Abstract: The present invention refers to the selection, isolation and purification of proteins belonging to variable regions named VHNAR or vNAR, originated from IgNAR-type immunoglobulins of elasmobranches with antigen receptor abilities. The clones from which they originate are named VEGFvNAR V32R and V19; and the antibodies are named V32R and V19. Their amino acid sequences and tertiary structures were elucidated, and their ability to neutralize the vascular endothelial growth factor (VEGF) activity was determined. During the development of the invention these proteins were optimized for expression in a production model of E. coli at industrial level. The invention involves the use of these antibodies in general to treat conditions related to angiogenesis or neovascularization and in particular to treat neovascularization-related ophthalmic conditions by topical administration.

Abstract: The present invention concerns therapeutic compositions containing proteins that are the variable regions of IgNAR immunoglobulins, denominated vNAR, that specifically bind and neutralizes cytokines involved in a diversity of process such as inflammation and neovascularization, its ability to reach, bind, and neutralize the activity of one antigenic molecule localized in an immunoprivileged organs, are also described.
