Research Description:
Glaucoma is characterized by retinal ganglion cell loss and optic nerve degeneration resulting in insidious vision loss. It is the leading cause of irreversible blindness worldwide. Elevated intraocular pressure is a well-known risk factor, and intraocular pressure reduction is the predominant therapy for slowing disease progression. Because glaucoma can continue to progress in many patients despite intraocular pressure normalization, new therapies targeting pathogenic mechanisms other than intraocular pressure are needed to prevent vision loss.
The Cui lab is actively evaluating GLP-1 receptors agonists, a class of diabetic and weight loss medication, as neuroprotective agents in glaucoma (Sterling et al. Cell Reports. 2020; Sterling et al. Br J Ophthalmol. 2021). In collaboration with the lab of Joshua Dunaief, we showed iron chelation is effective for rescuing retinal ganglion cells and promoting optic nerve axon survival in an animal model of glaucoma.
