Advances in Viral Vector-Mediated Mouse In Vivo Transfection
Viral vectors remain among the most efficient tools for delivering genetic material in mouse in vivo transfection studies. Their natural ability to infect cells and deliver payloads enables high transduction efficiency and stable gene expression.
Common viral vectors include lentivirus, adenovirus, and adeno-associated virus (AAV). Lentiviral vectors integrate into the host genome, allowing long-term expression, useful for generating stable knockdown or overexpression models. Adenoviral vectors provide transient but robust transgene expression without integration, ideal for short-term studies. AAV vectors offer low immunogenicity and can transduce dividing and non-dividing cells, making them suitable for diverse tissues including muscle and brain.
Each vector system has specific tropism dictated by surface proteins, influencing tissue targeting. Genetic engineering of viral capsids expands tropism and improves specificity. Self-complementary AAV vectors accelerate transgene expression onset.
Challenges include host immune responses, vector production scalability, and insertional mutagenesis risk. Advances in vector design and manufacturing have improved safety and transduction efficiency.
