Innovation in the field of gene therapy has opened up promising avenues for treating various genetic disorders. One of the key breakthroughs contributing to the success of gene therapy is the development of viral vectors. These indispensable tools act as vehicles for delivering therapeutic genes into target cells and have allowed scientists to harness the potential of gene therapy.
Viral vector construction plays a crucial role in gene delivery. Among the different types of viral vectors, lentiviral vectors and AAV vectors have gained significant attention due to their efficient and safe delivery mechanisms. Let's delve into the construction process of these viral vectors.
Lentiviral vectors are derived from lentivirus, a type of retrovirus known for its ability to infect both dividing and non-dividing cells. The construction of lentiviral vectors involves removing the viral genes responsible for replication and pathogenesis while retaining the essential genes for packaging. Subsequently, the therapeutic gene of interest is inserted into the vector, replacing the removed viral genes.
Adeno-associated virus (AAV) vectors have emerged as another popular choice for gene delivery due to their non-pathogenic nature and long-term gene expression. AAV vector construction involves the insertion of the therapeutic gene into a plasmid, which is then co-transfected into host cells along with AAV helper genes. The helper genes facilitate the replication and packaging of the AAV vector, resulting in the production of recombinant AAV particles carrying the therapeutic gene.
Viral vector construction serves as the foundation for successful gene delivery in gene therapy. By utilizing efficient delivery vehicles like lentiviral vectors and AAV vectors, scientists can overcome the barriers of cell type specificity and immune response to achieve targeted and long-lasting gene expression.
