    摘要: The invention relates to the finding that virus like particles (VLPs) can be loaded and packaged, respectively, with DNA oligonucleotides rich in non-methylated C and G (CpGs). If such CpG-VLPs are mixed with antigens, the immunogenicity of these antigens are dramatically enhanced. In addition, the T cell responses against the antigens are especially directed to the Th1 type. Surprisingly, no covalent linkage of the antigen to the VLP is required; it is sufficient to simply mix the VLPs with the adjuvants for co-administration. In addition, it was found that VLPs did not enhance immune responses unless they were loaded and packaged, respectively, with CpGs. Antigens mixed with CpG-packaged VLPs may therefore be ideal vaccines for prophylactic or therapeutic vaccination against allergies, tumors and other self-molecules and chronic viral diseases.

    摘要: The present invention provides novel expression vectors which permit tight regulation of gene expression in eucaryotic cells. More specifically, the invention provides DNA vectors comprising nucleotide sequences that are transcribed to form RNA molecules which are then replicated by a temperature-sensitive replicase to form additional RNA molecules. The RNA molecules produced by replication contain a nucleotide sequence which may be translated to produce a protein of interest or which encode one or more untranslated RNA molecules. Also provided are methods for producing heterologous proteins and untranslated RNA molecules. Further provided are methods for administering heterologous proteins and untranslated RNA molecules to individuals. In addition, pharmaceutical compositions are provided comprising the DNA and RNA molecules of the invention and a pharmaceutically acceptable carrier.

    摘要: Cell cultures are described which proliferate in a serum- and protein-free environment and which are characterized by the circumstance that the concentration of at least one cell-cycle-regulatory protein is increased during at least one period of the cell-cycle. Methods for the production of such cell cultures are presented. With these methods cell lines can be transferred to serum- and protein-free growth that are already in use in a production process which, prior to the use of these methods, requires serum or proteins added to the basal medium.
