Understanding Viral Vectors

Viral vectors are tools commonly used by molecular biologists to deliver genetic material into cells. This process can be performed inside a living organism (in vivo) or in cell culture (in vitro). Viruses have evolved specialized molecular mechanisms to efficiently transport their genomes inside the cells they infect.

Key Types of Viral Vectors

1. Retroviruses: These can integrate their genetic material into the host genome.
2. Adenoviruses: These do not integrate but can cause a strong immune response.
3. Adeno-associated viruses (AAV): Known for their safety and long-term expression.

Research in this field is rapidly advancing, offering new hope for treating genetic disorders.
