This study shows that TRPC5 is an important negative regulator of retinal ganglion cell (RGC) axonal outgrowth and an important regulator of neurite remodeling. The authors hypothesize that TRPC5 senses abnormal intraocular pressure changes and contributes to the death of RGCs in disease. In glaucoma, for example, excessive Ca2+ entry through TRPC5 might induce dendritic and axonal remodeling, which could lead to cell death.
