Gene therapy holds promising potential in addressing various neurological disorders by delivering therapeutic genes to targeted cells. Among the vectors utilized, recombinant adeno-associated viruses (rAAVs) have emerged as effective vehicles due to their low immunogenicity and ability to transduce both dividing and non-dividing cells. In this article, we delve into the technical aspects and applications of AffiAAV® rAAV-CAG-fDIO-EYFP-WPRE-hGH polyA in the realm of gene therapy and neuroscience research.
rAAV-CAG-fDIO-EYFP-WPRE-hGH polyA Technical Overview
is a proprietary platform that enables enhanced tissue-specific targeting and transgene expression, crucial for optimizing gene therapy outcomes. The rAAV-CAG-fDIO-EYFP-WPRE-hGH polyA construct represents a sophisticated design tailored for robust and sustained gene expression in neural cells.
The CAG (Cytomegalovirus early enhancer/chicken beta-actin promoter) promoter ensures strong and ubiquitous expression across various cell types, including neurons and glial cells, essential for addressing the heterogeneity of neurological disorders. The fDIO (flip-excision) switch enables conditional expression, allowing precise temporal control of transgene activation or silencing, thus minimizing off-target effects.
The incorporation of EYFP (Enhanced Yellow Fluorescent Protein) facilitates visualization and tracking of transduced cells, facilitating in vivo monitoring of gene expression and cell fate. Furthermore, the Woodchuck Hepatitis Virus Posttranscriptional Regulatory Element (WPRE) and human Growth Hormone (hGH) polyadenylation signal enhance mRNA stability and translational efficiency, respectively, ensuring prolonged and robust transgene expression in target cells.
