摘要:
A modified human TNFα molecule is capable of raising neutralizing antibodies towards unmodified human TNFα following administration of the modified TNFα to a human host, wherein one or more peptide fragments of the human TNFα 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 TNFα-molecule containing at least one TNFα B cell epitope, wherein the substitution introduces a substantial change in the amino acid sequence of any one of the strands of the front β-sheet, in any one of the connecting loops, or in any one of the B′, I, or D strands of the back β-sheet.

The present invention relates to compositions and methods for producing dendritic cells and particularly to compositions and methods for producing immature dendritic cells that are immunocompetent. We describe a method of producing dendritic cells by cultivation of monocytes, characterised by at least one of: pre-treatment of a tissue culture surface with at least one of: a substantially plasma-free and serum-free pre-treatment medium, a pre-treatment medium comprising heparin, and a pre-treatment medium comprising a protein solution; adsorption of monocytes using at least one of: a substantially plasma-free and serum-free adsorption medium; cultivation of monocytes using a substantially plasma-free and serum-free cultivation medium. We also describe compositions including the dentritic cells and uses of the dentritic cells.
摘要:
A method for in vivo down-regulation of amyloid protein in an animal, including a human being, the method comprising effecting presentation to the animal's immune system of an immunogenically effective amount of at least one amyloidogenic polypeptide or subsequence thereof which has been formulated so that immunization of the animal with the amyloidgenic polypeptide or subsequence thereof induces production of antibodies against the amyloidogenic polypeptide, and/or at least one analogue of the amyloidogenic polypeptide wherein is introduced at least one modification in the amino acid sequence of the amyloidogenic polypeptide which has as a result the immunization of the animal with the analogue induces production of antibodies against the amyloidogenic polypeptide.

摘要:
Disclosed are novel methods for combating diseases characterized by deposition of amyloid. The methods generally rely on immunization against amyloidogenic proteins (proteins contributing to formation of amyloid) such as beta amyloid (Aβ). Immunization is preferably effected by administration of analogues of autologous amyloidogenic polypeptides, said analogues being capable of inducing antibody production against the autologous amyloidogenic polypeptides. Especially preferred as an immunogen is autologous Aβ which has been modified by introduction of one single or a few foreign, immunodominant and promiscuous T-cell epitopes while substantially preserving the majority of Aβ's B-cell epitopes. Also disclosed are nucleic acid vaccination against amyloidogenic polypeptides and vaccination using live vaccines as well as methods and means useful for the vaccination. Such methods and means include methods for identification of useful immunogenic analogues of the amyloidogenic proteins, methods for the preparation of analogues and pharmaceutical formulations, as well as nucleic acid fragments, vectors, transformed cells, polypeptides and pharmaceutical formulations.

Disclosed are novel methods and compositions for combating diseases characterized by deposition of amyloid. The methods generally rely on immunization against amyloid precursor protein (APP) or beta amyloid (Aβ). Immunization is preferably effected by administration of analogs of autologous APP or Aβ, said analogs being capable of inducing antibody production against the autologous amyloidogenic polypeptides. Especially preferred as an immunogen is autologous Aβ which has been modified by introduction of one single or a few foreign, immunodominant and promiscuous T-cell epitopes.
