Abstract

Children born with defective heart valves require multiple donor valve replacements throughout life, because these cannot grow and can cause early failure through immune degeneration. This study tests the lentiviral delivery of viral immune evasion genes US2 and human serpin 9 to shield human heart valves from immune rejection. The results show we can efficiently down-regulate human leukocyte antigen expression in heart valve cells and in intact heart valve tissue resulting in decreased activity of a human leukocyte antigen–reactive CD8+ T-cell clone without inducing cytotoxicity. This study demonstrates immune shielding of human heart valves and brings us closer to a durable valve graft in pediatric patients.
