Adeno-associated Virus (AAV) versus Immune Response.

ABSTRACT: Decades ago, Friedmann and Roblin postulated several barriers to gene therapy, including tissue targeting, delivery across the blood⁻brain barrier (BBB), and host immune responses. These issues remain pertinent till today. Since then, several advances have been made in elucidating structures of adeno-associated virus (AAV) serotypes, antibody epitopes, and ways to modify antibody-binding sites. AAVs capsid has also been engineered to re-direct tissue tropism, reduce ubiquitination, and promote passage across the BBB. Furthermore, the use of high(er) dose recombinant AAV (rAAV) has been accompanied by a better understanding of immune responses in both experimental animals and early clinical trials, and novel work is being performed to modulate the immune response. While the immune responses
