Inhibitors of placental growth factor for the treatment of pathological angiogenesis, pathological arteriogenesis, inflammation, tumor formation and/or vascular leakage

摘要

The present invention relates to the field of pathological angiogenesis and arteriogenesis. in particular, 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, tumour formation, pulmonary hypertension, vascular leakage (oedema formation) and inflammatory disorders. Molecules that can inhibit the binding of PIGF to its receptor (VEGFR-1), such as monoclonal antibodies and tetrameric peptides. Further, the use of these molecules to treat the latter pathological processes.
