Research in the laboratory of Brian D. Perkins, PhD, uses zebrafish and induced pluripotent stem cell (iPSC) models to study photoreceptor degeneration and regeneration.

Inherited retinal diseases lead to irreversible loss of rod and cone photoreceptors and frequently result in blindness. Leber’s Congenital Amaurosis (LCA) is the most common blinding disorder in children. Unfortunately, the body has no way to replace those cells once they are gone. Mutations in the gene for Centrosomal Protein of 290 kDa (CEP290) are one of the leading causes of LCA, as well as other ciliopathies such as Joubert Syndrome (JBTS) and Bardet-Biedl Syndrome (BBS). Importantly, photoreceptor degeneration is one of the most common manifestations in ciliopathies. The long-term goals of this laboratory are to understand the mechanisms regulating the formation of photoreceptor outer segments and to understand how to regenerate photoreceptors in genetic models of retinal degeneration. Our laboratory utilizes a complementary approach of zebrafish mutants in cep290 and several other cilia genes, as well as 3D retinal cups generated from patient-derived human iPSCs. Zebrafish cep290 mutants undergo retinal degeneration and we are exploring the mechanisms that lead to photoreceptor loss and attempting to identify signals that can trigger regeneration in these mutant zebrafish. We are also using iPSCs created from patients with CEP290 mutations to make retinal organoids (also known as “retinas-in-a-dish”) in order to establish the mechanisms that determine disease severity. Our goal is to combine knowledge from stem cell derived retina and zebrafish to develop better therapies for LCA patients in order to restore vision.

Lay Summary

The goal of my laboratory is to understand what causes the rods and cones of the retina die in genetic forms of blindness.  We use zebrafish as a model to study inherited eye disorders in humans.  Specifically, we are investigating zebrafish with mutations in the gene cep290, as mutations in this gene are a major cause of Leber Congenital Amaurosis (LCA), an inherited form of childhood blindness.
