CK1 Inhibition Offers New Path to Protect Central Vision

Scientists screened ~2,700 compounds in ~20,000 human retinal organoids and found that inhibiting casein kinase 1 (CK1) protects cone photoreceptors from degeneration, a key factor in vision loss from diseases like macular degeneration. Some compounds were harmful, but two kinase inhibitors consistently preserved cone cells across stress conditions and were validated in a mouse model. The team also released a detailed open dataset on tested compounds and targets to accelerate retinal research and development of safer, central-vision therapies.
