    摘要: The present invention provides for an immunogenic analogue of a human TNFα protein, wherein said analogue comprises an immunogenized monomeric TNFα polypeptide or TNFα di- or timer, and wherein the analogue further comprises a toxicity reducing or abolishing mutation selected from the group consisting of Y87S, D143N or A145R, the amino acid numbering setting out from the N-terminal valine in human TNFα. The invention also provides for a nucleic acid fragment encoding the analogue as well as to vectors and transformed cells useful in the preparation of the analogue. Also disclosed are methods of down-regulating TNFα in a subject in need thereof.

    摘要: The present invention provides for methods for immunizing actively against autologous carcinoembryonic antigen (CEA). The method encompasses that the immune system is engaged with variant CEA which is either administered as a protein vaccine, or is effected expressed by nucleic acid vaccination or live-viral vaccination. Preferred embodiments include immunization with variants that include at least one foreign T-helper epitope introduced in the CEA sequence. Also disclosed is variant proteins, DNA, vectors, and host cells useful for practising the method of the invention.
