Abstract

Adeno-associated virus (AAV) vector is a promising platform technology for ocular gene therapy. Recently clinical successes to treat choroidal neovascularization (CNV) in wet type age-related macular degeneration have been reported. However, because pathologic conditions of the retina may alter the tropism of viral vectors, it is necessary to evaluate the transduction efficiency of different serotypes of AAV vectors in the retinas with CNVs. Here, we show the patterns and efficacy of transduction of AAV2, -5, and -8 vectors in a laser-induced CNV mouse model. C57BL/6J mice were subjected to unilateral laser photocoagulation on the right eye to induce CNV 5 days prior to intravitreal injection of AAV2, -5, and -8 capsids expressing EGFP. Transduction was increased around CNV lesions for all AAV capsid types, and AAV2 resulted in the highest transduction efficiency. In the absence of CNV, the AAV2 vector transduced ganglion and inner nuclear layer (INL) cells, and AAV5 and AAV8 transduced only a small proportion of cells in the retinal ganglion cell layer. CNV increased AAV2 vector expression throughout the retina and in and around CNVs; the transduced cells included retinal ganglion cells, Müller cells, cells from the INL and ou...Continue Reading

Cell-Type-Specific Viral Vectors (ASM)

Viral vectors are used in biological research and therapy to deliver genetic material into cells. However, the efficiency of viral vectors varies depending on the cell type. Here is the latest research on cell-type-specific viral vectors.

AAV-based Gene Therapy

Adeno-associated virus (AAV)-based gene therapy is a biological vector that is being researched to be used as a potential therapeutic option. This gene therapy is designed to insert fragments of DNA into targeted cells to help treat diseases, such as hemophilia a. Discover the latest research on AAV-based gene therapy here.
