells to the virus, methods to increase product yield through synchronization of the cell cycle of the producer cells, and methods to minimize the deleterious effects of exogenous transgenes. The invention further provides producer cells prepared by the process of the invention. The invention further provides viruses produced by the process.
