Viral Transduction

Definition

Viral transduction is the process by which a virus introduces its genetic material into a host cell, hijacking the cell's machinery to produce more viral particles. This process is a key tool used in genetic engineering, allowing researchers to manipulate the genome of organisms by delivering desired genetic material through viral vectors.

5 Must Know Facts For Your Next Test

1. Viral transduction is a highly efficient method for delivering genetic material into target cells, making it a valuable tool in genetic engineering and gene therapy applications.
2. Researchers can engineer viral vectors, such as lentiviruses and adenoviruses, to carry and deliver specific genes or genetic sequences of interest to host cells.
3. The viral vector binds to receptors on the target cell's surface, allowing the viral genetic material to enter the cell and integrate into the host's genome.
4. Viral transduction can be used to introduce new genes, modify existing genes, or silence gene expression in a wide range of cell types, including stem cells, immune cells, and cancer cells.
5. The safety and efficacy of viral transduction techniques are ongoing areas of research, with concerns about potential off-target effects and immune responses to the viral vector.
