A potential new way to treat some of the most common blinding diseases

Many eye diseases, including diabetic retinopathy and macular degeneration, exhibit increased permeability of blood vessels in the macular (central) portion of the retina leading to abnormal fluid accumulation and vision loss. Therapies targeting a specific cytokine, vascular endothelial growth factor (VEGF), have transformed clinical care; however, not all patients respond well. A new report in The American Journal of Pathology shows that inhibiting a specific signaling molecule, atypical protein kinase C (aPKC), either genetically or pharmacologically, reduces increased vessel permeability and blocks inflammation. Blocking aPKC may help protect vision in patients with potentially blinding eye diseases.
