    摘要: Method for generating in a patient a cellular immune response to a target protein or portion thereof comprising the step of introducing into cells of the patient a vector containing a nucleotide sequence encoding a chimeric immunogen comprising a protein processing signal and the target protein or portion thereof, so that the chimeric immunogen is made within the cells and subsequently processed such that the target protein or portion thereof is presented to the patient's immune system so as to generate a cellular immune response.

    摘要: A method for producing viral gene delivery vehicles which can be transferred to pre-selected cell types by using targeting conjugates. The gene delivery vehicles comprise: 1) the gene of interest; and 2) a viral capsid or envelope carrying a member of a specific binding pair, the counterpart of which is not directly associated with the surface of the target cell. These vehicles can be rendered unable to bind to their natural cell receptor. The targeting conjugates include the counterpart member of the specific binding pair, linked to a targeting moiety which is a cell-type specific ligand (or fragments thereof). The number of the specific binding pair present on the viral vehicles can be, for example, an immunoglobulin binding moiety (e.g., capable of binding to a Fc fragment, protein A, protein G, FcR or an anti-Ig antibody), or biotin, avidin or streptavidin. The virus' outer membrane or capsid may contain a substance which mediates entrance of the gene delivery vehicle into the target cell. Due to the specificity of the ligand, the binding pair's high affinity, and the gene delivery vehicle's inability to be targeted when used alone, the universality of the method for gene delivery, together with its high cell type selectively can be achieved by using various targeting conjugates.

    摘要: The present invention relates to vaccines that are made in transgenic soybeans for use in humans, animals of agricultural importance, pets, and wildlife. These vaccines are used as vaccines against viral, bacterial, fungal, parasitic or prion related diseases, cancer antigens, toxins, and autologous or self proteins. The transgenic soybeans of the instant invention also can be used for inducing tolerance to allergens or tolerance to autoimmune antigens, wherein an individual shows hypersensitivity to said allergen or has developed autoimmunity to autologous or self proteins, respectively. The invention also relates to prophylatically treating individuals and/or populations prior to showing hypersensitivity to allergens. Other aspects of the invention include using the transgenic soybeans as an oral contraceptive, and the expression of protein adjuvants in transgenic soybeans.

    摘要: Methods for enhancing the production of interferons in animal cell culture are described. These methods rely on the manipulation of the cellular levels of certain inducers of interferon production, in particular cellular levels of double-stranded-RNA-dependent kinase (dsRNA-PKR, or PKR). In cell cultures that overproduce PKR, interferon synthesis is induced to high levels, and significant amounts of interferon can be recovered without conventional induction of interferon by virus.
