Delivery Vehicles for Genetic Modification
The field of genetic modification relies on a variety of vectors to introduce modified genetic material into target cells. These systems play a crucial role in enabling targeted gene editing and manipulation. Some common classes of delivery vectors include viral vectors, vectors in genetic engineering liposomes, and engineered nanoparticles. Each type presents unique advantages and drawbacks. The choice of system depends on factors such as the target cell type, the size and nature of the genetic material, and the desired duration of gene expression.
Nanoparticles can successfully deliver genes into a wide range of cells, but they may initiate immune responses or insert into the host genome, potentially causing unintended consequences. Synthetic nanoparticles offer greater targeting and reduced immunogenicity, but their transfection efficiency can be constrained.
