  • Publication number: 20100303866
    Abstract: The present invention provides novel peptides and homologues thereof. The peptides of the invention comprise (i) a T-cell epitope of an antigen (self or non-self) with a potential to trigger an immune reaction presented by a class II major histocompatibility complex (MHC) determinant and recognised by CD4+ T cell more specifically of an allergen or auto-antigen, coupled, optionally through the use of a linker to (ii) an amino acid sequence having a reducing activity, such as a thioreductase sequence. The peptides of the invention have been shown to be useful a medicine, more in particular for the prevention or treatment of immune disorders, more specifically of allergic disorders or autoimmune diseases. The present invention thus provides for the use of said peptides for the manufacture of a medicament for the prevention or treatment of an immune disorder and further provides for methods of treatment or preventing immune disorders by using said peptides.

  • Patent number: 7595052
    Abstract: The present invention is related to a method for modulating the immune system of a mammal patient towards an allergen, which comprises the step of inducing a pre-sensitisation of the immune system of said patient towards an immunogen carrying at least one T cell epitope homologous and functionally similar to an epitope present on said allergen and deriving from a naturally-occurring antigen in order to modify the response of said patient to a further sensitisation to said allergen, allowing that the immune response towards the allergen is modulated and that no allergy towards said allergen will be developed in said patient.

  • Patent number: 7582296
    Abstract: The present invention discloses anti-idiotypic antibodies and fragments thereof against inhibitory Factor VIII anti-bodies, said inhibitory antibodies having an affinity for the C2 domain of Factor VIII. The anti-idiotypic antibodies of the present invention are able to completely neutralise in vitro and in an in vivo mouse model the inhibitory activity of FVIII inhibitors. The anti idiotypic antibodies of the present invention can be applied for the prevention, treatment or reduction of bleeding disorders of hemophilia patients with inhibitory antibody against the C2 domain of Factor VIII.

  • Publication number: 20080279906
    Abstract: The present invention relates to the treatment of motoneuron diseases. More particularly the invention relates to the treatment of amyotrophic lateral sclerosis (ALS). It is found that the intracerebroventricular delivery of low amounts of vascular endothelial growth factor into a preclinical ALS animal model induces a significant motor performance and prolongation of survival time of said animals.

  • Patent number: 7357929
    Abstract: This invention relates to antagonists of placental growth factor and signalling thereof, pharmaceutical compositions containing such antagonists and the use of such antagonists to prevent bone loss or bone mass and to enhance bone healing including the treatment of conditions which present with low bone mass and/or bone defects in vertebrates, and particularly mammals, including humans.

  • Patent number: 7341992
    Abstract: The in vivo role of the N-terminal lectin-like domain of thrombomodulin was studied by using homologous recombination in murine ES cells to create mutant mice that lack this region of thrombomodulin. Phenotypic analysis shows that said mice respond identically to their wild type littermates following pro-coagulant challenges meaning that the protein C pathway is not altered by the mutation. However, following several inflammatory stimuli, it was observed that the mutant mice showed an elevated neutrophil extravasation in several organs. It is found that leukocyte adhesion could be abrogated by addition of recombinant lectin-domain meaning that said domain has direct anti-inflammatory properties which means that the lectin-like domain can be used to manufacture a medicament useful for the treatment of a variety of inflammatory disease processes.

  • Patent number: 7226908
    Abstract: The present invention relates to neurological and physiological dysfunction associated with neuron disorders. In (particular, the invention relates to the involvement of vascular endothelial growth factor (VEGF) and homologues in the aetiology of motor neuron disorders. The invention further concerns a novel, mutant transgenic mouse (VEGFm/m) with a homozygous deletion in the hypoxia responsive element (HRE) of the VEGF promoter which alters the hypoxic upregulation of VEGF. These mice suffer severe adult onset muscle weakness due to progressive spinal motor neuron degeneration which is reminiscent of amyotrophic lateral sclerosis (ALS)—a fatal disorder with unknown aetiology. Furthermore, the neuropathy of these mice is not caused by vascular defects, but is due to defective VEGF-mediated survival signals to motor neurons.

  • Publication number: 20060210532
    Abstract: Described are methods of modulating stem/progenitor cell recruitment involving molecules that agonize the formation of plasmin stimulating the recruitment of stem/progenitor cells, including hematopoietic and endothelial precursor cells. Conversely, antagonists of plasmin can inhibit recruitment of the stem cells. In addition, the identification of the uPA receptor (uPAR) as a retention signal for stem cells in their niche suggests a novel method for increased engraftment and isolation of multipotent stem cells.

  • Patent number: 7105168
    Abstract: The present invention relates to prevention and treatment of strokes and ischemic diseases and to post-ischemic therapeutic treatment. The invention furthermore relates to the use of a growth factor for treating, more particularly restoring the function of ischemic tissue, in particular muscles such as myocardium and skeletal muscles.

  • Patent number: 7067313
    Abstract: The present invention comprises ligands and methods of manufacture thereof as well as pharmaceutical preparations including the ligands. The ligands may be human or humanized monoclonal antibodies and fragments, derivatives and homologs thereof. These may exhibit an unforeseen “plateau effect”, i.e. the achievement of only a partial inactivation of a factor involved in hemostasis, in particular in the coagulation cascade, either individually or in combination even in molar excess. The ligands may bind to a factor or a complex of factors resulting in only partially impairing the function of a physiologically functional site of the said factor or factor complex even in molar excess. This makes the ligands particularly suitable for treating coagulation disorders and resulting thrombotic pathologic conditions while minimizing the risk of bleeding.
