Cross-Presentation of Adeno-Associated Virus Serotype 2 Capsids Activates Cytotoxic T Cells But Does Not Render Hepatocytes Effective Cytolytic Targets
26 Feb 2007
Abstract excerpt
Liver toxicity observed in a clinical trial of adeno-associated virus serotype 2 (AAV2) delivered systemically to patients with hemophilia was ascribed to killing of vector-transduced hepatocytes by capsid-specific T cells. This study evaluated the biology of T cell activation in response to AAV capsids in murine models. CD8(+) T cell epitopes were mapped to capsids from AAV2, AAV7, and AAV8. A tetramer generated...
