Specific recognition of NY-ESO-1 p94-102 and Ad2/ESO-transfected APCs. ELISPOT analysis of the recognition by NY-ESO-1 p94-102 peptide-presensitized NW1539 CD8+ T cells of autologous, monocyte-derived APCs infected with wild-type or NY-ESO-1 adenovirus (30 pfu/cell) or pulsed with either 1 µg NY-ESO-1 and 1 µg SSX protein, a lysate of the NY-ESO-1+ melanoma cell line NW-MEL-38 or NY-ESO-1 p94-102 peptide (10 µg/ml).
