in dystrophic controls.
As these factors can exert protective effects on retinal neurons [52]--[56] and neurons in other neurodegenerative disease models [49], [57], [58], it seems likely that these substances may contribute to the latent photoreceptor cell survival we observe
in the dystrophic retina.
