Delivery Vehicles for Genetic Modification
The field of genetic modification employs a variety of carriers to introduce altered genetic material into target cells. These vehicles play a essential role in enabling targeted gene editing and manipulation. Some common types of delivery systems include viral vectors, liposomes, and engineered nanoparticles. Each type possesses unique properties and drawbacks. The choice of system depends on factors such as the target cell type, the size and nature of the genetic construct, and the desired duration of gene expression.
Liposomes can successfully deliver genes into a wide range of cells, but they may induce immune responses or incorporate into the host genome, potentially causing unintended consequences. Engineered nanoparticles offer greater precision and reduced immunogenicity, but their delivery efficiency can be constrained.
