Publication number: 20090074765Abstract: 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 monoclonal antibodies and tetrameric peptides, and to the use of these molecules to treat the above-mentioned pathological processes.Type: ApplicationFiled: November 5, 2008Publication date: March 19, 2009Applicants: VLAAMS INTERUNIVERSITAIR INSTITUUT VOOR BIOTECHNOLOGIE VZW (VIB), LIFE SCIENCES RESEARCH PARTNERS VZW (LSRP)Inventors: Peter CARMELIET, Desire Collen, Sandro De Falco, Ruvo Menotti

Patent number: 7341992Abstract: 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.Type: GrantFiled: May 24, 2002Date of Patent: March 11, 2008Assignees: Vlaams Interuniversitair Instituut Voor Biotechnologie VZW, D.

Patent number: 7291458Abstract: Methods of activating a signaling cascade comprising, introducing leptin and/or a cytokine to a receptor complex comprising gp 130, optionally in combination with a compound acting on adenylate cyclase or acting on one or more downstream targets of adenylate cyclase, thereby inducing genes in neuro-endocrine cells or cells of neuro-endocrine origin. Two distinct gene-sets are induced, immediate early response genes (STAT-3, SOCS-3, Metallothionein-II, the serine/threonine kinase Fnk and the rat homologue of MRF-1), and late induced target genes (Pancreatitis Associated Protein I, Squalene Epoxidase, Uridinediphosphate Glucuronyl Transferase and Annexin VIII). Strong co-stimulation with the adenylate cyclase activator forskolin was shown with respect to late induced target genes. Transcripts encoding Leptin Induced Protein I (LIP-I) and Leptin Induced Protein II (LIP-II) were identified; however, no forskolin co-stimulatory effect was observed.Type: GrantFiled: September 4, 2002Date of Patent: November 6, 2007Assignee: Vlaams Interuniversitair Instituut Voor Biotechnologie VZWInventors: Daniel Broekaert, Joël S.

Publication number: 20070254371Abstract: The invention provides reagents and methods for the accurate quantification of proteins in complex biological samples. Quantification is obtained by adding to a sample a peptide combo, which is essentially a collection of synthetic reference peptides. The synthetic reference peptides have a small mass difference when compared to the biological reference peptides that originate upon digestion from the proteins present in the sample. Reference peptides and synthetic reference peptides are selected and the identity and accurate amounts of reference peptides are determined by mass spectrometry. The methods can be used in high throughput assays to interrogate proteomes.Type: ApplicationFiled: December 16, 2005Publication date: November 1, 2007Applicants: Vlaams Interuniversitair Instituut Voor Biotechnologie VZW, Universiteit GentInventors: Koen Kas, Joel Vandekerckhove, Luc Krols

Patent number: 7226908Abstract: 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.Type: GrantFiled: April 12, 2001Date of Patent: June 5, 2007Assignees: Vlaams Interuniversitair Instituut Voor Biotechnologie VZW, Collen Research Foundation VZWInventors: Peter Carmeliet, Désiré Collen, Bert Oosthuyse
