Neuron-specific TGF-beta signaling deficiency results in retinal detachment and cataracts in mice
(2007) In Biochemical and Biophysical Research Communications 352(2). p.418-422- Abstract
- We generated a mouse model (cKO) with a conditional deletion of TGF-beta signaling in the retinal neurons by crossing TGF-beta receptor I (TGF-beta RI) floxed mice with nestin-Cre mice. Almost all of the newborn cKO mice had retinal detachment at the retinal pigment epithelium (RPE)/photoreceptor layer junction of the neurosensory retina (NSR). The immunostaining for chondroitin-6-sulfate showed a very weak reaction in cKO mice in contrast to intense staining in the photoreceptor layer in wild-type mice. Macroscopic cataracts, in one or both eyes, were observed in 50% of the mice by 6 months of age, starting as early as the first month after birth. The cKO mouse model demonstrates that the TGF-beta signaling deficiency in retinal cells... (More)

The cKO mouse model demonstrates that the TGF-beta signaling deficiency in retinal cells leads to decreased levels of chondroitin sulfate proteoglycan in the retinal interpho to receptor matrix. This in turn causes retinal detachment due to the loss of adhesion of the NSR to RPE. (c) 2006 Elsevier Inc. All rights reserved. (Less)
