gene delivery vector
Noun: A gene delivery vector is a biological or synthetic agent used to transport foreign genetic material, such as DNA or RNA, into the interior of a target cell. Its primary function is to facilitate the introduction, or "delivery," of new genes into cells for purposes like gene therapy, research, or genetic modification.
The term is used in genetics, molecular biology, and medical research to describe the carrier system for gene transfer. - Scientists are developing a new gene delivery vector based on a modified virus. - The efficiency of the therapy depends heavily on the chosen gene delivery vector.
- "Viral vector": A common type of gene delivery vector that uses a modified virus (e.g., adenovirus, lentivirus) stripped of its disease-causing ability to carry therapeutic genes.
- Adeno-associated virus is a widely studied viral gene delivery vector.
- "Non-viral vector": A synthetic or chemical vector, such as lipid nanoparticles or polymers, used to deliver genes without using viral components.
- Lipid nanoparticles have emerged as a promising non-viral gene delivery vector for mRNA vaccines.
- Vector (n): In biology, any agent that acts as a carrier. A gene delivery vector is a specific type of vector.
- Transfection agent (n): A substance used to introduce nucleic acids into cells; often synonymous with non-viral gene delivery vectors.
- Gene therapy vehicle (n): A less technical term sometimes used to describe a gene delivery vector.
- Gene carrier
- Gene transfer vehicle
- Transduction vector (specifically for viral delivery)
- Vector design: The process of engineering and optimizing a gene delivery vector.
- The lab's focus is on improving vector design for greater safety.
- Vector tropism: The specificity of a gene delivery vector for certain cell or tissue types.
- Modifying the viral coat proteins can alter the vector tropism.
The concept is central to modern biotechnology and medicine. The choice of vector (viral vs. non-viral) involves trade-offs between delivery efficiency, safety, cargo capacity, and immune response.
