  • Publication number: 20120263710
    Abstract: The present invention relates to the field of pathological angiogenesis and arteriogenesis and, in particular, to a stress-induced phenotype in a transgenic mouse (PIGF?/?) that does not produce Placental Growth Factor (PIGF) and that demonstrates an impaired vascular endothelial growth factor (VEGF)-dependent response. PIGF deficiency has a negative influence on diverse pathological processes of angiogenesis, arteriogenesis and vascular leakage comprising ischemic retinopathy, tumor formation, pulmonary hypertension, vascular leakage (edema formation) and inflammatory disorders. The invention thus relates to molecules that can inhibit the binding of PIGF to its receptor (VEGFR-1), such as monocloncal antibodies and tetrameric peptides, and to the use of these molecules to treat the above-mentioned pathological processes.

  • Publication number: 20110288020
    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.

  • Patent number: 7727971
    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 or nucleic acids ensuring increased expression 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: 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: 6720309
    Abstract: This invention relates to a gene therapy method for inducing pulmonary vasodilation. More specifically, this invention involves introducing the nitric oxide synthase gene into lungs resulting in pulmonary vasodilation. This results in a hypotensive effect in the pulmonary circulation which does not significantly affect systemic blood pressure or cardiac index. This method is useful to treat primary pulmonary hypertension or pulmonary hypertension secondary to various disease states.
