  • a Lymphocytes from regional lymph nodes and spleen were harvested 10 days after intramuscular infection with AAVlacZ and adoptive transfer of 5 × 106APCs infected ex vivo with AdlacZ (group 5), AdBglII (group 7), AAVlacZ (group 8), or AAVlacZ plus AdBglII (group 9) and mock infected (group 6). Cells were restimulated with purified β-galactosidase (β-Gal), AAVlacZ (AAVlacZ), UV-inactivated adenovirus type 5 (Ad5), or medium (Mock) for 48 h, and the supernatants were assayed for the secretion of IL-10 and IFN-γ by cytokine ELISA. A representative experiment is shown; this study was repeated twice with identical results.
