Abstract

PMDC05, a leukemic plasmacytoid dendritic cell (pDC) line which was established in our laboratory, showed a capacity of generating antigen-specific cytotoxic T lymphocytes (CTLs). In order to enhance an antigen presenting ability of PMDC05, PMDC05 was transduced with CD80 gene by lentiviral vector, which was named as PMDC11. PMDC11 displayed a strong antigen presenting ability even without any stimulation, and by culturing with stimulators such as calcium ionophore PMDC11 gained a more potent antigen presenting ability. Our data suggested PMDC11 could be applied as antigen presenting cells more efficiently in adoptive cellular immunotherapy for tumors and severe infections in comparison with PMDC05.
