    摘要: A polypeptide self-antigen useful in a tumor-specific vaccine mimics one or more epitopes of an antigen uniquely expressed by cells of the tumor. The polypeptide is preferably produced in a plant that has been transformed or transfected with nucleic acid encoding the polypeptide and is obtainable from the plant in correctly folded, preferably soluble form without a need for denaturation and renaturation. This plant-produced polypeptide is immunogenic without a need for exogenous adjuvants or other immunostimulatory materials. The polypeptide is preferably an scFv molecule that bears the idiotype of the surface immunoglobulin of a non-Hodgkin's (or B cell) lymphoma. Upon administration to a subject with lymphoma, the plant-produced, tumor-unique scFv polypeptide induces an idiotype-specific antibody or cell-mediated immune response against the lymphoma.

    摘要: We describe here an in vitro method of increasing complementarity in a heteroduplex polynucleotide sequence. The method uses annealing of opposite strands to form a polynucleotide duplex with mismatches. The heteroduplex polynucleotide is combined with an effective amount of enzymes having strand cleavage activity, 3′ to 5′ exonuclease activity, and polymerase activity, and allowing sufficient time for the percentage of complementarity to be increased within the heteroduplex. Not all heteroduplex polynucleotides will necessarily have all mismatches resolved to complementarity. The resulting polynucleotide is optionally ligated. Several variant polynucleotides result. At sites where either of the opposite strands has templated recoding in the other strand, the resulting percent complementarity of the heteroduplex polynucleotide sequence is increased. The parent polynucleotides need not be cleaved into fragments prior to annealing heterologous strands. Therefore, no reassembly is required.

    摘要: Herein described are various methods for making a vaccine that are made of re-assembled virus like particles (VLP). First, the VLPs are disassembled into coat proteins or encapsidation intermediate populations. Each population undergoes, for instance, chemical conjugation of unique peptide or nucleic moieties to form separate populations. Thereafter, a predetermined amount of each of the several (one or more) different coat proteins or encapsidation intermediates from the different populations is mixed and joined, forming intact VLPs, surrounding a nucleic acid core, that are composed of different coat proteins such that the reassembled VLP displays more than one peptide or other molecule. The nucleic acid can function either as a scaffold alone or can be engineered for the expression of an immunomodulatory protein in a eukaryotic cell.
