Recovery of visual functions in a mouse model of Leber congenital amaurosis.
The visual process is initiated by the photoisomerization of 11-cis-retinal to all-trans-retinal. For sustained vision the 11-cis-chromophore must be regenerated from all-trans-retinal. This requires RPE65, a dominant retinal pigment epithelium protein. Disruption of the RPE65 gene results in massive accumulation of all-trans-retinyl esters in the retinal pigment epithelium, lack of 11-cis-reti...
متن کاملPharmacological and rAAV Gene Therapy Rescue of Visual Functions in a Blind Mouse Model of Leber Congenital Amaurosis
BACKGROUND Leber congenital amaurosis (LCA), a heterogeneous early-onset retinal dystrophy, accounts for approximately 15% of inherited congenital blindness. One cause of LCA is loss of the enzyme lecithin:retinol acyl transferase (LRAT), which is required for regeneration of the visual photopigment in the retina. METHODS AND FINDINGS An animal model of LCA, the Lrat-/- mouse, recapitulates c...

متن کاملDifferential Proteomics and Functional Research following Gene Therapy in a Mouse Model of Leber Congenital Amaurosis
Leber congenital amaurosis (LCA) is one of the most severe forms of inherited retinal degeneration and can be caused by mutations in at least 15 different genes. To clarify the proteomic differences in LCA eyes, a cohort of retinal degeneration 12 (rd12) mice, an LCA2 model caused by a mutation in the RPE65 gene, were injected subretinally with an AAV vector (scAAV5-smCBA-hRPE65) in one eye, wh...
متن کاملDisc oedema in congenital amaurosis of Leber.
Since it was first described by Theodor Leber as 'pigmentary retinitis with congenital amaurosis' (Leber, I867), the entity which bears his name has been the subject of sporadic reports defining its clinical and pathological characteristics. It accounted for about io per cent of the blindness in Sweden (Alstrom and Olsen, 1957) and i8 per cent among children in a series in Holland (SchappertKim...
