Purpose: The use of small non-coding nucleic acids, such as siRNA and miRNA, has allowed for a deeper understanding of gene functions, as well as for development of gene therapies for complex neurodegenerative diseases, including retinal degeneration. For effective delivery into the eye and transfection of the retina, suitable transfection methods are required. We investigated the use of a lipid-based transfection agent, Invivofectamine® 3.0 (Thermo Fisher Scientific), as a potential method for delivery of nucleic acids to the retina. Methods: Rodents were injected intravitreally with formulations of Invivofectamine 3.0 containing scrambled, Gapdh, Il-1β, and C3 siRNAs, or sterile PBS (contr..
