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.

Disclosed are novel methods for increasing muscle mass by means of immunization against Growth Differentiation Factor 8 (GDF-8, myostatin). Immunization is preferably effected by administration of analogues of GDF-8 which are capable of inducing antibody production against homologous GDF-8. Especially preferred as an immunogen is homologous GDF-8 which has been modified by introduction of one single or a few foreign, immunodominant and promiscuous T-cell epitopes while substantially preserving the tertiary structure of the homologous GDF-8. Also disclosed are nucleic acid vaccination against GDF-8 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 GDF-8 analogues, methods for the preparation of analogues and pharmaceutical formulations, as well as nucleic acid fragments, vectors, transformed cells, polypeptides and pharmaceutical formulations.

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.

The present invention relates to implants used for alleviating and/or preventing conditions relating to damaged joints involving articulating surfaces. The implants comprise fibre of polymer and/or metal, and can be used as an artificial joint, as part of an artificial joint or as an artificial joint spacer made to replace the missing cartilage or to improve the slidability between two natural and/or artificial components of the body, or between a natural and artificial component. The product of the invention can be used to partly or entirely coat medical products or to make up implant partly or entirely.
摘要:
A method for modifying the surface of a solid polymer wherein the polymer surface is exposed to an aqueous solution containing a two-ring heterocyclic compound that is described in more detail herein. The polymer and the two-ring heterocyclic compound are irradiated with electromagnetic radiation having a wavelength ranging from about 10 nm to about 400 nm to photochemically immobilize the two-ring heterocyclic compound to the polymer.
