Decoding Pre-existing Antibodies Towards AAV Capsids to Optimize Gene Therapy Outcomes

In the dynamic field of gene therapy, understanding the complexities of Adeno-Associated virus (AAV) immunogenicity is crucial for achieving success. Managing pre-existing neutralizing antibodies (NAbs) and Total Antibodies (TAbs) toward AAV capsids poses a significant challenge, potentially compromising treatment outcomes with recombinant vectors.

Recombinant vectors aim for precise gene delivery, yet success depends on overcoming immune barriers, especially pre-existing antibodies recognizing AAV capsids. These antibodies can impede successful gene transfer, hindering therapeutic payload delivery to target cells.

Decoding Pre-existing Antibodies Towards AAV Capsids to Optimize Gene Therapy Outcomes

In the dynamic field of gene therapy, understanding the complexities of Adeno-Associated virus (AAV) immunogenicity is crucial for achieving success. Managing pre-existing neutralizing antibodies (NAbs) and Total Antibodies (TAbs) toward AAV capsids poses a significant challenge, potentially compromising treatment outcomes with recombinant vectors.

Recombinant vectors aim for precise gene delivery, yet success depends on overcoming immune barriers, especially pre-existing antibodies recognizing AAV capsids. These antibodies can impede successful gene transfer, hindering therapeutic payload delivery to target cells.

It's crucial to measure both Neutralizing Antibodies (NAbs) and Total Antibodies (TAbs), since these offer complementary insights into the immune response to AAV vectors. While NAbs directly impact therapy efficacy, total antibodies provide a broader understanding, including potential risks of adverse effects. By assessing both, tailored strategies to overcome immunogenicity challenges and optimize outcomes can be developed.

Two types of pre-existing antibodies:

Neutralizing Antibodies (NAbs): NAbs specifically bind to and neutralize the AAV vector, hindering its delivery of therapeutic genes into target cells. High levels of NAbs can significantly reduce gene therapy efficacy by impeding the vector's ability to reach target cells.
 
Total Antibodies (TAbs): TAb measurement encompasses all antibodies recognizing various parts of the AAV vector, including capsid proteins. Total antibodies provide a comprehensive view of the immune response to the AAV vector, indicating both neutralizing and non-neutralizing antibodies. Monitoring total antibodies helps assess AAV vector immunogenicity and evaluate risks of immune-mediated adverse effects, aiding in treatment optimization.
