Summary
Viral vectors such as AAV and lentivirus deliver therapeutic genes, with safety and immune challenges.
In depth
AAV is small, mostly non-integrating, various serotypes target tissues, cargo limit about 4.7 kb; lentivirus integrates and carries larger cargo; non-viral options include lipid nanoparticles. Immunity to vectors and dose-related toxicity are challenges.
Vector tropism, immunogenicity, cargo size and manufacturing dictate choice. AAV can persist as episomes in non-dividing cells. Lentivirus allows stable integration in blood stem cells.
Key idea: no single vector fits all diseases.
Frequently asked questions
What is Gene Therapy Vectors?
