The present invention relates to a polypeptide comprising a component A with at least three tumor necrosis factor (TNF) homology domains of TNF-ligand family members (THD) in which C-terminal and N-terminal reference points are defined by consensus sequences and which are connected through short stretches of additional C-terminal and/or N-terminal amino acids of the THD or variants thereof, and a component B comprising a dimerization domain. Further, the present invention relates to a polypeptide comprising at least three THDs in which C-terminal and N-terminal reference points are defined by consensus sequences and which are connected through short stretches of additional C-terminal and/or N-terminal amino acids of the THD or variants thereof. Further, the invention relates to a nucleic acid comprising said polypeptides, a vector comprising said nucleic acid and a pharmaceutical composition comprising said polypeptides, or said nucleic acids or said vector. Further, the present invention relates to said polypeptides, said nucleic acid or said vector for the use as a medicament or for the use in the diagnosis, prophylaxis or treatment of hyperproliferative disorders and inflammatory disorders.
