What delivers the therapeutic gene?

The therapeutic gene is typically delivered using vectors, which can be viral or non-viral in nature. Viral vectors, such as lentiviruses or adenoviruses, are engineered to carry the gene into target cells effectively. Non-viral methods include liposomes, nanoparticles, and electroporation, which facilitate the uptake of the gene by cells without using viruses. The choice of delivery method depends on factors like the target tissue, the type of disease, and the desired duration of gene expression.
