<qa>  What is the cause of angiogenesis?Laboratory findings establish that human specimens of Interstitial Lung Diseases including IPF demonstrate an impalance in expression of proteins Th2 Cytokines, CC Chemokines, and CXC Chemokines. When these protein levels are in excess or low, they alter the normal lung mechanism, causing angiogenesis abnormal blood vessel formation, inflammation, scar tissue formation and impaired immunity of the patient. We hope to establish that the efficacy of anti-angiogenetic agent as an add on therapy for IPF patients, will prove to bring stabilization or improvement.
