I attempted to generate the tumor/virus antigen (e.g. Survivin, WT-1, TERT, HCMV-pp65)-specific cytotoxic T lymphocytes (CTLs) and studied for various factors (e.g. adjuvant, CD4+T, Treg cells) which influence propagation of CTLs.
* Technical skills
Isolation of PBMCs from peripheral/cord blood.
Separation of specific cells from PBMCs using MACS system.
Immunological assay; chromium release assay, ELISPOT, ELISA and FACS analysis etc
Cultivation of primary cells such as PBMC (e.g. T, B, NK, Dendritic cells) and cord blood stem cells.

Currently I am developing methodology for ex vivo expansion and activation of NK cells from PBMC (peripheral blood mononuclear cell) and CBMC (cord blood mononuclear cell). I am also attempting the preclinical trials to verify the effect of ex vivo expanded NK cells against tumors.

Dissertation Abstracts
For the adoptive immunotherapy and the study of cytotoxic T lymphocytes (CTLs), efficient in vitro generation of CTLs is needed. However, it is still difficult to induce T cells specific for naďve antigens in vitro even though dendritic cells (DCs) as potent APCs are used. In this study, we investigated quantitative and qualitative effects of CD4+ T cells during in vitro stimulation of CD8+T cells from healthy donors using DCs transduced with adenovirus vector expressing human survivin (Adv-survivin). CTLs were not efficiently induced in the absence of CD4+ T cells or in CD25+ depleted CD4+ T cells. When the ratio of CD4+:CD8+ T cells was quantitatively decreased from 2:1 to 1:2, proliferation of CTLs specific for survivin was gradually increased. Because DCs pulsed with HCMV pp65 protein could activate CD4+ T cells to secrete Th1 cytokines, the use of pp65 protein as an adjuvant induced higher numbers and frequencies of CTLs. Furthermore, Th1 conditioning of CD4+ T cells augmented this generation of CTLs. These results suggest that both quantitative and qualitative modulation of CD4+ T cells including the number and Th1 polarization may be required for the efficient induction of CTLs specific for tumor antigens in vitro.
