NCIt definition : Peripheral blood lymphocytes (PBL) harvested from host blood and stimulated in vitro
with tumor-specific gp 100 antigen. 'Pulsing' PBL with gp100, a tumor associated antigen
(TAA) commonly expressed by melanoma cells, may increase melanoma-reactive cytotoxic
lymphocytes (CTL) in the PBL cell population. Autologous gp100-pulsed PBL have been
administered to melanoma patients in order to augment cytotoxic immune responses to
melanoma. (NCI04);
