Abstract: A method is disclosed for inducing cell-mediated immunity against cellular antigens. More specifically, the invention provides for a method for inducing cytotoxic T-lymphocyte immunity against weak antigens, notably self-proteins. The method entails that antigen presenting cells are induced to present at least one CTL epitope of the weak antigen and at the same time presenting at least one foreign T-helper lymphocyte epitope. In a preferred embodiment, the antigen is a cancer specific antigen, e.g. PSM, Her2, or FGF8b. The method can be exercised by using traditional polypeptide vaccination, but also by using live attenuated vaccines or nucleic acid vaccination. The invention furthermore provides immunogenic analogues of PSM, Her2 and FGF8b, as well as nucleic acid molecules encoding these analogues. Also vectors and transformed cells are disclosed. The invention also provides for a method for identification of immunogenic analogues of weak or non-immunogenic antigens.

Abstract: A modified human TNF? molecule is capable of raising neutralizing antibodies towards unmodified human TNF? following administration of the modified TNF? to a human host, wherein one or more peptide fragments of the human TNF? molecule has been substituted by one or more peptides containing immunodominant T cell epitopes or a truncated form of the molecule containing the immunodominant epitope and one or both flanking regions of the human TNF?-molecule containing at least one TNF? B cell epitope, wherein the substitution introduces a substantial change in the amino acid sequence of any one of the strands of the front ?-sheet, in any one of the connecting loops, or in any one of the B?, I, or D strands of the back ?-sheet.

Abstract: Biologically active peptides and nucleic acids are identified by a method comprising the following steps: (a) production of a pool of appropriate vectors each containing totally or partly random DNA sequences, (b) efficient transduction of said vectors into a number of identical eukaryotic cells in such a way that a single ribonucleic acid and possibly peptide is expressed or a limited number of different random ribonucleic acids and peptides are expressed by each cell, (c) screening of said transduced cells to see whether some of them have changed a certain phenotypic trait, (d) selection and cloning of said changed cells, (e) isolation and sequencing of the vector DNA in said phenotypically changed cells, and (f) deducing the ribonucleic acid and peptide sequences from the DNA sequence. The peptide sequences may be introduced into or fused to a larger protein, preferably an antibody molecule or a fragment thereof.

Abstract: A library is composed of viral vectors in which each of the vectors (a) involves a peptide expression cassette containing a random nucleotide sequence, (b) transduces a eukaryotic cell to allow expression of the random nucleotide sequence, and (c) is produced by (i) conventional random oligonucleotide synthesis or (ii) random codon synthesis where codons encode an even distribution of random amino acids.
