摘要:
A peptide-POD with ability to penetrate and deliver fluorophores, siRNA, DNA and quantum dots to cells in culture and retinal and ocular tissues in vivo is provided herein. POD couples to adenovirus vectors, enhancing tropism for certain cells, potentially providing a safer and more efficacious method to deliver molecules to ocular and other tissues in vivo. POD constructs are therapeutic delivery vehicles for treating cells and tissues, including ocular cells and tissues suffering from retinal degeneration.
摘要:
Adenovirus (Ad) vectors are here provided for treatment of ocular tissues as are suitable methods to transduce photoreceptor (PR) cells, the tissue associated with degeneration. Expression from CMV or chicken beta actin (CBA) promoters in neural retina were compared, and CBA was found to be 173-fold more potent than CMV. Further, the RGD domain in Ad penton was found to play a key role in RPE tropism. Deletion of the RGD domain coupled with the CBA promoter permitted transgene expression in neural retina approximately 667-fold more efficiently than with prior Ad5 vectors. Use of Ad vectors in combination with a 4.7 kb rhodopsin promoter enabled transgene expression exclusively in photoreceptor cells in vivo.
