Abstract: A method for analyzing the prevention and treatment efficacy of a dendritic cell-derived immunotherapeutic for prostate cancer using an animal model carrying tumors expressing a human prostate cancer-specific antigen includes either administering to a normal non-human animal dendritic cells to be analyzed, or administering to a normal non-human animal a cancer cell line expressing the human prostate cancer-specific antigen to induce cancer in the normal non-human animal; administering to the animal the cancer cell line expressing the human prostate cancer-specific antigen to induce cancer in the animal when the dendritic cell administering step was performed, or administering to the animal with cancer dendritic cells to be analyzed when the human prostate cancer-specific antigen expressing cell line administering step was performed; and determining the prevention and treatment efficacy of the dendritic cells as immunotherapeutics for prostate cancer by measuring the formation or growth of cancer cells origina

Abstract: A method for measuring the activity of cytotoxic T lymphocytes (CTLs) includes preparing peripheral blood mononuclear cells (PBMCs) from blood of an animal; preparing mature dendritic cells by isolating monocytes from the PBMCs, differentiating the monocytes into dendritic cells for presenting an antigen molecule and pulsing dendritic cells with the antigen molecule to obtain the mature dendritic cells; preparing the CTLs as an effector cell by stimulating the PBMCs with the mature dendritic cells to activate and amplify the CTLs; preparing target cells by pulsing the PBMCs, monocytes or B cells with a cytoplasmic transduction peptide (CTP)-antigen complex generated by linking the antigen molecule of step (b) to the CTP; treating the target cells with the effector cells; and analyzing the lysis of the target cells. In addition, a kit for measuring the activity of cytotoxic T lymphocytes is provided.

Abstract: The present invention relates to a cytoplasmic transduction peptide (CTP) showing transduction potential, as well as cytoplasmic remaining potential and various uses thereof. The CTP of this invention exhibits a transduction potential identical or higher than the conventional protein transduction, PTD, and a strong tendency to remain in the cytoplasm, so that it is very useful in inducing cytotoxic T lymphocytes (CTL) and a drug delivery system (DDS) targeting cytoplasm.
