Age-related retinal degeneration

Senescent CCL2-/- mice are shown to develop cardinal features of human age-related macular degeneration (AMD). Loss-of-function single nucleotide polymorphisms within CX3CR1 are also associated with age-related macular degeneration (AMD). We generated mice deficient in both genes. The genetic targeted mice spontaneously developed AMD-like retinal lesions such as drusen formation, choroidal neovascularization, A2E accumulation in the retinal pigment epithelium (RPE), and complement deposits in the Bruch's membrane. (Tuo, et al. Invest Ophthalmol Vis Sci 2007;48:3827-36.)
