Antibodies that specifically bind to TrkB and methods for using the same are described. Neuroprotective
agonist antibodies are described, as indicated by their effect on enhancing the survival of
retinal ganglion cells
in vitro, and these
agonist antibodies may be used to treat eye disorders, such as
glaucoma. Additionally, other neuronal diseases or disorders, including those characterized by partial
neuronal damage, benefit from treatment using these
agonist antibodies. In certain embodiments, the present invention comprises antibodies that bind to TrkB and mediate
cell signaling. The antibodies of the present invention may be whole human, non-natural antibodies formulated as injectable excipients.
